"Yes"

I reply, feeling my dick starting to get hard again already.

Millie's hand has moved down between my legs, and she starts to massage my balls slowly, rubbing herself against my thigh, purring in my ear, whispering:

"That's good Matt, because I want you to fuck me in the ass."

I feel my dick get hard as a rock hearing this, and Millie has by now moved her hand down to encircle my cock and is slowly jerking it up and down, then she whispers in my ear:

"Have you fucked anyone in the ass before, Matt?"
