That Summer, I NTR’d My Friend’s Girlfriend

Twenty days is all the setup needs. A roommate brings his girlfriend home to crash until the semester starts, and the shared apartment stops being peaceful almost immediately.

The premise stays close to that one apartment: three people, a countdown, and a protagonist who's supposed to just be sharing space. What starts as background tension between roommate, girlfriend, and player turns into something the game is clearly building toward from day one, and it doesn't pretend otherwise.

Play is point-and-click movement through a small sandbox, day by day, choosing where to be and who to be near as the arrangement erodes. The scenes that follow are censored, and the game tracks toward more than one ending depending on how far things go before those twenty days run out.
