"Sorta." He shrugged, "None of the guys she went out with got very far, so far as I know. She might spill too much information all the time around you and me, but she was even hesitant about handholding."

Katie grinned at him, "Didya know she's bi?"

"What?" Will seemed completely side-swiped by the revelation.

She shrugged, "Well, yeah. A lot of those boyfriends were side pieces. Cover acts. Suzie didn't laugh and tease some of my friends by stealing their food, pinching butts, and chasing them down to tickle them just because that was the way she acts. Some of it was. Other times... Well, she's cute with her girlfriends."

He looked at her suspiciously. "And you were mad I had a one night stand. When did you sleep with her?"

"Doesn't count. I'm the little sister, you're the big brother." She said haughtily, before giggling. "Fine. Uh... My eighteenth? She made herself my birthday present?"

Will shook his head, "I had no idea you were bi, Katie. Sorry I missed it."

"I'm not." She laughed at his takeaway and splashed him, "Cool it with the fantasies. It was a phase. Like the fedoras and Hitchcock movies. I grew out of it. She didn't. Don't worry, no girl is stealing me away from you. Suzie and I were just... Each other's firsts. I decided I liked boys, she decided she didn't have a preference."

He nodded slowly, "You know... You two as an item... You'd be fucking hot. Like if you kissed her at the Open, everyone would publish the photos. Couldn't help themselves. Lesbian power couple takes Melbourne by storm!"

Katie pouted, "I can't kiss you if I win. Shit. There goes one fantasy I didn't even know I had."

"You could make her your cover."

She glared at him, "Could your mind stop jerking off to the picture of my best friend face-deep in my twat, please?"

"Yeah, I don't think so." He shook his head, "Girl I'm dating, girl I wanted to date. It's a powerful image."

Well, it was the image Katie had tried to plant in his head. She just hadn't expected him to take to it so easily. Time to distract him. "Are we dating?"

Will winced at that, "I... I do want to take you out, Katie. Take us into the city where no one is going to notice and show you a romantic night out... But... It just isn't practical right now."

Katie sat up with a loud splash of water, "Oh, I am so stupid. Will. Have you been worried about cash? Is that why we're always running out of food?"

"We'll get by." He was non-commital.

"Moron!" She yelled and kissed him quickly, "My sweet, fucking, moron. I didn't even think about it. You should have brought up finances earlier. We don't need to just get by."

"Huh?"

Katie flicked him in the forehead, "I do TV sponsorship, idiot. I've got my own finances to add to the pot. The magazine shoot I'm doing tomorrow? I'm getting ten grand for it. I can help you pay the rent."

He didn't actually seem to like the idea, almost like she was intruding on his masculine need to take care of her.

"I'm not going to be your sugar mamma. If that's the problem." Katie said slowly, "But we should go halfsies. On everything."

"You eat more than half the food."

She stuck out her tongue at him, and relaxed as he sucked it into his mouth. Her naked in the bath, glistening and dripping skin. Him in his drenched t-shirt, hands at her back, holding her tightly.

Her hands travelled downwards to tug at his clothes. Which he completely misread. The kiss became hysterical laughter as he climbed into the bath, fully clothed, atop of her.

"Phone." She giggled breathlessly.

Will kissed at her neck, lost in the sight of her, "Think I'd be stupid enough to walk into a bathroom with you if I had any electronics on me?"

"Fair." Katie giggled, "Now, take that damn top off. I want my touch already. My skin on yours."

He tugged the soaked material off with difficult, and knelt down, looping an arm behind her back as he crushed her chest into his and then he... Stopped. Just half-lay there, content.

He took a moment, whilst she tried to figure out what he was thinking and then spoke quietly, "I want to date you, Katie. Ends aren't meeting, but I want a proper date. Not a wet and cold forest."

She thought about her schedule, and training. Her coach was pushing her brutally hard right now, but taking a day before the match to relax and de-stress was a habit.

"Wanna do what I was going to do before I got dumped?"

Will leaned up slowly, "Have sex? Uhm... I wouldn't say no, but I thought we were talking."

"Idiot." She laughed at him, a hand reaching up to run over his flexing chest, "I meant, like, a hotel. Book something for the weekend. Expensive cityscapes, awesome food, comfy bed."

"What's wrong with our bed?"

Katie giggled, "Nothing. It has you in it. But I was thinking five star. I can afford it. Ooh. There's a fantasy I've never had a chance to try before... Think you can buy me a cheap dress? That can be your contribution."

"Why cheap? I can get you something nicer. Maybe." He was hesitant, worried.

She pulled him down to whisper in his ear, "So you can literally rip it off me."

"Oh. Fuck."

Katie cupped at his groin, disappointed to find the water had done what it does and caused him to disappear a little. Didn't stop her massaging at him, "I want you to tear my dress off me. Throw me on a bed. Make housekeeping come knocking to ask us to be quieter."

"That's my dirty little sister." He said lustfully, fully engaged by her imagination.

She shivered excitedly, "I want you to press me up against the window, the two of us looking out at the city, when you fill me up. Make my cunt overflow with your cum, as we see the sunset, together."

"I want to wake you up, the same way. Red light through the window, with your brother's face down between your legs." He said hesitantly, as if confessing to a guilty desire.

Katie's hand on his chest became a claw, "Do you know how long I have wanted to wake up with you actually inside me? I want that, Will. Forget the chivalry or whatever is making you second guess. I want to wake up, half confused, with you balls deep inside me. Can you do that for me, when we go away?"

"Yes." His voice was hoarse.

"Good." She said firmly, and then pushed him off her, "But for now... I think I just want you to fuck me in our nice soft bed."

------------

After they hurriedly towelled off, proceeded in his case by stripping, they basically sprinted to the bedroom. He hadn't gone in expecting or even wanting to have sex with her, but it was now the only thing either of them were thinking about.

He expected he'd need to help her, because of the water drying her out, but the moment he slipped a finger into her, multitasking as he was lowering her onto the bed with his tongue in her mouth, he found that she was practically overflowing all on her own.

Without a thought for foreplay he re-positioned himself and pushed his cock into her sucking depths with a single stroke.

"Oh, fuck, Will."

He kissed at the beautiful girl beneath him on the bed, brushing her hair out of her face, "Tell me what you want. You can have anything you want. I'm all yours, Katie."

"Slow. Do me right, brother. Make love to your sister. Show her how much you love her. Cherish her. Everything she doesn't deserve." She looked up at him, eyes sparkling.

He couldn't help but respond to her, sharing a lingering kiss as he slowly began to draw himself backwards. Feeling her flexing, trying to hold onto him.

He buried himself into her with a grunt, and whispered to her, tucking a hair behind one ear, "There is nothing about you that is undeserving, Katie. I'm the luckiest guy alive."

He could see that she didn't believe him, the quiet sadness in her eyes between her gasps and moans. The loving looks she gave him, feeling spoiled by the pleasure of him throbbing inside her.

"I will always love you." He whispered breathlessly to her, "My perfect girl. So sweet to her jerk of a brother, always there for him. Keeping him outside his head. Making every morning worth waking."

He felt her tightening up like a vice as she focused, showing off some insane kegal control as her stomach pulled in. She went from being surprisingly soft to the touch, to like iron, as she milked him whilst he barely moved inside her.

