Welcome to Sex Ed: Drop Your Pants and Give Your Teacher a Blowjob

I always try to be the best professor I can, but teaching sex education is difficult. Especially when my only student is not paying attention when I'm trying to teach him everything I know about penises because he is too busy jerking off right in front of me. Today I tried a different approach to help him understand and pass my class: I let him suck my cock and pounded his ass with it. Now that he has seen, felt, and tasted my penis, I'm sure he'll never forget a single thing about it. I have to admit, the way he rode my dick might have earned him some extra points.
