About Waifu Sex Simulator

Waifu Sex Simulator is an adult parody simulator by Lewd Fraggy, built with the Others engine and using digitally rendered character models. You play as a male protagonist, choosing from more than 1,000 models based on well-known anime, games, and TV shows. The game includes more than 300 separate movement sets, covering many positions and intensity levels. You can interact with the models using controllers or Leap Motion hand tracking.

The current build is v4.0, released on December 23, 2023, and development is ongoing rather than finished. It runs on Windows in English and is uncensored. The v4.0 release follows earlier updates that added many new models, new motions, new scenes, fields, and fixes for controllers, Leap Motion, rendering, windowed resizing, and other general improvements.

Developer's description

Dive into the world of anime and hentai, choose your favorite character from a pool of more than 1,000 models coming from the most famous animes, games, and tv shows.

Atrocious UI, sheer learning curve, no updates. This was my first foray into VR hentai "games", though this piece of software is more of a watered-down experience than any actual interactive game. The best thing I can liken this to…
InfestedTerran92 2023-11-08 ★★★★★
Unuseble piece of code 0nly the developer himself and his 2.5 fans will understand where and how to enable animations. There is no convenient scrolling through a bunch of lines of “animations” and models. The interface is designed by programmers…
nightboy_ 2022-04-09 ★★★★★
Quantity over quality I can see the work done, but that's rather a framework than a game. There is a lot of content but now that he consider the core of the game done he is "selling" models for it…
