Former elite swimmer Rion Sono returns for her second release, still radiating almost impossibly pure innocence. After her work as a swimming coach, she meets a lineup of lust-starved middle-aged men armed with decades of sexual experience. They lead her through her first teased orgasm, her first raw POV sex, and her first threesome. Full-body licking, toys, blowjobs, facials, and oil-slick stimulation from multiple men turn her entire body into an erogenous zone. Thoroughly trained by their persistent techniques, the innocent athlete reaches her first orgasm—and then convulses through many more until her legs give out.
