Maki Ohtsu, 38 years old. Concerned about her increasingly sedentary husband, she visits the public pool twice a week to maintain her health. Her body boasts a dynamite figure with natural 100cm I-cup breasts that strain and threaten to burst out of her swimsuit, drawing intense attention. Every time she swims, male swimmers around her can't help but fixate their gaze solely on her. "At first I was embarrassed," she laughs, "but now I flaunt it on purpose"—and admits this attention sends thrilling shivers through her body. Lately, her sexual frustration has grown so intense that she can't feel satisfied unless she masturbates in the shower. Witness her alluring figure as she seeks to finally release these pent-up desires that sweat alone cannot wash away. Enjoy the sight of her massive natural I-cup breasts swaying and her athletic, water-sports-toned body moving with pleasure.
