I had the opportunity to do some captures. I was in a hotel with a nice setup which should bring some intimacy to do the magic.
First couple (19.32h file) were ready into action just when they arrived back from the city. I didn't hear do the check in, so probably they stayed the night before. You can hear almost every word they say and the nice sound of the blowjob she gives him. Unseen couple and unfortunately I didn't catch anything else that night from them. I would say 30-35ish.
Second couple (02.32am file) got my attention way earlier when I just arrived the hotel. After going to my room, I did one round and they were going at it just at the end, couldn't record anything but I marked that room as a follow up. I was really waiting for them to come back at night, and they did at 2:30 aprox (I was listening to another room, too quiet that I don't share that file because you here almost nothing, not worth it), just after entry in the room and going both to the toiler, they started with the kisses just at the same time that the other couple finished. Unseen couple as well. My guess is they were around 35-40ish.
This hotel has potential, so big chance I will come back sooner or later.
Hope you enjoy. Feel free to enhance or filter both files.
