"Welcome... Oh, it's you..." A quiet store filled with the scent of old books. Sitting at the counter, Fumika Sagisawa, now in her 30s, had transformed from a fleeting girl into a voluptuous married woman. Her husband, the former Producer, was extremely busy, and their night life was nonexistent. Appearing before her, who was unable to handle her accumulating heat, was a young student-like regular customer.
At first, they just talked about books. However, one day, the moment her fingers were entwined behind a bookshelf in a blind spot, Fumika's reason crumbled. "Not here... my voice... nhh." The thrill that a customer might come. The man's hand slipping under her skirt. Fumika leans against the bookshelf, stifling her voice, and reaches climax. Since then, the bookstore in the afternoon turned into an immoral mating ground.
The escalating acts extend to her home while her husband is away. "Try wearing... your old costume." Unable to resist the man's request, Fumika takes out her idol stage costume from the back of the closet. However, her massive breasts, matured as a wife and unable to defy gravity, do not fit into the fabric of her girlhood. "It's tight... it's improper..." Flesh overflowing from the bursting tight costume. Excited by that figure, the man, without contraception, pours hot seed into her womb repeatedly.
And several months later. Eating breakfast in the living room, the husband lovingly strokes Fumika's swollen belly. "I'll work hard, since I'm going to be a dad." Fumika sends her husband off with a smile. Minutes later, the doorbell rings. "Have a good day, darling." She unlocks the door and welcomes the "real father" of the child in her belly with a lewd smile.
