In the classroom or library, a devilish girl says something outrageous like "Masturbate under my skirt." I know it's dangerous, but I can't refuse, so I masturbate without anyone noticing! I even squirted a huge load on the devilish girl's panties! Then, the girl gets excited by the large amount of sperm that was ejaculated, and she lets me do something even more extreme than masturbation! It started as a mischievous forced masturbation, but in the end I was able to penetrate her! It felt good to jerk off.
