FERA-151 Yurika Hiyama, a mother who thought it would be okay to have sex just once, but ended up in a swamp because her son kept making her cum.

I was pushed down by my son. - I can't compete with physical strength. - No matter how much I scold and soothe, my words don't reach my excited son. - Feeling in danger, Yurika had no choice but to accept the offer on the condition that it would only be done once. - If you pull him out and let him calm down, he'll realize that this is an unacceptable relationship. - That's what I thought. - However, the son who has learned the taste of Yurika's mature body becomes even more uncontrollable. - Yurika was also the one who fell into the forbidden pleasure.
