What Goes Thump In The Night

dezurtdawg©

Hey guys and gals, been off the radar for a while here as life took precedence over writing! Getting just a little bit of time free now so I will slowly get back to posting stories for you, my fans, to read. Hope I haven't lost my touch! Just a reminder, all persons and events are total fiction thought up in my twisted brain. If you don't like brother-sister incest stories or anal sex, then I suggest you skip this one.

********

I awoke to a strange sound. My eyes focused on my alarm clock seeing it glowing 11:32P. What the hell? Thump ... thump ... thump ... thump... I listened as the rhythmic sound continued as my brain became fully awake. I listened for any other sounds, like maybe the wind was making something bump against the house or something. Nothing. Nada.

Thump...thump...thump... it was getting harder now and a bit faster. Thump...thump...thump... it just kept going slowly picking up the pace of its thumps. I got out of bed and rubbed my eyes again as I opened my door and walked down the hall. My parents weren't up, having gone to bed shortly after ten, just a little after my sister and I had. I cocked my head and listened. I could still hear it but it was softer so I went to the kitchen and turned on the light.

Nothing seemed amiss in there and I listened again. Very faintly I heard it, thump...thump...thump...thump... then it got faster still, thumpthumpthumpthumpthumpthump and then it just stopped. Total dead silence overtook the house. What the heck was going on? I gave up figuring this out so I turned off the light and headed back to bed.

Just as I neared the door to my room my sister stepped out of her bedroom making each of us jump in a mixture of fear and shock as we both gasped out slight versions of "Oh shit! You scared me!"

Her eyes still quite large Rebecca quickly whispered, "What are you doing up?"

"I heard a noise and was investigating it."

She had a funny look briefly then said, "Um, me too. What was it?"

"Don't know, I couldn't find the source. G'night sis."

"Okay Tom, g'night. I've got to pee."

********

The next morning I mentioned the noises to our parents and asked, "Did either of you hear anything last night?" My dad has sleep apnea so he uses one of those noisy air machines. Mom wears ear plugs to shut out the noise.

They looked at each other then dad said, "That'd be a first! That is why we have the security system. It didn't go off did it?"

"No dad, I think I would have mentioned that if it had. Geez."

"Well then it was probably just the wind," mom said as she handed our breakfasts to Rebecca and I with a smile.

"I guess," I said slowly and took a mouthful. I noticed sis hadn't said a word about hearing it, even as she sat there listening intently to every word I said.

Soon both mom and dad left for work after giving us the list of chores they wanted done. We always acted put out about the chores but they did give us something to do all day during summer vacation. I turned 18 two months ago and will be a senior in high school this fall. Rebecca will be a sophomore at the local college. She is a real book worm, studies all the time and I can't remember the last date she had. I think that is odd because she is a babe if I do say so myself. I'll be honest, I've had visions of her during my wanking sessions. Of course, I've also imagined my mom, my friend's mother, and even Ms. Huxtable who was my 8th grade English teacher. She was smokin' hot!

On my list were two outdoor jobs; mowing the lawn and cutting back some bushes. It was a beautiful day and I did them quickly so I could go over to my buddy's place and play computer games. As I downed a glass of iced tea I thought, 'what the fuck?' as I heard it again. Very softly thump...thump...thump... Shit, am I going mad? Sure it was kind of like a back beat to music that my sister likes but it was there, none the less.

I rinsed the glass and then made another sweep of the house. At the front door I couldn't hear it at all, and the same by our parent's bedroom door which is on the opposite end of the house from my bedroom. As I walked away from mom and dad's room I heard it softly again, and it kept getting louder, louder and faster. Thump ...thump...thump...thump...thumpthumpthumpthumpthump... thumpthumpthumpthumpthump.

It wasn't coming from the bathroom where I needed to take a shower. I stepped into my room and I could hear it really loudly. I walked around my room and it was loudest on the wall common to Rebecca's room. What the fuck?

I walked over to her door and turned the knob only to find it locked. Huh? Her music was playing loudly but I could still hear it outside her door, thumpthumpthumpthumpthumpthump as fast as I had ever heard it.

I gave a knock on the door but her music was too loud and she didn't hear me. Shit that thumping was really loud and fast now! "Hey sis," I yelled, "open up!"

The thumping noise grew softer and slowed then grew in speed and intensity once again. I stood there staring at her door like a moron. Finally I turned the knob with one hand giving the door a shake while my other hand pounded on it as I yelled as loud as possible, "SISSSS! Open UP!"

I heard one more yet softer thump and then some strange noises before Rebecca opened her door looking frazzled. "WHAT!?"

"What are you doing in there?"

She looked upset, then said, "I was moving furniture. You got a problem with that?" Then she pushed past me and stepped into the bathroom.

