Busty tart Brooke Haven is just feeling so damn horny and she just can't get herself off! In desperation she goes to see a sex therapist, who takes one look at her and knows exactly what she needs. This guy has been building hardcore fucking machines in his backroom and Brooke looks like the girl to try them out. Leading her into his chamber of pleasure, he orders her to remove her clothes and to sit on a strangely shaped chair with her legs spread and her feet in stirrups. Brooke looks slightly scared when he wheels in a bulky machine, with a huge plastic cock attachment. She soon begins to feel the pleasure as it piston-fucks her.
