[M/f] skipped school today and hooked up with my boss

A little back story: 18/f about to be done with school. I have a fwb and my best friend that her and I occasionally mess around but nothing committed. Her and I work together and have been best friends since 4th grade. We have a notebook that has sex acts we want to do, with a ton of different variations, if its been done yet, and how it was and who it was with. Sex with a man 5-10 years older was on the list.

So last night him and I are closing up (I work at a smoothie place). We are in the back room counting money, he says flat out how attractive I am and how he wishes he was younger. I tell him I want to be with an older man (he's 26). This leads to sex talk and I tell him some sex acts I've done, I know its getting him horny. We leave work after and walk to my car. He comes in to kiss me and I kiss back. It escalates yo him having his hands down my pants, squeezing my ass. I tell him to stop because we are in the open and I got school in the morning. He does and tells me to text and maybe sext later. He unlocks his car and I decide to jump him. He was a little confused but excited. I tell him to put the seat back and undo his pants. I blew him in the parking lot. After I swallowed he said it was the best BJ he got in a long time (I've had lots of practice).
