Hiyori, a cheerful and charming track and field athlete, is a hardworking individual who, due to her innocent nature, diligently follows her perverted coach's lewd training regimen without question. Standing at 160cm with a 92cm voluptuous backside, she engages in sex while wearing track bloomers, culminating in internal ejaculation. The scenes include intense oral stimulation, deepthroating, ecstatic orgasms, copious facial ejaculations, slapping and choking to climax, bloomer kissing, inverted oral stimulation, semen facials, double peace sign orgasms, and vigorous uterine penetration. She experiences abundant secretions of tears, cum, vaginal fluids, and throat fluids. This film depicts a series of ecstatic expressions from the masochistic yet pure athlete during her encounters with the perverted large-penised coach. The narrative unfolds through track and field practice and counseling, groping in track wear leading to throat training, oral stimulation and deep throat ejaculation, electric massager stimulation in an oiled swimsuit, ecstatic oral stimulation with massive facial ejaculation, bondage and orgasm in track wear, large-penis oral stimulation and internal ejaculation, and a bath scene with urination.
