I pushed my brother back down on to the pool table, “Lay down you fucking pervert!” At first my brother wouldn’t do what I said, so I yelled at...him again. “I said lay down Mark!” My brother laid down; he raised his head up to see what I was doing. I began to undo his shorts as quickly as I could, “Katie what…what are you doing?” “You got to see my tits, I want to see your cock.” I pulled my brother’s shorts off and boy did I get a surprise! I never knew my brother had such a big cock! I. Bobbie was having an effect on LD's cock. It was no longer soft. However, it was not yet fourteen inches. When the song had ended, Bobbie looked at LD's cock and observed, "It doesn't look hard yet." She pouted and added, "Am I dancing right?"Everyone chimed in, "Yes!!!!"Bobbie continued, "Then, why isn't LD hard?"LD reluctantly replied, "Your dancing is great Bobbie, but what I probably need is something a little more revealing."Bobbie looked at me as she asked, "You mean you want me to. I kissed her on her lips but she didn’t responded. I raised my head back and saw her on the verge of tears but those turned me on more don’t ever do that to me again. I am your sister and we should not do this.” saying this she moved away from me and I backed off and went straight to my room. I was horrified at my mistake. I should not have done that. She was my sister but the more I tried the more she captured my mind and finally I decided I had to fuck her in anyway and I came downstairs and. He looked about ready to kiss me. He began moving his lips toward mine.I felt his breath on my cheek, but then, he pulled his head away,turned toward the window, looked dismissively outside, and coldly said,"Thank you so much for agreeing to help tonight. I look forward toseeing you make someone else smile." His shoulders were tight, he wasshaking, apparently holding back tears.I left, feeling quite crestfallen. I really hope I didn't upset him.Why did I put the moves on him even after I knew.
