"Actually, I think we did have sex"

I reply.

Millie gives me a confused look, and says:

"What do you mean?"

"Well, it was an accident, but my dick was in your pussy, so we did have sex." I reply.

Millie looks at me, shaking her head, and says:

"Why do you think we had sex?"

"Well, the act of fucking is a cock going into a pussy, there is no lower time limit for how long the cock has to be in the pussy for it to constitute fucking." I say.

"Firstly, watch your language, secondly, no, if penetration is unintentional then it does not constitute a sex act." Millie says.

"Wow, you sound almost like Bill Clinton." I reply.

Millie laughs briefly at the joke, then says:

"Matt, why are we arguing over the definition of what happened."

"Well, it is important to me if we fucked or not." I reply.

"And why is that?" Millie asks.

"Well, since if we fucked, then." I say, pausing mid-sentence.

"Then what?" Millie asks.

"Then it would be the first time I fucked someone." I reply and throw a stone into the water, watching its splash create ripples across the water.

Next to me, Millie buries her face in her hands.
