You sit on it

For the first time, you pull your attention away from the fuck fest happening in front of you and move it towards Jack's exposed cock, waving free in the air. Before now, the thought of doing anything with it would be nowhere near your mind, but as the intense aching of your body continues, you think of how good his finger felt, how empty you now feel without it, and clearly how more must feel better. You watch as Jack gives it a few light strokes while looking directly at you. You so desperately wish you could do the same to yours, otherwise you probably wouldn't be doing what you do next.

You hesitantly and a bit awkwardly begin to scoot your body closer to him. He instantly moves back a bit giving you more access to his lap as you start to move over him. You can't help notice his smile as the side of your face is directly in front of his, you feel his hot breath on your cheek before you lift and twist your leg over his, facing your back to him. You pause for a bit, hovering over him as you feel his tip just barely pressing between your cheeks. You take a deep breath before lowering yourself onto him.

"That's it Tiger!" He says, his breath now on your neck.

There's a bit of pain at first as you feel yourself spread, though it seems nothing compared to that of your constrained penis. You slowly inch down, fearful that you'll fall too fast and impale yourself. You grip your hands onto his knees as your legs shake underneath you, unsure if it's from the effort to keep you up or from the anticipation of what's to come. You soon feel Jack's hand against the both sides of your waist, assisting you in your endeavor as you move lower and lower. You can't help but let out a small gasp as you feel yourself rest against his bare lap. He's completely inside of you. The feeling of fullness is strange and intense yet exactly what you needed. You stay there for a moment taking it all in before you feel his hands moving up, signaling you to do the same with your body. With even shakier legs, you do your best to lift feeling motion inside of you once again, giving you even more pleasure than before.

As you continue your slow yet steady motions, you look back at the three pups. Emily is still on her back, but the other two are pulling out of her. You see them qucikly move around her, switching sides, as you catch Emily briefly move her gaze towards you. A smile apears on her face as she witnesses you seated on a mans lap with your ass filled, but her view is cut short as a dripping wet cock is soon shoved back into her mouth. The two get back to it, though this time on oposite sides, as the sight causes you to lift up a little faster. You feel yourself clench a bit as if your body is worried he'll leave you again, before bringing yourself back down.

"Oooh yeah!" Jack moans from behind you. "I knew you'd like this."

Your body seems to be in full control now, as fears of going too fast or too hard no longer seem to matter as you pick up the pace. The sensation of your insides rapidly stretching and spreading around him sends pleasured waves throughout your body. You look at Emily's lust drunk face as she's taken again and again and wonder if you have a similar look. You've never experienced a feeling this intense before, your heart pounds and your breathing quickens as you're practically bouncing.

As your tiny cage continues to tremble, the only question is, will this be enough?
