It's time for the sexy massage, and the narrator is all, "Oh, wait ! twitch, tweak, tweak no !" . He's going to do the same with his lower body, too, and he's sure that his nipples are going to feel "so good" that he'll be able to "smile" and "grinp" at the same time. The narrator is so excited that he doesn't even want to go to the bathroom. He just wants to get a "sexy massage" .
