Under the guise of a training session with no real name involved, this video peeks behind the curtain of an otherwise seemingly legitimate massage parlor. It captures the top-ranked worker, Miss Hoshikawa, closely collaborating with the manager, while newcomer Miss Fujisaki gets swept up by the two of them, gradually drawn into increasingly explicit situations. The footage is freely distributed as a means for them to earn extra cash. First, Hoshikawa teaches Fujisaki the basic procedures, slowly guiding her into the actual massage techniques. Fujisaki is then placed face to face with the manager as a customer, coaxed into changing into paper panties, and visibly shocked as a cock flutters into view right before her eyes. Convinced to strip down to her underwear because "oil will stain your clothes," the inexperienced Fujisaki hesitantly removes her treatment garments, unaware of what really goes on in men's esthetics. Her voluptuous breasts spill out from her bra, but senior worker Hoshikawa is no less impressive, her narrow waist and large breasts standing out just as much. Fujisaki is made to perform breast presses, obediently pressing her body close as instructed—her curvaceous figure on full display. However, she still resists taking off her bra. Naturally, even when told, "You won't see anything if we blindfold you with a towel," the camera clearly captures her huge bare breasts. Though she senses that "something feels off," she’s carried along by the momentum, gradually pulled deeper into escalating acts. In the end, witness clearly how the senior girl greedily rides the cock while the impressionable new girl succumbs, getting fucked bareback and creampie-pounded. Below is a partial list of the training content (also shown in sample images): breast stamping, bare-breast body contact massage, making her wear paper panties while flashing the cock, spooning-style service, nipple licking and sucking massage, forced facial cowgirl, bareback reverse threesome.
