Despite the strict rule prohibiting sexual acts, this alluring men's spa allows customers to use the therapist's throat as a substitute for the vagina. Through erotic arousal massage, male clients become highly sensitive and erect, and even while gagging, they smile and beg for deeper thrusting. The spa girls give in to the temptation, losing consciousness from intense deep throating, awakening their extreme submissive instincts. Their throats, soaked in bodily fluids, spasm uncontrollably as they reach climax. Eventually, they surrender to the forbidden act, granting intercourse to eager clients, repeatedly climaxing and ultimately receiving creampie after creampie.
