Face Fuck Her Into Submission.

If this keeps up it'll be dumb luck that decides the victor. If you're going out, you're at least gonna enjoy the ride.

You start pressing your hips against her face, forcing your cock deeper into her throat. Heather gasps and coughs but recovers quickly.

"Come on, bitch. Let me at least enjoy it!" you call out to her between licks of her still twitching cock and pussy. "Your mouth was made to suck dick. You want more of my cream? Cuz I'll give it to you."

You feel Heather moan along your shaft and it feels superb. You, on the other hand, mearly tease Heather's cock and cunt. You keep switching between them, building the tension in one before abandoning it for the other. This is a favorite method of yours to heighten your own orgasm when pleasuring yourself. That gives you an idea. Maybe you can win this with one big orgasm instead of several small ones?

Heather is still clearly trying to get you to cum as quickly as possible. You let her and keep toying with her, your hot breath enough to make her twitch and gasps.

"That's it!" you pant. "I'm close! I'm gonna cum in your whore mouth...!"

You bite your lip and do just that. Heather lets out a deep moan from her throat. You can tell she's very eager to get off herself.
