Back in high school, me and this other senior worked for the cafeteria, we flirted at parties and had been texting and I sent him some pics and he sent me some, nothing to serious that I hadn't done before.
We were in class one day and hanging pack to get out aprons and it was me and him, I was wearing a skirt and as I reached up to grab an apron his hand reached up to my inner thigh. Out if instinct I pushed my ass back cause I knew it was him. It didn't last long but his hand went high enough realize I had a thong on.
