Des:“Hey, you have the courage to masturbate in your skirt and cum all over my pants! ? ”, the plain girl in the class who made an outrageous provocation. I cant back out here! Thinking so, I slipped my dick under her skirt and jerked her off... Hidden masturbation while keeping a cool face so that others wont find out is so thrilling that you cant help but ejaculate! Then, this time, the girl got really horny... In the end, I inserted it thoroughly! Maybe this is the real aim? Was I fucked?
