Requesting any vanilla with Natsu Yutori from Blue Archive in a Halloween setting - i.e. sex in a lewd costume (you know the classics: erotic witch, slutty vampire, succubus, barely-covered-mummy, pumpkin-themed microbikini, that one Mashu Beast outfit from FGO, etc.)
If you need me to post a specific costume, will post something. I just wanted to give extra freedom for this
