Nishino Riho

Ryota's mother and the heroine of this work. With a gentle and nurturing personality, she serves as a good wife and mother, caring for her only son Ryota while protecting the home in her husband's absence. She is also close friends with Ryota's childhood friend and best friend, Terashima Nagi, and has often looked after Nagi when she comes over to play with Ryota.

She is exceptionally beautiful and possesses a remarkably youthful appearance, often mistaken for Ryota's older sister by people meeting her for the first time. Her figure is stunning, and her I-cup bust not only emphasizes her strong maternal instincts but also captivates the men around her.

Despite this, she has recently begun to notice her breasts sagging and excess fat accumulating around her stomach, something she herself is quite self-conscious about.

She met her husband, Sumio, at work, became pregnant while dating him, and they married. They were initially a devoted couple, but after Ryota was born, Sumio began throwing himself into his work for the family's sake.

Ignoring Riho's pleas not to overwork himself, Sumio became engrossed in his job. While he steadily advanced in his career, his return times grew later, and he was often absent from home.

A dependable woman with a strong core, Riho never complained to her husband. She silently took care of Ryota, but deep down, she wanted a second child. This desire had recently started creating a rift between them. Partly because her husband didn't pay her much attention, she doted excessively on her only son, Ryota, and their mother-son bond was exceptionally close.

She also got along well with Ryota's best friend, Nagi, and the three of them often went shopping together. Though she would never tell her sons, she rarely has sex with her workaholic husband, Sumio. Her mature body feels neglected, leaving her increasingly frustrated.
