Ms. Yamaguchi, who says she has never been made to cum by anyone, including her husband, made a sincere request: "I really want to experience an orgasm." First, she learns how to cum from clit stimulation, followed by a thorough vaginal development using a vibrator for the first time. During a threesome, her body becomes completely lewd, experiencing internal orgasms from a cock while simultaneously cumming inside and out from clit play. A shy and reserved housewife loses herself in endless climaxes!
