A practical sex guide for anyone who wants to develop a woman's internal pleasure zones and help her achieve vaginal orgasms. Veteran porn actor Shinrin Genjin teaches OTSU ALICE how to use three powerful toys, with demonstrations, a male masturbator trial, massive squirting and repeated male orgasms during sex. The production says the lessons are performed for real without acting or staged reactions. Correction: the product mistakenly labeled “iroha SVR +” in the video is actually the “TENGA SVR PLUS.”
