Downloading Medical Exam from my Best Friend

I thought it was going to be a simple physical exam. But there's nothing simple about what happened next.

Over dinner, my best friend Liam asks me for a favor. His roommate dropped out of med school, and he needs someone to practice the physical exam on. Of course I can help him out.

We go back to Liam's dorm and start the exam, and suddenly, I'm feeling breathless, my skin is tingling, and I'm incredibly turned on. Liam has never touched me like this before. We're just friends, and it's just a practice exam for med school.

Why do I like it so much?

As the tension builds between us and I feel his breath in my ear, I can't stop myself. A stethoscope and fingertips aren't enough. I need more from Liam, desperately, and this exam is about to get much deeper.
