ONE ROOM TOO FEW

All my problems started when my older sister, Rachel, went away to college. Mom decided that her and I no longer needed our three-bedroom house and she decided to move to a smaller condo in town to save money. The condo wasn't nearly as nice as our house had been. All the bedrooms were smaller, there were two very small bathrooms and the largest problem that Mom didn't even seem to think about until Rachel came home for winter break, there were only two bedrooms. When we first moved there, Rachel had left for her first semester of college and I was about to start my senior year of high school, having turned 18 at the start of the school year.

The problems started the week Rachel came home and I had to move my stuff off of her bed and dresser. On my half of the room we "shared", there wasn't enough room for my PlayStation, TV, clothes and school stuff. Whatever... Rachel will be gone in a few weeks and everything can go back to normal. I thought as I moved my stuff and my useless sister just watched when she could be bothered looking up from her phone.

As the time Rachel was home dragged on, I noticed something, the two of us were getting along much better than we had living together full time. We would make conversation on our respective beds. I asked her what college life was like and she gave me honest answers, telling me about dorm life, activities and her classes. She would ask me about her old teachers and my plans for college. I had applied to a few schools, including the one she went to, all in hopes of getting a good enough scholarship to go away.

One week before Christmas, I started my winter break and finally could spend some time relaxing and working. I greet Rachel as I walk into the room and toss my back pack on the floor next to my bed. My sister smiles up at me, "How was school?" She asks, generally sounding interested.

I look at her before answering. Rachel has a pretty face with elvish features. She has long, straight black hair that goes midway down her back. She is about 5' 6" and has a pretty nice body. Probably C-cup breasts, a nice ass, a toned stomach and legs that drive a man crazy, complete with a thigh gap that is just barely there. "It was okay. Same shit as usual." I answer, flopping down on my bed.

"Well that's good I guess. Happy to finally be on break?" She asks.

"Yeah. It's nice to have some time to just relax and not worry about grades or anything." I reply, turning my TV on, ready to start break right. The two of us make small talk for the next several hours, taking turns asking and answering questions and generally enjoying our time together.

The next morning, I go to work, dressing in my uniform and preparing for a long and tedious day of helping people find the tools they are looking for, find the right size screw or nail and just hoping my shift goes by quickly. I get to work and begin my job, talking to my manager quickly. It is an incredibly slow day that just seems to drag on. Finally, around lunch, my boss tells me to just go home.

Nice. Maybe I'll go home and take a nap or something. Maybe go see that new movie with some friends. I think getting into my car and reaching home a short time later. I walk inside and slowly make my way upstairs, paying attention to my phone. Stopping outside the door to the room Rachel and I share to look up. The door is open slightly and from inside the room, I hear soft moans. What the fuck is that? I ask myself, taking a quick peek.

What I see almost causes my jaw to drop. Inside I see my sister, legs spread wide with both her hands holding a dildo that she plunges in and out from between her legs. It takes me a second to process what I'm seeing. Is Rachel... masturbating? That would explain the moans... I think, running through my list of options. While I'm deciding what to do, my hand pulls up my phone and I snap a picture. As I do I think, what's wrong with me? Before I can delete the picture, I feel my cock grow hard from the sight and sounds of my sister working her pussy. How fucked up am I? I wonder, watching my sister fuck herself with a dildo.

Almost as if hearing me, Rachel stops for a second before going right back to playing with herself. My sister's actions cause a bolt of panic to shoot through me. Did she see me? No... if she did she would have said something. I begin to feel slightly worried that she might have seen me and begin to think about what to do next.

I creep back downstairs, my sister's moans becoming quieter as I move away. I head into the kitchen and quietly get out a glass for water. I stand in the kitchen and look out the window at the parking lot before I slide my phone out of my pocket. My hand trembling, I open the photo's app and open the most recent picture. I look at it for a second, eyes memorizing the details of my sister's wonderful legs. I wonder how it feels to be between them...

I try to fight off the erection I begin to bet from imagining what my sister's pussy is like. I stand silently in the kitchen, debating whether or not to delete the picture. Finally, about 10 more minutes, I hear the shower turn on. I close the app and make my way upstairs to the room we share. Rachel's sheets are all wrinkled and messy from her "activities" and the room smells like pussy and cum.

