"So let me get this straight. You'll tease me for an hour three times at whatever intensity I specify. As long as I don't twitch more than nine times, you'll let me fuck you all evening. If I twitch more than nine times, everything stops, and we fuck in twenty-four hours."
"Thirty-six hours actually. But you've got amazing self-control. You'll be able to hold on and then the rest of the day I'm all yours!"
She grinned triumphantly as she doubled to win the game. She scooted up the bed and began demonstrating her tease technique. I moved her hand away.
"Just let me think this through for a moment. No distractions! Even just snuggling up to you makes my cock twitch. I might as well ask you to have at me at full throttle and get my nine twitches over right away."
"Oh, but that way the game would be over, and you'd have to wait until tomorrow night to make love. Look, I promise to obey your every command while I'm playing with you. You can tell me to slow down, loosen my grip, just rub the bottom of your shaft, or suck only the very tip of that lovely cock. Whatever you want. The only thing is, you can't tell me to stop until the hour is up. I know you can do it. You can shut your eyes so you won't be distracted by my naked body. You can think about mowing the grass or taking out the garbage. I'm sure you'll have absolutely no problem controlling our cock!"
"I know your devious mind only too well. I could take your challenge. You'd make it easy for me at first, but in the last hour I bet you'd find some way to beat me. You'd talk dirty, encourage me to touch you up, give me those special soft kisses that drive me crazy; then I'd have blue balls and a huge lust-on for 24 hours and you'd probably flirt all day tomorrow to keep me on the boil."
"What me?" She looked incredulous. "You know I'd never take advantage of a man when he's down... I mean up! Besides, you might win, and you could be fucking me every-which-way after supper."
"I can't even beat you in a fair game of backgammon. The odds are really stacked against me in your twitch game."
I pretended to consider my options for a few moments while our traitorous cock signalled it's enthusiasm for the game.
I replaced her hand and grinned. "Your roll I think."
