Yes

Dan can't say no in his present state, he has to cum, he is past the point of no return. Steph strokes her cock for a bit and lustfully look down at her current conquest, the first woman she's going to fuck. The fact that Dan used to be a guy only makes it hotter.

"Fuck me please" Dan pleads, with no shame left in him.
Steph adjust herself so that she is over him, her cock lightly rubbing over Dan's aching pussy. "I've noticed you don't have a hymen, but I'll be gentle just in case"
As Stephs cockhead pushes its way slowely in, Dan wraps his arms around her. "Oh god its so big"
"You are doing great" Steph kisses Dan deeply while sliding further in.
Dan feels light-headed, his new muscles accepting this cock into them. It's fully in now, and the sensation is unbelievable to Dan.

"I'm going to start moving agian"