He was glad she'd asked for romantic and slow, because with these kind of internal movements, there was no way he could risk picking up the pace. Katie was demonstrating a new skill here, and he was not prepared for it.

"Holy... Fuck. Shit." He lost the ability to speak intelligibly.

Katie took on a look of greater concentration and he felt her velvet walls roll around him. His eyes bugged, and his mouth hung open dumbly. Her triumphant smile barely reached his consciousness through the feeling of her fucking him without even moving.

"Come. On. Damn. It." She grunted breathlessly, her grip relaxing momentarily with each word and allowing his brain to jerk a few paces towards a coherent thought.

She was desperately trying to get him off. Herself, and her efforts alone. If she kept it up much longer, she'd get her wish.

And as fucking amazing as it was, this wasn't what she'd asked for.

He fell forwards, pinning her and kissed at her neck, nipping it briefly and distracting her enough for him to take over. He took her ankles and leaned up, placing them on his shoulders, before holding her hips and picking up the pace.

"No... Fair!" Katie gasped out, "Oh, shit, shit, shit, sh-"

It was her turn to lose control of herself, lost in repetition of a single word. Her pussy was overflowing, squelching, as he didn't quite hammer into her, but provided her with something that was sure to push her over the edge.

"This... Is how much... I... Love you." He managed to get the words in, leaning forwards and finding her surprisingly flexible, able to kiss her momentarily, despite their position. "Cum. Cum for me."

"God fucking shitballs!" Katie said raggedly, "Oh, I love what... You do to me! You're the... The... B-best..."

She failed to finish what she was trying to say as her thighs began to quake with a now familiar feeling. The brutal vice she called a pussy locked onto him as he felt the pulse of her orgasm begin to roll through her.

He looped an arm under her as her legs dropped from his shoulders, and her back arched into the air as she cried out loudly.

He had been trying hard to hold on, so that he'd be able to continue slow fucking her to heaven afterwards. The sexy sound splitting the air, whilst he stared down at her as she rocked into him was too much.

"Oh god, I'm... Going to..."

"Inside me." Katie said quickly, "Fill me up, Will. Fill your -"

He didn't make it all the way through her tirade. He saw her feel it, feel his seed splashing into the depths of her pussy.

He saw her eyes sparkle with lustful abandon, the excitement he saw in her eye every time she wanted to do something with him. He also saw something deeper than just desire there. Something that seemed to acknowledge that the sex was only where they began.

Two people, as close to touching the divine as they could be, intertwined with one another. Trying to occupy the same space, to become one.

He collapsed onto her, not pulling out. He ran a hand through her hair and gazed at her exhausted and satisfied face. "I meant what I said. Everything about you... You're perfect. What makes you think you're... Undeserving?"

"Oh, don't do that. I'm not depressed." Katie rolled her eyes, "I know I'm, straight-up, the best little sister in the world. I don't hate myself. I just think that you're better than me."

"God damn, you are." He grinned and kissed her neck, flexing gently inside her.

Katie gasped, "Holy fuck! You're not done?"

"No, I'm done." He said quickly, "Sensitive and exhausted. Just enough left to play for a bit. Sheesh. I'm not a superhero."

"Nah." She shook her head, "Nobody would ever mistake you for a superhero. A damn good boyfriend, on the other hand... Maybe. Sometimes."

"I don't deserve you." He touched his nose to hers, "I have no idea how this managed to happen. And I know I'm going to ruin it. But I will do my best to be at least half of what you think of me."

Katie glared at him, "Already forgot? I crawled into bed with you and fucked you."

He laughed and kissed her neck, "Because you're the best little sister in the world."

"Damn straight. Uhm... This was romantic. But this little sister needs to..."

He rolled off the top of her, "Message received."

"Oh, gross! I'm leaking everywhere! How much did you cum? Fuck, Will." She exclaimed the moment he moved. She staggered upright to begin the awkward waddle, only pausing to look back at him, "Still my favourite, though. You, running down my leg."

He lay on his back on the bed, feeling out of breath and spent, but reeling from the revelation that Katie thought she was the one who didn't deserve him, instead of vice versa.

A head poked around the doorway, "Oi. Jerk. You joining me in the shower to help clean up your mess, or what?"

He immediately launched uncertainly to his feet at the invitation, as Katie giggled and ran back towards the bathroom.

------------

Getting finger-fucked by her brother whilst he pressed up against her back and pushed her into the cold tiles beneath the hot water was one of Katie's favourite things.

The first time she'd invited him to join her, she hadn't expected anything much. Mostly laughter, soap and alternating freezing cold and boiling hot as they fought for the water.

Instead, he'd angled the shower at the wall and pushed her into it. His semi pressing into her asscrack, as his fingers crept down along her stomach to her overly sensitive clit.

It was one of the first times he'd taken over, and one of the few times she could expect him to. Made her feel safe in his arms as he did something for her that was solely and only about her.

It was selfish of her to accept it, without ever doing anything for him in return... But she wanted this to be that. The special thing he did for her, because he loved her.

It made her feel... Safe.

Which was the last coherent thought she got for a while as he found the right spot, and made her cum. She was loud, crying out over and over as he continued to work her. Continued to make her cum. Over and again.

It was too much to physically handle. Her muscles had been torn up from endurance training, as she tried to work off her holidays and Will's cooking. Then the both had been kind, but made her realise how tired they were.

On top of all of that, they'd had sex... And now he was treating her system to the wracking waves of orgasm after body-clenching orgasm.

Katie felt herself nearing her limits, "T... Too... Much..."

Even after her legs stopped shaking and straight up collapsed he simply caught her. He helped her down safely, lying back against him in the shower, and continued to demonstrate his freaking magic between her legs.

Her cries became pathetic and tired little moans as he seemed to suck the life out of her. Coaxing pleasure out of her, like he was filling her with a blinding light. She didn't know how he was doing it. "I... Can't... Can't..."

The light at the end of the tunnel neared.

"One more. One more for your brother." He begged her, pleading with her against what was left of her brain.

Katie stared at him in terror, "N... No... I..."

It was difficult to argue with him when he was knuckle deep inside her. It was utterly impossible when she also found his tongue inside her mouth.

"Oh, fuck it." She mumbled, accepting her fate. She could feel the orgasm building, pushing her up a mountain that no one was supposed to climb. Feel her entire body trembling as she approached the moment. "M-make me cum."

She wanted it. She could feel her soaking his fingers as they played along the inside edges of a pussy that she wanted to be his, and no one else's. She wanted him to stake his claim over her.

More than that, she wanted to cum again, knowing that it was her brother that had pushed her to new heights. Taught her pleasure that mere mortals weren't supposed to know.

"F... Ugh..."

Darkness closed in at the edge of her vision, exhausted and burning muscles tightened, and she tasted copper. This was a terrible idea, but it still felt...

------------

"Oh, thank god, she's awake." Will said into the phone, and the nurse on the line breathed a sigh of relief.

The girl on the couch rolled over tiredly, and spoke with a slur, "Tongue swolven. What...? I fweel hungover."

"Just make sure to keep her well hydrated and check in again if anything seems off." The nurse followed her script, and he thanked her and ended the call.

Will placed a cold glass, and a pitcher, of water on the table in front of the confused and exhausted woman. With not a small amount of guilt.

"Who...?" Katie asked blearily.

His heart leapt into a throat, "Oh shit. How badly did I break you? Amnesia?"

