But first she wanted to ensure she kept her control over him. She had just the thing to do it, bought from one of those mail order Internet sites and kept hidden in the bottom of one of her drawers for the last few weeks.

She rummaged around under the clothes jammed into the drawer and found it. Four tough metal rings held together by leather straps, with a fifth slightly larger ring set further away from the others that opened and locked shut. Quickly, touching him as little as was absolutely necessary to position it properly, she attached it firmly round his manhood and locked it into place. Perfect, she thought. He could pee with it on, but there was no way he could be unfaithful or even relieve any frustration himself. In fact, there was no way he was going to become hard with that fixed on him – the rings were far too small to allow an erection. They might allow some movement she thought, and she wondered whether he would find it uncomfortable or even painful if be became excited. She hoped so.

Perhaps she should have bought the one with little spikes on the inside of the rings.

Perhaps she would buy it.

She looked at him lying there, still completely under her control. He seemed to be asleep, exhausted. Time to wake him up. She turned on the light.

She knelt over him again, and slowly lowered herself to within an inch of his face.

"Wake up," she said softly, "Look what I’ve got for you."

He opened his eyes and looked, immediately starting to stiffen. She saw his startled look as he filled and pressed against the metal rings, and she laughed. "That should stop you misbehaving," she said, "Now get off to work and don’t be late home."

In the bathroom he examined the device restraining him, but there was no way he could remove it without cutting the metal or the leather straps. And it would take something tougher than a pair of scissors to get through either. He dressed and left for work.

He had an uncomfortable day. The rings and leather straps rubbed on him as he moved, and each time this happened he started to stiffen only to find himself held back and restrained. The larger locked ring was pulled forward painfully as the smaller rings filled and strained. Over and over again this happened – it took only the slightest stimulus to start it off.

He arrived home early.

"You got to take this thing off me," he told her.

"I will," she said, "Show me."

He didn’t need any encouragement to drop his trousers and pants. She looked at the restrainer critically..

"You’ve been naughty, " she said accusingly. "You’ve been getting hard without my permission."

"I can’t help it," he replied, "Just take it off. Please."

"OK. Bend over the back of that chair and I will take it off. I promise."

He bent over the back of the dining-room chair she indicated. She produced two lengths of chord and started tying them round his wrists. He pulled away.

"Do you want that restrainer removed or not?" she asked angrily.

He leant over the chair again, not resisting her this time as she secured his wrists to the legs of the chair. Then she tied his ankles to the back legs of the chair, making sure he could not move.

She produced a small key, and with a little difficulty removed the locking ring and slid the device off him. His manhood sprang forward rigidly.

"Well," she said, "That’s bigger than I’ve seen it for a long time."

"But," she went on, "You still need to be punished for misbehaving – for even thinking about misbehaving without my permission."

She left the room and returned with a riding crop which she waved in front of his face.

"A dozen strokes of this will do for a start."

She raised the crop and brought it down across his buttocks, not too hard. He flinched, but said nothing. Gaining confidence, she put more force into the second blow, and increased the power again and again as the crop struck his buttocks repeatedly. As she reached the twelfth stroke she had promised, he yelped audibly with the pain.

"Poor little man," she said, "Did it sting a little?".

She put her hand on his buttocks and stroked them, almost affectionately. With her other hand she explored in front of him, feeling the hardness still as large and firm as it had been when she released it – even harder and firmer, she thought.

"I believe you enjoyed that," she said.

He started to protest that he hadn’t enjoyed it at all, but she shut him up. "Let’s see what we can do with this," she said, giving him a squeeze.

She had another device she wanted to try, something else she had bought from that Internet site. A very special glove. This glove was made from thin rubber, but on its palm and on each finger and thumb were hundreds of tiny metal spikes. Packed closely together, the spikes would merely tickle if run gently over human skin, and holding any part of the body while wearing the glove would produce a sensual feeling rather than any prickling or pain. But gripping hard or smacking would produce a different effect altogether.

She put on the glove, and held his manhood gently.

He squirmed, not in pain but in pleasure at the feel of the glove on him. With her other hand she gently slapped his buttocks, moving the gloved hand up and down him as she smacked.

She could feel his movement, and his urgency for her to rub him to a climax. She moved her hand up and down faster, smacking him with the same rhythm. He was approaching climax – and then she squeezed, hard. At the same time she slapped his buttocks as hard as she could repeatedly. The little metal spikes suddenly stopped feeling sensual and dug deeply into his flesh. They were not long enough to draw blood, but quite long enough to cause pain. Slowly and deliberately she squeezed as hard as she could and moved her hand up and down twice. He let out a shout of real pain, and his hardness subsided. She released the pressure.

"I thought you needed some satisfaction?" she asked, tauntingly, "I’d better start again."

He was breathing heavily, and seemed unable to answer. Slowly and gently she teased his manhood into hardness again, rubbing smoothly and starting the gentle rhythmical smacking on his buttocks.

Again, as she increased the speed she could feel he was nearing climax. And again she squeezed hard, slapped hard, and gripped until the hardness subsided.

Ten times she repeated this, and saw he was covered in sweat and his legs trembled, barely supporting him. If his wrists and ankles had not been secured to the chair she was sure he would have been unable to stand.

"Please, please," he begged, "You just got to let me.....".

"Hmm", she said thoughtfully. "All right, I’ll finish it off. But I’m going to do it the way I want. Agreed?"

"Yes, yes. Please." At this stage, she thought, he would have agreed to anything.....
