Back Door Man is the NSFW tale of a male escort recalling his crazy night of work. Working your way through each of his three 'jobs', there are multiple outcomes to find for each which determine what kind of ending you will eventually receive.

Created for the TIGSource Adult/Education Compo, the bulk of the game involves making conversation with people, with your answers affecting how they respond to you. It will only take you around 5-10 minutes to reach the conclusion, but you'll want to play through it multiple times in the hope of receiving the 'good' ending.

Be aware that there is swearing and nudity (as if you hadn't already guessed). Grab it off the TIGSource forums. (direct download link)
