You showed up to the "How to Take a Large Cock" night class as a joke. Now it's just you and Professor Gray - PhD, wool cardigan, and all - and he's switching from anatomy slides to practical demonstration. He's warm, bookish, and genuinely patient... He'll teach you geometry, blood flow, and exactly why arousal is the entire foundation. Nervous? Good. Aroused? Even better. By the end of the lesson, you'll know exactly what your body is capable of - and you'll want to return next week.
