And what would Alice think??

You snap out of your post-coital pink haze. "Charlotte," you say to her carefully, "did you just tell me that you love me?"

Charlotte looks up at you briefly, shooting you a worried look, and then looks back down. "Yes. I love you, John, like a good girl should love the men close to her."

"How does Alice feel about all this?"

Charlotte shrugs. "She's happy we get along so well, I would guess."

"She doesn't mind..." you start, feeling out the situation, realising that in this alternative world you have probably had sex with Charlotte before. "... that we fuck?"

Charlotte shrugs again. "Why would she? You know me almost as well as you know her, it stands to reason that you have sex with me almost as much as you would with her. I know you like her a little more, but if nothing else she might be off having sex with other friends, so sometimes you'll play around with me instead. It's only fair," she says.

You're confronted once again with the reality that your girlfriend Alice --- well, not your girlfriend in this world; and not anyone else's girlfriend, ever --- will freely fuck any man that she knows well enough. Quite possibly in public too, based on what you just did with Charlotte.

You're not sure how to process this, so you decide that you'd like to confront Alice. "Fair enough," you say to her. "Shall we go inside?" you tell her.

"You've already come inside," she says to you with a little smile. "But yeah, let's get inside. I love the feel of you inside me, but now that we've fucked, I feel a bit exposed."

Charlotte dismounts you, and you pick up your trousers and Charlotte's panties as she goes to the door. Charlotte unlocks the door and opens it, gesturing for you to enter. “Please John, after you."

You enter into the dorm, the girl closing the door behind you.
