small studio apartment...we're going at it full steam in missionary, then we hear a key opening the front door. No knock, no bell, just open and enter. She jumps up, knocks me out of the bed, grabs her robe and starts running for the door. Too late, the dude is already in, I hear them talking. I get off the floor and start to get dressed in record time, cell phone falls on the floor making a loud bang, then there's silence in the other room. I'm dressed in a panic, obvious full erection, condom still on no time to worry about that.
She comes in and tells me it's the maintenance guy there to fix the garbage disposal. Probably clogged from all the used condoms? I leave and this dude is staring at me. I walk to the car, dick going soft, condom slides off and is now swimming in my shorts. Get in the car reach in and fish the slimy condom out and drop it in the door bin forgetting i put it there. Two days later at the carwash, they find it and I see one guy holding it up, showing another dude and laughing....
I was traumatized and gave up the hobby for two days.
