In this short scene, Akari tells her lover that she's been waiting for him to come back to her, but he hasn't. She tells him that she has been holding back because she doesn't want anyone to get in her way, and that she wants to be alone. He tells her that he's jealous of her, too, and she tells him to "wobble" , which is to squeeze him, so that he can feel the hot inside of her. Akari says she wants more of this, and he says he'll make her feel better. He says he can't get enough of it, and then he says, "spike" . He's not joking, and we're sure that's what you're thinking. We're guessing that this is a reference to the fact that Akari is pregnant.
