Allow him to continue
From Create Your Own Story
You think of stopping him, but what's done is done, right? You decide to let him work to completion inside your ass. He has only inserted his cock head, but you feel like your asshole is being stretched open. He is jerking off very rapidly. His masturbation is causing his dick to wiggle inside your ass, sometimes popping out of you, at which point you eagerly wait for him to press it back into you. He is soon breathing heavily, and you can tell he is about to cum.
This is when he breaks his promise. Just when he is on the verge of cumming, he slams his hips forward and fully violates your ass. His hips smash into your assflesh as his dick spears you fully. You cant stifle a lust yelp as he starts to fire jet after jet into your asshole.
When he is finished, he pulls out of you, followed by a strand of cum.
"You lying asshole," you shout back at him as you drop your skirt and readjust your top.
"Calm down. You earned your payment. Besides, you enjoyed it"
You...