I try to ignore my erection as I lay on my bed and begin to play video games, trying to get my mind off of what I just saw. A short time later, Rachel come back into the room and gasps, I look up and she is completely naked. Her c-cup breasts are topped with small, pink and perky nipples that look fun to suck on. I glance down her body and see her bald pussy, complete with inner lips that look very sexy in her small thigh gap. Once again, I feel my cock grow hard as I fight to tear my eyes off of her.

Before either of us can say anything, Rachel pulls the door closed and I can hear her footsteps leading away from the room. A minute later, she comes back and knocks on the door, "James? Do you mind if I get dressed in there?" She asks through the door.

I pause my game and stand up, crossing the room and opening the door. Rachel is now wearing a soft looking white bathrobe. She looks intently at me, trying to read my body language with her piercing green eyes. "Ummm... go ahead..." I say, at a loss for words, leaving the room and the door open for her. Rachel just nods and walks into the room, closing the door behind her. A couple of minutes later, she calls for me to come back inside.

I slowly open the door and find my sister wearing black leggings with a blue stripe going up each leg and a concert shirt for her favorite band. "I'm going out!" She announces to me and before I can respond, she just leaves the room and I hear her open then close the front door, leaving me alone in the house. I look out the window and see her car drive down the street. I go back to laying on my bed, trying to forget the past half hour and go back to the improved relationship that we had just started.

As time goes by, I find that forgetting what I saw is much easier said than done. The smell of my sister's cum is faint but still there and the images of her fucking herself with a dildo and her full frontal naked body are burned into my mind. Just the thought of it makes my cock grow hard. Finally, I give up playing video games and decide to do a little snooping. I go to Rachel's side of the room and look under her bed, finding nothing but some shoes. I then go to her nightstand and open the top drawer.

"Bingo!" I say out loud, finding what I am looking for. Inside is a flesh colored dildo about 7 inches long and about 1.5 inches wide, complete with veins, a head and a fake ball sack. The base has a suction cup. Next to it is a partially empty bottle of lube, claiming that it increases her pleasure.

"You dirty slut!" I say, imagining this dildo sliding in and out of my sisters sexy, bald pussy. I feel an urge to jerk off, harder than I've ever had the urge to do so before. I finally give in, going into the bathroom and making sure the door is locked. I strip, open the photo of Rachel on my phone and begin to jerk off. I imagine that instead of the dildo sliding in and out of her pussy, that it is my cock.

+++++

After I finish and clean up, I go back to the room and try to forget the whole thing. Part of me feels guilty for taking a picture of my sister, while a darker part of me is excited by the prospect of it. Not only had I seen her naked, I knew that she was sexually active as well.

I hear a car pull up to the condo and go back to video games, pretending everything was normal. The front door opens and closes a second later. I then hear footsteps come up the stairs before Rachel pushes the door to our room open. "Can we... We need to talk." She says.

I turn off my TV and ask, "About what?"

Rachel sighs, "You know what we need to talk about! You saw me naked and..."

I shrug, "What's the big deal? It was a one-time thing."

Rachel gives me a smug look, "You sure it was a one-time thing?"

I feel a burning in my cheeks. Shit she knows! I think before saying, "Okay, maybe I saw you..."

Rachel gives me a shit eating grin, "Saw me what?"

"Playing with yourself." I say quietly.

Rachel looks me in the eye, "And did you like what you saw?"

Where is she taking this? I struggle to speak, "I mean you're a pretty woman and you have a nice body. But..." Saying those words brings the images of Rachel naked back into my mind, making my cock grow hard. I try to cover it up with my hands and hope she doesn't notice.

"Well you clearly are enjoying thinking about it now." Rachel says, moving my hands away from my lap.

I give her a hurt look, "I think it would be best if we forgot about the whole thing and pretend it never happened."

"Why do you suggest that?" Rachel asks.

"Well you're my sister and that's weird..." I start to say before I'm cut off by her grabbing my cock through my pants.

"You think it's weird that you saw me naked?" Rachel asks, slowly stroking my length.

I gulp, "Yes?"

"You don't sound too sure about that to me." She replies.

"Look... what do you want from me?" I ask, hoping she doesn't know about the picture I took.

