Porn actor Shinrin Genjin and Kanna Misaki demonstrate how position, speed, angle, rhythm, and consistent thrusting can help a partner reach vaginal orgasm. The program explains why copying irregular, overly deep, or brutally fast thrusting from porn may cause pain and fake reactions instead of pleasure. Lessons cover basic movement, four advanced thrusting styles, tips for missionary, doggy, and cowgirl, positions that reach deep without a huge cock, a secret trigger that makes vaginal orgasm easier, and bonus foreplay. The techniques are then tested in unscripted sex: first by the veteran instructor, then by a novice performer whose awkward thrusting dramatically improves. A toy-masturbation bonus with Kanna completes the course.
