"Sorry, your ass just looked so inviting"

I reply.

Millie just looks at me, then says:

"Whatever Matt."

"But you must have been done this way before, right?"

I reply.

Millie looks at me for a while, then says:

"Look, if I have been with a man all night and he has fucked me loads and made me cum repeatedly and wants to finish by sticking his dick in my ass, I am totally cool with that."

Millie pauses for a bit, then continues:

"But, I am not cool with a guy just shoving his cock in my ass unannounced like you did now."

She pauses for a second, then says:

"Get the hell out of my house."

Not good, I think to myself. Then gather up my things and leave.
