22-year-old college student Maina Yuuri (pseudonym) has a quiet, innocent charm. After reading online reviews, she casually decided to try an oil massage experience. Changing into the outfit handed to her by a female staff member on her way to the treatment room, her unexpectedly voluptuous figure—large breasts and round, full buttocks—became immediately apparent. As she waited inside the treatment room, she curiously observed the oils and aromas, appearing genuinely interested and giving off a sincere, serious demeanor. Then, when a male therapist entered, she nervously asked, "U-um… there aren't any female therapists today?" only to be bluntly told, "Today, it's men only," visibly shocking her. Clearly embarrassed at being seen naked by a man, she desperately tried to cover herself with a towel, but he immediately snapped, "I can't treat you like that," and yanked the towel away, leaving her defeated once more. As she continued to resist quietly, he firmly instructed, "Don't tense up—relax!" She flinched at his tone but obediently complied, gradually revealing a submissive, masochistic side. Sensing her vulnerability instantly, the lustful therapist switched aggressively into domination mode, quickly moving to finger her and suck her nipples. "Ah… ah…" she trembled softly, moaning in small gasps. Her melting body soon became completely obedient, surrendering to her unleashed desires. In the finale, he forcefully thrust his custom treatment cock deep into her bare, shaved pussy, delivering the ultimate creampie pleasure.
