Trendy dark fitness. Amidst loud music and dim light, the body of Rururu, a student with large breasts, is relentlessly toyed with. During exercise, she fights her fear of being found out by those around her each time she moves vigorously, as her clit and pussy are fully developed to shameful climax. Pleasure ruthlessly piercing the sweaty skin, and secret internal ejaculation unbeknownst to those around. Not just for relieving sedentary lifestyle, but primal orgasm exercise born from the perfect sex spot of darkness. Shame itself turns into pleasure, the full picture of lewd fitness.
