Of course, at 19 Diana was far too old to actually believe in Santa but it was something of a family tradition to pretend that she did, and in a small way it helped to keep the magic of Christmas alive for all of them.

That's why, a little after midnight on Christmas Eve she put on her robe and pink fluffy slippers and crept downstairs with a bag full of presents in her hand.

As she reached the bottom step, Diana froze. There were distinct sounds of movement coming from the front room - the creak of a loose floorboard, the whisper of cloth against cloth, and the faint jingle of the tree decorations as they were disturbed. They were being robbed!

A part of Diana's mind knew that she should be terrified, that she should run and hide, shout for her parents or call the police, but that inner voice couldn't compete with the rage and indignation she felt. How dare they rob her house, and on Christmas Eve of all days??? She dropped her bag of presents and stormed into the room to confront the thief.

She stopped dead in the doorway. He didn't look like a burglar. In fact he looked rather like... but no that would be ridiculous. The bright red suit and bushy white beard were obviously part of some sick disguise, a way to trick any youngsters that caught him in the act. Besides he wasn't anywhere near fat enough to be the real thing.

Diana continued her march into the room, and the robber turned to look at her. She opened her mouth to shout, to order him to leave and demand an explanation, but before she could get a word out, he spoke first. "Ah Diana. I wondered if I might see you tonight. You always were a good girl."

His voice was deep and soothing, with a hint of supressed mirth lurking beneath the surface, but it was his words which threw her off-balance. The shout died on her lips, replaced by a hoarse whisper "Who are you? How do you know my name?"

He laughed, a deep rumble in his chest. "You know who I am, just like I know everything about you"

There was something about the way he said that "everything" that brought a blush to her cheeks. Her mind drifted back to the dildo hidden under her bed, and what she'd been doing with it while waiting for the rest of the house to fall asleep. Surely he didn't know about that, did he?

His next words seemed to confirm her worst fears. "Yes Diana, everything." There was a twinkle in his eye as he spoke. "You used to be so well-behaved. A letter every year, milk and cookies left out on the side, even a carrot for my friends. But now...well you have your own little friend to play with don't you?"

The tone of his voice made Diana think that she had somehow let him down. "I'm sorry. I just..." her voice tailed off. What exactly was she apologising for anyway? Being horny? Enjoying her body? There wasn't anything wrong with that! Besides, everyone did it.

The visitor laughed his deep comforting laugh again. "You've been on my naughty list for a couple of years now haven't you? But don't worry, I still brought you something." He put his hand into a coat pocket and pulled out a small package, wrapped in red and gold paper and tied with a delicate silver bow.

"Um thank you" Diana said, taking the parcel from his outstretched hand. She examined it curiously. It felt like the present was held in a slim cardboard box, four inches long and maybe an inch wide. When she held it to her ear and shook gently, there was a faint rattling sound, as though whatever was inside was moving against padding.

"Go ahead and open it" He said generously "Technically its Christmas already"

Diana barely hesitated before undoing the ribbon, peeling back the paper and revealing a plain cardboard box. She didn't know what to expect but when she opened the box, she knew that it wasn't that. Nestled on a bright pink pillow, there sat a shiny silver bullet vibrator, around three inches long and with a single bright red button at one end.

She took the toy from the box and held it up doubtfully. "Is this... what I think it is?"

Santa nodded. "Do you like it? Bad girls are always so difficult to get right"

Diana pressed the button and the room was filled with a high pitched hum. She quickly turned it off again. "I do! Thank you! But... isn't this a bit... inappropriate for you?"

He took a step forward and placed a hand on each of Diana's shoulders. "You're right, it would be inappropriate for me. But for you, I think its entirely suitable, don't you?"

Diana blushed. She had to admit he was right. She was already imagining how it would feel against her clit, and getting turned on at the thought. It didn't help that with him standing so close to her, resting his hands on her shoulders and looking straight into her eyes, she was acutely aware of just how masculine he was in the flesh.

For the first time she properly looked at him, seeing the man rather than the stories. He wasn't the "jolly fat man" she'd grown up reading about. His build was that of a manual worker, someone who had a physical job and did it uncomplaining day after day, quietly building muscles. His bushy white beard wasn't a sign of pending infirmity, but rather of wisdom and experience. His humour was there, but it held a dark edge, hovering beneath the surface.

Diana had always harboured a secret fantasy about older men, and that's how she was seeing him now. She bit her lip at the images that flooded her mind with that realisation. This wasn't just any older man, this was Santa himself! She couldn't really want to do those things with him, could she?

He was still looking at her, waiting for her to reply. His blue eyes bored into hers, as if reading her mind. For all she knew maybe he was, but if so, he didn't flinch from what he saw there. Diana had to say something, anything, to break the moment. "Can I... try it?"

"Of course you should. Its yours now after all" he answered.

Santa didn't release her shoulders or lift his gaze from hers. Did he... did he mean that she should do it now? With him standing right there? Diana didn't speak the question out loud, but still he nodded and smiled encouragingly as if he'd heard every word. Diana swallowed, suddenly nervous, and with a hand which only shook a little untied the belt on her robe, letting it fall free to reveal the cream coloured nightgown she wore underneath.

For the first time in an age he broke eye contact, unashamedly and openly eyeing Diana's cleavage as it lay exposed by the low-cut line of her nightgown. She licked her lips nervously, still uncertain whether she could actually go through with this. He seemed to understand her hesitation, and hooked his thumbs into the dress' shoulder straps, easing them down her arms until it fell to join her robe on the floor.

Diana already knew what would happen next. He would wrap his strong arms around her, crush his lips against hers. Then his hands would begin to wander. She was so certain of it, that when Santa took a step backwards she almost over-balanced. She was still waiting for him to make his move. Instead, he simply stood and waited, only his eyes moving as they admiringly traversed her naked body. His message was clear. The choice was hers, and he wouldn't make it for her.

For the first time, Diana truly felt what it meant to be empowered. She could pick up her nightdress and robe and return to her bedroom if she chose. Or... she could follow through on her unspoken invitation. When she looked at it like that, the answer was clear. Only one of those options held any appeal to her. She was nervous- who wouldn't be? - but she acted as she always did when she felt that way. She put on a front of pretended confidence.

Diana turned and walked to a waiting chair and sat, before gracefully stretching one leg across each arm, displaying herself almost proudly. A gentle hum filled the air and she dropped the hand holding her vibrator into her lap. At the first contact with her clit, Diana moaned loudly, uncontrollably. It was far more intense than she would have thought possible.

She tried again, this time positioning the tip slightly higher. The toy still sent its powerful pulses through her clit and it still felt good, but it was no longer so overwhelming. Cautiously she moved it around, noticing how the sensation changed as it brushed over her lips.

As Diana grew more accustomed to the toy she grew braver and returned to her clit. Again she couldn't avoid moaning in pleasure but this time she didn't let up and kept going with a gentle pressure, her moans building to a crescendo.

She looked up to see Santa watching her avidly, almost hungrily. Sometime during her performance, his trousers had fallen to his ankles, his hard cock proudly on display as he slowly stroked up and down the shaft with one hand.

Diana couldn't take her eyes from him. She'd seen cocks before of course, but never one as long or as thick as this. The sight sent her into a frenzy and without hesitation she drove the vibrator deep into herself, thrusting in time to the movements of his hand.

The stimulation proved too much for her and she cried out as her orgasm crashed through her like storm, the blinding flash of lightning as it hit, the rolling thunder of the aftershocks as her body melted into the release.

"I always knew you were a good girl!" Santa said. "Same time next year?"
