Alan and I were in bed together under the covers, with me stroking his cock. He closed his eyes and started to groan and move his hips into me, and then grabbed my arm hard and his body tensed and he threw his head back and moaned.
But we looked under the covers, and... nothing. There was no semen and his cock wasn't getting soft. He'd felt an orgasm, but he hadn't ejaculated.
Sadly I can't tell you that I kept going for the gold, because he kind of freaked out and asked me to stop. But I wonder, if he'd let me, what might've happened. It's possible that was just a slightly dysfunctional orgasm, but it's also possible that he was on the verge of multiple orgasms.
And how goddamn cool would that be?
