"Let's check if you did it the way I taught you?" I finally got a girlfriend, but I'm too anxious to take the first step to have sex with her. Her best friend couldn't bear to see that, so she gave me some sex lessons → Thanks to that, I was able to have sex with her! "Did you do it right? Let me check it for you?" Her best friend, who cares about her friends, takes it in her hand and checks the results!
