I was in the back row of a plane once, alone with a 14 y/o boy. I was 25 at the time.
He was cute, so I started rubbing my crotch and stroking my cock through my jeans — ‘absentmindedly’. He noticed and started doing the same thing. We spent the rest of the flight watching each other rub our boners, no one else saw what we were doing.
When we landed, I asked him if he wanted to finish it, so we went to the handicapped bathroom where he gave me a handjob and I gave him his first blowjob ever.
His small hand made my cock look huge. My cum shot all over the floor, and I got a lot on my knees when I blew him, but I didn’t care.
I watched his parents pick him up after baggage claim. I felt kinda guilty, but it turned me on even more to know that they had no idea my cum was still on his hands and his was in my stomach.
