At a motel one night and right at the height of a great night of sex with my wife and the moment before ejaculation the fire alarm went off. We threw on towels and ran out to see a few others in just towels. I'm standing there with my orgasm basically running down my leg. Fortunately... No fire though.
When I was having sex with my roommate's "friend with benefits" and my roommate walked in on us. They weren't that serious. It was awkward. I was getting it doggie style, looked up, and there she was, just staring at us. To the guy's credit, he didn't stop.
My spouse and I needed to get away from the kids. We got a sitter and went to dinner. Having not been able to have sex for a while we were pretty worked up. So after dinner we headed to a local park with a lake. Migrating to the beach in the dark we laid out a blanket. On thing lead to another and we were in the throws of passion totally naked when suddenly we heard a loud voice over a PA system. We both froze and waited. With no one in sight we picked up our rhythm. The voice returns from across the lake freezing us in position again. We didn't know what to do. What I did do was go limp. We scrambled to redress when the voice rang out again. This time the wind must have blown in the right direction and we heard what was said word for word. "Cab 16, pull into dock 19. Cab 22, dock 3 is ready." With that we just fell back, relieved, but the mood was broken. The PA rang out again announcing another dock availability so we packed it in and headed back to our vehicle. We found a fuck and go, checked in as the Smiths and 20 minutes later we went home.
When I was a teen, my girlfriend and I thought the house was empty. We went to her room...buck naked and going at it full on when the door opens and it was her mother's boyfriend. He closed the door real fast, we got dressed and went downstairs and he asked to talk to me alone. He told me he wasn't going to tell and was only interested in making sure we were using protection. But that instant when it happened was pretty terrifying.
A large metal ruler slipped off a shelf right onto my face and cut right through my lower lip. But was on the edge of orgasm so even though he lost it he was kind enough to finish me with his tongue. LoL!!
In high school I was at my GFs house, we where suppose to be putting her little sister to bed. We got her sister to bed and she fell asleep almost instantly. My GF unzips my pants and starts giving me head. All of a sudden we hear her dad opening the bed room door! She stands up and faces the dresser. I turned to the dresser also zipping up as I turned. Well I caught my little buddy in the zipper. OMG did it hurt! Her dad sticks his head in the door.." Every thing OK?" My GF said "Yes", and dad closes the door. That was probably the longest 30 seconds of my life!
