John’s comment:
The whole movie was structured around how to make this scene work, Nacho Vidal and Melissa Lauren, with Rocco Siffredi and Katsuni as only observers.
Melissa collects her reward, Safado, as played by Nacho, This sex was the centerpiece on my story for the Safado movies. Katsuni and Rocco are there to help create the erotic debauchery that is this Safado update. Melissa Lauren is slapped, choked, spit on, squirts, and is analized for the sexual fulfillment of Melissa, as well as the creation of a spectacular update.
