Lisa loved her bed. Not in a weird way, just in that it has always been there in her life. She grew up in that bed, cried in that bed, laughed in that bed. She had her first kiss there. A large and ancient thing handed down from her late grandmother when Lisa was only tiny, it was built solid, with four thick wooden legs, each with a round bedknob on top. A steadfast companion throughout her life.
Lisa herself was a pale, thin girl, with red hair and a smattering of freckles on her face and upper chest. She wasn't hugely confident in her appearance, but what nineteen year old was? Standing at 5'8", with small, perky breasts and hips that had a decent sway as she walked, she'd still attracted a few boyfriends over the years. Nothing that you'd call a serious relationship. She still hadn't had sex yet, and had a feeling she was getting a reputation for being a prude.
"Although if they saw what I was into," Lisa thought, "I'd have a much different reputation..."
Just then, Lisa's mother knocked on the bedroom door.
"Are you decent?" She said.
"Yeah come in," replied Lisa, "When are you guys off?"
"In a minute. Your father and I are catching the train in about twenty minutes. We'll be back Sunday evening, there's plenty of food in the house. Don't forget to feed the cats. Have you got everything you need?"
"Yeah, it'll be fine, you're only gone two days."
"Okay then," said her mother, "we better go. No wild parties! You can have a friend over if you like."
"But no boys in the house while we're gone!" Lisa's father shouted, from downstairs. "I can sense them!"
Lisa rolled her eyes. She knew her dad didn't need to sense anything, as there were security cameras set up near the front door. He didn't have to worry anyway, she had a much different plan for this weekend.
"Ha ha," she said, dryly, "I'll be good, you have fun!"
"Bye sweetie! Phone us if there's a problem!" her mother shouted as they hurried out of the door.
Once the front door was closed, Lisa locked it behind them then scrambled back up to her room. Oh she had plans, all right. She pulled a trunk out from under her bed and unlocked it with a key she kept taped to the bottom of her desk. Inside was a whole host of BDSM and fetish equipment. Gags, rope, cuffs, blindfolds, clamps, little jiggly things, and a small collection of dildos and vibrators. Not to mention condoms and lube... just in case, she told herself.
She laid out a few choice items on the bed, ready for an afternoon of fun. Despite her nervousness stopping her from ever quite getting around to having sex, she was a proficient masturbator. This had crept into the world of self-bondage and masochistic tendencies, too. The internet had helped with that. Nothing got her quite as excited as being helpless and humiliated, in the privacy of her own room.
Lisa looked at the end of her bed and shivered. She had been psyching herself up for today for some time. Many nights of solo passion she had fantasised about this. She had researched online for techniques, and bought larger and larger dildos in preparation. Her biggest one was a struggle, a 2.8 inch diameter 8 inch shaft made from soft rubber. She could manage it, just about, but today would be something different.
The house was warm, but she still had goosebumps as she stripped off her clothes. Her panties were already wet from anticipation, and she blushed hotly. What sort of reaction was that, she asked herself. Blushing while alone? For goodness sake. Never the most tidy person, the clothes ended up in a heap on the bed. She grabbed a few items from her prep, and headed into the bathroom.
As she sat on the toilet for a pee, she put on a dog collar. A lot of the toys she had were things she had found or made, although a few were bought specially from certain websites. This collar was wide and made of leather, with small studs all around. It was a proper dog collar, so she had punched extra holes into it to make it fit. It had a shiny tag on it with "LISA" engraved into the metal. Lisa's family didn't even have a dog, unbeknownst to the woman at the petshop who had sold her it.
A small padlock went through the buckle, stopping anyone from removing it without the key or destroying the collar. Next went on the ballgag. It was a full face harness one she had got online, and wasn't cheap. She had worn it plenty of times in the past, and it was her favourite. Lisa had managed to wear it for a good few hours before her jaw really ached, but once all the little straps and buckles were done up she was effectively muted. This one actually came with a series of small padlocks, and she locked each one in place.
Once done, she stood up and looked in the mirror above the sink. Her wide eyes, framed by the face harness, stared back at the strange young thing in the mirror. Pale and freckled, with reddening cheeks, her face was a picture. Her pink lips were stretched obscenely around the red ball in her mouth. Said ball had a small hole right through the middle of it, to aid breathing and presumably insert any liquid into the slaves mouth through a tube if desired. Lisa had once drank a coke through a straw with it... difficult, but possible!
Drool ran down her chin in a steady stream. It always happened in this gag, and made her feel a little embarrassed. As it dripped onto her freckled chest, she pulled her hair back into a short ponytail, and then headed back to the bedroom to continue where she left off.
Lisa had a set of leather cuffs, a pair for the wrists and for the ankles. She buckled and locked these on too, but did not connect them to each other. She had read stories of self-bondage going wrong, and the horror of her private life being discovered, or even worse, filled her stomach with vomiting butterflies. She would be careful this time, this would be tricky enough as it was. Same went for the nipple clamps. Even though her arms would be free to remove them, she felt the extra sting of biting clamps might be a bit much.
