About Rika's Lustful Duty

Rika's Lustful Duty is an adult visual novel by Netoraku, built in Ren'Py and presented with animated 2D CG art. You play as Naoki, a married man who starts having vivid fantasies about his wife Rika with another man. At first he is unsettled by the arousal these thoughts cause, but he eventually accepts them as part of his desire. When his friend Kenta struggles with dating, Naoki imagines a forbidden solution: asking Rika to help him. The game focuses on romance, netorare, and mobile adult storytelling.

The current build is v0.10, dated February 28, 2026, and development is ongoing. It runs on Windows, Linux, Mac, and Android, with English text and uncensored content. The latest changelog entry adds 9000 words and three CGs with variations, while warning that old saves will not work. Earlier versions also show added story text, CGs, and animations, including a private moment between Naoki and Rika in v0.08.

Developer's description

Protagonist Naoki finds himself developing a fetish he doesn’t fully understand. At times, vivid images of his wife with another man appear in his mind—images that, to his surprise, excite him. For a while, he struggles to accept the thrill he feels from such an outrageous thought. But eventually, he surrenders to his imaginations. As he comes to accept this as a fantasy, he realizes his friend Kenta is having frustrations because of his lack of success in dating. Seeing his friend's struggles, an idea that is forbidden but undeniably thrilling, pops up in his head: "What if my wife, Rika, were to help him?"

Classic concept but the execution of the plot is very good, at least until the latest update. Hopefully the plot will develop slowly, logically, about the gradual downfall and corruption of the heroine character. Really need something like this to…
