Driving back to Millie's house

We sit in silence for a while in Millie's car. What just happened in the lingerie store has been a really erotic experience for me, so I am still trying to digest it.

Millie sits quietly too, I can tell she is doing a lot of thinking.

We continue to sit in silence, then Millie is the first to speak:

"Matt, are you planning to fuck me in the ass tonight?"

Millie's very direct question surprises me, and I decide to deflect it:

"Millie, one does not plan such things."

Millie replies:

"Ok, let me rephrase, do you want to fuck me in the ass?"

"Millie, you got a gorgeous ass, so naturally I hope to fuck you in the ass, at some point."

Millie replies:

"Ok, good, so you don't expect to, you know, fuck me in the ass tonight, just because we bought that outfit, right?"

"Naturally not." I reply, then continue: "But I am curious about what you think about the butt plug?"

"Same here" Millie replies "I have never experienced a butt plug before, so let us try it when we get back to mine."