Rachel pretends to think for a second, "Well... there is one thing. I haven't really found any guys that I like at school. That means no sex. And my bitch of a roommate never leaves so I can't really masturbate so basically..."

"You want me to leave so you can... do your thing?" I ask, just wanting to put this whole thing behind us.

Rachel smiles, "Just the opposite of that." She pulls her shirt over her head, revealing a red lacy bra that accentuates her pale skin nicely. I feel my cock twitch just at the sight. I quickly toss my shirt over my head. Rachel then tugs down her leggings and panties together, revealing her pussy and her sexy inner lips. My cock is now fighting to escape my pants and I undo my fly, letting them fall to the floor.

Rachel smiles at me, now only wearing her bra and I'm only wearing my boxers. "Is this really what you want?" I ask, knowing what happens here will change our relationship.

My sister nods, a hungry look in her eyes. She drops to her knees in front of me and tugs down my boxers, letting my erect member flop out. She grabs the base and points it straight up. My cock is about 8.5 inches long and 1.5 wide. I push myself up on my elbows allowing me to look Rachel in the eyes. Rachel looks back at me, brushing several strands of hair out of her green eyes and takes the head of my cock in her mouth. Holy shit she's good at this! I think as my sister begins to suck my cock.

Rachel soon begins to move on from the head of my cock and begins to work my shaft with her mouth as well. I groan, the guilt of taking a picture of my nude sister and then watching her rapidly fading away. These feelings are replaced with a strange lust, different and more forbidden than I've felt before.

Rachel pulls her mouth off of my cock, leaving it covered in her spit. Replacing her mouth with her hand, she slowly begins to stroke. "You liking this?"

I smile at her, "You know it!" The two of us move our faces close together, before I move in and begin to kiss her on her lips. We start slowly at first, but soon it becomes more passionate and our tongues begin to explore each other's mouths. Rachel and I pull apart, both clearly enjoying this new part of our relationship.

Rachel climbs up on the bed next to me and spreads her legs, giving me a perfect view of her pussy. She is sitting up slightly, allowing me to reach behind her back and unclasp her bra, which I immediately add to the pile of our clothes at the foot of the bed. My sister's medium breasts are freed, exposing her hard, pink nipples to me. I begin to feel them, enjoying the hardness of her nipples and the softness of her breasts.

The two of us begin to kiss again while I begin to feel her body, getting used to the toned feeling of her stomach before giving her pussy a tentative touch. Rachel shudders as I slide a single finger inside her, feeling her tightness and how she is dripping wet. Rachel slowly begins to buck on it, encouraging me to insert a second, causing her to pull away from my mouth and let out a soft groan. "Fuck... that feels good..." She sighs.

I pull my fingers from her pussy and move down her body, positioning my face in between her thighs. Her pussy is visibly wet, some of her juices covering her soft lips, making them shine in the light. I lower my mouth to her, beginning to lap at her pussy eagerly, making her groan in pleasure. She tastes so good! I think, pushing any rational thoughts about us being related out of my head. Instead, I focus on one thing, pleasuring the beautiful woman in front of me. I look up at Rachel's face while continuing to pleasure her with my tongue. Her eyes are closed and her face is contorted in pleasure.

"I'm about to cum..." She moans. I pull my mouth away from her pussy and go back to fingering her, letting Rachel furiously rub her clit. Her moans grow in volume until she lets out a loud, "Fuck! Fuck! Fuck!" as she cums.

Rachel throws her head back as I feel her pussy clamp down on my intruding fingers, which are soon coated in her warm, white cum. My sister's moderate breasts heave as she enjoys her orgasm. While she cums, she humps my fingers slightly, while also slowly rubbing her clit. Recovering, Rachel opens her eyes after a moment and smiles at me, "You ready to take this further?" She asks.

"How much further?" I ask her, not wanting to rush forward into this new, unknown and forbidden relationship between us.

She smiles at me and rubs her clit slowly, "I think you know the answer."

"Well in that case..." I grab her thighs and stand up off of the bed, pulling her to the edge. She lets out a giggle as I do so. I grab the base of my cock, rubbing the head on her slit, feeling her warm entrance and wanting desperately to slip inside her. I place my hands on her hips while I begin to fuck my own sister.

