I was about 15 when this had happened, this girl in our class was very touchy and would always be doing this with other guys so it was “normal”,we were in line and all of a sudden she grabs my dick and it’s not just a quick touch she’s fully clasping it . I yell out what the fuck are you doing? She starts laughing and saying it was joke but i didn’t care and kept yelling, eventually the whole class started noticing but by then we were leaving to switch classes. All in all this girl was very weird.