"Hey, I need a shower!" I called out to her.

"Yes you do, stinky, but I got here first!"

She closed the door as I muttered unkind words at her. And then I poked my head into her room and looked around. Hum, it didn't look different from last time I was in here. Smelled odd though. But after giving her room a cursory once over I went back to the kitchen for more iced tea while waiting for the bathroom.

I didn't hear that strange noise for over a week. Hell, I'd totally forgotten about it. But then I awoke to it at 11:47P as I stared at my alarm through sleep shrouded eyes. Fuck me, there it is again. Thump...thump...thump...thump at a slow well spaced pace. I sat up and listened, yup there is a wind tonight. But could the wind be making that sound? Again I paced around the house, listening.

It was soft in the kitchen, non-existent by our parent's bedroom, and fairly audible in the family room as well as the living room. What the fuck? I took a leak in the bathroom and it was fairly loud in there, then I stepped up to Rebecca's room. It was definitely louder outside her door. It was louder and faster, occasionally very loud. Thump... thump...thump...thump...THUMP...thump and then it got really fast thumpthumpthumpthumpthumpthump. I put my ear to her door and shit it was loud! It sounded like she was having a bad dream as she moaned and groaned every now and then, just like she used to on stormy nights.

Carefully, silently I tried her door knob. It was locked. The noise got really fast and then it simply ... stopped. It sounded like she was moving around in there so I quickly fled to my room and closed my door. Then I heard her door open and the sound of feet walking into the bathroom.

I entered her room and turned on her light. It didn't look different. Still there was that strange odor. She needs an air wick or something! I heard the toilet flush so quickly I turned off her light and left her room heading to the bathroom. She opened the door just before I got there.

"SHIT!!!" she screamed seeing me in the dark hallway. "Damn it Tom, you scared me!" Her eyes looked funny in the dark but I couldn't really tell. "What are you doing up?"

"I could ask you the same question," I said watching her face. "I heard that noise again, then it stopped and I need to pee. Um, did you hear anything?"

"Uh, nope! But I had to go bad too. Bathroom's all yours."

With that she slid past me and closed her bedroom door behind her. I peed and then listened more than slept the rest of the night. I never heard that sound again that night.

I didn't mention the sound to my parents at breakfast. I figured why bother since you couldn't hear it outside of their bedroom door. Around ten, as it was Saturday, mom and Rebecca went shopping and dad went to play golf. That's when I began to snoop.

Now don't get me wrong, I'm no super detective or anything like that, surely I'm no Sherlock Holmes! But I knew that sound was coming from my sister's room. I was looking every where and getting quite frustrated as there was just nothing out of place. Nothing seemed strange to me, which in and of itself seemed strange. I mean, her room was usually neat but not this neat!

So out of desperation I got down on my hands and knees and started looking around again. Things look different from down there. Suddenly I said to myself, "What the fuck is this?" She had her desk in a corner with one end against our common wall. On the opposite end were several round smudges, like suction darts had been stuck there, only these were very large darts!

As I studied them I noticed that her room's strange smell was really intense there. Her carpet was dampish and slightly sticky. I moved my finger from the carpet to my nose and was nearly overwhelmed by the odor. What is my sister doing in here? It may sound disgusting to you, but I leaned way down and put my nose right above the carpet and inhaled. I inhaled again, deeper this time. Wow was it ever strong, but up close I thought, "I kinda like it!"

Standing up again I looked at those ring smudges again and noticed they were lower than the bottom of my knees. Hmmmm. So I started carefully going through her drawers and closets. Nothing. So I went through them again, slower, carefully digging deeper.

Ho ... ly ... shit! I struck pay dirt! Make that the mother load! Buried under several pairs of sweatpants was a dildo! Not just any dildo, this fucker (ha, ha, I made a pun!) was lifelike in a gigantic way! I mean, it was nearly as long as my forearm and really thick. It had one hell of a bulbous head and thick veins sticking out all over it! And on the base was a big suction cup that was the exact match to the rings on her desk. Holy mother fuck!

My sister, the one who never dates even though she should be getting asked out every night, my sister is fucking her desk! I was still kneeling by the end of her desk and I just sank down onto my ass there, staring in disbelief at the fake dick in my hand. I'm not sure what made me do it but slowly my hand lifted it to my nose and I smelled it. Oh gawd, it smelled just like her carpet. Just like the odor that hung in her room right after the noises. My sister, that horny little bitch!

Very carefully I replaced the dildo exactly where she had hidden it. No point in arousing her suspicions about me. Then I looked at her door lock and door frame. Wow, I couldn't believe it! All those times when she slammed her door after an argument with our folks had slightly dislodged the board that stops the door from swinging right through it. I have no idea what that is called. Anyway, I found out that I could use my student ID card and slide it under that board and her lock would slide right out of the way! Presto chango! Her locked door could be opened just like that!

