Yes, Jack's ass

"Do what you want Jennie" you reply

You see Jennie put the camera down and approach from behind. She lines up her strap on and slowly pushes against Jack's ass.

"Woah hey woah, what's going on?" Jack says

"Oh come on, you've fucked our holes, let us fuck yours" you say

"Yeah!" says Jennie

"Fine!" Jack replies as he goes back to thrusting into your tight ass.

Jennie keeps pressing the strap on into Jack's ass until the entire thing is inside him.

"Fuck" he sighs

Jennie then gets to work. She starts off slow and builds up speed and strength of her thrusts. You feel it as though Jennie is fucking your ass through Jack

"Fuck him hard" you say to Jennie

You can feel the thrusts hammering into Jack's ass and feel his cock expand in his ass, ready to come.

"I'm gonna cum!" Jack moans
