Una erección preestinada

Doctor Farnese is contacted for an emergency, one of her patient's cocks no longer stands up straight. He therefore decides to adopt an innovative technique, the "transfer method" which consisted in making the patient's friend's cock stand on end in such a way that the energy is then transferred to the sick friend. well, what can I say, the method works! Max and Lena set no limits to their perversions... Lena wants to get fucked in the middle of a river!
