To save my mother from a crushing 50 million yen debt, I have no choice but to accept a vile contract: becoming a human nipple-toy for a wealthy tycoon. Every day is a living hell of relentless stimulation and sensory-boosting torture. My body, once innocent, is now rewired to explode in pleasure at the slightest touch, turning me into a desperate sex slave begging for more.










Her nipple orgasms are incredibly erotic. I'm so satisfied watching this actress get her chestnut-sensitive nipples teased to the limit. I love how they both knead them relentlessly, and watching her drown in pleasure until she finishes is just the best.
Marina Yakuno takes a job as a housekeeper for wealthy Fumitaka Yoshimura to pay off her mother's 50 million yen debt. The hourly wage makes it impossible to pay off in a lifetime, so Yoshimura offers an alternative: do whatever he says. He demands she strip naked, and she complies. Yoshimura then fixates on her clitoris and pussy, whispering lewd comments. Marina-san is not only blessed with H-cup breasts, but her naked body is stunning. When Yoshimura pinches and pulls her nipples, she immediately reacts and orgasms—naturally, as anyone would. The nipple torture continues with brushes and toys, eventually leading to her licking his nipples before he initiates sex. While she rides him, he continues to tease her nipples with his hands. Her high-pitched moans and constant orgasms are incredibly erotic. Watching her react so sensitively on screen is a turn-on. When Yoshimura switches to missionary, she presses her own nipples while climaxing—a sight that heightens the excitement. The scene where they lick each other's nipples is super erotic. While the full-nude sex is great, the highlight is definitely when she wears a cute light blue and pink bra while being teased with toys. Her handjob/breastjob is also a masterpiece. The film ends with Yoshimura finishing inside her. Overall, it's a compelling watch where Marina becomes a 'nipple slave' to the wealthy Yoshimura.
