I was in my room at the airport hotel at Heathrow and just finished work and went to the room, showered and ordered for a room service as I was flying early morning to the USA. When I heard the knock on my room door I said come in as I left the door open after taking my shower and I was sitting on the chair watching the TV wearing my bathrobe. He was an old British short guy pushing the table with my dinner order. He gave me the bill and the pen to sign but the pen felt down so he bends on the floor to pick it up from under the table. Apparently he saw my crotch having a hard erection and coming out of the robe. Suddenly I felt his hands on my balls and my crotch was inside his mouth and he started sucking and toying it and toying my balls until I exploded in his mouth and fill it with my cum and this was my first experience with a gay guy.
