Grandpa will go crazy," I stammered even as I saw the beauty and humor of Abby's plan."They'll never know," my sister said, "unless, of course, the yo...ng scion of McLeod Manor can't keep his big mouth shut. The next Master McLeod," she added laughing."I won't be that for a long time," I said softly into my sister's ear even while knowing it might happen any day."Master Robert McLeod of Cock Lomond," my sister teased as she reached between her legs and squeezed my penis."We're Americans you. As she knelt there, she pulled my cock out of her mouth, looked up at me and almost groaned, rather than said, ‘Fuck, I really want you to piss in my mouth’. I was immediately intensely aroused, and I could feel that suddenly, I was just going to have to come, there and then, and I did just that, all over her face, rubbing my spunk into her mouth again with my cock. She then stood and kissed me deeply, making me taste my own cum, something nne else had ever done before and it just made me even. With a loud moan she had her orgasm.I quickly got up and locked the bedroom from outside. Now I took the condom that was hidden under kitchen shelf and quickly ran back to Monalisa. Now she got over me sucking my nipples as it was her turn to drive me crazy. Her hand crawled inside my shorts which was without underwear and started stroking it the harder way.Slowly she moved down and started licking my cock and then the balls. The blowjob that she gave was one of the best that I ever received.. For me, I had a massive hard on and my cock was rock hard again, I need to fuck this wonderful sexy aunty right now. My mind was working overtime, my cock had taken over and was telling me to start fucking her. I managed to slip of my shorts and was naked and ready to start. I slowly unhooked auntie’s bra which fastened at the front and then carefully rolled her panties down her legs and tossed them to one side. After all I need to get her legs wide open so that my hard rod of a cock could.