Leaving her room exactly as I had found it I went to my room and jacked off a huge load thinking about my horny sister fucking away against her desk. The vision told me that as she did it, her ass was pounding back right towards the head of my bed! God I shot a huge load of cum when I realized that. After cleaning up I took a much needed nap and dreamed about my next move.

I was so anxious to catch her in the act that the next three nights I sat up waiting for her tell tale 'thump' sound. Shit, I never heard a thing! In fact, mom thought I was getting sick since I was so lethargic the following day because of my lack of sleep. It wasn't until Wednesday that I hit pay dirt.

Being my devious self as soon as our folks left for work I told Rebecca that I was going to head over to my buddy's place and do video games. She watched me leave so I knew someone would be making noise soon. Too bad for her she didn't wait to make sure I didn't come back home. I made a loop around the neighborhood and was back in about ten minutes.

The house was locked when I got back, making me certain that she was pounding her ass on her favorite desk attachment. I relocked the front door and listened for the sounds. I didn't hear them until I had moved about thirty feet closer to her bedroom. As I got closer and closer I realized she was letting it all out today. The thumping sounds seemed much harder and for the first time ever I heard her moaning in time with the thumps.

When I stopped just outside her room I was amazed at what I heard. I could almost see her in my mind as the hard 'THUMP' was accompanied by a harsh sounding "Umph" as she gasped while thrusting her pussy back onto her rubber man. Then a slowish groan as she pulled forward and nearly off of her dildo before another loud THUMP/UMPH sound. She was really into it today. Guess that's what happens when she lets a few days go between fucks!

I gently gave her door knob a twist but it didn't budge. You can't be too careful, even when nobody else is home, I guess. Carefully I slipped my ID card between the main door frame and that thin board I mentioned before. My left hand was on the knob and I felt it as the door slipped open an inch. SUCCESS! I pushed it another inch letting me hear her much louder noises now.

As luck would have it, as the door slowly opened she was right in my line of sight and her head was hanging down, letting her look at her knees or her over stuffed pussy, who knows which? She sure IS a moaner! THUMP/"OOOHHH", "MMMMMM", THUMP/"OOFF", "UHMMMM" THUMP/"UMPH".

Silently I slipped into her room and carefully closed her door, not making a sound. She was naked and her 34B tits hung down and swayed nicely. Timing it just right I waited until her ass started backwards before I spoke. "Whatcha doing?"

THUMP/"OAPH!" Then her face shot upwards as her ass cheeks shook from the blow against the desk. "TOM! WHAT! OHGOD! I ... OH ... NO!" I had never seen her face turn as bright red as it did just then, her body frozen in place engulfing the entire rubber dick.

I wanted to fuck her so bad just then, but no way did I want to shoot off in less than 5 seconds so I said, "Don't let me stop you! I'll just let you suck me off while you do that. I think that's fair." My hands were undoing my shorts and pushing them down as I spoke.

"No, Tom, please don't ..." she began as I walked towards her. Then her eyes dropped to my cock-tent in my boxers and she let her mouth hang as she stared. "Oh Tom," she said softly. I made a show of it as I pulled my boxer's waist band out and then over my raging hardon. My tip was caught on the cloth and bent down before it sprang free and bobbed powerfully back up towards my abdomen.

I noticed she had sort of leaned forward as I pulled them down, then when my cock came into view her ass pushed back about three inches to fully impale herself again. I don't think she even knew she did that! What she did was gasp, "Oh Tom! You ... that's ... oh gosh ... it's beautiful!"

Kneeling before her I said, "Suck my cock while you fuck yourself." Rebecca never even looked up at me when I said that. Her eyes were locked onto my cock before her face as it bounced and bobbed to my heart beat.

Slowly she pulled forward as her mouth opened and her soft wet lips encircled my bulbous head. Her body paused there as her tongue swirled around my tip, getting to know me better. Then heaven engulfed me as she leaned further forward and sucked my cock to my balls!

"Oh god!" I gasped as my cock disappeared before my eyes! I think my big sis has been using her rubber cock in more than just her pussy! I sure didn't expect her to deep throat me that easily! (Okay, I am certainly smaller than her toy, but luckily I do have over seven inches of hot and hard cock that is thicker than many of the porn guys I see on line.)

"Ummmmmm," she moaned as she inhaled me while pulling just over half way off of her desk cock.

My own groan of, "Shit yes," tried to cover her moan but instead we made harmonic music together. Her arms were shaking as she leaned back and then forwards over and over, fucking herself while sucking me deeply each time. Her eyes remained locked onto my cock between her lips and I could tell she was getting really turned on.

