Yuri-san (pseudonym) is an office lady working in the sales department of an insurance company. Known for her mature style featuring black pantyhose, she embodies both adult allure and a cute, schoolgirl-like charm—a true fantasy woman. She takes on a piston challenge using a fixed dildo, competing for a huge cash prize of 1 million yen. Each time the thick dildo thrusts deep into her pussy, her juices gush out wetly, and gradually she begins passionately begging, "Fuck me… I want a real cock…" Her pussy, warmed up and highly sensitive from the dildo, immediately squirts and orgasms intensely, drenching everything the moment a real cock enters. Her shockingly slutty performance—unimaginable for someone with her OL status—makes this an absolutely must-see release.
