It's the first day of their new apartment, and the two of them are having sex for the first time. The narrator tries to get the other guy to move so that he can have sex with him, but he can't, because he's so terrified of what it will be like to be splayed out on the floor. The other guy tries to squelch the moaning, but the narrator doesn't want to hear it. He tells the guy to "plop" and "swallow" , which is to say, to "swallow" . The guy says he'll try it again, but it's too late. He's afraid that if he does, it'll be too painful for him to be having sex with her.
