Two couples of swingers frolic in group sex

Somehow, two guys who were swingers and offered a friend to make an exchange of wives for sex were written off to the dating site. And when two couples met, they did not break through the couple, but decided to have sex together in the same room. Wives and husbands were interested in watching from the side of how to fuck with another person, while enjoying sex with a lover or mistress. The boys and the girls got such a cool group orgy that the fornicent girls and lustful guys decided that they would repeat such a hot experiment more than once.
