I watched that movie a long time ago and its stuck in my head.

It was not in English.

Set in remote country/ woods.

There were cabins in a row with one sex worker in each cabin and lines of soldiers in front of each cabin.

Main actress was also one of them and famous among soldiers.

Commanding office was not involved in sex but ends up having sex with her in his office and then feels jealous of her when she is in cabin serving soldiers..

Any idea guys? I’m searching for a long time.
