K. I have done more than see my brother's penis. I have jerked him off." Jill's eyes popped wide open in surprise. "I've even sucked him off a bunch o... times."Jill was red in the face but had to ask. "Did he do it in your mouth? You know, spurt his stuff?"Mary nodded in the affirmative. "Ya, and I liked it. I even swallowed all that goo."Jill asked a lot of questions wanting Mary to tell her every detail of the sibling encounters. Finally she asked. "Mary, do you think Roger would let me watch. Certainly they were not the sort of boys who only had an interest in big-busted girls! More probably, they were attracted by the indefinable sexiness I was giving off, now that sex was constantly on my mind!At the same time, I was just as fascinated by my female classmates, and especially by the size of their busts. Since Tanya had started developing so dramatically, I had become quite an expert in big tits. All of the girls in my class had tits except me. Most were average sized, but a few. The same English butler met us at the door and welcomed us. Well actually he welcomed Percy and Dr. Jim, waiting for the rest of the Percy's family to be introduced to him so he could welcome them. By the time he was done Angela appeared with hugs and kisses for everyone.Percy thought that his kiss lasted just a little bit longer that all the others.Angela smiled at me and whispered, "There aren't enough bedrooms. Is it ok if Tara and Jim share?"He nodded "yes".Then she floored him, "And us. Her big ass swallowed this fist no problem.” I lied. “You’re full of shit. Connie never did this shit.” I guess she wasn’t that stupid. “Why do you think she was walking so funny? I thought this is what you wanted.” I pushed again. She cried out. “I guess your ass is too small and tight… and young.” That did it. “Alright, fuck my ass. Put it in… all the way.” I needed no more encouragement. I pushed hard. She pushed back. “AAARRRRGGHH!!!! YEAH!! HARDER!!” I pushed again and felt her ass.
