Just in case you haven't figured it out yet, this is how it's supposed to go down: the narrator asks his friend, Mitsuki, to have sex with him. Mitsuki says she'll do it, but first, the narrator has to ask her to "squish" some of Mitsuki's "real boobs" . Um, okay, but Mitsuki doesn't want to do that, so she's going to have to do it with her pants on. The narrator can't believe that Mitsuki is going to do this to her "real" boobs, but he's not going to stop until she does it.
