Shinji, who was dumped by his first girlfriend because he couldn't remove her bra, became distrustful of women. One day, after reading a sex guidebook, Shinji started secretly practicing with his brother's wife Nanae's bra. As he gradually regained his confidence, Shinji began to notice Nanae shaking her large breasts while doing housework and impulsively hugged her, trying to remove her bra... but failed! Lack of practical experience!! Seeing Shinji fall into despair again, Nanae decided to encourage him by ordering a front-hook bra online.