She raises an eyebrow at me, "Well... waiting for an invitation or something?"

I gently ease the head inside of her and Rachel lets out a soft sigh. I slowly slide my cock deeper inside my sister, enjoying the feeling of her warm and wet hole. As I sink deeper inside my sister, she lets out a groan as she takes my length. After one thrust, she has taken about 6 inches of me. "You like the feeling of your big sister's pussy?" She asks, making sure to squeeze her muscles around my cock.

"I love it!" I say, slowly sliding back out of her. I begin to slowly fuck my own sister, having very mixed feelings as I do so. Rachel begins to sigh softly each time my cock reaches deep inside her. As I pull away, I pull her pussy lips from her body slightly.

Looking me in the eyes, Rachel begs, "Faster!" I shift my grip from her hips to her shoulders and begin to fuck my sister faster than before. The sound of skin hitting skin fills the air as she grunts with each impact. Her breasts bounce up and down as I feel my urge to cum grow.

"I'm going to cum!" I groan.

Rachel grunts, "My face..."

I pull out of her dripping wet pussy and Rachel gets down onto her knees in front of me, making sure to close her eyes. I stroke my length several times, my sister's juices coating it. Finally, my cum shoots out and coats my sister's face. The first strand shoots up the middle of her face, covering her nose. The next shoots lower, hitting her lips, which she licks off, enjoying the taste. The rest coat her chin and lips, which makes Rachel smile and open her eyes.

Holding my now deflated cock in my hands and feeling slightly guilty about what happened, I start to say, "So..."

Just then, I become quiet as I hear the downstairs door open and Mom call up the stairs, "Rachel? James? You two home?"

"Shit!" I whisper.

Rachel just looks at me, before calling down to Mom, "We're in our room. I'm just going to go take a shower." Before she stands, and walks out of the room, giving me a seductive smile as her hips sway side to side. Watching her makes my cock become semi-erect once again.

Worried Mom might come in and see me, I grab my boxers, pants and shirt, quickly dressing to make things look normal. I quickly fix my bed then throw on my TV and pretend to be watching something. I hear Mom's footsteps come up the stairs followed by her appearing in the open door.

Mom looks exactly like an older version of my sister. She is slightly shorter and has larger breasts. Mom looks around the room with the same piercing green eyes as my sister before settling them on me. She asks, "How was work today?"

"Good. I got to come home early cause there wasn't anything to do. How was your day?" I answer as normally as possible.

Mom smiles, "Good. It's nice to be done for the day. Listen, how is sharing a room with Rachel? Are you two getting along?"

I shrug, trying to push the memory of how my sister's pussy gripped my cock while I fucked her. "It's not so bad. We get along pretty good."

Mom's smile grows, "That's good! I was worried about it at first but since everything seems to be working out, that's not an issue."

I nod, "Yeah. It's going to take some getting used to but I think we can make this work." I shook my head as I opened the snapchat before walking into the condo that Mom, Rachel and I all share. My sister had just sent me a video snap of her legs spread wide on the bed and using her free hand to plunge her dildo in and out of her pussy with the caption Thinking of you. There is no sound, but it is clear that my sister is enjoying her alone time.

Just seeing this video makes my cock become semi-erect. God she's hot I think, opening the door and walking inside.

"Hello?" Yells my sister from upstairs.

"Just me!" I call back, going to grab some food from the kitchen before I head upstairs.

As I walk up the steps, I listen for heavy breathing or any moans coming from our room that would indicate that Rachel is masturbating. Reaching the top of the steps, I see that the door is open only a small crack. I think back to the other day, the first time I caught my sister pleasuring herself. My phone seems to grow heavy in my pocket almost as if to express the guilt of still having the pictures of Rachel. Does she even know about them? I ask myself.

I slowly push the door open and gasp in surprise at what I see. Rachel is laying on the bed, her legs spread wide and some of her cum slowly dribbling out of her pussy lips. "I've been waiting for you!" She says with a smile.

I feel my cock harden at the sight of my naked sister, "Rachel... come on. Doing this once was bad enough, why do we have to do it a second time?"

Rachel gives me a seductive smile, "What's a matter? Afraid of your own sister? If I remember the other day correctly, you seemed to have a lot of fun too." She stands and begins to walk toward me, her hips swaying side to side before she reaches me and runs a hand from my sternum to my now fully erect cock.

