I [F] 22 used to fuck myself on the fire escape of my uni halls

At uni we had a fire escape. I lived with six other people on the sixth floor and the stairs went from the bottom to the ninth floor. Outside, partially exposed through a grate-like outer covering. The people above us used their fire escape too. One night, I’d been fucking myself so much in the regular way that i needed more. So at 2am, i picked up my rabbit vibrator, put on a robe and went outside. There was a police station opposite and a busy main road with shops below so it was extremely risky for my 20 year old self but it was so hot. I sat on the steps, knowing so many different people could catch me, and opened my legs. I was so wet already, i pushed my vibrator inside my soaking pussy and fucked myself on full speed until i came. Opening my robe to feel the breeze on my nipples made it extra hot. Reminding me i was out in the open, exposed for anyone to find ?
