Babysitter is waiting on all fours to get fucked

When he gets home, this man discovers that the new nanny is waiting for him on all fours and does so with his eyes covered in a morbid way, so his uncle can have sex with her without saying a word. It was all arranged by the man's wife, who is a very liberal woman and wants her husband to have fun while she travels for a few days. So the wife tells the nanny that in addition to taking care of the children, she will have to let herself be fucked by her husband as much as she wants, something the man does as soon as he gets home.
