I was up against the cupboards and had to crawl over her to get out. It was a tight fit with the both of us on such a small mattress. As I tried to cr...awl over her, she started to tickle me. I fell on top of her, my hard on hitting right against her belly. She kept tickling me and it was almost like humping her. It wasn't good for me, because I didn't want to shoot all over her or in my pants.She finally stopped and I went to the bathroom to pee. As I was in there, I figured I had to do it by. She returned and sat on the bed in front of mewith her legs apart. I heard the distinct hum of her vibrator."Now I want you to look at my panties, don't let me see your eyes northof my belly button, and don't even think to make a noise." She beganswirling her vibrator around her mons and stopping it on her clitoris.She repeated this action for three to five minutes, as I stood therefrozen."Ah, uh huh.......oh," she panged. My tiny dicklet was swollen inside itschastity, precum was flowing into. " Jessica said innocently. "Do you like it?" she asked her brother with the same innocent tone."I…er…" Chris stammered as he looked down at his sister's treasured jewel, not knowing how to answer that. Without all that hair he had a clear up-close view and was surprised and turned on to find it so seductive, her lips tight and cute, and her slit a glowing pink underneath her pale mound. For the first time in his life, the notion of having sex with his older sister crossed his mind and it shook. Now Sally had not only been single but had not had any cock for a very long time, Lucy shocked me one day by suggesting that I help Sally out by fucking her. Once I regained the ability to speak I agreed as long as she was there and participated, so it was agreed.Sally came around a couple of nights later and we sat around the table chatting, neither of the girls drank but I had a couple of beers. After a while Lucy suggested we get in the hot tub, we all stripped naked and got in the warm.
