The ultimate ass work that focuses entirely on asses! On a hot spring getaway with her husband, Kuroki's ass is so attractive that he can't help but stare at it. Unable to resist, he takes advantage of an opportunity when her husband is away and attacks her ass! Kuroki, who was sexless, loses all sense of reason in the wild play, accepting all of the man's perverted ass-loving play and climaxing over and over again... The emphasized big ass will transform you into a masochist! Please worship this firm, top-class ass!
