My Sister's Lotion Pt. 01

*****

High school was difficult for me. Not because I had issues with grades or anything, but because my sister was a grade-A fucking bitch. She found ways to tap into some of my deepest and most fragile insecurities and basically rip my self image to shreds. My virginity and my complexion where her two favorites. What made it worse is that she was also a grade-A fucking bombshell. It's one thing to get degraded and talked down to by a sibling, but it's worse if that sibling is basically the hottest creature on the planet.

Jenn's body was ridiculous, and I hated it. Her features were wonderfully disproportionate. She had immense DDD breasts that stretched her tight-fitting attire to max capacity and a midsection that didn't look like it should be able to support them. She would wear sports bras and skin-tight t-shirts around the house like a slut and let her cleavage just bounce and jiggle around in front of me and dad on a daily basis. I caught dad adjust himself on a few occasions as she bounced through the house or up/down the stairs. She had an ass to match too. Her big, juicy cheeks looked like they were being held up by a shelf when she wore her yoga pants. She knew she was hot and she was a total bitch about it, teasing me and belittling me at every opportunity.

I wasn't bad looking myself. I had a decent muscle structure and average looks, but I had sort of a nerdy presence and hanged out with the computer geek group at school. My complexion and lacking social skills didn't help my popularity either.

I had a big dick though. I didn't have much to actually compare myself to, except for the monstrous volumes of porn I watched in those days. There were very few studs in porn that had me beat. I also had a load that was on average 3 times larger than these jack offs in porn. The money shots in porn always left something to be desired when compared to my own.

I had taken a beating that year in semester exams. I passed everything, but it was brutal. I was not in the mood for any tom-fuckery from my sister Jenn, but as you can guess, that's the day this story is set in. I had barely even walked in the door when the berating began...

"Hey kitchen bitch, Sam left you a gift in front of the dishwasher and dad wants you to clean it up" Jenn lazily demanded from the couch with her back to me. Sam was our Boston Terrier puppy that Jenn just had to have despite her inability to show affection for anything but herself. I glanced over and sure enough, there was a nicely sized dog gift for me right on the floor. I looked over at dad who was sitting in the recliner catty-cornered from Jenn and opened my mouth to begin protesting. Dad gave me a slightly apologetic look and shrugged a bit. She could get anything she wanted from any man, dad or otherwise. He probably planned to go jerk off to her later and didn't want her to get an attitude with him.

I sloughed off my backpack and shoes in the entry hall and set about the task.

"Bet you failed your exams, huh?" Jenn yelled from the living room.

"Hey fuck off dude, I'm over here cleaning up after your dog and-"

"Relax Jack!" My dad barked at me.

I angrily completed my task, stood up and glared at dad. He was idly sneaking glances at Jenn's tits as if it was nothing. I stomped into the living room angrily. Sure enough, Jenn was wearing a cut-off white T with no bra on, cloth stretched to maximum capacity and barely confining it's contents. Her nipples were hard and clearly visible through the thin fabric, threatening to tear holes through it if they got any harder. She was very focused on filing her fingernails with short rapid strokes which caused her generous tit cleavage to bounce side-to-side gently. I was ready to stomp into the living room and fire off a series of rapid retorts at her, but I lost my voice at the sight.

"What the fuck are you doing faggot?" She looked up and shot at me, "Go play your stupid video games or watch porn or whatever the fuck you do".

"You know what Jenn, you're a fucking cunt."

"Jack..." Dad snapped out of his daze and said my name with his fatherly warning tone. But I wasn't backing down this time.

"No dad. She needs to know." I focused my attention back on Jenn "You better start treating people with some respect or one day someone is going to teach you a lesson you won't forget."

"Oh yeah is that so?" She mocked. "What are they gonna do, huh?"

"You'll see, bitch" I fired at her before stomping away.

