About SpaSiBo
SpaSiBo is a 3D adult game by CitizenCane, built with an engine listed as Others. It centers on a male protagonist and presents a focused spanking experience within BDSM themes. The overview describes it as a fairly faithful simulator rather than a broad adventure, offering direct sessions supported by volumetric softbody physics and detailed skin reactions. It also mentions some additional activities that use spanking as their main canvas. The title keeps its scope narrow.
The current build is v1.2, released on February 20, 2026, and the latest changelog indicates ongoing development. It runs on Windows and is available in English, Japanese, and Chinese, with no censorship. The update adds a second model, a paddle, a third pose suspended on chains, and a whip.
Developer's description
This is purely a spanking simulator game. No more and no less. If you just need a straight-to-business hardcore spanking session, it's there for you. And by "no less" I mean that it is a fairly faithful simulator. It has real volumetric softbody physics and detailed skin effects with bruising and blood. In fact, the "no more" part is what's not entirely true, as it does have some games that use spanking as a canvas.
