Interracial sex studies might improve hubbies brain injury

This rehabilitation institute has conducted sex studies where patients with brain injuries might recover faster if they are forced to watch their gorgeous, big tits wife having hardcore sex with a studly, black caretaker. It's also become a service they provide for sex starved wife's, with neglected pussies due to their hubbies mental condition. The treatment starts out with the wife giving the male nurse a blowjob, then he fucks her wet, shaved pussy in as many sex positions he can can up with. They have a hidden camera filming the husbands reactions! Unfortunately it captures an image of a still very confused hubby, who has no idea what's going on. Naturally his wife couldn't be happier, cause now she gets to come back next week and try out this very gratifying, self serving experiment once again.
