Even though she doesn't have any major complaints about her relationship with her husband, daily life as a housewife tends to build up unexpected stress. Kumi is no exception—small frustrations have piled up over time, leaving her emotionally strained and on the verge of breaking. Seeking a way to relieve her stress, she decides to respond to an ad from <HitoPara>. Since this is her first time cheating, the plan starts slowly with dinner, gradually easing her mind and body into the experience. Initially nervous, Kumi quickly transforms into an insatiable woman once she's touched by another man. As she fully realizes how incredible his cock feels, she eventually begs desperately, "Fill me up completely!"—achieving deep, satisfying fulfillment by the end.