Taking a deep breath, she took a condom off of the bed. It was from the biggest ones she could find, and Lisa was extremely glad she ordered them online so as not having to deal with the leers and winks of an... unprofessional shopkeeper at the pharmacists. Removing it from the package, she felt a familiar tingle in her pussy. Then taking the bottle of lube and the condom, she stood at the end of the bed.
The thick, wooden bedknob stood in front of her, taunting her with its girth. Ever since she had started exploring her body, she had wondered what it would feel like inside her. It was made from polished wood, with ridges and curves all down its length, topped with a slightly elongated knob rather than the classic wooden ball. It was probably 3 inches across at its widest point, and stood almost 3 feet tall from the floor. In fact, if Lisa managed to mount it as she planned, her feet would struggle to touch the floor. She had stacked some thick books below the corner of her bed for her to stand on, to avoid jumping in too deep, so to speak.
As the trailing drool dripped off her pert nipples and onto the floor, Lisa carefully rolled the condom down the wooden bedpost. She then lubed it up, and rubbed the remaining sticky gel into and around her pussy. Shuddering with excitement, she almost came right then, but decided to hold off her first orgasm of the day until she was skewered properly.
Lisa climbed up onto the stack of books, a small pile for each foot, and shuffled her cute behind over the intimidating pole. She moved her hand down past the small patch of soft, red pubic hair and spread her lips with her fingers. Lisa gasped as she squatted down gently onto the thick bedpost, and grunted as it slowly entered her sex. Wincing a little she pushed on, the drool from her gag running down her chin and belly as she stared down at her splayed pussy. The bedknob itself wasn't too bad, and she settled down over it, moaning softly.
Now for the next part, she thought to herself. She wiped her chin of drool absent mindedly, and lowered herself towards the widest part of the post. Grunting, she braced herself and pushed against the wood, feeling herself stretch around it. It was painful, but felt so good to be so full, and soon the worst was over. The rest of the post was pretty easy once she was past that challenge, and she could now slide up and down with relative ease.
Lisa closed her eyes as she fucked herself on her bedpost and rubbed her clit. She wished she had a big mirror in here to see it, see the humiliated slave girl skewered on a fat, wooden pole. She imagined someone finding her, the shock and disgust they would have, the shame she would feel. Maybe she should film it next time on her phone... Her cheeked flushed red as she continued to hump the unforgiving pole, she could feel the orgasm building.
Then it all became too much for her. Lisa felt the waves of delight wash over her as she came, her fingers moving furiously over her clit. She gasped under the gag and threw her head back as her hips twitched around the unmovable invader. Unfortunately for Lisa, while fucking the post she had not noticed the books slipping under her left foot. As she thrashed about, the top book finally slipped and her left leg kicked up in a panicked reponse. Eyes wide now, still dazed from the orgasm, she tried to right herself but knocked away the books on her right side too. As the surprised teen dropped down the length of the pole, she grunted in pain as the bedknob bumped into her cervix, triggering another orgasm.
Lisa tried to stop squirming around and stood on her tiptoes to avoid resting her weight on the post itself. Her hands struggled to find purchase on the slippery pole in an attempt to pull herself off it, but to no avail. She grunted with exertion as spittle frothed around the wide ball in her mouth.
"Oh god!" thought Lisa, "Oh I'm so full, and I don't know if I can get off it!"
Her legs were already starting to ache and her toes hurt. The dog tag jingled on her collar as she looked wildly around the room for something that could help. She couldn't stay like this until her parents got home in two days time, her life would be over! She regained a little composure, it didn't feel too painful at least. In fact, it felt really good. Releasing her grip around the pole, she got her balance and touched her clit gently. It only took a few seconds for her to come again, any discomfort forgotten for a few fleeting moments.
"Ohh it feels so good," thought Lisa, as she attempted to regain her balance, "but I really think I'm stuck."
Even the thought of being impaled here for real, helpless and humiliated, made her shiver. She looked down at her body, her little breasts covered in saliva, nipples standing straight out. She could see the bulge in her usually flat belly where the intruder filled her. Lisa couldn't resist rubbing another orgasm out as she stared at herself. Imagine if someone broke into the house to find this, they wouldn't really provide the help she needs... but would possibly give her the attention she wants.
Snapping out of her reverie, Lisa glanced over her shoulder at the bedside clock. Almost 4pm, she had been here just over 40 minutes. Every little movement was setting her body off, but she could not stay here forever. Straining and grunting, quite unladylike, she reached for her phone sitting on the desk. Her fingertips touched the edge, and she winced in a mixture of pleasure and pain as she leaned over and attempted to coax the phone closer.
