I am game" That's the sport, I knew you would be." and we fucked again very hard that night.The next Friday, Syd called me. "It's time big guy, here i... the deal. While she is a virgin she has had plenty of dildos and shit in her pussy, so you don't have to worry about hurting her. Oh, and check this out, she is on the pill to keep her periods regular, so you are good to go. Just come in and go up to my room, I will be in the living room."I went over and entered the house. I looked over into the. She wanted to sit on my lap and have her back rubbed. I knew I was busted and that she would probably think I was a total pervert but I had no choice but to twist back and sit up letting her soft rear press into my bulging jeans. My penis reacted to the feel of her ass by further stiffening within my jeans. She paused for a second, but settled in on my lap as though nothing was awry. Breathing a sigh of relief, I gave her a long slow back rub which she reacted to by moving around ever so. Sandy glazed eyes followed my hand as it fed each singular button down my front, through each stitched hole, and as I opened it up, my small breasts came alive as each nipple started to ache for attention, standing proud from the center of each breast, I could see Sandy's nipples do the same, both her hands holding him in-situ, his non-stop pre-cum running down her bare thigh, as she knelt with him between her legs, his tongue nuzzling her shaven pubis, 'I'll go first, you help him in', she. Her pussy knew what was up without conscious instruction at all.Getting inside my angelically snoozing sister was trickier than licking her. I could be gentle and soothing with my soft, wet tongue, but my cock was hard and needed to go much deeper.It was a struggle of self-control to push into Lexi so very slowly. No kissing, no fondling, no putting any unnecessary weight on her. Just sliding into her waiting pussy, barely breathing, and filling her up without waking her.I had to fuck her so.
