Even though Tsubaki wants her, he can't keep her from having sex with him. He's showing her that he's concerned about her, and she's freaking out. She's so excited that she can barely hold her tongue. She says that the kiss is so good that it makes her want to do the same thing with him, too. She tells him that sex makes both of them feel good, and that's the reason she wants to do it with him in the first place. He tells her that it's his fault, but that he wants to have sex with her because it makes him want her, too, which is why sex is such a good thing. He gives her a hug, and tells her to sleep well that night.
