Bondage is an act of restraint meant to prevent someone from doing what they would want to do. that is not an act of love. People can and do get so twisted in their thinking by demons that they begin to like what is not nice. some people get a thrill (demonic) from being whiped and beaten, from being humilitated , from being degraded. Deamons are always their to try and drag you down to a lower level and they make it enjoyable. demons make sin pleasurable. handcuffing your mate and having sex with him or her in that state is degrading and perverted but it isnt extreme. its a first step down a road some demon is trying to take them. a demon will make that sort of sex act enjoyable for a while then he will take some of the joy away causing that couple to go deeper, next step the demon will suggest might be a little flaggelation. 'oooooooooooooh thats good more give me more I like that.' they might say. pretty soon though thats not enough cause the demon will withhold some of the joy they were experiencing doing that, then the demon will suggest something else. like mutulation, then next maybe a little branding, then next maybe a little ear stretching, then next rings in your tounge and nose and chin an d navel and nipples, then next hanging upside dwwon in a basement dungenon. then next maybe sacrifice to the demon, then next death.
