What a way to lose you girlfriend! This should be netorare and at least cheating. Honestly, treating your gf like your mom and her meeting a man that at least knows how to clean up after himself.
I want a sequel, probably just her and the guy meeting in the hot springs while her bf is somewhere being a prick.

Normally I dislike ntr, but I will give this a pass. The current boyfriend absolutely deserves to be cucked with his behavior and that sink at the end. How the hell does someone do that only over a 2 day span?!
