FERA-140 Emiko Sugioka, a mother who thought it was okay to have sex just once, but ended up in a swamp after her son kept making her cum.

``It's only once...'' No matter how much I scolded him or told him gently, it didn't reach my excited son's ears. - There's no way you can compete with her strength. - Emiko thought about it and decided to accept her child's desire. - This is a one-time mistake. - Let's forget about it and get back to everyday life. - I told myself that and decided to endure it. - However, contrary to her feelings, her body reacts violently to her son's piston. - Emiko cums unconsciously and shows her son the true face of a lewd bitch.
