This device is perfect for suspending slaves upside down. It keeps their legs spread so that you can observe their wettness as you whip their back, tits, ass, and pussy. It is also a perfect position for fucking a slave's mouth. Just don't leave them upside down too long. My wife looks so helpless when suspended. She was in this when she agreed to be my slave for life. She was in this when she agreed to have "Whore" tattooed on her pussy. Just add a pulley system and a quality pair of leg cuffs with strong locking rings.