Dad began a lecture about my language which I drowned out as I headed up to my room. I wished it could be me that taught her a lesson. I wished I could be the one to break that stupid, slutty bitch. Just as I felt I was about to chip a tooth from gritting them so hard, I walked by her bathroom. Her stupid cunty bathroom with her pink shower curtain and fluffy toilet cover and her assortment of fruity lotion-

I stopped in my tracks. Her fruity lotion bottles. Her stupid fucking cunty pink and purple, overpriced lotion bottles. I had an idea. I looked around, glanced down the stairs to make sure I was in the clear and slipped quietly into the bathroom. I looked around for what I thought would be the most expensive or most used bottle and decided on a small plastic container with an artfully painted label about the size of a hotel shampoo bottle. Usually the ones that come in small quantities are more expensive, I thought to myself. I silently slipped it from it's resting place in the front of the others and tip-toed back into my room, quietly shutting and locking my door behind me.

The plan was a glorious one. It was vile and abhorrent, but also ingenious and savage. The bottle was about halfway full, but it needed to look like there was about the same volume in it as before, so I squirted some out onto my hand and placed the bottle on my desk. I used my other hand to unzip my jeans and pull them down along with my boxers. I deftly navigated to my favorite porn site with my hand shaking in anticipation and found a suitable video.

'She's so fucked', I thought to myself. 'This will teach that stupid bitch'

I went to one of my standard videos and hit play. It was a curvy dark-headed slut that loved gobbling on big dicks. I'll spare time describing her by simply saying she was built pretty much like my sister. Looked a bit like her too... Coincidence of course though. She was on her knees, pretending to clean something off the floor when her supposed brother walks in, sits down in front of her and idly begins talking to her. After a few moments of this, one of her large tits falls from the top of her very low-cut t-shirt, bouncing into her brother's view and pretends not to notice. She continues to clean the floor like the good slut she is while her huge, creamy tit lazily bounces back and forth in front of her brother. He quietly adjusts his hardening cock in his pants as his eyes lock onto his sister's naked tit. Just as he gets his cock in a comfortable position, her other tit falls out of her top and both of her tits are in clear view. Her brother's cock looks as if it's about to simply rip right through the zipper when she speaks.

"Just take it out dude. No need to be in pain."

He lets a slight gasp at realizing he's been caught, but quickly resigns himself to the task. It did look very uncomfortable. After a moment of hesitation, he throws the zipper down and his cock comes bounding into view. His sister sits up and pushes her chest out for him, giving her brother a full frontal view of her massive tits. They both sit silently for a moment, eyes on each others exposed parts, when she reaches down for the sponge she was cleaning with. She holds it above her chest with both hands and squeezes it, sending milky soap-water cascading luxuriously across her magnificent globes. The brother can't take it anymore and tentatively wraps his hands around his cock, sending a big drop of precum oozing from the slit and down the shaft.

That was about the time I reached down with my hand, covered in my sister's face lotion, and glided the offering across my shaft. Once it was completely coated, I wrapped my fingers around my tool and started to slowly slide my slick hand up and down in agonizingly slow strokes, just as the brother in the video was doing.

The sister began using her hands to massage the frothy liquid into her tits, slick flesh oozing from between her fingers as she gripped her breasts firmly. Precum was virtually pouring from the brothers and my cock together in anticipation for the load to precede. This video usually did the trick for me pretty quickly, so I glanced over at my desk to make sure the bottle was within reach.

The sister inched toward her brother on her knees across the tile floor as she continued fondling her copious tit flesh, slick and shiny with soapy water. She stopped with her face inches from her brothers cock and breathed warm breath across the head, fresh flows of precum bubbling from his tip and mine alike. She tortured him for only a few moments before sticking out her tongue and just touching the very tip against the underside of his head and swirling it seductively through the river of precum running from the tip.

That was all it took. The thought of doing something so fucked up to my sister and acquiring silent and unknown victory over her only served to magnify the moment. I stood up, grabbed the bottle and lined it up with my cock-head. My knees buckled slightly as my orgasm ripped through me but I kept the bottle lined up perfectly. I didn't want to fuck this up. The first jet squirted so hard from my cock, it threatened to blast the bottle right from my fingers. I gripped tighter and began unloading stream after stream of creamy cock juice into her precious overpriced lotion bottle. I briefly pictured her rubbing my thick cum into her face later that night and additional shock waves of orgasmic bliss surged through me at the thought, nearly filling the bottle completely.

