That Lady in Rope (2013)

In several interview segments, busty blonde Carissa Montgomery explains how she became a bondage model and demonstrates her enthusiasm for the medium in several different scenarios. Later in several vignettes, a bevy of buxom beauties are securely bound with vibrators roped securely to their nether regions so they can achieve unwanted but massive orgasms. In the final sequence two handcuffed and gagged ladies compete for cash prize, the winner being determined by whoever has the most orgasm triggered by a vibrator in a set period of time.