She presses her bare breasts into my body, clearly teasing me. "You really want to do this?" I ask.

Rachel just gives me a smile and slips her hand inside of my pants, stroking my length through my underwear. "It really feels like you want this too."

She's right I think. Rachel had been more fun that my last girlfriend. I sigh, "If we do start having regular sex we need to make sure not to get caught." I say.

Rachel smiles at me and uses her free hand to tug my pants down, "Don't worry! I'm really good at not getting caught, especially after dealing with my bitchy roommate."

"The one who never went anywhere?" I ask.

"That's the one." Rachel confirms, tugging my boxers down, revealing my hard cock, her hand grasping it just below the head.

"I guess as long as we don't get caught by Mom..." I say, trailing off as my sister drops to her knees and licks the head of my cock. She begins to stroke my length while sucking my head, clearly enjoying doing so.

Rachel removes her mouth from my shaft, "You going to have all the fun?" She asks in a teasing voice.

I shake my head, "If you just follow me to the bed here..." I say, helping her up and tossing my shirt to the floor. I lay down on the middle of the bed, while Rachel climbs on top of me. She positions her pussy above my mouth and leans forward taking my cock into her mouth once again. I start to play with her delicate folds, spreading them with my fingers before licking her entrance with my tongue. I can taste a little of her sweet and forbidden cum left over from her masturbating earlier.

I slowly begin to rub her clit, while also licking her pussy, enjoying the taste of her juices. Rachel takes her mouth off of my cock for just long enough to let out a soft moan of pleasure. The two of us continue to enjoy the feeling of the other's mouth. As I bring my sister to orgasm, she stops sucking me and begins to let out moans of pleasure. I continue to work my sister to orgasm, sometimes slipping my tongue just past her entrance.

Rachel's moans become louder as she nears orgasm. Finally, I push her over the edge and she lets out a squeal of pleasure. I feel her thighs begin to quiver on either side of my face and slowly, her cum begins to drip out of her warm slit. I greedily lap up this forbidden fluid, enjoying the taste as well as the sound of bringing my sister to orgasm. As her orgasm subsides, Rachel lifts herself off of my face and moves down my torso, until she reaches my cock.

Grabbing my shaft, which is covered with her spit, my sister holds it still while slowly lowering her body until she is just above my cock. Rachel runs the head of my cock over her warm and wet slit for a few seconds. As she does so, she makes a mmmmhhhhh noise. "What? You starting to think this is a bad idea now?" I ask, teasing her.

Rachel looks over her shoulder at me with a smile on her face, "We still have a fairly long time until Mom comes home. Why would I want to rush this?"

She goes back to rubbing the head of my cock over her entrance. Some of her flowing juices begin to dribble onto my length, coating it. Finally, my sister sits up slightly and sinks down onto my cock, letting out a loud sigh as she does so. She begins to slowly bounce up and down on my cock, letting both of us enjoy the experience. I enjoy the warm, wet and forbidden feeling of being inside my own sister. As she does this, my sister lets out sighs or the occasional low moan of pleasure.

I reach out and caress the curve of her ass. It is a little soft, but clearly something Rachel is proud of. Feeling me do this, Rachel takes my whole length in her pussy and begins to grind on my cock. When she moves her body forward, her ass parts, giving me a glimpse of her small, pink asshole. I run my thumb over it and I can feel her shudder. Rachel reaches behind her back and grabs my wrist, gently tugging it away from her asshole and relocating it to the curve of her hip.

"Please don't do that..." Rachel says. Before I can reply, she suddenly begins to ride much harder. Each bounce of her torso leaves just my head inside her before she slams back down onto my cock. Her moans become louder and more frequent, while her breathing becomes heavy.

As her moans become louder and her pussy wetter, I feel like I can't hold off cumming any longer. "I'm gonna cum soon..." I moan.

Rachel gives no indication that she heard me and continues to ride me hard. Finally, she lets out a cry of pleasure as my sister cums. I feel her pussy clamp down on my cock, milking the cum out of me. Inside of her pussy, our cum mixes together and I can feel the warm mix of fluids begin to trickle down my length and out of my sister. Rachel sits up off of my, leaving my now soft cock dripping her natural lube and some cum.

