Couples' porn company Sweet Sinner delivers stock characters (Stepmoms! Exchange students! Escorts! Swingers! Strippers!) in surprising situations so that couples are both titillated and unthreatened. A division of Montreal's Mile High Media, Sweet Sinner was founded in 2009 and rose to be a market force with the arrival of Porn Valley veteran James Avalon in 2011 directing most of the titles.
