>>54363193NTA, but why? It's funny how /dg/ just added their own lore to Satokoha, having Dawn intentionally teaching the easily impressionable Koharu that buttsex and oral were the only types of sex as a joke, then turning Koharu into Ash's personal turbo buttslut because of it, and then adding voyeurism from Dawn as they do it, to now giving Koharu a cock so things with Ash can get more interesting. Sounds like they've done more with Koharu's character than the show did.