As she kneels on the bed above me, her pussy begins to drool cum, which begins to run down her soft inner thighs. She smiles back at me. Breathlessly, my sister asks "Want to help me get cleaned up?"

I nod and stand up on the floor, helping her to her feet as well. I follow Rachel to the shower, admiring her sexy rear and the shiny mix of cum now covering her inner thighs. There are several strands connecting the fluid on her legs to her delicate lips. Rachel climbs into the shower, giving me a seductive smile and motioning with one finger for me to follow her. I step in and close the curtain behind us. Instead of turning the water on like I expected, Rachel looks at me.

"Feel my pussy!" Rachel orders. I wordlessly do, first rubbing my fingers over the outside. They become coated in warm cum. Then I slowly insert two fingers inside her. Not only is there cum inside her, but her juices are flowing like crazy.

"Your soaking wet!" I exclaim, twisting my fingers around inside her, giving her pussy a little tease.

Rachel looks at me with her intelligent green eyes, "You know how much having my little brother's cum inside me turns me on?" She asks, slowly stroking my member.

I feel the blood begin to rush back into it, "Well now I know." I say, leaning forward to kiss her on the lips. We start with a gentle kiss, however, as she strokes my length and I knead and squeeze her breasts, our mouths part. Soon, our tongues are exploring each other's mouths.

We part for a second, staring into each other's eyes. Rachel slowly strokes my hard member, some of her fluids still dripping off of it. Without breaking eye contact, Rachel guides the tip into her vagina. I sink inside, forcing the last of the cum out of her. This cum begins to drip down our legs and onto the shower floor. Rachel moves close to me, her hard nipples pressing into my body.

I begin to slip in and out of her wet pussy, making my sister moan in pleasure. As I fuck her, I begin to rub her ass, enjoying feeling it. Rachel reaches between us and rubs her clit and moans loudly. The two of us fuck in the shower, the warm cum from earlier dripping onto the floor and Rachel's moans of pleasure filling the air. Her moans become louder as she nears orgasm, and once again, I push her over the edge.

I feel her pussy clamp down on my cock while her warm cum coating my length. I slow the pace of my thrusts and let Rachel enjoy her orgasm. I look at her pretty face and see it is contorted in pleasure. Her eyes are closed and her mouth is open into a circle as a series of squeaks comes out of her. As my sister begins to recover, she opens her eyes and has a lustful look in them. "Keep going..." Rachel begs me, staring into my eyes.

I smile back at her and once again begin to pump in and out of her. I start slowly, but after several seconds, Rachel begs, "Fuck me hard and fast! Like a slut!"

"Like a slut you say..." I reply before grabbing her hips to keep her in place. Rachel gives me an encouraging nod and smile. I begin to rapidly slide in and out of her, making her moan with pleasure. I feel myself about to cum again and thrust as far as I can into my sister's cunt. Rachel lets out a cry of pleasure as rope after rope of cum shoot inside her. Having came not too long before, this load is smaller than the first, but neither of us really care. As I cum, Rachel and I hold each other tightly, her perky breasts pressing into my chest. Both of us are breathing heavily and I can feel her rapid heartbeat.

Having finished my orgasm, I slide my drooling and limp cock from my sister. Rachel lets out a soft sigh as some of my cum follows my cock out, dripping down her already messy thighs. Some of it drips straight to the floor between her legs, but most of it coats her soft lips and thighs. Rachel and I pull apart, smiling at each other. Her hair is a disheveled mess and she has started to sweat, but she still looks very pretty.

Rachel gives me a smile, "Brother dearest, would you mind turning on the water? I'm a bit of a mess here."

I laugh, "Yeah no problem. We probably should clean up quickly because Mom will be home soon."

Rachel nods and sighs, "Unfortunately your right." The two of us begin to quickly clean the sweat and cum off of our bodies. I leave the shower first, grabbing a towel to dry off with first and heading back to our room. After I'm dressed, Rachel comes in, drying herself off.

As she begins to dress, the front door opens and Mom calls up, "Hello? You two home?"

