There is a reason why Hashimoto, who is so-called rear-filled, is getting along with Ryota, who is introverted. That's because he wanted Ryota's mother, Mai, to be impregnated. Her voluptuous body can be seen even through her clothes...and her chasteness, contrary to her flashy appearance, made her feel even darker. One day, Hashimoto hears Mai calling her husband. Apparently, Mai is lonely because she can't see her husband who is busy with her work. When Mai hangs up on her phone, she doesn't notice Hashimoto's presence and begins to comfort her body...
