Just to tell you an old story which happened to me many years ago, during the summer 1993 (a long time ago...).
At this time, for my job, I've needed to go to Arcachon, a little town near Bordeaux and on the Atlantic Ocean shore.
I'm stayed there six weeks, from mid-july until the end of august. I've rented a room in a cheap hostel. Unfortunately, it seems that it doesn't exist anymore

It was during summer hollidays so there was a lot of people, frenchies and foreigners, who came for sunbathing, swimming, etc...
It was a little and old hostel, but cosy, with only a dozen of rooms on 2 floors if I remember well.
Walls were pretty thin and there was at least 2 centimeters beetween the floor and the lower part of the doors, so it was nearly impossible to be discreet, but I've understood rapidly that nobody cares...
I was the only one to stay for a such long time, others rooms people stayed for only few days, generally 1 or 2, rarely more, but all rooms were occupied at any time.
Now, I regret to have not thought to record all the "sessions" I've heard during this time.
Actually, EACH NIGHT, there was at least one couple who fucked, and often several couples in different rooms, in the same times or not. It was a festival !!!
All began generally late in the evening, I would say about 23:00 PM and later.
I'm sure that if I've done it, I would have dozen of hours of recording. But, at this time it was far of my mind. Silly boy...
I remember a funny case, in particular.
It began in a room near mine. In fact, I have been awoken by their noisy arrival late in the night. They began rapidly to fuck after closed the door and it lasted 2 hours,
nearly non-stop. I don't know how many times the girl and boy enjoyed, but I was puzzled by her endurance and very impressed by the endurance of the man, too.
The girl moanings were really hot and sexy, but not so loud, the man was more quiet and they were not very talkative.
Generally, it lasted not so long. But, here,I was totally amazed by the duration and the continuity of the action.
I wondered how a man or a woman could be so ""athletic" in sex.
Finally, the next morning, I've had the right explanation. In fact, it was a threesome, two men with a girl. I've supposed that when one was tired the second take his tour and so on... (naughty lucky girl !!)
I didn't really observe the two guys but they looked in their mid twenties and relatively good-looking, but the girl, in its mid twenties too, was a stupendous hot number, with blond hairs, pretty tall, a very cute silhouette with big and round firm breasts, slim waist and a delicate face, a little triangular. I'm not sure but I think she had blue eyes.
She was outstanding.

But, so, they were bikers and they stayed for only one night, I've seen them only in the morning when they prepared themselves to leave.
This confirm definitively that, during summer hollidays, there is a lot of people which, in a good atmosphere, are more relaxed and lose more easily their
inhibitions and common decency !!