"In our room!" I call back, motioning for my sister to hurry up and get dressed. The sound of Mom's footsteps coming up the stairs motivates Rachel to dress quickly, throwing a shirt on over her bra. As the door opens, Rachel sits down on her bed and begin to look at her phone, trying to act as naturally as possible. "What did you two do today?" Mom asks, looking between us.

Mom always looks pretty when she comes home from work. Her hips and probably d-cup breasts are shown off nicely by her outfit, which consists of fishnet stockings, a tight dress that goes to about her knees and a matching tight blouse. Despite being in her mid 40's, Mom still looks like she is 37 or so.

Fuck! Does she know? I ask myself. Fortunately, Rachel says, "Not a whole lot. Just kind of hung out, the usual stuff. How was work?"

Mom shrugs, "Same thing as usual." Mom goes on to tell us about her coworkers and how much she dislikes almost all of them. Thank god she didn't figure it out... I think. Suddenly, I hear my name being called and snap out of my trance to see both Mom and Rachel looking at me.

"What was that? I wasn't paying attention." I say.

Mom rolls her eyes, "You never are. I just asked what you wanted for dinner. Your sister is going out, so it's just you and me."

"Oh. I don't really care. Pizza maybe." I answer.

Mom nods, "Alright. I'm going to go order in a few after I put my stuff down." Mom leaves the room and the sound of her footsteps fades slightly as she walks downstairs, once again leaving Rachel and I alone in our room.

"Where are you going?" I ask.

Rachel looks up from her phone for just long enough to respond, "Out with a few old friends from high school."

I nod, "Well, have fun."

Rachel doesn't look up from her phone this time, "You too."

She wasn't even paying attention to what I said. I think, wishing for once Rachel wasn't addicted to her phone. After about 10 minutes, Rachel gets up to leave and the two of us say goodbye with a fairly affectionate hug. Since we started having sex, our hugs went from a simple embrace to her rubbing her hips on me, almost like she is grinding on me.

Rachel then walks out of the room and I hear her and Mom talking for a minute before Rachel leaves the condo. I head downstairs into the kitchen and find Mom watching the news on the small TV in there. The two of us begin to make small talk, drowning out more of the same talk of politicians and scandals. Finally, the pizza arrives, and Mom goes to pay for it while I get out plates. Mom comes back with the box and the two of us begin to eat. We eat in silence for almost the whole duration of the meal. As we begin to finish, Mom turns the TV off and turns to look at me.

"So, do you mind sharing a room with your sister?" Mom asks suddenly.

I shrug and finish the last bite of my pizza. Mom just looks at me, as if waiting for me to explain. I swallow then say, "It isn't so bad. Rachel and I seem to be getting along much better now than we did when she still lived here full time."

Mom nods, a serious expression on her face, "You sure that's the only reason?"

"What?" I ask, feeling myself go pale. She must know... otherwise she wouldn't have said anything.

Mom brushes a stray black hair out of her face, "Oh come on, did you expect me not to find out?"

"Notice what?" I ask, pretending to play dumb.

"Cut the shit and be straight with me! Yesterday when I got home, that room smelled like sex. I can't picture either you or Rachel kicking the other out to get laid and the one who was kicked out not tell me. So that leaves me with only one conclusion, the two of you are sleeping together." Mom says all this sounding oddly calm.

Fuck... I guess lying will only make things worse... I think before saying, "We did..."

Mom nods as if she was expecting this answer, "How many times?"

"Twice today and once yesterday." Is my answer, my face going from pale to bright red in embarrassment.

Mom nods again, "Was this your first time?"

It is my turn to nod, "No. Why aren't you mad at Rachel? She was the one who initiated this whole mess!" I yell the last part at Mom.

Mom just keeps a straight face, "I'm not mad at either of you Your sister is very open with me, told me about her first time and most of her sexual encounters, including you two yesterday. You on the other hand, don't tell me anything."

"So you're okay with this?" I ask.

Mom sighs, "I don't know if okay with it is the right word. You two are both adults and can make these decisions for yourselves."

"So that's it? You only wanted to tell me that you know Rachel and I... had sex?" I ask.

Mom shakes her head, "Not at all, just hearing your sister tell me about it really turned me on."

"Where is this going?" I ask, feeling nervous all of the sudden.