Leaning over her back slightly allowed me to reach under her and gently stroke her clit as she moved back and forth. My first touch made her jump and look up at me with a twist of her head as she moaned loudly. She was close to cumming and I was even closer so I worked her clit trying to let her catch up. I probably didn't need to put in the effort.

"Oh god sis, don't stop! Oh shit, I'm going to cum soon!" I moaned.

"Ummmm hmmmm," she groaned around my shaft as her pussy moved rapidly grinding her ass hard onto her rubber cock! Somehow she managed to work more of the dildo in and out of her pussy even as she took my smaller shaft in and out of her mouth and throat. She started bucking her hips as she continued slamming back and forth while trying to suck my balls dry.

My fingers stayed with her clit even as my hips shoved forward forcing every bit of my cock into her mouth. "Oh god, I'm cumming!" I gasped as my balls boiled over and my first blast shot straight into her stomach.

"Mmmmm hmmmm oahmmm umph, oamph, mmmmm, hmmmm," she moaned around my cock as she came hard and sucked me better than I thought possible. We both bucked and shook powerfully as we came together as one.

She froze with about two inches of my cock in her mouth and about half the dildo in her pussy. I could see her muscles clenching and twitching as she came in waves while my cock pumped three decent sized ropes of cum into her mouth. She swallowed each one down and kept her tongue flicking all around my cock even as she sucked super hard onto me.

And then she moaned in release around me as her body slumped and her orgasm faded away. Every now and then her back would shake in time with another moan as she slowly moved her face on my cock in about two inch motions.

"OH FUCK!" I gasped as her tongue slid around my tip, licking me clean. I couldn't take the incredible sensations she was giving my super sensitive cock so I slumped backwards and sat on my haunches. The moment I left her mouth her head flopped downward and she gasped for breath even as her moans continued softly. She then leaned down and forward onto her elbows until the rubber dildo left her gaping cunt and sprung wildly as it bobbed and weaved for about ten seconds.

"Jesus shit," she moaned as she rolled onto her back and looked up at me. "You came back," she said showing her total grasp of the situation.

"Uhuh."

"Why?"

"To catch you at it," I said softly as my breathing began to slow. She just looked up at me so I went on. "I wanted to fuck you so bad. You don't need that rubber guy anymore!"

"God Tom, you're my brother," she said and I nodded my agreement. "You do taste good though! I never got any taste when I practiced on Ralph, that's what I call it, 'Ralph'. Well, I did taste my pussy but you taste different. Good different. I liked it!"

"Well, you sure got one hell of a load from me! You really made my cock feel good!"

"Thanks, I'm glad I finally got to suck a real one. You've got a nice cock Tom." She slowly moved until she sat close to me. "You know that if we fuck it's incest, right?"

"Yeah, so what? You're on the pill and neither of us has had the opportunity to catch an STD so this should be a win-win situation."

"I can't believe I'm even considering this."

"Oh come on sis, wouldn't you rather have a real, hot dick inside of you instead of that cold rubber thing?" She just sat there chewing her lower lip so I added, "Plus, you won't have to do all the work!"

Her eyes dropped to my cock and she sighed, "My god, you're still hard! How can that be after shooting out the huge load I just swallowed?"

I gave a little chuckle and said, "Like I said, I really want to fuck you! I guess that is proof positive."

Both of us looked at my cock which gave a huge bounce all on its own just to emphasize its agreement with my statement. Rebecca reached out and lightly stroked my cock, her fingers making me shiver from the tantalizing sensations. Her brow scrunched up as if she was deep in thought, then she looked up into my eyes as she gave my cock one last tight squeeze.

"Okay, here's the deal," she said. "I'm willing to let you fuck me once, just because I really want to know what a real cock feels like in my pussy! But I'm not willing to do it more than once."

I readily agreed to that, figuring that 'once' is much better than 'no way'. Besides, I was feeling pretty confident that once she felt me inside of her that she would prefer me to 'Ralph'. At least that's what I hoped would happen. Standing up I reached down and took her hand to help her up. My sister's eyes never left my cock until she was nearly upright. I stepped out of my shorts and boxers then led her the five steps to her bed where I dropped her hand and whipped my T-shirt up and over my head, leaving me just as naked as my older sister.

"Oh god Tom, I am so nervous," she said followed by a quick intake of breath.

"Me too."

"What now?"

"Um ... I think we get on your bed."

"Oh," she said with a soft laugh. "Guess that would help, huh." I watched her gorgeous body move in hesitating fashion. Finally lying on her back with her hands failing in their attempts at modesty she looked at me and blushed deeply again. "Now what?"

