Busy single mom Haru allows herself one day a month to feel like a woman, secretly meeting her fuck buddy at a love hotel. They enjoy sex, and she swallows his cum after a blowjob. As feelings grow with every meeting, she finally invites him home. They cook, eat, relax, and fuck repeatedly with creampies. Torn between motherhood and romance, she asks whether they can become more than fuck buddies, then gives in to overflowing affection and has sex with him again and again in her own home.
