Having fun during class hidden under the teacher's table.

Today i have a physical exam and the truth is that i am fatal. although my physics teacher is not at all my type a mature married man makes a very rich package. i decide to try my luck under his table and play around with his cock for a while. hiding between her legs i start rubbing her hard tail and all this makes me so horny that i end up with his cock in my mouth while i can't stop sucking it.