Now it was my turn to get timid. I wanted to slam my cock into her pussy so bad, but from the porno flicks I've seen, was I really supposed to go down on her first? Slowly I crawled onto her bed and looked cautiously at her red swollen lips, still showing the effects of 'Ralph'. Trying to get romantic I moved to her face and leaned in for a kiss.

"Oh no you don't! Just because I'm agreeing to let you fuck me once, that doesn't mean we're going to get all mushy here!" she said as she turned her face from me.

Well shit, I need the practice at kissing and now she says 'no'. Not really showing that it bothered me I slid down her body and moved between her legs putting my face about eight inches from her sex. Her hand reached up and pushed against my forehead.

"Really Tom, take a look at Ralph and then tell me that you need to get me turned on." I looked over at the desk with the very robust looking penis hanging out from the side and gasped; it was dripping with her juices!

"My god sis! I hadn't noticed!"

She just sighed as I moved up putting my cock on top of her slit. I moved back and forth a couple of times, feeling my cock get wet from her juices that leaked out of her. My sister reached down and took my cock in her hand then looked into my eyes. "I guess we're really going to do this then."

"Yeah," I answered breathlessly.

"Okay then," she replied as her hand pulled my cock towards her and pushed me into her about three inches. "Oh god! I didn't think it would feel so different!"

My hips pulled back about two inches and then I just shoved forwards, not stopping until my base crushed up onto her engorged clit. I paused there and looked into her eyes, checking to see if she had second thoughts. She just looked enthralled so I pulled back nearly all the way and then slowly shoved my lance completely into her again.

"Ohhhh Tommm," she moaned as I bottomed out again. After counting to five I pulled back and then seamlessly reversed my direction as I pierced her once again, our bodies melding into one. "Don't stop! Ralph doesn't feel like this! Your cock is HOT and he is always cold! And oh gosh, I can feel your heart beating in my pussy! OH STOP! Don't move. Just stay deep inside of me so I can enjoy the feel of you!"

I had never felt anything so awesome in my life! My cock was finally inside of a real live pussy! Keeping my crotch pressed tightly into hers I basked in the unbelievable sensations as her pussy clutched tightly around me, then loosened only to tighten once again. This is SO much better than jacking off!

My sister's voice brought me out of my thoughts, "Wow, I can't believe how good your cock feels inside of me! You aren't even close to being as big as Ralph but you really feel good!" She looked deeply into my eyes and breathed out a soft, "Okay my nasty brother, you can move now. Fuck me. Fuck your big sister!"

"With pleasure, sis." My hips pulled slowly back until my tip was barely inside of her, then reversed and bored into her burying my lance completely. I retraced my movements at the same pace, and then once again. Each time I bottomed out she groaned huskily beneath me.

For several moments I kept up these motions with no variance in length or speed. She felt wonderful. As I pulled back out of her I looked into her eyes and said, "God sis, you are so beautiful!" While I said that last word, my hips powered into her super fast making her gasp.

"OOAPH!" she gasped.

I reared back and slammed into her again ... hard!

"OAFFF! God yes ... fuck me! Oh god don't stop!"

What was she thinking? Stop? Not likely! If I could stay hard I would fuck her for the rest of the day! She had said only this one time so I was going to make the most of it! I leaned my face down and began sucking on and kissing her right nipple, rapidly sending it from pointed to rock hard!

"Oh my goodness ... suck my tits! Harder ... suck them harder! Oh that's good!"

Her legs wrapped around my ass and her fingers gripped my arms tightly while she moaned in pleasure. My mouth moved from one nipple to the other, my fingers working the free one lustily. God her tits are nice! My hips crushed her clit between us and I ground my hips into her while sucking hard on her left nipple, my tongue flicking at it rapidly.

"OH!" she gasped into my ear. Her body jerked violently then and she cried out, "Oh shit! Tom don't ... Ohgoddon'tstop!" Her pussy clamped around my cock super tight as she shook and quaked beneath me. She then moaned long and loud as her body went ballistic while powerful tremors plowed through her being! And then she went limp, her hands falling from my arms and her feet held to my ass only due to the good ankle lock she had created.

I lay there on top of my sister letting the reality of the situation fill my brain. I was fucking my big sister AND I had just made her cum! I made her cum in a big way, too! WOW! With one soft parting suck onto her nipple my head then rose up and I looked into her eyes ... her eyes that were open as slits and looked glazed and unfocused. Striking while the iron was hot I leaned down and gently kissed her, our tongues barely touching through her open lips. Moments later she kissed me back. And then her tongue darted into my mouth as she moaned into my mouth!

My hips resumed moving in and out of her in about three inch motions as our kiss intensified. Every now and then her pussy would grip my shaft tightly as she moaned into my mouth. My thrusts grew to about 5 or 6 inches in length and I was using more forcefulness as her arms moved up and slowly encircled my neck, pulling our lips tighter together. God she felt incredible wrapped around my cock like she was.

