[Katrin1988]

About video: I've always been there for my friends, and when Jayda suddenly vanished from my best friends life, I consoled him as best I could, trying my hardest to get him to forget her. After all, he'd never see her again, especially since I had decided to make her my own personal plaything! She'd spent the past several months as my captive, bound and gagged as I slowly worked to remove all traces of her existence and cover my tracks. Now, on the eve of his wedding, my friend has called again. Seems he can't get Jayda out of his head. As I talk him down, Jayda lays across my lap, desperately trying to alert her ex to her plight, but with my hand clamped tightly over her face, her cries are swallowed up completely and only feeble impotent "mmmmppp" sounds can be heard! After I ended the call, I packed her mouth with cloth and sealed it shut with brutally tight wrappings of vet wrap before roughly running my hands all over her body, squeezing that magnificent ass and telling her of all the things I had in store for her! My friends bride may have something old and something new, but I definitely have someone borrowed and someone blue!

About video: If there's one thing Jayda knows how to do, it's struggle, so we give her every opportunity to do so in this scene! Beginning in a tight hogtie, her snug jeans clinging to every curve of her magnificent ass, she is first cleave gagged with a massive amount of cloth, then further silenced with a brutally tight cloth OTM gag that renders her very muffled indeed! Of course, she can end her torment with ease, providing she can work her way loose from the tie! Watching her squirm and twist as she struggles for knots that seem just out of reach is sexy as hell, and soon her diligence is rewarded as she slowly but surely manages to release the ropes one by one before removing the gags from her lovely face and triumphantly bolting from the room! Next time, she won't be so lucky!

[Katrin1988]

About video: It was a very special day for Jayda. After all, it isn't everyday when you receive a brand new set of lingerie! The pure, virginal white set was beyond sex, right down to the matching garters and stockings, and she couldn't imagine how it could look any better. But her friend did have some ideas for a few accessories that made it a bit more visually appealing, at lest, they did in HIS eyes! Starting with the fat red ball gag that kept her silent and drooling, and followed by the ropes that fused her squirming body to chair and nestled themselves up in her crotch, slipping up into her pussy, tightening with every move she made. Of course, the outfit could look beautiful with any number of additions, as he demonstrated by swapping her ball gag for a cock gag, taped tightly in her mouth so it would constantly tickle the back of her throat! And of course, if she preferred jewelry, the one of a kind nipple clamps fashioned from a skirt hanger, locked onto her tender buds and tied into the rest of her predicament, would SURELY turn heads. At least, they would if she were ever allowed out of her home again, but as she was about to learn, freedom was never going to be an option ever again!

About video: Ah, the youth of today. Take Jeanette Cerceau, for example. So spirited, so headstrong. It's a good thing she has the older generation to teach her some discipline. Now, instead of frittering away her evening at some bar or club, she'll be safe and sound at home. Of course, being unable to move or speak, ropes crushing your limbs and rubber plugging your mouth may seem like an extreme way to teach a girl a lesson, but someone has to instill some manners in this generation!

[Katrin1988]

About video: She'd been warned many times. The news was filled with reports of break ins plaguing her neighborhood, and her mother had pleaded with her to move to a safer town, but Jeanette was stubborn....and careless. She soon found out, however, that both traits carried a high price! When the man appeared behind her and clamped a hand over her mouth, she instantly knew that all the warnings she had received had in fact been very prescient! Now, she was tightly bound, anchored to her bed with what seemed like miles of rope and tape, ensuring there was no way she could escape. Her captor wasn't much for small talk, and he ensured she wouldn't be making any either by stuffing her mouth, yanking a pair of pantyhose over her head, and sealing the entire mass shut with circuit after circuit of sticky tape! As her mouth was fused shut and the pressure built, she was horrified when the tape began to wind itself around and around her eyes! Now unable to see, speak or escape, she was left to grunt and struggle on her bed while the assailant robbed her blind. She was left there for hours, and after what seemed like an entire day of fruitless struggling, she collapsed in exhaustion. She could only pray for a rescuer to arrive and release her! Finally, her prayers were answered! Her roommate returned home, but he had spent the evening celebrating with the boys, and could barely see straight, let alone notice her plight! Toddling off to bed, he left Jeanette tied and gagged as she grunted in fury! It was the beginning of what looked like a VERY long night!

[Katrin1988]

About video: The man was so mean! He pinned my elbows behind me and marched me into the room, one hand clamped over my mouth so I couldn't call for help! Then he made me strip out of my jeans and down to my panties! I had hoped he would stop there, but no such luck! I had to take off my shirt! Of all days not to have worn a bra! Then he sat me down on a chair and began to lash my body tightly to it! The ropes bit into my bare flesh, and he added an embarrassing chest harness to show off my boobs! Then he jammed a huge cloth into my mouth and tied a scarf around it to make sure I couldn't call for help! He left me then, but as I struggled in vain, I wondered if he'd be coming back, and what he might do when he did!