"Moron." She replied and sipped at the water, "We got any painkillers? My head sucks. Who was on the phone?"

He went through his cupboards and found a couple pills and popped them for her, "Nurse on call. Next step was emergency."

"Huh?"

He handed them to her, "You... Passed out."

"No shit." Katie replied and took them, "Did... Will, we really need to talk about your listening skills."

He cringed, "Sorry."

"It was fucking amazing. I agreed to it because it felt amazing. I'm not one for pain." Katie said with half a smile, and then held her temples, "But totally not worth it. Ow. Uh... What time is it?"

"About eleven."

She lay back on the couch, "If you don't mind, the bedroom is too far. I'm going to sleep here. Wake me up at eight so I'm not late? Tomorrow's the photoshoot. It's important."

"Eleven in the morning."

Katie stared up at him, "Oh, shit! I'm way late!"

"Already talked to your manager. He doesn't expect you today, or tomorrow for that matter. Lie on the couch. I'll get you a blanket, and remote. You've had a doctor sign off on bed rest." Will said quickly, "You get a day of movies in bed. Okay?"

She half-smiled through her exhausted haze at him, "What did you tell Dan? That you tried fucking me to death?"

"I'm sorry."

Katie took on a look of concern, "You did?"

"What? No. No, I just said you fainted in the shower. Doctor wasn't that worried, just heat stroke." He shook his head, "Ugh... I'm sorry, Katie. Really. I... I did this."

She laughed weakly, "Yeah, yeah. Don't get so big for your breeches or I'll wedgie you with them. Not the first time this has happened."

Will stared at her, not comprehending, "What? That seems like something I need to take you to the hospital for."

"Idiot." She mumbled, "I... I spent all day training my ass off. Running until I threw up. Then you had to go and fuck me stupid. I just burned out, badly. It really was just heatstroke."

"It's happened before?"

"Yeah. Didn't eat all day, and being young and stupid... Someone wanted to see how many times they could get me to... You know." She said in embarrassment.

Will frowned, "Since we started dating you've never had a problem talking about sex. Or saying cum. There's something else about this story you don't want to tell me."

"I don't like talking about my exes." Katie pouted, and then winced, "Especially with... You. It feels like cheating. I... Regret it. That you weren't my first. First and last."

"Suzie wasn't bad for your first. Kinda impressive you managed to get one of the hottest girls around." He teased her lightly, and then frowned at her face, "Wait. That's when it happened? Suzie ate out my sister so much she literally passed out from exhaustion?"

Katie glared at him, "Yes. And no, you don't get to laugh about it. Ever. It was... Special? I don't like admitting it. Just... Listen to me, in future. I know my limits.""Getting the blanket to tuck in my brilliant and understanding girlfriend." He stated, trying to pretend that he wasn't still being eaten alive by the guilt of it.

"Okay." Katie said mopingly, and then asked timidly, "Can I also have snacks?"

Right now, she could have anything in the world that she wanted.

He fetched their blanket from the floor beside the bed where it had been tossed, and the obligatory stuffed animal that every girl had to own, before returning to the lounge.

Will tucked the rabbit into her arms, before spreading the blanket over the top of her. He kissed her forehead, and Katie made a faux-whimper, looking at him pleadingly.

He sat down in front of her, "What's up?"

"You didn't kiss me. Properly."

He winced, "Katie. I hurt you."

"Hurting me more by avoiding me." She said with a pathetic look, "I'm sick. Can't you just give me what I want?"

Will gave a deadpan expression, "Isn't that half the reason we're here?"

"No fair." She pouted, "You're supposed to give in. I'm your adorable little sister that you nearly fucked to death. You're not meant to have stubborn big brother willpower right now."

He kissed her, almost as hesitant as their first kiss, but there was no literal thunder to underscore this moment. "I don't think that me, and willpower, arrive in the same sentence as you. Ever."

"I know. I love it." Katie grinned broadly, dropping the act. "Just milking it to see how long until you break. So... Snacks? And put on the pirate movie we used to watch as kids?"

He shook his head at how quickly she seemed to make his head spin. He was capable of feeling the full spectrum of emotions every time she opened her mouth.

"The one with the puppets? Or tentacles?"

"Tentacles. Don't think I'm quite done screaming for today." She said without a hint of sarcasm.

The movie was one that came from Katie's horror phase. Some claymation thing that managed to still be terrifying today despite the laughable animation. It also didn't even feature a pirate, but somehow that was what they'd called it when they were kids and way too young to be watching it.

He didn't remember why.

It was so old that finding a copy today was next to impossible, but he kept a copy around just for her. Something they used to pull out around Christmas time.

He sent the stream from his computer to the TV, tucked the remote into her hands along with the rabbit, and then moved into the kitchen to find snacks, before quickly giving up and grabbing his car keys.

"I won't be long. You going to be okay? Got any specific requests?"

Katie pouted, obviously torn between wanting her comfort food and not wanting to be alone. At length she shrugged, "I dunno. Cookies and milk seem like a bad idea on my stomach right now. How do you not have a giant stash of snacks?"

"Because my girlfriend has a thing for giant stashes of snacks and thinks I don't notice when she sneaks them at midnight."

Katie shrugged, "Not really sneaking. Just trying not to wake you up. If you expect me to feel guilty for eating all your food... We might have a problem."

"Nope." Will shook his head, "I grew up in the same house as you, remember? I know that you can eat. Especially when you're stressed out about something."

She didn't miss his hint. "It's just... Lying to people. I just wish I could come out and tell everyone about us. I want people to be happy for me, but... They'd probably put me in therapy."

"Yeah." There wasn't much he could say about that.

Katie bit her lip, but Will didn't push and she didn't say anything else. So he left to go buy her snacks.

------------

Exhausted was an understatement, but Katie had been through a few fainting spells in the past. She'd had tests, of course, but it wasn't a concern. She just had a habit of pushing her body to its limits and not paying attention when it was too far.

A couple times she'd passed out at the end of a match. A couple more she'd been exhausted before she tried to show her partner a good time. Same idea, really.

She wasn't surprised she'd overslept following it.

Remembering the first time she'd blacked out, though, and having it come up more than once recently, was enough for Katie to give up hesitating and trying to work out if she really wanted to do something and just do it.

She picked up her phone, knowing that Will was probably going to be pissed she was doing it without talking to him, and called Suzie.

Her friend groggily answered the phone, "Huh? Uh... This is Susan."

"Suze, it's Katie. You still in bed?"

"Kinda." Suzie noisily shifted in bed, "And alone, apparently. Aw. So harsh, I was hoping."

Katie laughed at that, "Suzie. Benders do not get boyfriends."

"Yeah, yeah. Stop criticising. Do you really blame me? You had to go and bring up that crap about Will yesterday."

She winced, feeling her stomach go queasy and her hands sweat, "I... Uh... I wanted to... Talk about that."

"Seriously?" Suzie sounded annoyed, "Yes. I like him. No, I'm not going to date him. I'm sorry I pissed you off by trying, just once!"

"Can you come over? To Will's place?" Katie felt her throat tighten. "I want to talk about it. With both of you."

"Don't go getting my hopes up."

Katie winced, "I won't be. Seriously, don't... Don't expect anything like that."

"You going to tell me what this is about?"

She shivered, "Uh... No. Not anywhere I can't lock the door to stop you from fleeing. I think the conversation will be good, at the end. But you're going to think I'm insane to bring it up. Please?"