"Got damn it Tom," she said with our lips still pressed together, "you weren't supposed to kiss me." Before I could think of a response her tongue shot into my mouth and our kiss morphed into the best one ever on planet Earth! We rocked and rolled sideways as our passion overwhelmed us. Somehow we ended up with me on the bottom. That's when Rebecca pulled her face from mine and then sat upright on me.

She grinned down at me then said softly, "I didn't expect it to be this good! You really made me cum hard! I sure hope you can hang in there with me until I can cum again." Her hips never really stopped moving on me as she rolled them in a circular movement while simultaneously lifting up about five inches before her pussy would suck me right back into her. It felt...beyond any words I can think of!

Instead I grinned back at her and said, "Considering how much jerking off I've been doing thinking about this happening, I'm pretty sure you'll cum again ... and again!" I gave her a hard up thrust each time I said the word 'again'.

"Oh shit Tom, you sure can get me going like that! And I'm glad to know you are so confident but now you just need to prove it!"

I pulled her back down to me and rolled us over taking the top once more. "Okay, you asked for it!" I didn't know for sure what I was going to do, or if I could make good on my boast. What I did know was that my balls belonged to a perpetually horny teen that was living his dream cum true and had no plans to stop soon.

I grabbed her hips and lifted them up as I managed to squat on the bed, her ass supported by my thighs and her legs flopping behind me. I was able to pivot my hips which along with small thrusts gave her g-spot (I could tell when I hit it) powerful stimulations. Each time I rubbed my cock against her special spot she gasped and her legs tensed. Finally she struggled to wrap them around my waist lightly.

About three minutes in that position and I realized her clit was poking right out and looking at me. I had been massaging both of her breasts so I slid my right hand down her body, lightly trailing my fingers over her skin as she stared into my eyes. I barely grazed my fingers over her clit and my sister quickly gasped, "Oh god!"

"Like this?"

My fingers gently rubbed her proud clit and she groaned, "Oh gosh Tom, keep doing that! Oh shit it feels so good! Oh yeah, fuck that cock into me while you rub my clitty."

I just smiled at her and rubbed slightly harder while also giving her little button an occasional gentle pinch between my thumb and fore finger. My movements were really having an effect on my sister even while they allowed my balls to regain some control. I did NOT want to cum too soon! Oh no ... when I finally flooded her pussy I wanted there to be no doubt that she would be begging me to fuck her again!

Her breathing was getting shorter and each time my cock head rubbed past her g-spot she gasped, "Ungh!" or something similar. My fingers continued working over her clit as my hip movements shortened as I concentrated them right in the area of her excitement center! About forty or so "Ungh"s later Rebecca's face turned bright crimson and she cried out, "OH SHIT! Oh god Tom, I'm going to cum! Oh! Oh! FUCK! Yes ... yes ... yes ... yes ... yes ... yes ... oh GOD YES!"

It was difficult to maintain the motions that were pushing her over the edge but somehow I managed. I loved looking down at her face as she strained in ecstasy, her fingers digging deep into my thighs. It wasn't until I knew she was finished with her cum that I eased my fingers away from her throbbing clit and pressed my dick into her and stayed buried there.

Her eyes fluttered and then she looked around as if to find me. They settled on my face and she gave a long satisfied exhale before taking a deep breath. "Wow! That was different! You are really giving Ralph a run for his money. I always get off on him but I've never came so hard as I just did!"

"Thanks."

"Oh no, it's thank YOU little brother! But tell me; is that marvelous cock that is filling me so wondrously ever going to cum again? I mean, I know it can 'cause I swallowed enough of its stuff, but a girl starts to wonder after a while if she can't get the guy off."

"No worries, sis. I'll pump your pussy so full you'll think I came by the gallon! Just not yet, as I plan to enjoy our one time to the max!"

"Wellllll ... maybe I was a little hasty about that one time thing." She looked down to where our bodies merged into one and shuddered then grinned up at me again. "Maybe we can work something out that both of us will like!"

"Now you're talking sis!" I said as I got her to loosen her legs around me so I could change positions. I moved onto my knees and placed her calves on my shoulders as my shaft gave her a nearly full length thrust. "Damn you are tight!" I said in a near growl.

"Imagine that! And that's after being stuffed with my buddy Ralph!"

I laughed at that and gave her a real hard thrust to emphasize my thoughts as I said, "I wish you'd stop comparing me to Mr. Rubber Man! I mean, he came from a different mold than I did!"

"Haha, yes he did!" she laughed back at me. "But I like the way you turned out ... ooof! Oh yeah, I really like the way you turned out. Now shut up and fuck me ... please little brother?!"

