Dr. Gigi Allens turned her love of cock into a rewarding career studying male arousal, and her latest project is trying to cure erectile dysfunction. She brings in two subjects who are incapable of arousal, and shockingly, subject 2 (AKA Mick Blue) starts getting hard as soon as he catches a glimpse of her beautiful big fake tits. Astounded by the unexpected boner, Gigi goes in for a closer look and starts sucking and stroking that fat cock with the ease of a trained professional. Mick fingers her tight pussy until she's nice and wet and then he fucks the busty blonde hard. Finally, he gives the dirty doctor a nice big facial, all in the name of science.