[Katrin1988]

About video: Jeanette has been busy working all day and is ready to just lie down and be done with it. After taking a moment to lie down on the couch, she notices that her roommates left her a present for her birthday, which she completely forgot about after today. When she opens the package, a puff of some mysterious gas flies into her face, and when the gas clears, she is dressed in a strange PVC maid outfit. She also finds some kind of computer chip lodged on her forehead. She attempts to remove it, when an alarm goes off, and several spools of tape scramble and begin to fly towards her. A strange voice introduces himself. He says that he is an alien from a distant planet. He says that this whole room is actually only a holodeck meant to simulate Jeanette’s apartment, and that the alarm went off because she was close to unveiling the trick. He has assumed a human form so she is not too frightened by his alien appearance. As he begins to explain, he begins to view her curiously, like how a zoologist watches animals. The alien is bent on collecting specimens on behalf of what essentially is an Alien Zoo. He takes out a remote and types several commands. Jeanette asks what he is doing, but finds her body moving on its own. She is XXXX to stand at attention, head held high. A feather duster appears in her mouth, secured by a large ball. Now silenced, he inputs some commands for Jeanette to begin cleaning this room. Although Jeanette continues to gag talk some angry remarks, her body moves on autopilot, dusting every surface. Finally, it is time for deep space travel. To ensure her safety, she is fitted with a pump gag that will be used to supply oxygen to Jeanette during the trip. Jeanette makes one final plea before being silenced, but she is magically hogtied and left to struggle helplessly before vanishing into the deepest regions of space, destined for a life of performance behind bars!

About video: A simple scene: Bound wrists, legs spreadeagled as far as her tight jeans will allow, mouth stuffed and sealed with tape, and some very energetic struggling! Jeanette made a bet that no matter how hard she thrashed, she could keep her bra hidden from sight. As you can imagine, she lost! Her penalty? Staying that way for the rest of the night!!

[Katrin1988]

About video: Jeanette was only too happy to help me out by modeling for my new web platform. She was also quite surprised to learn in was a bondage platform, and she was going to be the chief attraction! Welded to a chair in what seemed like miles of black tape, she was utterly fused to the furnishings, ensuring she'd always be available for a photo shoot whenever I needed it! Of course, developing a new platform is a LOT of work, and I need my silence, so I just had to pack her mouth full of old cloth before sealing it shut with even more tape! Now she'll always be at my beck and call!

[Katrin1988]

About video: Jeanette injured her leg and is in great pain. Unfortunately, being a young and uninsured millennial, she has to resort to rather unconventional doctors with rather questionable methods. At first, all seems well as he examines the injury. Maybe he spends a little too long running his hands over her leg, but Jeanette can't afford to argue, and lets the indignity pass. Her mind clears a bit when he outlines his steps to immobilize the leg, wrapping a tight white bandage around it. Jeanette has to admit it already feels better, and the painkiller the doctor gave her has left her feeling VERY relaxed indeed. So relaxed, in fact, that before she knows what has happened, she's been wrapped from shoulders all the way down her young, slim body! As her head clears, she is initially confused by the way her arms are folded tightly against her chest, her limbs fused together, even her feet pressed so tightly that she can do nothing but wiggle them underneath the bandages! When she protests, the doctor insists upon quiet for her treatment, and immediately crams a large sponge ball into her mouth, sealing it in with tape! First, circuit after circuit is passed between her teeth, then wrapped again and again until her mouth and lower face have vanished between the silencing black band! Now truly furious, she squirms and thrashes, but the bandages make an effective and inescapable cocoon! The doctor soon reappears, displeased at the movement still available to her enveloped feet. With his medical shears, he cuts off the bandage to reveal her socks, then cuts them away to reveal her wriggling, grasping toes! Utilizing a piece of twine, her toes are tied together and the girl left to "recuperate". The only question? How long will the doctor demand to oversee her treatment?

About video: Poor Jeanette! Taped up tightly in three different positions, all of which leave her unable to do anything more than struggle, whimper and grunt into her various gags! We made sure to place her into a very short shirt so she cannot possible help but provide plenty of up-skirt peeks at the crotch of her pantyhose, whether she likes it or not! From tape gags to hogties to knotted cleave gags to chair ties, even an unusual crossed legged tape box tie that keeps the crotch panel on her pantyhose on full display, this little beauty only exists for your pleasure! If she only knew how much you enjoyed her struggling!

