It starts deep inside and the release is a force of nature. Beth and Sandy just stared at each other. I grabbed her wide hips and held on for the ride... Cindy, being Cindy, attacked with more force. "GODDAMN, FUCK FUCK, TIM fuck me HARD. FUCK MY ASS." So I went to town. Banging myself into her hard ass. Plunging my cock in over and over, fucking my sister's tight ass. I squirted what I had left into her. Then pulled out and sat back. Nikki rocked forward, "Thanks, Tim", then turned around, took. She swallowed and looked around helplessly before slowly walked the floor again, looking for a cubicle. On the one hand, Jason was right: everyone was studying intently. On the other hand, the place was pretty full. Most of the cubicles were backing to the stacks, which meant anyone could see her at any time. She finally picked one and sat down, surprising herself that she was wet already. She opened Jason's laptop to find a note to her, complete with a script. She started the webcam recording. Wow I thought she looks hot. She sat down on chair and began stroking my cock, it soon grew hard about 6 inches. Bill shouted suck him, no sooner than he spoke and my cock was in her mouth, omg it felt good. I was pushing her head into my cock when I felt Bill groping my ass, instead of complaining I turned my head round and kissed him ( never kissed a guy before or touched a guy ), I kissed him passionately, wow in meantime she was licking my balls, I was in heaven. Sue let go and opened her. It was late summer, September, I remember, and there was a tepid weather, I'm very happy to take a trip with my sister for to can stay near to her :-P because it was from a bit of time that she makes at me very excited to the maximum, not that I didn't knew before of having the sister hottie :-P, but in that last period i, without embarrassment, i had started to have good thoughts about my sister :-P, also caused by her of course :-P, which had led me to peek her during that last months and in.
