Before, we had always pulled curtainsbetween the showers for privacy. I just stood there and stared at her gracefully curvedbreasts, her firm buttocks... and the triangle of goldenbrown hair between her legs. As she lathered her body,I felt myself becoming aroused, my pussy starting toget warmer, and my nipples starting to tingle. Cheryl finally looked over at me and smiled. I smiledback and began to lather myself also with my bar ofsoap, while not taking my eyes off of Cheryl. After afew. And then she felt it. The heavily lubed dildo touched her anus, and Mesila gave a mighty thrust from her powerful thighs. A good three inches traveled up Gemmalyn's arse, and she bellowed with pain and frustration. "Noooo! Help! Stop!" Unnnhh!" Mesila grunted, thrusting again, and another two inches moved in. The crowd were really into it, and a large number had sprung from their seats. The jostled around the fighters, trying to get a better look, yelling obscenities, pure beasts of the. I began to sweat heavily. My shirt clung to my damp body; drips fell from my forehead onto my sister's face as I looked down on her. I pumped my cock in and out continuously, watching her breasts bounce back and forth under that rippling black satin slip. Kelly screamed with each inward stroke of my cock. Her face contorted as if in pain."Don't cum inside me!... Don't cum inside me!... Please don't cum inside me!" she begged, over and over.I ignored my sister's pleas. I had no intention of. "So, how has the incestuous sex been so far? You like it, Tim?" Marry asked."You know that stuff that just hit you two, I think that means I like it," I replied.We both laughed for a minute and kissed each other on the lips again. By then, we kissed as if we had kissed each other a million times before that, it was cool but still a little weird though."Tell me you love me, Tim, not like a sister," Marry said.I didn't know what to say to that honestly, I was in love with Emily, not her, why did.
