Now I’m riding him, thrusting back and forth my slim slender body on to my son’s fingers. I scream out and he lifts from my tit and kisses me hard... my tongue entwines with his as I shudder with an orgasm.He pulls his fingers out from me and grabs my arse with both hands and pushes me up against the wall. I can feel his cock growing by the second as I am lifted and slid up the wall and now I know what his intentions are. I hold on to his neck then lift my legs around his body, all the time. I feel the walls of your pussy begin to clench around my cock, slowly starting to milk it as you raise and lower yourself on me. I thrust back now as your rhythm stops as you feel an orgasm begin to shudder it’s way through you, you bite your tongue in an effort not to cry out, and I bend my head back to kiss you on the mouth, licking your pained tongue and ever so slightly a tiny scream of pleasure escapes you, muffled by our kiss. I carry on thrusting up into you and you look behind us. Dare you to show up, I thought.I drove home thinking about my ad. Could I really do it with some random person? I bet I could. Besides, what’s the difference between that and a plastic toy? A real cock is more exciting. And a lot less pathetic. Without the hang-up of a relationship to screw things up I bet it would be amazing. Yeah, yeah I could do it. Someday.I got home. Empty house. I stripped out of my clothes and got on a nightgown. I got nowhere to go anyway, might as well be ready. Although the men appeared blasé when the women rejoined them, in fact a new world record had been set and all four women had finished under the previous record. But they didn’t say a word about the time and it never occurred to any of the women to ask.Barbara, still lying with her head on Susan’s thigh, felt something strange on her belly. Opening her eyes she looked down but only saw Sue moving her finger on her skin. “What are you doing, Mistress?” she asked.“I’m playing tic-tac-toe, silly,”.
