In the classroom or library, there's a little devil girl who says crazy things like 'Masturbate in my skirt...'. Even though I think it's dangerous, I can't refuse. So, I masturbate without getting caught by those around me! And then, I end up ejaculating a large amount onto the little devil girl's panties! As a result, the girl who got excited from the large amount of semen that was shot out lets me do something even more intense than masturbation! It started with forced masturbation like a prank, but in the end, I was able to insert it! Masturbating felt good.