"You suck." Suzie shot back and then made an annoyed sound, "Eugh, fine. I've got nothing better to do. You're a hard girl to be friends with sometimes, Katie."

"If it's any consolation, Will is also going to freak when I start talking."

"Yeah, nope."

------------

Will fumbled the grocery bags as he came through the door, "Got some other stuff whilst I was out, and popcorn and..."

He trailed off as he noticed the mood of the room.

"Suzie's here. Why does everyone look like something died? Is it me? Am I a dead man?"

Katie swallowed, "Both of you have to promise not to run."

"What... Is..." Will trailed off as he saw the serious look in her eye and felt like he was about to have a heart attack. She always was impulsive and usually he'd loved it. Recently, at least.

This time, he felt weak at the knees.

"She'll kill me. Or both of us."

Katie grimaced, "Plenty for her, as well, Will. So shut up, and for once in your life keep your fucking mouth shut."

He left the bags by the door and walked over, carefully sitting in the only space available to him, right next to Katie on the couch. Right in the middle of the discomfort zone.

Katie ran a hand through her hair, "I'm doing this. I'm doing this... We're going to start with an admission I made to Will. That you were my first, Suzie."

The brunette blushed, "Oh. That. Yeah..."

"I didn't tell him everything."

Suzie laughed nervously, "Obviously."

"But I want to."

Suzie's face became one of horror. Will didn't get it, but he'd royally screwed up Katie's plans the last time he casually said anything. If she wanted him quiet, he needed to be.

"You're shitting me. Why the fuck...?" Suzie asked, "Katie. This is a bad idea."

Katie shook her head, "It'll make sense. And clear up some awkwardness. Please. Trust me on this."

"Can I leave first? You don't need me for this."

Katie snapped at her friend, "Yes, I do! Shuddup. Sorry. I'm nervous. Will knows that you were sort of my eighteenth birthday present. And that it was the first time I did something with anyone. But he doesn't know why."

"Why?" Will couldn't help himself, "Figured there might have already been something. Sexual tension. Maybe even a kiss or two."

Suzie shook her head, face grim.

"I was in my room, alone, balling my eyes out."

Will looked at his sister in concern, "You were crying on your birthday? I... Don't remember that."

"It was because of you." Katie stated, "You don't remember any of it, probably. But that was the party where you hooked up with Cassie."

"Oh." It was starting to make sense to him.

Suzie winced, "You're really going to tell him... Everything?"

"I was crying... Because I had this stupid fantasy. Something I knew couldn't happen. Not ever." Katie breathed raggedly, "Suzie found me. You were too distracted with someone's tongue down your throat to notice the birthday girl run off."

Cassie had been more hands on than just that, from Will's memory. This didn't seem like the time to bring up that he had been in the garage getting head whilst his sister was in tears, though.

"You really are." Suzie ducked behind her own knees.

Katie looked at her hands, "It was... Impossible. Always. But you hooking up made me really realise it. I... Had a crush on you, Will. And I wanted you to be my first. On my eighteenth."

"Fuck." Suzie swore quietly.

Will's hand found Katie's and squeezed gently, "You must have hated me."

She smiled weakly, eyes on Suzie. "Anyway... She found me. And I spilled the whole stupid mess to Suzie. She offered me a... Compromise."

"Let the man take it in, first!" Suzie exclaimed, and then became confused when she noticed that he wasn't actually spiralling from the admission.

Katie shrugged, "Suzie would give me an eighteenth to remember. I'd still lose something on my birthday, it would still be special. But I'd still have my actual first waiting."

"That... Is really sweet." Will said to Suzie, "And... Surprisingly understanding. She did kinda tell you she wanted to fuck her brother... Who had asked you out a few times."

Suzie frowned, "...Yeah. Not like it was news to me, though. She banned me from dating you, and it wasn't in an overprotective little sister way... What the fuck is this, Katie?"

"I told her I had a crush on her. That it was the reason I moved out. To get away from her." Will admitted.

The girl cocked her head, "Is that what happened on the camping trip? You two finally get over your awkward repressed feelings to help each other out? Like get her the hell away from your parents?"

"Sorta, yeah." Will replied.

Katie crushed his hand in her grip, "He's being polite. Because he's as scared as I am. You still like Will, don't you, Suzie?"

"Yes." Suzie groaned, "Yes, I like your brother. The only reason I didn't... Go behind your back... Is because I also like you. Is that what you wanted me to admit? I kind of hate you right now."

"Going to be worse." Katie muttered before taking a deep breath, "I... I didn't tell Will that I used to like him. I teased him about liking me. But... Oh god. I did it, Suzie."

"You two kissed?" Suzie just about exploded, "Wait. Why the fuck are you living together? Doesn't that seem like a super bad idea after you... You didn't just kiss."

Will looked down, ashamed.

Waiting for the rant of judgement, and the threats to bring the world tumbling in on their heads.

Suzie stood up angrily, "Are you two still doing shit? Please, tell me it was a one off. Tell me that you're not fucking your brother, Katie!"

"I love him." She mumbled, right on the edge of tears. "I just... I hoped..."

"Hoped what, that I'd understand?" Suzie said, perplexed, "You were supposed to grow out of that! Supposed to realise I would have made any excuse to have you to myself."

Will's head jerked up as he heard her voice cracking. He hadn't expected that one, even after hearing that the two of them had been together for a while.

He'd sort of expected it was some friends-with-benefits type situation, which made him kind of an asshole. He'd failed to realise that the two of them had probably been intensely romantic.

Except, Katie had been using Suzie to get over him.

And Suzie had been in love with Katie.

And... And maybe him...?

He was confused, now.

"Suzie." Katie said desperately. "Please."

"I... I can't even..." The girl kicked the table, "Fuck's sake! Will. You're too stupid a shit to lie to me. Do you think you actually love Katie? That this isn't some stupid sexual thing?"

"Yes." He didn't hesitate. His heart might be in his throat, he might be terrified of what was about to happen, but he knew one thing. "I love her."

"Ah, fuck." Suzie deflated, "I am not okay with knowing this, Katie. I'm really not. I'm not going to break you up, but you're both fucking stupid. There is no possible way this ends well."

Katie winced, looking up at her, "I... Wanted to say sorry. For keeping him away from you. Stealing him. I knew you liked him, and I... Wrecked every chance I could. I'm a terrible friend."

"Yes, you are!" Suzie yelled, and scratched at her head, "God, fucking damn it. The two of you. Seriously. An item? What is it? Dating? What are you going to do? You can't get married. Really can't have kids."

Katie shrugged, "You know me."

"You haven't even thought about it." Suzie glowered, "Oi. Shitheel. You always spiral. What do you think is going to happen? What if Katie actually gets famous. Everyone is watching. What then?"

Will winced, "I spiral. Doesn't mean I have answers. Right now, having what we have is enough. I don't have any answers. And yes, it is stressing me out. But I'm not giving this up willingly."

The woman paced back and forth, and then turned, "Are you just pretending to sleep on the couch, Katie? Keeping up appearances?"

"No." She went red, "Actually... Eh... I may have passed out in the shower. Usually I'm sleeping in the bed. With Will."

"Too much information. I'm already jealous and angry with the both of you." Suzie snapped, "Even ignoring the fact you two definitely should not be dating... I am the last person you should be talking to. I like you both. Sort of an asshole move to tell me."

