Asahi, a married woman, enjoyed a fulfilling and harmonious sex life with her husband, living each day in marital bliss. However, everything changed when her husband brought home a colleague—one who happened to be her former senior, someone she once admired. Unlike her condescending husband, this man was sincere and treated her with consistent respect, gradually stirring emotions within Asahi. Even while sucking her husband's cock, she found herself thinking of her senior. In private, she repeatedly masturbated, fantasizing about him. Eventually, the senior showed up at her house and confessed his feelings. Yielding to their mutual desire, the two engaged in a forbidden affair, indulging in adulterous sex and drowning in deep, illicit pleasure.