"I'm not THAT little, but okay."

"No you aren't! Oh gosh that feels good! I love the way I can feel you cock twitch inside of me. And it's so hot! God I love that! Ralph never gets warm, damn him! Ooooh yeah, keep fucking me like that; nice and deep!"

So I did. I was giving her the full stroke, pulling out until my tip was barely inside of her and then slamming it deeply into her making her body shake from the thrust. Our skin smacking together was getting pretty loud making me really glad we were alone.

"Kiss me bro," she said with a pleading look.

So I grabbed her ankles from above my shoulders and pressed her legs forwards and down until her feet were on the bed up past her head, her knees by her ears. Each of us groaned in pleasure as I leaned down and kissed her, our tongues dancing lustily together from mouth to mouth. I began moving faster into her in this position. Rebecca's arms wrapped around my neck as her moans of joy increased wondrously.

Probably four or five minutes later she grabbed my head and pushed me back a few inches. "You're hitting my spots just right, Tom. Keep this up and I'm going to cum again! Give it to me this time! I want to feel you shoot your stuff inside of me! Make my day and pump me full!"

"I like that idea," I said as I stepped up my efforts just a bit more. Her breathing was getting wild, holding it briefly and then gasping hard and fast. My balls were rolling in their sack as my pleasure rose to new heights. I could tell I was nearly there and I groaned, "Oh shit sis, I'm going to cum!"

"DO IT!"

"Fuck yeah; I'm going to cum inside of you!"

"Oh Tom ... I'm cumming again! Fuck me! Fill me! Oh my god this is ... OHFUCK!" Rebecca choked on her breath then as her pussy went into spasms around my pounding cock. My first blast of hot cum shot into her and she screamed, "Oh fuck MEEE!" Her hands quickly moved to my ass cheeks and she kept pulling onto me hard trying to drive me into her with even more force.

We rutted there, each of us cumming harder than ever as our climaxes merged into one incredible orgasm for the ages! Every few seconds my hips would jerk back and then SLAM back into her crushing my base against her agonizing clit, making her cum even harder as my shaft spewed out more steaming baby batter! And then, finally, we were spent. I stopped with my shaft as deep inside of her as humanly possible, her hands holding tight to my ass to make sure I stayed there.

As we each recovered from ecstasy my body slowly slumped down onto her as if I wanted to crush her with my weight. After lying on top of her for a few seconds I started to lift off of her but she gripped my ass tighter as she said breathlessly, "No ... don't go! Stay like this, I want to feel your weight on me as your cock throbs and pulses inside of me. God that is so sexy! I've never felt a cock throb in me before!"

"Really?" I said into her hair as I lay on top of her head to head. She just nodded her head. "Wow, I'm glad, actually thrilled to have been your first!"

"Yeah, me too. I was pissed at you for forcing me to fuck you, but right now I am SO glad we did. I can't think of a better first time!"

"You mean ..."

"That's right Tom, yours was my first real live cock!" She turned her head and I turned mine as we looked into each others eyes from about six inches. "Just so you know for sure, you really fucked me good! I love your cock bro, and that is something I never thought I would ever say!"

"Wow sis, I am so glad you said that! I wanted it to be good for both of us. If I hadn't had you suck me off first I would have popped in about half a minute!"

"That would have sucked!"

I laughed and grinned at her as I said, "Yeah, for sure! Luckily you sucked first by swallowing my load ..."

"It tasted so yummy!"

"Thanks. But that really helped me to hang in for the long haul! God damn your pussy feels so good and ... TIGHT!" I grimaced as she really squeezed down around me just then.

"I guess all that practice at clamping down onto Ralph comes in handy! Many times I have squeezed him so hard that I can't move on him."

"Okay, enough of the rubber man comparisons. We need to shower. Would you care to join me, sis?"

"Second best offer I've had today!" she said as we untangled and eased off the bed.

Once the water was up to temp I followed Rebecca into the shower and we took turns getting wet. I reached for the soap only to be stopped by my sister as she molded her body into mine. We just stood there holding each other with our bodies so tight together that the water couldn't squeeze between us. Her tits felt so nice pressed against my chest as my hands toured her sexy ass cheeks. Our simple moment ended when she turned her face and kissed my chest softly.

We eased apart a bit and she looked up into my eyes. "You ... you don't hate me for using Ralph, do you?"

"Hate you?" I said in surprise. "No way! First of all, I've been jerking off for years so who am I to judge? Secondly, Ralph did help get us together so I'm kinda glad you had him!"

"Really?"

"Really, really!"

"Good! Now I'll wash you while you wash me."

