Mistress Cat is looking upon you benevolently, and has decreed that members of the SlideRulesYou forum* can hire her fully-equipped private dungeon for the special rate of £30 per hour. Facilities include a St. Andrew’s Cross, whipping post, cage, suspension hook, A-frame, and whipping bench with accessories (which include a leather sleep sack, ball weights, nipple clamps, collars, paddles, crops, canes, floggers, cuffs, shackles, leather straps, Violet Wand, spreader bars and rope). It’s close to Gatwick, so very convenient to get to via public transport and major roads.
*update: I ditched the forum a while ago, but mention me and this probably still stands.
