Lately, my tutor Sierra (TeenyGinger) has been teaching me about anatomy! We discussed male anatomy yesterday, but today we're going to focus on female anatomy. I thought I would already know everything, but then I realize there are a lot more differences between breasts than I expected! Sierra decides to take her shirt and bra off to help me visualize some of the differences. But... Then we both get aroused!! While talking about the feeling, Sierra asks me if I've ever touched myself before, and I haven't! I didn't really know how to. Luckily, she brought along an extra vibrator, and demonstrates how to use it for me. She walks me through all of the different sensations I will feel, and eventually we both have an orgasm!