So that was the plan and we started out innocently enough. But then I got delayed while 'cleaning' her incredible tits! I was mesmerized by just how supple they felt to my fingers and how hard and pointy her nipples could become. Rebecca cooed with pleasure while her fingers found and worked over my half hard cock. Well, after several moments of her gentle touch my shaft became a stalagmite as it strained to reach the ceiling.

"God you are so hard again," she gasped with a horny grin.

"I think that is all your doings, sis. But, now that I'm up again, what do you say, we're two-thirds of the way around the world, shall we finish the trip?"

"You really want to fuck my ass?"

"Hell yeah! Besides, we're in the perfect place for cleanup afterwards."

"True ..." she said as her fingers slid silkily over my lance. "Okay, just be gentle, I've only had Ralph in there once and he hurt like hell."

"I will be." I grabbed her conditioner and coated the end of my cock before pouring some onto the crack of her ass while sis bent over facing away from me. "Spread your cheeks sis," I said as I grabbed my rock hard cock and slid it up and down her ass crack to really coat my tip with the slippery liquid.

She did and I pushed my tip gently yet firmly against her puckered opening. She moaned with each push while I groaned along with her. On the third try she gasped as my cock head slid past her ring where I stopped instantly. She was gasping rapidly while I massaged her lower back and asked if she was okay. She just nodded her head and pushed back at me with her ass.

We worked together until after about three minutes of slow insertions my pubic bone bumped her ass and my balls rolled onto her pussy lips. "Stay like that Tom, give me a moment to get used to you in there."

So I did just that, my hands stroking her back, ass and upper thighs. I leaned over her and kissed her on the back while my right hand found her clit and gently stroked her there. "Oh god Tom, I'm so turned on! Start slowly but please fuck me. Fuck my ass! Oh god I want to feel you pumping my ass full of your hot cum!"

Starting with short inch or so long movements I began thrusting my cock in and out of her super hot ass while she moaned with my moans. After a few minutes my cock was stroking in to her in six inch motions and her moans were now lusty gurgles as her excitement grew. She moved her hands from her knees to the wall for support as I was really driving into her now.

Her head turned back to look at me and she gasped, "God Tom, my body is on fire with lust for you! Fuck my ass hard ... no, harder! Yes, like that! Oh my god I'm going to cum real soon!"

When she said that I knew she meant it as her sphincter had really clamped onto me increasing my pleasure immensely. Her tightness was rapidly pushing me towards my own climax so I grabbed her left tit for leverage while my right hand stepped up its efforts on her throbbing clit.

"OH god it's SO good!" she cried out.

"Oh sis!"

"Fuck me! Fuck my ass and fill it with cum!"

"Oh lord I'm getting so close!"

"Give it to me!"

"Close now!"

"Fuck me!"

"So close!"

"Shoot me full!" she screamed. "Oh god I can feel you getting bigger!"

"Oh SIS!!!"

"YESSSSSSSSSSS!" she screamed as my first blast of hot cream shot deeply into her bowels, making her nearly collapse from the pleasure. My hands held her up till she could keep herself upright, even as we both pounded our bodies against the other's. I pumped her full with several steaming hot ropes of cum while her ass milked me for all I was worth.

Each of our incredible climaxes ended nearly in unison, letting us stand there connected carnally as we gasped for air. Slowly she pushed herself upright and twisted her body at her waist as I held her ass tight against me. She looked back at me with a satisfied look and said, "God you are so much better than Ralph! You made me cum so hard Tom ... I love you!" She kissed me then, her tongue searching out mine and then dancing with it from mouth to mouth.

We stood like that, kissing all the while, until my flagging shaft slithered out of her ass with a weird slushy plopping sound. "Oh shoot, you're gone! I liked the way you fill my ass so full."

I turned her around and hugged her tight as I said, "It will be my pleasure to fuck your sexy ass any time you want!"

She giggled and said, "What a nice thing to say! But the water is getting cold so let's hurry up and get out of here."

She was right about that so we each washed ourselves off -- it was faster -- and then got out and dried each other off. Once dry she wrapped her arms around my neck and rose up onto her tiptoes to get nearly nose to nose with me. "Tell you what Tom, the only way you will hear that thumping noise from now on is if you aren't taking good enough care of me! And I warn you, I'm pretty horny most of the time!"

"Unless you are hinting at right now, I think I can handle that request!"

"Now?!" she said with a soft laugh. "No way brother dear, you've fucked me quite well, thank you! What I need now is a nice nap." I nodded my agreement and headed to her room when she said, "Uh, uh, uhn, alone Tom! We don't need to get caught in bed together!"

"Yeah, you're right. I'll see you later."

I flopped onto my bed and was soon drifting off to sleep, smiling at myself at how well my plan had worked. One thing was certain, my hand, like Ralph, was going to get used a lot less often, if at all!
