Underbelly is based in Paris with all scenes filmed underground. Each scene embraces the city’s dark and erotic reputation that stems deep within. The keyword here is deep! In the opening scene we are introduced to Antonio and Stephan who show what its like to slam down a screwdriver, and we are not just talking cocktails. From sexting on cell phones through to fucking like animals in the wild, the scenes that follow bring filthy hot sex back to the small screen.[
