I think this is actually pretty common! It happens to me all the time. I’ve had a few of very hot airport hookups in my life. I think it’s part of the idea of seeing so many new people all from and in different places. I’ve had hookups with at least two straight guys in airports and one who I’m not sure what his sexuality was—maybe bi.
On one flight I was seated next to a guy who was in classic grey sweats and he was obviously very horny, adjusting himself most of the flight. He was driving me crazy because I could see how much meat he was moving around in there. When we landed, we both went directly to the nearest restroom and then stood next to one another at the urinals. He hauled out a monster cock and then looked over at me with a question mark on his face. I nodded my head to signal that we go to a stall. I went in and he followed about 30 seconds later. I sucked that guy’s BWC like my life depended on it until he shuddered and blasted buckets of cum all down my throat and all over my face. When he withdrew his cock from my face he slapped me with it, then spit in my mouth. It was so fucken hot. He told me he still had to piss, so I opened my mouth and served this stud as his urinal. I didn’t think he would ever stop pissing, and I could hardly swallow it fast enough. He shook it off in my face/mouth and then I licked and sucked his fat, bulbous cock head clean. He gave me one last slap with it on my chin, turned and walked out. I’ll never forget it!
