Convention Bathroom

I was 19 years old bi 6'4 about 150lbs. I worked at g*ft shop on the first floor of the convention center. Had to wear a tie and dress shirt. I have been with 2 older men and a few young guys and enjoyed sucking there dicks as much as I could. Hadn't had any dick for a month and as horny as fuck. Alot of suits worked in the building not counting the different conventions that happened. This was on a Friday late afternoon. Not alot of people around. Mostly a few dozen guys from there 30s to 50s walking around the main area some in the shops others at the restaurant bar. I liked watching these guys in there suit pants, occasionally seeing there dicks jump in there pants, or watching them grab and adjust themselves. I got off work and needed to pee and for what ever reason I had a shy bladder, I couldn't pee around people. There is a bathroom on the 2nd floor down a long hall that want used much unless there was a huge convention. I go upstairs and walk to the bathroom it's not super bright, just lights over the vanity. It has 2 urinals and 2 stalls. I go in and go to the 2nd stall I unzip and start to pee and the door opens and my pee stops. I look over and a guy in his 30s is at the sink straightening his hair and his tie. I'm watching him In the mirror and he looks back and sees me looking at him. He walks to the urinal beside me and says hi and turns and I here his zipper. I zip up and go to the 2nd stall for some reason and raise the lid. I start peeing and I don't here the guy anymore, but I didn't hear the door open either. I finish and flush and put the lid down and I tuck my shirt in and a knock on the stall happens. And a deep voice says do you want company? I unlock the stall and the guy comes in I'm still standing and he's a few inches shorter than me but is muscular about 6' 180lbs or more, he says I need my cock sucked. I sit on the stool and run my hands over his bulgeand he says take it out. I undo his belt and his button and slide his zipper down. The guy is moaning and I haven't touched his dick. I pull his boxers down and his semi hard cock is next to my face. I look up at him and raise his cock to my lips and it hardens in my hand I lick the tip which is wet, circling it with my tongue as I look in his eyes. I'm in full cock shut mode now. I'm moaning and he's telling me to suck his fucking dick. I have his balls in my hand cupping them, running my middle finger between them. I take his cock between my lips and suck it in and out and he puts his hand on my head and I work my mouth down his hard cock, tracing the veins with my tongue. He's pushing his hips forward while holding my head. I bury my lips in his pubes feeling his cock in my throat. I put my hands on his legs now and try to push him back some. He's saying fuck yeah work that hot tongue. I'm moaning and you can here his sloppy cock sliding in and out of my mouth. I put my hand to his balls and they are getting tight and he says I'm going to cum and he pulls out of my lips and I open my mouth like a porn star and look up at him jacking him off in my mouth and the first ropes of cum were thick and the next few hit my eye and cheek and he grabs his dick and finishes stroking the last on my chin and tongue and wipes his cock around my face. Next he grabs my tie and wipes the head of his dick with a glob of cum on it allover my tie. He pulls his boxers up and I pull his pants up and he fixes his belt and button and zips up. Says thanks and washes his hands and fixes his tie and leaves. I walk to the sink and start washing the cum off my face and another guy comes in and looks at me. I finish washing the cum off and dry my face and hands. He's still looking at me. I think another load, but for some reason I leave. I'm hard till I get home and jack off. Went to that bathroom everyday but nothing happened again.
