Trans Ass Worship and Face Sitting

I found out that you, my Math Professor (Married BTW), were in a Fetish Personals Ads website (BIG Mistake), and I have been tricking you for months, making you give me As in my exams and homework but also making you do a lot of stuff to amuse me. This time I'm going a little bit more extreme. Today I'm bringing my Ts Girlfriend Poison, a tall model looking transgirl with a beautiful ass, I don't care if you don't like it because you are married and "straight". Would be nice if your wife was watching you licking a big ass.
