An instructional porn feature claiming that anyone can learn to make a woman squirt simply by copying its techniques, including squirting during penetration. Veteran porn actor Shinrin Genjin explains why rough finger-fucking copied from staged porn is often painful and demonstrates techniques intended to feel genuinely good. The program includes a lecture with TOTSUKI RUISA, practical squirting instruction with an amateur woman, squirting sex with Ruisa and both veteran and novice performers, and a final demonstration featuring massive repeated squirting during penetration. The lesson ends by presenting a repeatable method for bringing women to orgasm through squirting.
