I have a childhood friend who I love very much at school. But in my new class, there's a bully who bullies me! When my childhood friend tries to help me, he gives me an unreasonable exchange: "If you date me for a week, I won't bully you anymore!" In order to protect me, my childhood friend decides to date the bully for a week (and keep having sex with him)! I spied on the two of them having sex and was overcome with guilt, but I couldn't help but get an erection. But I didn't just watch...
