SleepMaster1 Game Collection is a adult sandbox game developed by SleepMaster1, built with the Ren'Py engine. The latest update landed in July 2026. The game runs on Windows, Linux, Mac and is available in English.
Overview
You play as an ordinary guy living a seemingly normal life with your girlfriend and close circle of friends. But things slowly begin to change. What starts as harmless jokes and subtle provocations soon turns into something much darker.
Your friends begin pushing boundaries, testing loyalty, and trying to take what is yours. At first it’s just teasing… but the situation gradually spirals into manipulation, temptation, and betrayal. How far will things go before everything you thought was yours starts slipping away?
As the story progresses, you’ll be pulled deeper into a world of NTR, power dynamics, and twisted relationships. Lines blur, loyalties break, and desires you never expected may start to surface.
The game explores themes of jealousy, corruption, humiliation, and sexual discovery, where nothing is truly safe — not even your relationship, your friendships, or the people closest to you.
And as things spiral further out of control, you might find that you're not only losing control of those around you… but also discovering new sides of yourself you never imagined.