Mom stands and walks over to me. I've never been afraid of the woman who gave birth to me and raised me until this moment. What is she doing? I ask myself. Mom starts to smile at me as she sits on my lap, facing me. She plants a kiss on my lips. Soon, the two of us begin to kiss passionately, hands beginning to explore the other's body.

Holy shit! I can't believe this is happening! I think as we part lips to take a breath. Mom smiles at me and grabs my hand. "Let's go somewhere a bit more private." She leads me upstairs, past Rachel and I's bedroom to her own bedroom. Once we pass the door, Mom and I begin to kiss once again. My hands quickly begin to reach behind her and grope her large, soft ass. I feel a zipper and slowly slide it down, exposing her lacy pink panties to the air. Mom's hands begin to gently rub my hard cock through my pants.

Our lips part once again and we both begin to lose our clothes. Mom tosses her blouse to the side while I drop my pants and boxers with one swift motion. With another, I lose my shirt as well. "It seems I'm a bit over dressed for the occasion!" Mom laughs, motioning to her matching bra and panties.

I smile at her and grab her hand, leading her to the bed, "Doesn't matter to me." Mom smiles back at me as she falls back onto the bed, spreading her legs wide. She reaches behind her back and unclasps her bra, giving it a toss to the side. Her large breasts are exposed, each topped with a large, pink nipple, both of which are visibly hard. Hesitating for a fraction of a second, I almost immediately begin to play with Mom's breasts. I begin to knead them and pinch her nipples, causing Mom to look at me with lust in her eyes.

Mom grabs her panties and pulls them down her sexy thighs slightly. Her pussy looks wonderful. She has a mound with her soft inner lips poking out of her sexy outer ones. Above her slit, she has a small, well-groomed patch of black hair. I reach out and feel Mom's pussy with a shaking hand. You've done this before, how different can your own Mom be? I ask myself. I pull her panties down all the way and begin to lap at her folds with my tongue.

To my surprise, Mom is already very wet and soon begins to let out soft moans of pleasure. I grab onto her hips and continue to work her entrance and clit with my tongue, occasionally pushing it inside her. Mom's moans grow louder and finally she cums. She cries out in pleasure and her forbidden cum begins to flow out of her mound. I greedily lap it up, enjoying the taste.

Suddenly, I feel Mom's hands nudging my head away from her. I look up and Mom is breathing heavily, her piercing green eyes staring into my own. "I need you inside me right now!" Her voice is full of lust.

I shift my head away from her pussy and walk on my knees in between her soft thighs. As I go to push my cock into her soft folds, Mom beats me too it, sliding herself towards me. Her drooling mound envelopes my cock and Mom lets out a groan of pleasure. I grab just above her hips and begin to slip in and out of her. "Oh fuck Mom... you're so tight..." I groan.

As if to tease me further, Mom squeezes her muscles, clamping them down on my member buried inside her pussy. I begin to pick up speed and soon the two of us are breathing heavier, our grunts filling the air. Mom's tight pussy hugs my cock, almost forcing me to cum. Mom's breasts bounce wildly as we enjoy the new intimate feeling of pleasuring each other.

I soon feel myself about to cum, "I'm getting close Mom..." I gasp.

"On... my tits... baby... fuck..." Mom gasps out. I pull my cock out of her dripping mound and straddle her stomach. I stroke my length several times, my hand becoming coated in Mom's natural lube. Finally, I groan and shoot my load. Several strands of cum shoot across her large, pink nipples and into the crevice between her soft orbs.

Having finished cumming, I collapse next to Mom on the bed, both of us breathing heavily. I can't believe that just happened. I keep thinking. As both of us go back to our normal breathing, Mom begins to rub my cum over her breasts and nipples. Where she does this, her skin becomes slightly shiny in the light.

After several minutes, Mom stands, "I can't remember the last time I had sex. Thank you for that."

I smile up at her, "Any time."

Mom smiles back, "I think I'll take you up on that offer. One thing before I go shower though."

"Yes?" I ask.

"Don't tell your sister. Something tells me she wouldn't exactly be happy having to share her newest friend with benefits." Mom replies before walking into her bathroom. Her hips and soft ass sway side to side. What the fuck did I get myself into? I think before standing and making my way to the other bathroom to get cleaned off.
