This instructional porn feature explains how to give a woman deep vaginal orgasms without the painful jackhammer thrusting people often copy from porn. Yui Tenma says 72.9 percent of surveyed women have found aggressive pounding painful and that many fake orgasms to protect their partners' feelings. The course instead targets the sensitive area near the cervix for deeper, longer-lasting pleasure. Veteran porn performer Genjin Moribayashi leads eight unstaged lessons: a lecture with Yui; external deep-zone stimulation and fingering by a novice performer; positions that make deep orgasms easier; beginner-friendly deep sex; Moribayashi's external stimulation demonstration; blindfolds, bondage, fingering, and toys; deep stimulation combined with a blowjob; and advanced deep intercourse. The final lesson shows how sustained stimulation can keep an orgasm going and produce repeated climaxes.
