My 10″cock was now fully erect. Once again, Jenna was impressed. She could barely get her fingers all the way around it; she let it go and breathed, ‘Whoah.’ Then suddenly, I felt her lips on the head. They were warm and incredibly soft. She repeatedly kissed my cock head gently and softly. Next, she began licking it up and down, pausing to smooch my balls with long, wet, sucking kisses. It felt exquisite. Finally she lifted the head away from my stomach and slipped it into her mouth. She wasn’t as good as Jill was at sucking cock (she needed practice with her teeth) but it was still fantastic. I was so big and her mouth so small that she gave very noisy head.
Slurping and sucking noises filled the tv room. She began a series of ultra sexy (but very quiet) moans and groans while she continued sucking me; I saw by the position af her arm that she was playing with herself again. ‘Mmm, mmm, mmm…’ My cock slipped from her lips to allow her to catch her breath, give her jaw a break and concentrate on her cunt for a bit. She panted in barely controlled lust. Then she was down on it again.
Absolute heaven. Soon she was fingering herself so furiously that she temporarily lost control of herself. Her sucking became more forceful; her moaning became loud grunting. She must have caught herself just then; for she stopped everything suddenly and disappeared from my secret line of sight. I lay motionless, hard on aching and head spinning. Damn. She must have felt she went too far and decided to quit while she was ahead. I’d have to finish this myself after she went upstairs to sleep. Oh, well, at least I’ll have the memory of my lovely young sister blowing me while she played with her pussy to aid me in jerking off.
She was still in the room; I could hear her heavy breathing, though I couldn’t see her. Had to keep up the illusion that I was out cold. I lay in the darkened room, fully exposed and waiting for whatever might come next. Then I heard her approach the couch again. With eyes closed, I thought I felt her place her elbows on either side of my hips, so she could position herself between my slightly spread legs and suck me straight on. Then I felt her lips on my cockhead again….but it was very different….as she inched my dick into her mouth I slowly realized that it wasn’t her mouth at all…my cock was sliding into Jenna’s hot, wet cunt!!
My eyes immediately popped open. I saw Jenna squatting above my crotch, totally nude, one hand on the back of the couch and one holding my pecker steady as she eased herself down onto it, slowly bending her knees at my sides. After the initial penetration, she slid down the full length of my steel-hard 10 inches effortlessly. It was a very snug fit; she was red hot and dripping wet. I felt the tip of my cock find the end of her wonderful wet hole; if she wasn’t so wet, we might never have fit together as she was such a small petite girl and my erect dick was pretty damn big. In fact, at that exact moment, it never felt bigger.
In shock, I looked down at her, fully expecting us to be looking each other in the eye and finally dealing with the reality of what was going on. But all I could see was the top of her head as she looked down at our genitals as mine disappeared into hers. Her short blonde hair almost grazed my chest as she watched the penetration. Her little teenage cunt gripped my cock tightly, especially the muscles just inside her lips. Still looking down at our connecting groins, she slowly and carefully started moving her hips, resulting in a very slight inch-deep fuck-motion.
It was probably all she could take of my massive dick. She raised her head up towards the ceiling and I awaited eye contact once again…but her eyes were squeezed shut as she arched her back in pleasure. She was obviously convinced that I wouldn’t wake up. Now her sweet little titties were staring me right in the face; 2 erect nipples poked out of the small but perfect mounds and begged to be bit and sucked. But I resisted. She was lost in a haze of lust and desire and was concentrating on the feeling between her legs. I felt that if I shocked her out of this, it would end. And stopping my hot teenage sister from fucking me was the last thing I wanted to do.
Jenna had increased the length of her hip strokes. We were almost at the point of really fucking. She brought her head up again and I quickly went to sleep…She was still holding herself over me on her bent knees, arm on the back of the couch, never really coming down all the way; her ass hovered inches off of my balls with her every downstroke. Eventually she increased her fucking until most of my big dick was swallowed up into her sopping pussy with each stroke. She could take the whole thing in with ease now.
My hips started moving; the pleasure I was feeling was too much to ignore. She felt me moving with her and put her hands on my chest. She transferred her weight from her knees and arm onto my body. Our pubic hair finally met, grinding together as we fucked. It was glorious. My hands found her ass and helped her up and down. She started making noise again and looked up into my eyes…I looked straight back. No more secrets. The look that immediately appeared on her face was strange; a mix of great pleasure and kind of a pleading… She kissed me on the lips and quickly blurted out, ‘Please don’t stop Andy. Please don’t stop. Just fuck me it’ll be OK just keep…fucking…me…’ I smiled back at her and said ‘Jenna…You’re so fucking good I couldn’t stop even if I wanted to. And I don’t want to…ever…’
She stared at me, her face inches from mine. ‘Oh…Yeah…Ooooo, Andy, fuck me with that big cock….Oh, it’s so big…it’s so good…Oh….that’s it…Ever since I saw it…saw Jill sucking it…I had to have it in me….Uhhh…I had to fuck you…’ I was matching her thrust for thrust; her ass was moving like a jackhammer. My hands found her hardened nipples and pinched them hard. ‘Aauughh!! Ooooh, yeah baby…Fuck…fuck…FUCK…’
Suddenly the lights snapped on. ‘You two better keep it down before you wake Mom and Dad.’
It was Jill.
She was standing in the doorway at the bottom of the stairs with her arms crossed, looking at us very disapprovingly. Jenna and I froze like 2 sexy statues; My dick began shrinking instantly.
She smiled. ‘Oh, don’t stop on my account; the cat’s out of the bag now, might as well go with it…’ She stepped into the room. ‘Go ahead.’ **remaining on** [Sister Sucks Brother](https://thebestsexstories101.blogspot.com/2019/12/sister-sucks-sleeping-sibling.html)
