Mistress Land's tutor, Yuri Sato, teaches a reluctant student the art of ejaculation management in a chastity belt. Yuri, clad in a form-fitting latex dress, explains the rules to the nervous student, who's already hard in his shorts. She secures the belt around his waist, leaving his throbbing cock trapped and desperate. Yuri then proceeds to tease and taunt him, her CFNM lesson pushing the student's limits as he struggles to control his impending orgasm. Will he pass the test, or fail spectacularly?
