He doesn't let you

The sounds, the smells, the sights, the sensations, are all so intense. You feel your constricted member fighting for it's life as your back door is working hard to get it release. Your wieght is now on the front of Jack's legs as you support yourself with your hands in order to get more momentum as you are now feverishly sliding up and down his pole.

"Oh God!" You hear Jack moan.

You think nothing of it at first, but you soon begin to feel him twotching inside of you.

Knowing what's about to hapen, your motions become frantic. You are so close to getting release but losing the hard cock inside of you will definitely stop that from happening.

"Please! Wait!!" You say, no longer thinking of the role you're playing but out of pure desperation.

You suddenly feel Jack's grip on your sides tighten as he begins to lift you up. You try your best to remain on, get a few more strokes in order to get you to completion but you unfortunately arent able to. Jack's cock is soon flinging out of you as you collapse onto your side. You watch in torrtured agony as Jack immediately grabs onto it and begins rapidly pumping. It's only seconds before a stream of white shoots out, splashing against your bare skin.

"Ahhh!" Jack sighs as he leans back. "Sorry, but im not allowed to reward human behavior."

You writher and stretch as the emptiness you feel echos through your entire body. You were so close!

"That may have been a more **** punishment than I intended though." He says as he looks at you with a sympathetic grin. "So I won't stop you from getting off elswhere."

He points over to the pile of pups. Coope and Bandit, still thrusting themselves into Emily, though it's clear they're getting tired as the two are using the top halves of eachother's bodies to support themselves.

"You'll want to hurry though." Jack says. "Looks like they're almost finished."
