A little boy saw his mother in a brothel

The young guy gets into the train, some of which is allotted to the brothel. Not knowing that he is looking for a toilet and enters a closed area. Looking at each compartment, he sees how lustful women and his mother jump on the heated males or happily substitute their cracks for them. He goes further and gets into the compartment, where the rest of the prostitutes are preparing for their exit, and they begin to seduce the Maltz, for the sake of the joke.
