Fua grew up helping at her family's neighborhood bathhouse and is completely at ease around longtime customers. Years later, she has become a beautiful woman with long legs and soft, pretty breasts, while her daily routine remains unchanged. The difference is that the older regulars now get hard just from seeing her. When one delighted patron claims it is his first erection in 18 years, kindhearted Fua offers to help and eagerly sucks his neglected cock, asking him to keep it secret. He does not, and word soon brings a crowd of horny old men to the counter, turning the once-quiet bathhouse into a booming group-sex venue.
