For a long time, I've been turned on by public exhibitionism, almost getting caught, or getting caught 'risk free' by strangers will bring me, in the best cases, to orgasm without even touching myself. Pure thrill.
Recently I was on a business trip, and when I arrived back at the motel in the wee hours after a meeting, I couldn't resist.
First, I slipped down to the pool. It was closed, but the dive had no security, so I got naked and slipped in. After a refreshing dip, I got frisky. I walked around the motel complex, tempting fate, but it was so late that no one was stirring. So, wrapping a towel around me, I walked through the front door and lobby. The lone clerk was busy watching TV in the office, so the towel dropped, and I walked through stark naked.
My room was at the back of the hotel, so I had to pass dozens of doors. The thought of someone stepping outside for ice or whatever kept me rock hard. After making it to my room unmolested, I had to up the ante....
Back to the pool (this time with my trunks and towel back in the room. Then, through the lobby again, in my birthday suit with a raging hard on.
After a few trips up and down the halls, with no 'safety net'-if someone saw me they'd get the full show, with no hope of escape-I was so horny I had pre-cum leaking onto the hallway carpet.
Finally, I ended up back in the lobby. Anyone coming in the front door, or from the other wing of the hotel, or from behind could see me. The girl at the front desk was in view, doing paperwork. I think she caught a glimpse of me, but I shot a load right onto the lobby floor-no hands, just pure excitement!