"Will didn't know I was going to." Katie insisted, "If you have to be mad, be mad at me. I'm the one who crawled into bed with him. I'm the one who kissed him, and I'm the one who told him to fuck me."

"I'm mad at both of you!" Suzie shouted.

Katie's head fell, and Will squeezed her hand. He resisted reaching around and hugging her, knowing that would end in tears and Suzie leaving to cool off. "I think... I think Katie wants to know if this is it. That you're just going to hate her now, or if she has someone she might... One day... Be able to talk to."

"This is so fucked up." Suzie rubbed at her head, and then walked over and dropped back into the chair, "Will, if you ever hurt this girl, I am coming for you. And I will be coming with a big ass knife and I will literally feed your balls to you before I kill you. I am not exaggerating."

"Fair." He replied, barely breathing.

Katie sniffled, "Does that mean... You might... Forgive me? One day?"

"No, it means I'll never forgive Will if he fucks this fucking fucked up fuckshit." Suzie cursed, unable to find the words. "Right now... I don't know what I feel. I don't know if I hate you Katie, because I... Don't even know if I'm awake. This is going to take some time."

Katie nodded silently, "Can... Can I hug him? Hide?"

Suzie rolled her jaw, and shrugged, "Fine. I already know stuff. There's no real point hiding any of it now."

The girl shoved her face into Will's chest, and crawled into his lap before grabbing the blanket and yanking it up over her. The sound of frightened tears emerged from the bundle, as he gently put his arms around it and began to rub her back.

All the while, acutely aware that Suzie was staring death daggers at him.

He had not a clue why Katie had decided the moment to do this was now, right after she'd been sick and a few days before they had planned to have their dating getaway to the city.

She never really did think through her moment. She just reacted. If she decided she wanted something, then she immediately felt the need to follow through with it.

He could really have used a heads up that she was going to call Suzie over and just explain... Everything.

"Well. Not the way I expected this to go after I told Katie that you and I did not sleep with each other." Will said, not knowing what to say in this awkward space.

Suzie rolled her eyes, "Yeah. Opportunity fucking missed."

"Do I get to ask... What happened? Or is death still on the table?"

The woman laughed bitterly, "Ah, what the hell. You're too stupid to figure it out on your own. I burst into tears because I felt like I was cheating on Katie. Even though we'd broken up and she made it clear she wanted guys. Specifically, you. But guys."

"So you like her more than me."

Suzie laughed, "Wow. That's your takeaway? You're still an idiot, Will. I was upset because I couldn't choose, and I wanted to. And my life was shit. And I felt like I was about to fuck it all up, worse."

"For what it is worth, Katie teases me about liking you."

"Do not say that." Suzie glared at him, "Not right after admitting you are fucking your sister."

A timid head looked up at him from inside the blanket, "You're not completely stupid."

"Only mostly. But you have been dropping so many hints." Will shrugged, "Still not sure. And now is not the time."

The brunette frowned, "What the fuck are you two gossiping about? Katie. Don't make me drag it out of you."

"We're going away." Katie said, turning around and emerging from the blanket, but staying in his lap and arms. "Before my upcoming match."

"You're eloping?"

"What? No." Katie shook her head, "I still want my tennis career, Suzie. I'm not giving up my life for him. I'm sharing it. We're just going somewhere people don't know us, so we can... Do stuff. Romantic stuff. And yes, sex stuff, too. Fantasies."

"Don't want to know."

Katie smiled coyly, "Yeah, you do. You're just mad at me. But... You've got as many problems talking about sex as I do. And you're really dying to ask me how good Will was, but don't want to seem like you approve."

"I am mad at you." Suzie admitted to part of it.

Will decided to step in, "Why don't we take this slow, then? Katie is a damned dream, isn't she? That cat arch thing she does. When she... Does."

"Will. Don't." Suzie said, going bright red and clearly remembering it.

He laughed at her, "Just about breaks my neck. No idea how you managed it over time. But you always were more fit than I am."

"Oh for... You two aren't going to let me leave until I admit that it's a turn-on, are you?" Suzie glared at the pair of them, "Fine. I disapprove of you. It also fucking hot and probably going to haunt my dreams. My two crushes, in a forbidden relationship. Yeah. Fucking hot. Fucking wrong."

Katie glanced at Will, asking for permission.

"I did say it isn't the right time, yet."

She glared at him, crossing her arms, but sighed, "Fine. If you really want to take off, Suzie. You can. I just... I hated keeping it from you. Lying to you."

Suzie seemed like she'd remembered something, "You called Will an inconvenient ass and then hung up on me the other day. Do I want to know?"

"I came home, saw her on the phone and..." Will shrugged, "In my defence, she was dressed very sexily."

"A hoodie and panties." Katie said sarcastically, and then shrugged sheepishly, "Yeah. He's not bad with his tongue, so long as he isn't actually speaking."

Suzie stood up, putting a hand up, "Hot. Not today. I'm going home. I will... Just give me time. Don't call me. Don't text me. Give me some space to process this."

"Okay." Katie choked, as her best friend walked away from the both of them and out the door.

Will fell sideways onto the couch, dragging Katie down with him into a tight cuddle. She drew the blanket up over them and re-positioned to bury her head in his chest. "Sorry."

"So, just to be absolutely clear about this, Katie." Will said slowly, "I'm fine with you telling Suzie, now. As to you wanting to turn us into a threesome? I don't know. I don't feel that way about her. And I don't know if she can... Take it. Psychologically speaking. Especially if I don't love her back."

"Thruple." Katie corrected him, "You really don't love her, Will? If you don't, I'll drop it. I thought... You were into her. As much as I am. She's cute and over the top and... You don't?"

"Maybe if I had a chance to date her? Get to know her?" He said cautiously, "She's a pretty face. But that's it. I've never got to know her that well. She's been your friend, and fairly off limits."

Katie looked excited, "So it isn't the thruple thing? You'd be willing to... Share me?"

"No idea." He admitted, "I do get jealous thinking about you and her. But... I'm an idiot. I didn't realise there were actual romantic feelings involved. I didn't realise you loved a girl. Go ahead, call me a biased dick. In my defence, you did tell me you weren't into girls."

Katie flicked him in the forehead, "God, you're annoying! It's just like you don't get to have a one night stand with your sister, asshole. You don't have more than the one night with your best friend. Once is forgivable, if not forgettable. Ongoing means there's something there."

"Sorry."

She snuggled tightly against him, "Eugh. I hate you, sometimes. So fucking stupid. Put on the movie and let me sleep off some of this. Today has sucked."

He reached over to unpause the film.

------------

Katie didn't want to wake up.

She was warm and comfortable. In Will's arms there was nothing in the world that could hurt her, and there was no stress. Her head, on his chest, was the closest thing to absolute peace that there was.

Unfortunately, someone had cursed her with having a bladder.

So, in being forced to leave her brother's arms, she also took the blanket. He moaned tiredly and grasped for it as the cold came in, but she was faster as she ran off giggling with it around her shoulders.

Having had a half decent sleep, Katie had the space for a lot of introspection as she sat on the toilet.

Should have brought her phone to distract her.

On one hand, she had a crazy understanding and sweet boyfriend. He had to be a secret boyfriend, but he was understanding. He had barely reacted, let alone overreacted, to her taking unilateral action and exposing themselves.

