All in

"MMM Now this is a nice ass, tightest one I've had in a while, try and relax while I loosen it up"

She stays resting her cock with the head just inside Adam's tight, once virgin hole. She moves her cock head in and out of the tight opening, preparing it for the main event.

"Sorry about this, this is really going to hurt, who am I kidding this is going to be amazing! Squeal if you want by the way, the vibrations'll feel really nice on my cock, currently buried in your faggot ass"

She then begins to slowly but forcibly bring her hips forward, plunging her cock ever deeper into Adam's poor, wrenched open, virgin orifice. Adam squirms and squeals but can do nothing more due to his bondage and slowly starts to accept it. It was going to happen no matter what he did now. It was out of his hands.

Eventually she bottomed out in Adam's ass and her balls hit the Adam's now soft, curvy rear.

"Not long left as a man now my dear"

As she says this she reaches round and grabs the pathetic remains that could certainly no longer be called a cock.

"Let's make you what you are"

She pulls all the way out of Adams ass and then in one smooth motion rams herself all the way back in side. Causing Adam to squeal in immense pain. But underneath that pain Adam realised that he was actually enjoying himself. Her massive cock was touching a place deep inside him. It made him insanely horny. He was truly her puppet its just she didn't use her hands to control him, she used her cock instead.
