I got the chance to capture some couples a few weeks ago. I also kept some hidden recorders in other parts of the hallway without success.
First couple: I had the chance to see them at the reception. It was almost 22h, they had just a small backpack. They were between 20 and 23. For the way they spoke at the reception I had the impression it was a "tinder" date and they stopped in the closest hotel from their meeting point. I got this impression for the late check-in without reservation and some "sorrys" from her at the end of the first round.
He was really tall and skinny, blond long hair. She was just the opposite, super small (155cm max), brunnete long hair. Her body was just ok, not fat but also not something amazing. It took literally less than 4 minutes to begin the action. I wait just 3 minutes before going to their room to see if there was action, and she was already breathing deeply.
That happened at 22h... at 00:20h they did another round, but I captured that one almost at the end.
The other couple was on my floor, in front of my room. When I finished to do the rounds, I went back to sleep at 2:00 when I heard what I thought were kisses... and indeed, were kisses but between the woman and his dick. What you hear is a blowjob and in some part she is asking him to stay silent because is late. Couldn't see them the next morning to give a description.
Hope you enjoy.
