This instructional porn claims to solve premature ejaculation and help men make partners climax through penetration. Veteran performer Genjin Moribayashi teaches control techniques through street interviews, a before-and-after amateur sex test with Hono Wakamiya, Kegel exercises, handjobs, masturbation control, and a full demonstration scene. The production emphasizes natural sex rather than exaggerated fake orgasms or mindless hard pounding.
