I was in the car today ready to give an exam to FDS student Dean, and I was fucking horny. Dean got into the car, but he was surprised to see me. Turns out Dean accidentally booked an exam instead of a lesson with Ryan. He did not appear ready to pass, nor was he confident he could, but we still gave it a go. Dean told me he had failed an exam with Katy, so I wasn't expecting much. Thankfully, that meant I wasn't disappointed by Dean's complete lack of proficiency. I took him back to the exam center, and looking Dean up and down, noticed he was stressed. You can't learn when you're under duress, so I calmed Dean's nerves by pulling out my big fake tits and giving him a blowjob. This farm boy would fuck, and my pussy gushed at the sight of his cock. After he fucked me doggystyle and played with my ass, he came all over my mound. His jizz was delicious! Thanks Dean!
