When I Streamed a Classic Game, My Favorite Heroine Just Goes Out of Control

I tried to do a commentary playthrough with arbitrary restrictions on a famous game, but for some reason I found a hidden scenario and my favorite heroine just went on a yuri rampage. By the way, since this was written on a whim while drunk, it might continue or it might not. Oh, the games that appear in this work are originals with names I made up arbitrarily, but if by any chance there's a similar title, I apologize. It has absolutely no relation to that.
