This is a submission by contributor Kurotori Eiji (pseudonym). [Below from Kurotori] Her name is Airi, and she normally appears pure, cute, and like a sweet young lady everyone adores. Working as a nursery school teacher at the daycare run by her parents, she gives off a gentle and calm impression. She also has a partner approved by both their families. However, behind this facade lies a deeply masochistic pervert. Once her switch is flipped, she transforms instantly into a lust-crazed woman who climaxes repeatedly, captivating anyone who watches. Wearing an erotic pantyhose, her reactions during fisting are extremely exciting. The footage of her first successful fisting is a rare scene where her genuine innocence merges with perverted responses. There are also scenes where she is whipped, leading to surprising developments. She even says things like "Hit me harder," fully exposing her extreme masochistic nature. The unique charm lies in her strange allure and the intense, passionate reactions that contrast sharply with her appearance—this is the highlight of the session.
