OK, so this is not a spanking picture per se, but stay with me here. The excellent wooden leg-spreading ankle stocks shown in this picture (which currently grace the well-stocked dungeons of the deliciously pervy folks who run the Hogtied bondage pay site) would be a fine toy for any spankos.
See that iron ring on the front of the block? Just untie her hands from overhead and tie them close to that ring – she’ll perforce stick her lovely bottom out at you until you tire of spanking it. Which isn’t going to happen in this fiscal year….
