Today Sophia is studying for a test about the male reproductive system and the book is not really giving her what she needs to pass the test. Luckily for Sophia, you are there to help her with her studies. After all, Sophia is a hands-on kind of a girl. Do you mind taking out your penis so that she can have a close look? It really would help her. You are a helpful guy, so you offer to show her your dick and how you can make it nice and hard. What happens if you stroke it harder? Is there something that she can do to help you get harder? Sophia thinks that if you see her titties it will help you get hard. She really needs to pass this test, so she will do whatever she has to do to understand how your penis works. You have always had a thing for girls who wear glasses, and Sophia is particularly cute in them. Your precum does not go unnoticed by Sophia and she is convinced that she can help you along if she lets you look at her pussy. It is at this point that she asks to hold your dick in her hand because she really needs to see you ejaculate. Are you nearly at the point of orgasm? Yes? Well, then, you should take your penis in your hands and make yourself cum. Do you want to cum on Sophia's breasts? That would definitely help her for her test tomorrow. Now she knows all there is to know about the male reproductive system, thanks to you
