Yarichin Kateikyoushi Netori Houkoku

What starts as a straightforward tutoring job pulls Kurisu — a university student — into something far more complicated through his work with Shizuku, a young woman from a wealthy household. Her father, struggling with erectile dysfunction for two years, approaches Kurisu with a bizarre and uncomfortable request: sleep with his wife, Akari, on his behalf, and record everything so he can try to work through his problem. Kurisu agrees, under specific conditions. Then he starts breaking those conditions almost immediately. What makes this 2-episode OVA from T-Rex stand out beyond the obvious isn't just the production quality — it's the dynamic that builds inside the Hatsufuji household once Kurisu starts operating with less and less restraint. The setup leans into psychological manipulation and desire, with a tone that sits closer to tense and provocative than lighthearted. It's adapted from a visual novel, so there's actual narrative scaffolding here rather than pure scene-to-scene content. If you've watched something like Kanojo x Kanojo x Kanojo and wanted something with a slightly darker edge, or if Oni Chichi's domestic tension appealed to you, this covers similar ground with a more deliberate focus on character psychology. The framing device — the recordings, the conditions, the husband watching from a distance — gives it a structure that most titles in this space don't bother with. Two episodes, clear setup, T-Rex animation. Worth a watch if the premise sounds interesting to you.
