Some years back I was in a hostel in Singapore. The room of 4 double bunks was mixed genders.
I had just checked in, and entered the room. The room was fully occupied, but all had left for the day, except one Filipino guy who was packing his things, ready to check out. It was about mid-day.
I started talking to the Filipino guy, and I said I was hoping my hostel mates would be all men. He asked why, and I explained I prefer to sleep naked.
I noticed he seemed interested as he took more than a few flurtive looks at my crotch, so I steered the conversation to sex. I told him it is not the biggest but thankfully, it works. He was definitely interested by now.
I started to undress to my briefs, as though I was going to climb into my bunk to catch forty winks. The Filipino guy grabbed me, I got hard, and very soon, he was leaning, facing the door to prevent it from opening while I dropped his pants. I entered, and I was quite surprised he was smooth and moist inside, and rather warm too!
I think he was excited by the risk of being caught by one of the hostelmates returning to the room. He pushed his ass towards me, but at he same time he said, "Oh no, what if someone comes in?"
I too, was nervous that I might be caught in flagrante delicto by the cleaner, so I stopped after a few pumps. I did not cum, and I think he did not expect me to erupt inside him either. After these few stolen moments, we broke apart and dressed ourselves.
He then picked up his things, and left the room to check out. I don't remember if we introduced ourselves (I knew he was Filipino from his accent) but it was certainly a quick session. After he left, I dug out my towel and went to the shower to clean myself and jack one out.
