ROE-253 Momoko Isshiki finds a micro bikini meant for her stepson and tries it on

Momoko is a married woman who married her husband in her later years, and she has a stepson, Takashi, who is a university student. Even after three years, they still use polite language and have not closed the distance between them, but one day she receives a package addressed to her. She becomes suspicious of frequent packages from the same company and peeks inside when Takashi is out, finding a sexy swimsuit. She thinks it is shameless but is tempted and puts it on.
