it's from a game and some what soft core but it will get you off promise

I've already played this game.
Also, as a side note, there is no "yaoi", since everyone turns into a girl or futanari.
All the men and boys become corrupted, grow boobs and a pussy, and ask "Where's my dick?!" before learning to "summon" or "materialize" their penis.
Though, I do not remember the "kids" having balls when I played.
Though, I never saw the "after story" scenes either.
