I'm from the future, you see, and there's this really hot chick here.
But while I'm in the past, I don't age or anything. My hair doesn't grow, I'm lucky I can change my socks.
So I don't want to get entangled here, even for something like frequent sex. But. . . I'm not going to get laid anytime soon in my own world, because my parents are kind of. . . yeah.
