Voluptuous milf and office lady Makimura Ayaka undergoes a dramatic transformation when her nipple sensitivity suddenly skyrockets, turning her into a squirting sensation. Troubled by pigmentation around her nipples and areolas, she searches online and obtains a high-end care cream. After applying it before work, her body begins to overheat, leaving her restless and flustered. A concerned junior colleague checks on her during a break in a private office room, only to find her temperature rising uncontrollably. Overcome with desire, she exposes her big tits, pulls his hand toward her breasts, and begs to be groped. Their intense encounter quickly escalates into a passionate affair.