Then, on top of that, Katie had dared to ask him to share her with someone else. She couldn't be happy breaking one taboo. She must be an addict to the forbidden.

Still, he stuck by her.

Will was wrong. She didn't deserve him.

Then, on the other hand, she had completely toasted her friendship with Suzie. Fifteen years of going through absolutely everything together down the drain.

If she reached out or made the slightest push, Suzie was going to cut her off. Cut her out of her life, and be done with her.

The worst part was, Katie felt like she deserved it. She'd blocked those two having a relationship for years, but at least if Suzie and Will dated it wouldn't have been some forbidden shit.

She'd stolen her brother, a guy she shouldn't have, away from her best friend.

That didn't seem forgivable.

Katie cried.

Eventually, still sniffling, she emerged from the bathroom to find the couch empty and Will oblivious to everything with his headphones in as he cooked away in the kitchen.

She checked her phone as she cacooned herself onto the couch. No messages or calls, but it looked like she had just slept through to dinnertime.

It might take Suzie weeks.. Or never.

Katie buried her face into the couch and screamed out her frustration at herself for handling everything so badly.

She didn't feel any better.

Thinking hard about it, Will had to have been stressed to high heaven the entire time. He was the one of them that always imagined the very worst possible way that something could go.

Katie smiled slowly and slid out of the blanket, adjusted her clothing slightly, and skipped up behind him. She grabbed him from behind, pressing her bare chest into his back.

Will took his headphones out, "Hey, you."

"Hey." Katie said nervously.

He shrugged, "About to put the pot in the oven. I picked up the stuff to make your favourite when I was out."

"You really are the best big brother." Katie grinned, trying and failing to put a sultry accent on as she did. Trying to hint to the oblivious man.

Will shuffled them backwards, and put the dinner away, and set the timer for forty five minutes. Which would be more than Katie would need to do what she wanted to.

"I mean it Will. Not just because you cook for me. You're the best." Katie mumbled, "I dropped so many bombshells on you today, and you're sticking by me."

He teased her, as he failed to turn, just trying to head for the couch, "You don't get to dump your sister once you fuck her, do you? I'm afraid you're stuck with your idiot brother. Forever."

She tugged on his shirt, stopping him, and he finally turned to see that she was wearing nothing except her panties. "Good. Because you're stuck with me."

"I... Uh..."

Katie grinned, going up on her tippytoes to meet push her tongue into his mouth. She could feel his initial surprise at her response, the idiot.

She slid her hands down his back, gently holding onto his waist as he explored her mouth. Katie could feel her brother struggling to hold back, trying to be romantic with her whilst she set him on fire.

She broke the kiss and nipped at his chin, "I love you."

"Mm. Noticed." He said, breathlessly and a little bit out of things. She adored the way his mind just sort of went blank whenever she put herself on display. Made her feel like a goddess. "You're the best little sister."

Her eyes sparked, "Damn straight I am. So, we're going to do this before we have dinner, because it's spicy. And I'm amazing."

She knelt down on her knees and reached for his belt.

"I wasn't -"

Katie rolled her eyes, "Oh, I know. I'm just the best damn sister in the world. So, I'm going to suck my brother's cock, because he's spoiling me. And because I feel like it. Problem?"

"No." He whispered hoarsely.

His pants came down quickly, whipped down with his underwear. She kissed gently at his semi-hard cock, unable to help herself. She loved watching it jump at her touch.

Loved knowing that every single thing she did could get a reaction out of him.

She leaned in, licking him upwards from the base of his dick until she reached the head and then she engulfed his cock into her mouth. She felt it hardening to its full size as her lips travelled down, her throat bulging as she took the entire length with a focus and zeal.

"Oh, fuck!" Will exclaimed.

Katie's own eyes were almost as wide, surprised that she'd managed to pull it off. She was actually deep throating her brother's cock. That dirty thought was a panty flooder, as she began to show him just how much she appreciated him taking care of her. Putting up with her bullshit.

Her head bobbed up and down slowly, taking her time to draw her slippery tongue along the bottom of the rod in her mouth.

Saliva slurped and dripped from the corner of her mouth as she worked him, making as certain as she could to let Will know that she utterly adored him. That even if it was only them as a couple, she was going to be happy.

As she was noisily bobbing along she felt both his hands grasping onto her head, Will just trying to keep his balance as she succeeded in becoming the only thing in the world he could focus on.

"Oh god, yes. Holy fuck, Katie." He groaned loudly. "Shit, I wanna fuck you."

She pulled off for a brief moment, hand still running up and down him, "Now then, don't get greedy. You can cum in my mouth, for now. We can talk about other stuff once dinner is done."

"Screw dinner." Will complained, but she shrugged and went back to making her suggestion happen.

She swirled her tongue around him and increased her pace, facefucking herself with his cock as she felt him trying to resist and hold on in the hope he'd get something more.

Katie rolled her eyes. As if she'd let him win this one. She shook her head side to side before plunging down and deep throating him again, her nose nuzzling his pubes momentarily before quickly bobbing up and down.

Will lost control, his thighs quaking as he fired off like a canon into her mouth. She gagged in surprise, no warning before he violently flooded her, spilling around the dick still in her mouth.

She pulled back from his still-spurting cock in astonishment, getting sprayed in the face and hair, and drooled in to her hands, coughing weakly as he groaned away.

Will held a hand to his chest as he tried to catch his breath, "Uh... Sorry."

"Holy shit." Katie laughed nervously, "So... I think you needed that. Wow. And now I need the bathroom. Don't worry, won't be long."

Which was when the doorbell went off.

With a giggle, and excitement at the thought, Katie grabbed her t-shirt and slipped it over her head and ran over to the door to check if it was someone she could show off for.

She opened the door in surprise after checking the peephole, "Suze?"

The woman blinked and took a double-take, "You have cum in your hair."

"Girl has to have fun." Katie laughed at the dirtiness of it all, and then her face fell. "Ah, shit. I'm going to go clean up. Will, Suzie wants to talk to you. And not me."

------------

Suzie shook her head as Will scrambled to finish doing up his pants, "Uhm... You okay?"

"After seeing that?" The brunette replied angrily, and then sighed and leaned against a wall, "Not really. I didn't go home. I went for a walk, clear my head. Ended up sitting in the park until the lights came on. Will... First you steal my heart, and then you steal my ex. Don't... Katie said a lot. Don't you have anything to say to me?"

"Can I say anything that wouldn't involve getting threatened?"

She looked at him, hurt, and he realised he'd said the wrong thing. He ran a hand through his hair, "Ah... Fuck it. Stay for dinner. I've cooked enough, so it isn't a problem. We can sit around and laugh, like old times. You can see for yourself if you think I'm going to hurt Katie. I know I'm an asshole. I'm working on it."

She crossed to the couch and tossed the blanket into a corner of the room. Suzie sat cross-legged on it, and looked at him with hurt eyes, "So... You're over me, then."

"I've had a crush on Katie since before I knew what crushes were." Will tried to be diplomatic, sitting on the floor behind the table and leaning on it. "I'd say that right now, we're still figuring out things. What we like and don't like. It's hard for me to notice anyone other than her, and she did sort of blindside me."

"Forget about Katie for two seconds!" Suzie yelled, and then her bottom lip quivered. "I... I came so close to choosing you over her, Will. I've regretted it ever since. And you... You don't feel anything at all for me?"

