Mami works as a receptionist at a bank, appearing to be a serious and professional employee. However, surprisingly, she has H-cup extra large breasts, her figure exuding an irresistible erotic charm. She's long been aware of her deeply lustful nature, and her behavior instinctively comes across as incredibly sexy. Her most sensitive spot is her nipples. While being penetrated, she pleasures herself by fondling and pinching her nipples, repeatedly reaching orgasms both from vaginal stimulation and nipple stimulation. The sight of her climaxing through both methods is even more depraved and intensely erotic than one could imagine.
