She froze. She was lying on their bed with her panties off, her legs spread wide apart, and vibrator plunged in her pussy. She had been surfing the Internet while Master worked on his computer in his study. Without thinking, she surfed to her favorite naughty story site and got into one of the stories there. Whenever Nora became aroused, her decision making invariably suffered. In this instance, she decided that rather than bother Master with her need, she would just quickly take care of herself. Surely she could get away with it just this once.
She knew she was caught. There was no hiding what she was up to, and she made no move to hide or cover herself.
"I'm sorry, Master. I didn't want to bother you..."
"Nora, you know better than that. Have I ever been so busy that I haven't been able to at least respond to your requests?" She averted her eyes while he lectured her.
"No, Sir."
"I might have given you permission to do exactly what you're doing, in fact. I've done that before, haven't I?"
"Yes, Sir."
"Do you have any mitigation to offer? Any reason at all why I should not punish you?"
She closed her eyes and gulped. "No, Sir."
"Everything off. Right now."
She quickly moved to comply: She tossed the vibrator on the bedside table and unzipped and removed the skirt she was wearing that had been bunched up around her waist. She then pulled her top off over her head and unsnapped the catch on the front of her bra and pulled it away from her breasts and off her arms.
He turned and went to the closet and came back with two arm cuffs and a spreader bar. He toss the bar at her feet and she obediently put her hands in front of her. He put the cuffs on her wrists and hauled them up over her head and clipped them to a ring in the headboard. He then resolutely strode to the other end of the bed and attached first one ankle, then the other to the spreader bar. He then grabbed the bar and yanked it towards the bottom of the bed, roughly stretching Nora straight.
He went back to the closed and returned with a small leather tawse. Nora shuddered. This particular tawse was made of a lighter, more flexible leather. He had bought it with one particular use in mind, and referred to it as the "pussy tawse." She saw him with it and whimpered in anticipation. Deep in the recesses of her mind, she knew she could stop him with her safe word (it was "Mercy"), but she also knew that she felt guilty and needed his punishment to ease her guilt. At the same time, her pussy was still wet from her earlier efforts, and continued throbbing from the thought of his punishment.
He sat on her right side and leaned towards her, wrapping his left hand over her. In this position, her only view was of his back. She felt the tawse rest on her pussy, and then a moment later, felt an explosion of searing pain and screamed. She strained against her bonds, only starting to relax when her lungfull of air forced an end to her scream of pain. She gasped and started sobbing, her vision clouding from the tears forming in her eyes. The tawse flew against her again, and she screamed again, her muscles tightening. His next stroke was against her right inner thigh, wrapping from the front almost all the way to her bottom. Her screams were now briefer now, mixed in with sobbing.