He shrugged, "I'm not going to cheat on my girlfriend, first. And second, I don't think... I haven't had the space to explore if you're girlfriend material. If we're even compatible."

"You're an asshole, alright." Suzie rubbed at her face as a tear slipped down her cheek, "Here I am, spilling my heart out, and all you can think about is your sister."

"Katie wants to know if I'll share her. What she really wants is the three of us." Will said quietly, "That's... Distracting. My answer to you is also an answer to her."

Suzie smiled sadly, "Yeah. She's not subtle."

"She's also listening." Will glanced towards the cracked open bathroom door, "And terrified that you hate her. So I guess... I'll give you both my answer. I don't know if I'm willing to share her. I love her, Suzie. Too much. But... I think I'd be okay with lending her to you, once in a while. Best I can offer."

Suzie frowned, "You're hearing love, and offering sex. That's a shit deal."

"Sorry."

She shook her head, "You're still not hearing me, though. Yes, I do like Katie. And I might take you up on that. God knows I have enough one night stands. But, Will... You. And me. I like you. Not just wanting to fuck you. Is there... Nothing? Not even a spark?"

"If Katie didn't exist, maybe." He shrugged. "But I made a choice. It's harsh. But this isn't something I can be subtle about. Rip off the bandaid. She won."

The tears openly ran down both cheeks of the brunette, making him feel like a complete and utter jerk.

Maybe he should have found a better way to phrase it.

Katie opened the door a little more, so that her eyes were visible, "Suze, I know you really fucking hate me right now... But can I make a suggestion? To help change his mind?"

Suzie shot a death glare at the bathroom, "Why would you care?"

"I want you both!" Katie yelled, emerging and stamping her foot. "Maybe I'm just selfish. But I still have feelings for you, Suzie. I have feelings for Will. And I wish that not only could I have you both, that you could have both of us. I never wanted to hurt you. I told you about this, despite the risk. Never asked you to keep it quiet. I trusted you."

Suzie crossed her arms, "What's this idea, then? What's going to convince me to forgive you? Will to see me?"

"Do you remember my other first? With a guy?"

Will glanced between them, "Wait. Suzie was there for that as well? Is there any first you haven't shared?"

"Just you." Suzie whispered.

Katie closed the distance, kneeling beside her friend and taking both her hands, kissing them gently. "I never meant to hurt you. I just saw an impossible dream, and took it. I'm bad like that. Now, I see another, and I want to be selfish. Please."

"You already have him. Stole him." Suzie replied, the angry mask slipping to reveal nothing but pain.

"I did." Katie replied, kissing her hands again, "So I'll be the apology. Will has to watch, and you can do whatever you want to me. Tease me until I can't take it, and then walk away. Make me understand how I hurt you. Make my brother want me. Want you. But unable to do anything about it."

"No."

He felt his sister's heart break from across the room. He saw Katie desperately trying to reach out any way that she could, to try and keep the friendship intact. Even a hollow shell of it.

"Reverse it." Will found himself offering on Katie's behalf.

Suzie glared at him, "What now? I don't think I deserve to be punished, you jerk."

"You think Katie does. And I would do anything for her."

The brunette blinked, "Wait. Are you offering to fuck me? In front of your sister? How does that fix anything, Will?"

"I'm offering myself to you. Fuck me, don't. I don't care." He shrugged, "Make me kiss you, like I would kiss Katie. Pretend that I'm head over heels for you. I will do anything for her. She doesn't want to lose you. If this is what it takes, it's there."

Suzie looked between the desperate couple, and then glared at Will. "Fine. But you're not going to enjoy this. This is all about me, got it?"

"His tongue is amazing." Katie promised on his behalf. "And it shuts him up."

Suzie stood up, "Lie down on the couch, Will. Katie, sit on the table, and take off your panties. You can't touch, but show off. Know that you can't touch yourself, but that you want to."

Will had not expected Suzie to get into this so quickly. Katie clearly knew it, that her friend had a thing for domination. But then, she would.

He, on the other hand, wasn't really sure how he was being punished. He'd crushed on Suzie in high school. He'd very nearly dated her afterwards.

He also had no problems giving cunnilingus, he enjoyed it.

Will did as instructed, lying down on the couch. Suzie took a minute to look Katie over, as she pulled down her pants, "So you two... I walked in on only a blowjob? No sex?"

"I was aiming for after dinner." Katie shrugged, "He'll be sensitive. Still recovering."

"Perfect." Suzie turned around, leaning over Will and looking down at him. He saw determination in her eyes, but the anger seemed to have faded. Replaced with... Well, he was hoping it was lust. And not blood lust. "Katie. Pull down my panties. The way I like it."

Will watched in amazement as his sister leaned forward, sneaking a quick flick to her own clit, before she nosed into Suzie and then slowly drew her panties down to her knees with her teeth.

As Katie returned to her sitting position, she winked at Will.

The brunette took the panties off the rest of the way and then tossed them to the other woman. "Something to sniff when you get jealous."

Then, she stepped awkwardly onto the couch and lowered her pussy onto Will's face. He barely got to see a well-groomed bush before he felt something wet tickle his nose.

He re-positioned his head, and didn't wait to be instructed. Katie was way into this, and the smell was intoxicating. He didn't really feel like this was cheating.

His tongue snaked out, pushing into the open twat above him. He heard Suzie breathe in sharply in surprise. She tasted different to Katie.

His sister was almost sickly sweet, whereas Suzie was more of a musty and quiet sort of taste.

"Oh god, he's thinking." Katie spoke from beside them, "He's comparing us, Suzie. How does it feel? My brother's tongue inside you? Knowing the last cunt he sucked was mine?"

Suzie didn't say anything, but Will felt her stiffening at the vivid words. He took her hips in his hands, steadying her, as he began to focus more on the task at hand.

The brunette's clit was more sensitive than Katie's. He could barely touch it without her instinctively pulling away, making him focus more intently on her dripping region.

Her opening was already spread, but he didn't have a third hand free. So he made a suggestion. "Katie, mind holding her for me? So I can fingerfuck your best friend?"

"Huh?" Suzie said, suddenly realising she was losing control of the situation.

"Better idea." Katie replied, "Lie her down on the couch, Will."

He wrapped his arms around Suzie, flipping her over and downwards so she was on her back, only naked from the waist down. She looked at the both of them in shock.

Katie grinned at Will, and nodded at him to continue eating at the pussy. As he did, she crouched beside Suzie, and he saw her leaning over to kiss her.

He felt a mixture of awe, jealousy, and overwhelming lust. It might have been one of the hottest things he had ever been involved with.

One of Katie's hands crept down, joining Will. His sister inserted her middle finger gently into the cunt, as he continued to lap away at the fluids beginning to run.

Suzie moaned, but the sound was stifled by the tongue that was in her mouth. He felt her flexing back against the both of them.

The girl couldn't complain that this wasn't all about her pleasure.

Katie broke their kiss with a deep breath, "Well. I think it's time you took that top off. What do you think, Will? You take her right breast, I'll take the left?"

"Wait. Too fast." Suzie pushed her back, "Where is this going? Where's the line?"

Katie frowned, "Well, if Will nuts in you I might ignore him for a week. That's mine. But... Apart from that, whatever you want. Opinion, Will?"

