Did

If you ask me it wasnt rape. Because Arisu kept pushing Usa on and on clearly knowing what's coming next. Remember what Usa said in early chapter about Arisu "he likes to stir people up" or something like that. A lot of people say "no" or "wait" in the act of *ahm* so I don't think his "wait" was one of the real ones after all he did to Usa, knowing what's coming. And he keps trying to excite him so yeah...

I see. Thank you for your reply!