I breathed deeply, catching my breath, and stumbled back into my chair, placing the bottle back onto my desk. I reflected on what I had just done. Would this really work? Does she even use this one anymore? There were so many in her bathroom, I thought to myself. She's quite obsessive over her complexion and has both a morning and evening routine consisting of several lotions and toners. I capped off the bottle and shook it vigorously, attempting to mix the remaining lotion with my freshly deposited cum. The bottle was warm and I could feel the thick, viscous fluid sloshing around in the bottle. I had already felt victorious, maybe simply for coming up with such a perfectly fucked up plan for such a fucked up cunt.

Once I believed the liquid to be sufficiently mixed, I shuffled back to my door and poked my head out, checking the coast. It was clear. I silently popped back into her bathroom, checking my back constantly, and placed the bottle back in it's exact same location with the label facing the same way. There was clearly more volume in the bottle, but I wasn't too worried. She was too stupid to notice, I decided. I bolted back to my room on tip-toes and shut the door behind me, silently fist-pumping to myself in victory now that the deed was complete.

The next morning was the first day of holiday vacation. I slept in and got one of the best rests of my life. I felt as though a weight was lifted from my shoulders. As if I was finally on equal footing with my sister. I almost held no ill will toward her at that exact moment. I slinked down the hall past her bathroom and peeked in. She was standing in front of her mirror, back toward the door wearing a tight white tank top. Her big, round ass clad only in a tight pair of pink and lacy underwear, jiggling slightly as she brushed her teeth. I adjusted my slightly stiffening cock in my boxers and continued on down the hall.

After a fairly quick breakfast and some idle chatter with the parental units, I made my way back up to my room to plan out my first day of vacation. I stopped again at her bathroom to take another incestuous perv at my sister before retreating to my room. The door was cracked slightly, I peeked in but she was in the shower. I glanced at the spot "the bottle" was resting the evening before and to my great satisfaction, it had been moved a few inches to the left and, whether in my imagination or not, a small amount of the fluid appeared to be missing. I relished at the thought. I shuffled back into my room and shut the door behind me.

'Had she used it?' I began thinking to myself. 'Had she rubbed my cum into her hands? Her arms? Did she rub her own brother's cum into her face?' I silently rejoiced. 'I bet she rubbed her brothers cum into her face and probably her tits too'. My mind began to get creative. 'I bet she slid her little cum-slick hands all over those big tits, coating them in her own brother's creamy cum. That disgusting cunt. I bet she moaned out when her fingers slid over her big hard nipples and down into her copious cleavage valley.'

I was giddy at the thought. That dumb slut.

I had finally gotten the satisfaction that I so badly needed. Her bitchy passive-aggressiveness stopped bothering me essentially completely, and I felt I had a newfound sense of confidence around her and her terrible attitude. I also noticed her precious little lotion bottle decreasing in volume on a nearly day-to-day basis. I must have chosen the right bottle.

Unfortunately, this was causing a somewhat negative side effect. I couldn't stop imagining her rubbing my cum on her body, and I couldn't stop jerking off thinking about it. It was a nearly nightly routine. She always closed her door before she began her evening moisturizing ritual, so I knew when to get started. I'd lay down in my bed, which shared a wall with her bathroom, and push my ear to it, partially in an attempt to catch any audible evidence of her rubbing the "lotion" on her body, but mainly just to feel closer to her naked body. Occasionally I could hear a slight slapping noise here and there, and to my imagination it could have been caused by any number of things, all of which were disgustingly incestuous and orgasm inducing. Surely it was one cum-covered tit slapping against her tight stomach as she released it from cum-slippery hands. I regularly released unseemly amounts of cum in white hot streaks up my chest and stomach on those evenings, basking in my disgusting disrespect for my sister and the images of her cum-covered body.

This went on for about a week, and I gotta say, I think her skin looked smoother and more glowy than ever. Gradually though, the bottle became more and more empty until there was none left. I continued to grab glances into her bathroom, either to look at her juicy ass clad in tight underwear or yoga pants and jerk off at the images later, or to check on the status of "the bottle"s contents to see when my sick experiment would be over. On one of such occasions I was disheartened to discover the bottle gone from its place as I headed up to my room one day. She was nowhere to be found, so I glanced around the bathroom to check for it's existence before completely giving up the fantasy. I couldn't find it. I sigh disappointingly to myself as I concluded that my fucked up little project was over. I did relish in the thought that she had rubbed an entire two ounce bottle of my cum into her skin though, and I didn't see any reason why my evening sessions against the wall had to come to an end.