"I dunno. Just going with the flow." He shrugged, "As long as I'm not upsetting you, Katie."

"I had you first." She shrugged.

Suzie looked between them as if she'd just realised that she was their prey, and not the predator. She took a nervous swallow, "Uhm... I want to do something. Will, sit up. Katie... You can sit where I was. I... Liked the commentary."

As he sat up, Suzie tossed the remains of her clothes, revealing two beautiful breasts. One was about the same size as Katie's, the other a half size smaller.

Whilst Katie's aureoles were small, Suzie's were larger. Still beautiful, but not cute. Her nipples were also bigger, and hard.

"Pants off, Will." Suzie stated.

Katie leaned back onto the couch as he shuffled out of them, her hand dipping down without guilt as she stuck a finger inside herself with a gentle moan. "Do what she says, Will. Do whatever she wants, my dirty brother."

His dick had sprung to life, still glistening from the mess he had made earlier.

Suzie grabbed either side of him as she crouched over the couch again. This time lowering herself deliberately towards his cock, instead of his mouth.

"Ooh, Will." Katie cooed, "You're going to fuck her. You're going to fuck my best friend in front of me. Stick that dick in her warm cunt."

The woman moaned as she felt his head at her entrance, her velvet channel wrapping tightly around him. Suzie sat down slowly, ever so slowly, before grunting as he bottomed out inside her.

Her face was bright red as she looked into his eye, breathing hard. "Holy. Fuck. I... I've never..."

"Never been so full, right?" Katie said excitedly, "He doesn't look it, but goddamn does it feel good. So much better than fantasising about it. Go ahead, Suzie. Fuck him. Fuck my boyfriend, whilst I watch."

Will felt her tighten as she tensed up, before lifting ever so slightly, before slamming down again. He groaned quietly, still staring into her determined eyes.

Suzie smiled at the reaction, and did it again.

From this position, he couldn't really rise up towards her. She was in complete control, just like she wanted. What he could do, was brush the hair over her shoulder, before kissing at her neck.

Suzie moaned and pushed into the touch.

"That's it. Fuck him. Ride his hard cock, Suzie. Let him know what he's been missing out on."

The two of them responded to the dirty commentary. He moaned, and Suzie began to find her rhythm. His sister continued to spill on about the two of them fucking in front of her.

"Don't you love the way he flexes? The way he looks at you like fire." Katie said jealously, "Kiss him, Suzie. Stick your tongue down his throat."

He felt Suzie's tongue across the tops of his teeth, her lips locked on his as she continued to slowly drag upwards against his cock before slamming it down hard. Burying him up to the hilt.

He could feel her juices flowing, down the length of him, before spilling free. Overflowing as she rode him, squelching loudly with each deliberate movement.

"Will." Katie whispered quietly, trying to get his attention despite the kiss. Eyes opening, he saw his sister standing behind Suzie, using her hands to signal to him what she wanted him to do.

He grinned and spun them around on the couch before Suzie had a chance to realise he was turning the tables on her. She gasped as he slipped free, ending up on her hands and knees, braced against the back of the couch.

He distracted Suzie, his cock sliding straight back into her slick folds, as Katie gleefully climbed up onto the back of the couch, legs spread.

Positioned so that as Will rammed himself into the surprised woman, she face planted into his sister's exposed cunt.

"Mmm." Katie said with satisfaction. "That's it, Will. Fuck her as she eats my dripping snatch. Tell me. What's she like, Will? How do we compare?"

His hands were fixed on Suzie's hips, her hands planted firmly against the couch as he drove into her. She was quieter than Katie, but he still managed to elicit a series of moans with every thrust.

He could feel what she liked, see her head hanging when he sped up, pushing to a desperate tempo he knew he wouldn't be able to maintain, especially not if he followed through with his sister's suggestion.

He half collapsed onto her back, catching his breath, "Goddamn. So wet. Not quite as tight as you, but still... Fuck. She's amazing."

"She's a fountain." Katie smiled knowingly, "How's it feel, Suzie? Will finally fucking you. Your best friend watching. Approving."

The woman barely managed a moan, unable to really talk unless he was going to stop moving altogether, and he wasn't interested in that.

"Do what she wanted, Will. Say it, just like she wants."

He kept his eyes on his girlfriend as he leaned forward, whispering the words into Suzie's ear, meaning them for Katie. "I love you."

"Ugh!" Suzie grunted, tensing up and pulsing as she came, "Fuuuck!"

Katie's face became panicked, as she saw him and knew the warning signs by now. "Oh, no you don't. That's mine."

She dropped down the couch, underneath the struggling Suzie to arrive at the edge. With a herculean effort Will withdrew from the still-pulsing brunette before pile-driving himself downwards into Katie's moistness.

She was hotter than Suzie, he could feel differences in their shape, subtleties to the way they moved. And that was about as far as his mind got before he found himself grunting loudly, and spraying burst after burst.

Suzie's knees shook, and she collapsed onto Katie, giving him the view of both the gorgeous women as he continued to fill up his little sister. His cum in his Katie's hair. Sweat beginning to appear on Suzie's back. Both of them flushed red.

He slipped out from Katie, his still-hard cock drawing up against the outside of Suzie's folds on the way passed, causing her to give a pained moan into Katie's shoulder.

He stumbled backwards until he had a space where he could fall backwards, staring up at the ceiling. "I... Can't believe that just happened."

"Fuck." Suzie agreed.

Katie giggled, and he heard her kissing her friend excitedly, getting the best of both worlds. He didn't actually mind. Not after what they had just shared.

He leaned up on his elbows in time to see a glob of his seed slip free from Katie and fall to the ground. "So, are we... Okay? Suzie?"

The woman broke the kiss and sat up on the couch, sweat on her red face, "You don't play fair. You two are as bad as each other."

"I know. Isn't he the best?" Katie laughed.

Suzie glared down at her, "This does not mean I'm moving in. Or that I don't think this whole thing is weird. But... Maybe I forgive you."

"Will... About that hotel room..."

He frowned, not entirely comfortable with the way things had changed. He felt like he was sort of using Suzie. With permission, but using. "I'm dating you. Not her."

Suzie nodded, surprising him as she agreed, "Yeah. Lets keep this as a thing. I'm not saying no, and I'll be happy to be fucked by either of you whenever you want it, but... Let's just see where this goes. No promises we'll regret later. Casual."

"Aw." Katie said in disappointment, "And here I was hoping that Suzie could wake me up, and then when I go for my run Will could take over."

"Maybe one day, you horny git." Suzie snorted.

Will shrugged, "You both seem into this. So why don't we have our weekend away, Katie. Then... Maybe we have a party for the three of us after you win your match."

"I don't think I'm going to win, Will." Katie screwed up her face, "That's half the stress."

"How about this?" Suzie said slyly, "If you win, I'll stay over and Will takes the couch. If you lose, I'll take the couch and you two get the bed. Make it a bet."

He doubted that in either scenario it would end that way.

However, it gave Katie a goal to shoot for.

"No offence, Suzie. But if I win, Will is definitely going to be in my bed. Not having you sneak out to screw him." Katie laughed knowingly.

The oven's timer went off.

"Still staying for dinner?" Will asked.

Katie grinned, "I mean, afterwards, you could help me fuck him some more."

"Sheesh. Your appetite is insane." Suzie complained, and then she smiled, "Maybe. We'll see."
