Five years into her marriage, a slender, big-ass wife has grown bored with the same routine. When her husband refuses to let her work out alone with a male personal trainer, she convinces him to let her use a public pool frequented mostly by older patrons. That night, she puts on the racing swimsuit she wore in her school days and gets so turned on by the tight fabric digging into her body that she masturbates. The next day, she heads to the pool in an even smaller swimsuit and swims under lustful stares, where a persistent middle-aged neighbor draws this woman who has trouble saying no into humiliating swimsuit sex.
