Make her suck your dick, you don't want to let this opportunity go to waste

"Anything?" you ask, moving towards her.

"Yes!" she replies.

You straddle her on the chair, your crotch just in front of her face as you unzip your fly. You pull out your cock, which is already erect in anticipation, and brush the head across Kristy's lips, her head recoiling back in surprise.

"Open up then," you order, grabbing the back of her head. As soon as you see Kristy's lips part you pull her head forward and thrust in with your hips, your cock driving deep into her mouth. "Oh yeah, that's the stuff!" you grunt slowly pumping your hips into Kristy's submissive mouth, fucking her face.

Using one hand to hold her head while you thrust your cock in and out of her mouth you reach down with the other and grope Kristy's ample tits. You squeeze the generous mounds and pinch her nipples through her shirt. You then grab her head with both hands and start to fuck her mouth faster and deeper as your orgasm gets close.

Kristy gags a little as your cock pushes right into the back of her mouth, at the entry to her throat, "Just relax," you tell her. With a loud grunt you ram your cock harder at the back of her mouth and push into her throat. Her nose pushing into your belly sets you off into climax.

Kristy chokes and gags around your shooting cock as you clutch her face tight to your twitching loins, you cock shooting heavily inside her.

"That's it!" you gasp as you draw back so that only the head of your cock is in her mouth, "Swallow the whole lot bitch." Kristy submissively sucks on the head of your dick as you milk the last of your sperm into her mouth. When you finally withdraw from between her lips there is an audible popping noise.

"Ok let me go," pleads Kristy as you push your cock back inside your pants and zip up, feeling rather satisfied.
