It went into the knuckles and so she pulled out and did it again, urging her fist in deeper until my cunt couldn't take it and her hand slipped in. 'G...ood! Now you take it bitch.' She closed her hand inside me and started fisting me, trying to force it out of my cunt and then she jammed it back in, building in speed and tempo until I was being properly fist fucked. I rocked back, accepting my position as a slut, wanting her to completely own me. I arched my back trying to get more and more. She. I told her that she should stick to looking sexy and I'd handle the wagering. She asked if I would like to make a private bet on the win. I said yes I'll bet you and we each get to pick what the looser has to do. I told her if she lost the guys get to run a train on her. She said you can't be serious, I fucked one of your friends once by the pool and you are still obsessed over me doing it again. I said first of all it was two guys by the pool and yes I want you to give your pussy away again.. I am a nymphomaniac to tell the truth. I said sure pull ashore by a some trees and we’ll see what develops. He says to me no lets just do it right there in the boat. I take a quick look around and see we were still by ourselves and proceeded to strip. I knelt down in front of him and slowly stroked his hard cock. When I felt he was ready I slowly took him into my mouth and swirled my tongue around his head as I sucked on him slowly sucking him deeper until I had as deep as I could and slowly. "I can't do it," I said."Rubbish," said Kay. "You can and you will. Watch me."I did watch her: I watched her arch her back slightly; I watched her lithe little body tauten; and I watched as a cascade of piss began to stream from between her lovely legs and splash onto the floor. I watched her face, too, relaxed and absorbed, as though what she was doing was entirely natural. Piss began to splash over her bare feet and ankles, then pool over the floor: she carried on pissing, seemingly.
