She wants to explain a few things first

Brittany walks into the bedroom and motions for Adam to join her. Which he does, still throughly entranced by her body and his plans for it.

"So um, listen I just want to have a wee talk before we get to the real fun tonight" She says eying up Adam's crotch

"I used to be a guy and I kept getting these very slutty urges and I tried to put it off for a while and convince myself I was meant to be a man, the urges eventually got the better of me and I started talking part in online humiliation sessions and because of this the nanites eventually made me the girl you see here today, are you okay with that?. "

She says this extremely quickly as if in a rush to get all the words out. Adam then realizes she is in a rush as she reaches one of her hands under the waist of her skirt and begins to rub staring at Adam waiting for his reply. Damn this was a horny slut, he was going to have some serious fun with this one.

"Sure I am, in this world everyone moves up and down and I don't think I've ever seen someone in a more **** need of fucking than you, call it community service."

She blushes apparently taking this as a complement and then replies

"You said you'd never fucked anyone before, were you telling the truth?

"yeah I was why? Adam responds

"Great, that's good because in this world it's proportional how much you move up and down and it gets harder the more **** either side gets to move"

"so?" Adam responds more than a little confused

"so, after repressing my urges for so long I've decided, I want to go right to the very bottom and I need someone not so near the top to be able to do it quickly, someone like you. Oh and as an extra special treat for you I've never actually had sex with a guy, I'm virgin like you, although I have taken dildos in my ass and pussy before and I'm all yours to use hunny, however you like"
