Can’t go a second round after cumming once, even though you want more all night? This instructional porn production claims to teach men how to shorten the refractory period and achieve multiple ejaculations, helping their partners orgasm internally through repeated rounds. Veteran porn actor Shinrin Genjin, credited with more than 10,000 partners, demonstrates his stamina techniques with Otsu Alice. The program includes street interviews, an introduction, a technique lecture, sex between Shinrin Genjin and Otsu Alice, handjobs, blowjobs, titfucking, and a final sex demonstration pairing Otsu Alice with a male amateur. The sex is presented without staged dramatization.
