I Hate My Sister: The Se-Prequel
 
 
After my first experience being used as Jenna’s toy, she showed no hesitation in taking full advantage of the situation. It was only two days after I’d experienced how deep she could stuff me up her crapper, and I’d only just managed to finally scrub away the smell. I’d gone to bed unusually early, still needing to catch up on my rest after spending an entire night squeezed in her guts. I’d started to doze off, when I heard my door open. I feel something push on my bed as I slowly open my bleary eyes, but I snap fully awake when I see the cause of the sound.
 
 
Jenna has let herself into my room, and is currently sitting next to me on the bed, completely naked. I spent a moment staring at her, as I had not yet gotten used to seeing my sister’s increasingly large boobs without a shirt. Evidently, she had given up any sense of modesty around me now that I’d had a tour of her insides. Enjoying the attention, she squished her boobs together, teasing me as her ever-present smirk got even wider. “Perfect, you’re awake, I need your help.” she said, ignoring the fact that she’d just woken me up. I look more closely at her face, and realize she looks the same as a few days ago, when I thought she was sick. Her face is red with a deep blush and small beads of sweat forming, and her breathing is a little ragged. I’m pretty sure I can guess why she’s here in one try.
 
 
“I was in my room doing….stuff…. and I started thinking about the other night.” Later in life, I would wonder why she even bothered to censor herself talking about masturbating, considering she had no problem having me help her do it. “It felt amazing when you got pulled into my butt, I never had any idea that I could do something like that. So that got me thinking about all the possibilities.” She looked at me with a hungry look in her eyes, and I knew that I probably wouldn’t like any of the ‘possibilities’ she had in mind.
 
 
Unable to hold herself back any longer, she pulls my blanket off of me, and swings one of her legs over me. Straddling my face, I am momentarily given an up close view of my sister’s horny ass once again. Her pussy is already dripping wet, causing little splatters to fall onto my face. The moment is short lived, as she sits down on me, hard. She begins grinding my face into her loins, as she explains “I have lots of ideas for fun things we can do together, but I thought I’d start by seeing how good this felt.” As she says this, her pussy slowly accepts more and more of my head as she forcibly squishes me into it, until with a wet SCHLUP, my head slips entirely inside her soaking folds.
 
 
“Oooooh… fuck yeah…” She says in a slow, drawn out voice, drooling very slightly. “I figured if I could fit you in my ass and it felt that good, I just had to see how it felt to have you in my cunt.” She bounces up and down on my neck a few times before laying back, my body sticking out beneath hers like some sort of humanoid millipede, with both of us on our backs. On the inside, the experience was thankfully less disgusting than being in her ass, if only just. The smell is much more tolerable, a mixture of sweaty and syrupy; a little bit salty, sweet, and sour all at once. The taste was the same, but overwhelmingly more potent. It might have been a slightly easier fit than being in her ass, but the walls of her pussy squeezed and clenched around me far harder. Over the constant squelching sound from her sliding up and down my head, I could hear her heartbeat, her labored breathing, and the occasional squeak or quiet moan slipping out. She was trying her best to keep quiet, as loud sex noises coming from my bedroom would have certainly drawn our parents attention.
 
 
“Oh man, I wonder how deep I can fit you this time. Ready to go spelunking in your sweet sister’s coochie?” She says as she hooks her feet under my arms to pull me in. As my shoulders slide inside, she bites her lip to stop from squealing with ecstasy. With the hard part over and a good grip on my upper body, she was free to enjoy herself and let her pussy do the rest of the work. Rubbing her clit with one hand, and teasing her nipple with the other, Jenna was in heaven. Inside her pussy wasn’t the hell that her shitpipe was, but it was no walk in the park either. Her pussy rhythmically clenched and released, sucking my deeper into the musky depths. I could feel her traveling down my chest, her thighs intermittently pressing together into me to aid my descent. Compared to the sweltering heat inside her, my feet felt like they were inside a freezer, and for a moment my exhausted mind almost couldn’t tell which direction I wanted to go anymore.
 
 
Reaching my waist, Jenna’s hips swallowed mine easily, leaving only my legs outside her desperately horny snatch. Panting, she looked down to check on her progress. She couldn’t see my legs over her overfilled, squirming belly, which she rubbed lovingly. “You know, lots of guys my age would probably be so jealous of you right now. They’d kill to get action like this. Maybe when you’re older you’ll learn to enjoy playing with me.” She says, grinning, as I squirm a bit harder in a futile attempt at protest. In the days since I’d seen the inside of her butt, I did some research on sex (looked at porn) to try to understand, and I didn’t think she was right. Years later, I know I was correct, though she was half right: I did eventually get pretty used to it.
 
 
“I don’t think I can contain myself much longer, and I want to contain you much longer, so how about we take this party somewhere a bit more comfortable?” She pretends to ask me, as she stands up with the bed, my legs hanging out behind her like a set of tails. She opens my bedroom door a crack, checking that our parents aren’t around, before quickly running next door to her own room, hoping she wouldn’t leave a trail of drips on her way. Closing the door, she presses the lock in with a click, ensuring that her fun wouldn’t be interrupted. Safely in her room, she no longer had to worry about making noise, as she could care less if our parents knew she was fucking herself. Our parents used to be hippies, and let us do basically whatever we wanted, within reason. If their teenage daughter wanted to experiment with touching herself, or smoking some weed, better that she does it safely under their roof than looking for it elsewhere.
 
 
Jenna walks over to her bed, and props my legs against it. She begins bouncing on my legs like a dildo, moaning happily and descending a little further with each bounce, until she’s sitting on her bed. My feet were still sticking out beneath her, but I was otherwise completely concealed within my sister’s greedy snatch. Laying back into her bed, she reaches down to start playing with herself, when her eye’s light up with inspiration. With a lusty grin, she instead begins tickling my feet, knowing that I’m extremely ticklish. I redouble my efforts squirming, trying desperately to escape the hand mercilessly tickling me, which was exactly what she had wanted. The feeling of me wriggling, trapped between her legs, was far better than anything she’d ever been able to do herself. I was practically drowning inside her, femcum filling nearly all of the space inside her that was not being occupied by me. She was getting close to finishing, evident by the increasing pace of her clenches that were nearly crushing me.
 
 
Finally, with a loud, relieved moan and the strongest clench yet, Jenna reached climax, sucking my feet inside as the ocean of fluid I was soaking in flooded out of her. Her bed now soaked, Jenna didn’t seem to even notice. She just lays in the wet sheets, undisturbed, as I was completely sealed inside her temporarily satisfied snatch. I start poking at the walls with my finger, trying to prod her to hurry up and let me out.
 
 
“Zzzzzzz…..” I could hear all around me: Jenna had immediately fallen asleep after cumming, and had begun snoring lightly. She grinned happily in her sleep, a line of drool running down her cheek. Frustrated, I think “Seriously, again?!”, knowing that I would be once again spending the night locked within my sisters squishy, dank nethers.
