SPRD-1519 — Tabiji: A Mother And C**'s Journey By Ryoko Iori

Ryoko works at a rundown hot spring inn. In the past, she left her son behind. One day, a university student traveling alone arrives at the inn. He is surprised to see Ryoko. He is the son she left behind. Ryoko is also surprised and approaches him, saying how much he's grown, but he yells at her not to act like his mother, so she leaves the room. Late at night, while Ryoko is bathing in the hot spring, he comes in. They are both surprised, but he becomes excited by the sight of her naked body and attacks her. Ryoko slaps him and leaves the bathroom. Later, he sneaks out to Ryoko's room, says he's been lonely, and sucks on her breasts...
