".....When he’d regained consciousness after passing out from that searingly intense orgasm he’d had while he’d been strapped to the wall, he’d found himself lying on the bed here in this suite. The first thing he’d noticed when he’d opened his eyes was his reflection in the mirrored ceiling. Staring back at him was a good-looking punk boy with a short blond mohican. All he was wearing was a couple of leather wrist bands – locked on – and a very strange-looking pair of shorts. Each of the leather bands had a slight lump on one side, but apart from that they were featurless. The shorts, however, were very odd – they appeared to be made from thick rubber, and they were padlocked onto him at the waist and at each leg. They fitted very tightly, molding to the contours of his hips – but the most extraordinary thing about them was the crotch: the part covering his cock and balls was solid and rigid – and it was enormous. It protruded perhaps eight inches from his body in a rounded pyramid between his legs. Lying there on the rubber-covered bed, Craig looked down at himself and shook his head in disbelief. “What?” He said.
 He lowered his right arm to feel the front of the shorts – and yelled in sudden pain as a very unpleasant electric shock shot through his balls.
