ROE-119 Days of incest with my mother at my parents' house where the whole family left the nest. Momoko Isshiki

Yuji was born as the second son of three brothers. His mother, Momoko, had the impression that he was a quiet child who didn't assert himself, but... One spring, the older brother got a job and lived alone, while the younger brother entered a boarding school to go on to baseball. His father moved away from home and his life changed in a hurry, and Yuji and Momoko began living with their mother and child. Momoko feels a sense of loss as the bustling house suddenly becomes quiet. Seeing his mother like that, Yuji feels frustration and emptiness, and tries to regain his mother's love, which he couldn't monopolize until now.
