Mai, a gentle and alluring woman, came to this salon today for breast enhancement. She changes into thin underwear, and the massage begins. The unscrupulous masseur, claiming it will enhance her breasts, slathers on oil and relentlessly stimulates her nipples. He even brings out a vibrator to further stimulate Mai's nipples. Next, he moves to her lower body, and Mai obediently spreads her legs. With her vagina and nipples being stroked simultaneously, she seems unable to bear it. Even when made to stick out her buttocks and perform oral sex, Mai perseveres for the sake of breast enhancement. For the final touch, the unscrupulous masseur inserts his penis without a condom. Forgetting all about breast enhancement, Mai screams with pleasure. The masseur continues to make love in various positions, bringing her to orgasm until the very end.
