Yes

Kimmy: Okay, why not I guess. Come to my apartment tomorrow after class, I'll tutor you.

The following day after class you head to her apartment. You ring at the door and after a few seconds, Kimmy, barefoot in a micro short and a shirt, opens the door.

Kimmy: "Oh John, come on in, I was waiting for you. Let’s sit on this couch."

You: "Are you sure that a couch in the living room is the best place to study math ?"

Kimmy : "Don’t worry, it’s the best place for the kind of tutoring we are going to have.

I talked with Ms Ren about what she expected from this tutoring and during this discussion we had an idea about how to make this tutoring the most efficient possible." she tells you as you both sit down on the couch.

She lays on it and puts both the feet on your lap as she takes off her shirt.

"Ms Ren decided to give me your key to make sure that you obey your tutor. The tutoring will be far more efficient that way." Kimmy tells you as you realize that she wears a necklace with a key, your key ! "As you can see I am now the one deciding if your cock will ever be liberated or not. Don’t forget that your chastity cage has been registered to the administration and breaking it would lead to you being ejected from college. So from now on, your tutoring will consist of obeying my every demand. Let’s start by kissing my left foot." she tells you as she rises her left foot to your face while starting to rub your caged cock through your pant with her other foot.

"Remember that if you disobey any of my orders I'll break the key to your chastity cage.

Also, don’t bother about maths anymore, Ms Ren accepted to make you pass her class no matter your grades as long as I was your tutor, so prepare yourself to spend all math classes below my desk worshipping my feet and legs, and maybe my cock also." she adds while starting to jerk off after having unbottoned her pants while you start kissing her foot.

Kimmy : "I'll turn you into the perfect foot worshipper."