With head down, I ambled back to my room and flopped into my computer chair, ready to dive into some gaming. I looked down at my keyboard and was astonished to find the bottle sitting there. The same bottle I unloaded ounces of cum into weeks ago and the same bottle I spied sitting in my sister's bathroom in the interim.

'What the fuck...' I thought to myself in slight panic. 'Who the fuck-... How did that-... Am I caught?

My mind reeled. did she know what I did? She had to know I fucked with the bottle somehow, otherwise why would she put it in my room. And why did she wait to put it there until it was empty? A million questions raced through my head, but I finally had to settle on one. The most obvious one. She wanted me to refill it. Surely she didn't know what I put in it, she just liked what it did to her skin and she somehow knew I tampered with the contents. I supposed she did detect it became magically refilled that night and put two and two together. I devilishly imagined she knew full and well that I was filling it with my cum, but it was obvious she didn't know. How could she... Supid bitch... She doesn't even realize what she's doing. She's asking her brother to provide a bottle of his cum so she can rub it all over her beautiful body. Just the brief thought sent blood coursing to my cock. What a stupid cunt... The corners of my mouth curled up into an evil smile. I fished my stiffening cock out of my shorts and wrapped my warm hand around it.

'That stupid bitch wants a fresh dose of her brothers cum so she can dump it on face and titties? Well I can provide that.' I deviously thought to myself.

The images of my naked sister leaning her head back in the bathroom and pouring cum down her face and body invaded my mind. It thickly poured from the mouth of the bottle across her beautiful face, down her luscious lips and off her chin, spatting audibly onto her heaving tits. Her other hand reaching up to glide the liquid across her slick chest, grabbing her tits to push them together as more and more of the viscous liquid dripped down and ran through her cum-slick cleavage. In my mind, I saw the head of my cock poke out between her tits at the top of her flesh valley as my shaft was completely enveloped in her wet breasts. My own cum ran down across my cock and lubricated it as I slowly pumped it in and out of her slick cleavage. She looked down and opened her cum-covered mouth as the engorged head of my throbbing cock slipped past her lips and across her tongue. She suckled lightly at the tip and my cock began rapidly spurting streams of cum straight into her mouth. Thankfully I had the bottle lined up in time. I moaned lightly as my cum squirted over and over into the bottle. The images of my sister taking my over-sized load down her throat served to lengthen my orgasm until my legs were quivering and the bottle was overflowing onto my computer chair.

"Fuck yeah, Jenn. Is that what you want? You want a nice warm load of your brother's cum?" I said to myself quietly. "You're gonna rub this all over yourself aren't you, you stupid fuck."

My thoughts about my beautiful sister were so vile. Being able to degrade her so much in my mind did wonders for our relationship.

I didn't need to shake the bottle this time. There was no lotion left, it was nothing but my thick, translucent jizz. I spun the lid on and crept back to her bathroom. I popped my head out my door. Coast was clear. I slipped back into her bathroom and replaced the bottle in the exact location as before. Label away so she could see that I filled the bottle up perfectly to the rim for her. I sneaked back out and back to my room. How dumb could that bitch be?

The next couple of days went by as expected, but lately my sexual thoughts were nearly completely consumed with my sister. Every time she walked through the house braless in tight-fitted clothing, I nearly lost it. Sometimes when I walked by her bathroom in the morning while she was getting ready, I was nearly consumed with the thought of squeezing those juicy ass cheeks, so teasingly stretching out her thin and lacy underwear nearly to transparency. I wondered if she rubbed my cum into her ass as well. I wondered what my cock would feel like smothered between those gorgeous orbs of flesh. My "sessions" were completely focused on the thoughts. I could have filled up 10 bottles for her, with cum that she silently and unknowingly coaxed right from my cock herself simply by her presence.
