Hicky

We where at a spring party at school then I had to use the restroom so I was in the woman’s restroom and I was just finishing washing my hands then out of nowhere some guy walked in the restroom and I told him this was a woman’s restroom then after I said that he looked over at me pines me to the wall then started to suck my neck!! I was yelling at him to stop but he didn’t stop. I also tried to call for help but I guess people didn’t care. Then he stoped and ran away I knew who he was but seance he was in a higher grade than me I never could find him I was too afraid to tell my friends and parents so I don’t know what to do now I have a small hickey on my neck covering it up all the time please tell me what to do!!!
