I've been married for 23 years... Mitsuo and Suzuka, a couple who are still good friends. Even when his son Yuji grows up, he still takes a bath with him every day. And in the bath, Mitsuo, who has a strong libido, sucked on Suzuhana's nipples while deredere, and her mother became just a female in the bath and forgot to suppress her voice, and sucked on Mitsuo's. - Her parents are chiming each other in a small bathroom, and she doesn't know that they are mating, and Yuji gives them a "bath comfort goods" as a gift on their wedding anniversary. * The contents of the recording may differ depending on the distribution method.
