Follow her into the bedroom

You don't even bother to dry off yourself as you follow Anna into the bedroom. She crawls up onto the bed and pauses for a moment, giving you a perfect view of her still dripping pussy and asshole. Looking back, she wiggles her ass for you, and the strand of cum that had been slowly streaming out of her lips finally falls and lands on her calf.

"Are you coming?" she asks, as she turns over and lies down on the bed.

Without a word you dash over and climb onto the bed yourself. In one quick motion you swing a leg over her body and straddle her chest. Each of your legs pins down an arm of hers at the elbow and she smiles up at you.

"Are you going to fuck my face, sir? I am utterly helpless to stop you."

You don't reply, but your hard cock is answer enough as you bring it up to her mouth. Anna hungrily accepts the tip and opens her mouth wide for you. Your movements are slow at first, as you begin to inch deeper and deeper into her mouth, but you begin to build up a bit of momentum. In the shower she teased you almost to the point of cumming, so you don't think you'll last very long; you think you'd better make the most of it.

Reaching down, you grab the back of her head and pull up as you thrust forward. This drives your cock even deeper into her mouth, and Anna gags ever so slightly before moaning. You build up speed as you begin to ferociously fuck the face of your ex. It's clear that she doesn't have much if any gag reflex, which is something you never had the chance to find out while you were dating. But now you're pushing her to the limits of what her mouth can handle as you thrust your cock down to the hilt inside of her. Slowly her face starts to turn slightly bluish as she struggles to breath, but she doesn't try to stop you. She can't. You have her totally pinned and your hands are controlling what her head does.

But it doesn't matter, as after a few more thrusts you feel your balls swelling again. You only have a moment to decide where to cum.
