All the guests were sitting just to the left of the patio door so as to not block it.I followed Maggie in towards the bar. As we reached it she stoppe... and looked at me. She had a look of lust on her face that I had only ever seen on a porno movie before. 'Listen Dan' she said quickly, 'I want you to fuck me behind this bar. I'll bend over and start making the drinks. You pull my skirt up, and fuck me hard but be really quick – we don't want to get caught. Just pretend that you are making some. Mum smiled broadly. "Tell him." she said.They said, "You know we won it, don't you?" I didn't know what they meant. So to my utter horror, they explained that the competition had been to get my Mum as a sex slave for the night! Everyone there had signed sponsor forms for her to do it! Mum had been the judge, the criteria for tonight being that the two blokes with the biggest dicks would win!She'd taken all the males aside one by one, even the 18 year old lads and the dirty old men, and fucking. Oh my god..." Her voice pitched up into a squeak.Kevin peeled his mouth away from her pussy just long enough to beg. "I'm close too...please don't stop..."Anne nodded and sucked her big brother's cock back into her mouth, rolling her tongue and moaning around the head while her fist pumped his exposed shaft the way she saw the porn stars do it online when they were trying to get their costars to cum, she felt his cock pulse in happy appreciation.She could feel her pussy contracting, her skin. I maneuvered up over him as I kissed him, then began kissing his neck and licking around his throat. ‘You can feel my breasts, I’d love that,’ I whispered as he slowly slid his hand under my tube top. I went ahead and pulled it down, uncovering my boobs as I raised up, putting them in his face and rubbing them around. ‘You are so beautiful, Sara, oh, this is wonderful,’ he said softly as I took a nipple between my fingers and led it to his mouth. He opened and took it in to begin sucking. I ran.
