Ruri, a married woman who fled her abusive husband and now lives hand to mouth, becomes desperate for money and offers her body to an older man obsessed with huge breasts. He subjects her to bizarre “tit harassment”: tickling restraints, aphrodisiac oil, nipple torture, and wildly bouncing titfucks during sex. Though hesitant at first, Ruri drowns in unfamiliar pleasure as her reason crumbles. This homemade record follows a married woman consumed by forbidden desire and gradually placed under the control of a man whose financial “support” masks his lust and relentless big-tit training.
