My brother asks his girlfriend if she'd like to have sex with him. She says yes, but she's worried about her future brother-in-law, so she doesn't want to go out with him, since he'll be her future husband. My brother says that he's already had sex with her, and that's why they can't have sex. He's not worried about his future brother in law, he says, because they have had sex before, and they'll have sex again. He asks her to kiss him, and she says no, and then she kisses him again, and he kisses her again. They're having sex again , and it's like they've been having sex for a long time.
