Bondage involves many different sexual acts with the submission and the domination. You will enjoy watching BDSM as people are restrained with clasps and chains, where one person plays the master and one person plays the servant - she could be wearing a leash and walking around like a dog on all fours. BDSM sex can involve females being tied up with ropes all over their bodies - they get tied up with ropes on their boobs, ass, stomach, face, legs, arms and elsewhere. Take a look at how they are tied with ropes to a bed, a couch, the wall, the floor or other areas. BDSM porn is, actually, the use of restraints for the sexual pleasure of the people involved in the group sex orgy, or like the couples who cuff each other with the handcuffs. A hogtie is a position in which the wrists and ankles of the submissive person are fastened together behind their back with ropes or cuffs, and sometimes the model is wearing a ball gag in her mouth. Have a look at erotic massage or tickling. Sometimes the tied partner may tell the other free partner what to do to him. Certain terms for bondage exist such as breast bondage, head bondage, hair bondage and crotch rope.
