A JOI tease for my bound, fetishy professor. You can't do anything right now but eventually I'll let you loose. And I know you'll lose control, won't you? Try? Try to resist, professor?

I think my parents are getting suspicious of our arrangement, so I'll need you to give me an A- instead of an A+ this time, throw them off the scent. Of your fetish addiction.

This dizzying performance will go right through you, teach.
