Sissy student pleases her professor

Professor Christian is finishing up some paperwork at home in his office while talking to some colleagues on the phone. Meanwhile he has feminized a student and turned him into a sexy and submissive babe who does whatever he tells her. She is sucking his cock on her knees like a good girl and then begs him to fuck her ass while she shows off her chastity cage. What a quick learner this sissy student is!
