"Date rape" lmao!! Definitely not with even her mother there knowing what's going on! Not to say he wasn't...scummy?
Well, one major thing he did wrong, it's the breach of trust, by, well, trusting into her(unintentional pun!) when they had a deal to let her take the action! Even if his hormones are rampaging, just take it slowly! Only in a hentai after that kind of painful defloration would a girl still be into it!
