About Sin of Lust
Sin of Lust is a Unity demo by Mr. Cucumber, played as a male protagonist living with Rena and Erika. It is a 2D animated point-and-click dating sim with sandbox-style freedom, built around two women whose desires and hidden secrets draw the narrator into a risky web. The player sees private moments at work and at home, uncovers buried secrets, and watches his feelings and self-control weaken as temptation grows.
The current build is the October 19, 2026 demo, released for Windows in English and uncensored. Its changelog lists an initial release for the demo, so this version is the first demo release. The game presents mature themes plainly, while the story asks whether all involved fall together into desire in this demo.
Developer's description
Sin of Lust, Living under the same roof with the seductive, married Rena and the sweet, charming Erika seems like something anyone would envy, yet it pulls me into a dangerous web woven from their desires and hidden secrets. Whether by accident or temptation, I keep catching glimpses of their private moments at work and at home. Secrets long buried begin to surface, layer by layer. As I dig deeper, my feelings toward them twist into something far more complicated... and far more dangerous. And my own desire is slipping out of control. In the end, will all of us fall together into the abyss of desire?
