Plain and quiet Nami-san is a married woman with a boyish demeanor. However, when her huge breasts became wet and see-through during a shower repair accident, and her hot gaze met mine, my reason crumbled in an instant. We began meeting in secret, as if to fill the void left by her husband's absence. With each encounter, the desires sleeping deep within her bloomed more vividly, and I drowned in an endless sea of guilt. Seeking her, even though she has a place to return to, we melt together deeply and intensely day after day. This secret passion, etched into the shadows of everyday life, can no longer be stopped by anyone.
