No

You try to think about baseball, but you don't really know anything about baseball. Count some sheep? That's for falling asleep. Fuck!

If you can't slow yourself down, maybe you can speed her up. It finally occurs to you that you could push back as Mary fucks you, and maybe do the sorts of thing that women do in porn. Like dirty talk!

"Oh God, Mistress. Please fuck me harder!" you say, trying to sound more sincere than the average porn star. You search the deepest recesses of your mind for every dirty, naughty thing you've ever heard in porn and wished that Kay would say to you while you were fucking her. "Holy fuck: you're so big!" "Cum inside me!" "I'm going to cum!" and the like.

Interestingly, announcing that you're going to cum is distracting enough to prevent you from cumming, and it has the desired effect on Mary. "Yes, take it you tiny-cocked sissy!" Mary screams as she reaches her climax and shudders against you until she comes back down. You don't know whether it's from the reaming or the vibrating, but your sphincter seems to be too numb to feel pain any more. This has been a surprisingly positive experience. Even being submissive to a woman hasn't diminished any aspect of it. In fact, it was hot as hell.
