There was even a fourth opportunity, but I didn't go to the 'act of recording'. At a certain moment, there was laughter on the hotel corridor of multiple young girls' voices, and as they were passing my room, I saw through the peephole that it were 3 nice black girls and a young guy. They were together with one of the hotel guests, telling them: "hush, it's a surprise". At that moment I kind of had an inkling that it was actually a party of hookers going to their destination

And yes, not even ten minutes later, two girls were heavily moaning, and from the slapping sounds coming from the room, the two were clearly going doggy style while the third girl was shouting: "Yes, teach them a lesson!!" and sounds of asses being slapped

Anyway, one great pandomium, and I could all hear it from my room door. For a few seconds I was considering to gather my courage and go down the corridor to their door, but luckily I didn't. As the party probably took a bit long, all of a sudden 2 shady eastern-european types came out of the elevator, I quickly closed my door, and they went down to the room after which there was heavy knocking on the door. First there were some apparently angry words, than they started laughing in a typical pimp-ish greasy way, and than they came back to the elevator while the fucking party resumed.
After about another quarter of an hour, the three black girls and the guy passed my room again, laughing and shouting at each other, and off they went.
A pity I didn't record, but I don't know what would have happened if I would have been trapped between the room and the pimps all of a sudden coming in
Anyway, 4 great fucks on one evening in the same corridor, it's not a bad record. Very often, it's much less, even in the 'romantic' boutique hotels I'm always staying for work.
