Here exists an extreme bond found only in the world of SM ism. This connection runs deeper than that of parent and child, lovers, or friends, as scars etched into the body guide the two into a new, alternate realm. The reason intense, hardcore play becomes possible lies in the depth of this bond. Acts involving pain transcend the newly formed boundaries between them. While enduring the pain, the receiver takes steps forward into a world shared by only the two of them. Each step deepens their relationship further.
