41-year-old tall, slender Misato. She married her first partner and has lived faithfully with him ever since. However, their intimate life has dwindled to just once a month, and as her child has grown and free time increased, the desire for infidelity has slowly begun to stir within her. Telling herself it's just this once, she takes action—only to find herself captivated by her own lewd, beautiful nipples, making escape impossible. When they're pinched and twisted, shame and pleasure intertwine, causing her body to writhe in ecstasy as she reaches climax. This fleeting transgression becomes an unforgettable, special memory she'll carry for the rest of her life.
