Thankfully, she returned. She was wearing that same pj set from the other night. She turned out the light and walked to the couch. Just to play it extra safe, she called my name a few more times. I ignored her. As she knelt by the couch, I opened one eye just that tiny bit (I had gotten very good at this in the last 2 weeks…) to see Jenna’s small round tits inches from my face. Her nips were hard and poking at her soft pj top. She reached over and unbuttoned my shorts; then she unzipped my fly. Soon my shorts and boxers were being slowly pulled down to my knees. She must have been terrified that I’d wake up! There. My cock and hairy balls were fully exposed to my younger sister. She knelt there for a full minute watching it as it pulsed with the beat of my heart. Her breathing became more urgent as she reached over and grasped it in her delicate hand. She didn’t jerk me off; rather she stroked it with her fingertips like she might pet a cat. She ran her fingers along the veins of my dick and across my balls. As she watched my cock grow, stimulated by her feather-light touch, I was overcome with the desire to feel her mouth on me. Was she going to suck it, as Jill had? The suspense was killing me.
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!!
