If your libidinous mind can imagine it, there’s probably already a term for it
X-cross (n) a piece of equipment popular in BDSM dungeons that is used to restrain a submissive’s ankles and wrists in an upright spread-eagle position.
The domme tightened her sub’s limbs to the X-cross, leaving him bound, helpless and incredibly turned on.
Though the X-cross, also known as a Saint Andrew’s cross or saltire, is quite common in BDSM dungeons around the world, the equipment gained mainstream notoriety in the 2011 erotic novel Fifty Shades of Grey, when it’s used to secure the hapless Anastasia Steele. This piece of BDSM furniture is usually metal or wood and comes in the shape of a vertical diagonal cross. The subject’s wrists and ankles are splayed and tied to the four posts, allowing the subject to be teased with whips, flogs, crops or the domme’s bare hands. For those craving a more intense experience, some X-crosses can even be made to spin on an axis. (Who wants to play Wheel of Fortune?)
The image of someone trapped on a diagonal cross has Christian origins, as it’s believed that’s how Saint Andrew, the patron saint of Scotland, was martyred. When he refused to stop spreading the teachings of Jesus Christ, he was sentenced to death by crucifixion. Believing he wasn’t holy enough to die in the same manner as Jesus, he asked for his cross to be turned sideways. Centuries later you have a brutal torture device that has been repurposed for both pain and pleasure. Join & Satisfy Your BDSM Fetish here!