[Katrin1988]

About video: I celebrated a milestone birthday a short time ago. What made it a milestone? Well, it was the gift I received! I'm still not sure which one of my friends brought the tightly bound and gagged Asian princess over, or whether she came willingly. Scratch that. Judging from the way she was fighting against her bonds, she MUST have been unhappy to be there! Not that it mattered, with the fat ball gag stifling her cries and the blindfold ensuring she not only could not identify me, but that she would have no idea what was about to happen to her! Her giant tits were certainly enticing, as was her gorgeous ass straining within her jeans with every movement, but I was drawn to her pretty little helpless feet, and soon found myself rubbing them and sucking them as the girl mewled in fear and disgust. Of course, that was just an appetizer for the main course I had planned for her. But first, I thought she could use a little stimulation, knowing that would not only humiliate the poor girl but make things a little easier when I finally broke in my present! So, with her jeans and panties pulled down, a vibrator tied to her sweet young pussy and turned on high, the girl was left to moan and writhe in bondage. Was it from embarrassment? Distress? Fear? I couldn't be sure, but that wet pussy sure seemed to indicate otherwise!

[Katrin1988]

About video: Katana had moved to her new home not long ago. She had seen her neighbor a few times. Not too much special about him, but he seemed friendly and he greeted her when passing her in the hallway, and so did she. One thing though that made her curiosity run into overdrive was the many different gorgeous girls who typically was some younger than he was visiting him. Katana knew she had to learn what made all these gorgeous girls visit there. One day she had a good feeling he’d be out and she could sneak in to snoop around. She entered the living room and was in for some surprise: a leather strap with a big rubber ball in the center of I, piles of ropes in all lengths and colors, a great amount of duct tape, pieces of torn clothing, and his computer, displaying countless pics of tied and gagged girls! She knew she should leave immediately, but couldn’t help but be overcome with a desire to see what such bondage felt like. She gagged herself and bound her legs tightly. Lost in the pleasant sensations of how the ropes worked, she did not hear her neighbor return. When his hand clamped over her mouth and yanked her from the chair, she knew she was in for a very difficult afternoon! Moving quickly, her tied her hands behind her, added even more rope to her legs, and bound her torso! Now fully secured, protesting and mewling into her gag, she could do nothing to prevent him from cutting holes in her top to expose her big tits! Despite her struggles, he easily placed her on the ground and hogtied the frantic girl, and for the finishing touch, tied a vibrator between her legs! When he switched it on, her eyes flew open and grew huge with shock at her violation! Still, she could not prevent her body from betraying her as she began to edge toward climax! She writhed and moan in embarrassment, shame and lust as the neighbor watched her cum again, and could do nothing to stop him from taking her phone! He explained that several of her lady friends would be receiving special text invitations form “her”, inviting them over, at which point they’d fall prey to the same tight bondage and torment! Katana moaned, but was it in sympathy for her friends, or was the vibrator working overtime?

About video: Katana and Dahlia's television is on the blink, so Dahlia asks their creepy neighbor to fix it. He fixes it, and fixes the two girls in the bargain! When Dahlia switches on the set, a swirling spiral begins to spin before her eyes, and despite her best efforts, she cannot look away from it! The longer she stares, the more convinced she becomes that true happiness lies only in becoming a bondage pet for her neighbor! Not only that, but she becomes convinced that Katana must join her as well! When Katana arrives, she finds a very different Dahlia waiting for her, and cannot understand why Dahlia wants her to watch the remote control for the television set, and how it waves and dips in Dahlia's hands. The more she watches, the deeper Katana falls under the spell, and soon Dahlia's suggestions of bondage under the hands of the neighbor seem like the only true path to fulfillment. Soon, both girls are dazed, compliant and clad only in their panties, handcuffed and awaiting their neighbors bidding. He'd VERY much like to watch the two girls make out, and immediately Dahlia and Katana begin to kiss and fondle each other, their lips dancing over each other's breasts, their tongues rolling slowly over the other's body, their lips pressing together in soft kisses that really get the neighbor's blood flowing! Unfortunately, he has to leave for the day, but he ball-gags the two helpless, mindless pets, instructing them to become intensely aroused in their bondage, then directs them to position themselves face down on the sofa, asses up and waiting for him to return! The girls comply, swaying their bottoms seductively, happily moaning into their gags, waiting for their new owner to return and give them some much wanted attention!

About video: The housing market may be booming, but it still favors the seller, so realtor Katana Thorne really wants to put this buyer into a space she has been trying to unload for ages! The deal seems to be in the bag, but the buyer expresses concerns about whether it will work for his business needs. Katana offers to do anything possible to help him figure out if it will be suitable, and thus she made her first mistake! As soon as her back was turned, his hand clamped over her mouth and a sweet smelling rag pressed against her face! As she gasped for air, she felt her brain fogging over and her world went dark! When the fog finally lifted, she found herself topless, bottomless, gagged and bound to a pole that had been erected in the room! Turns out the buyer has a very unusual business, which he explained as he slowly enveloped the mewling, squirming girl in a cocoon of bandage and tape until she could barely twitch! She wondered why he had left her tits exposed and her pussy free, but as he slid a vibrator in place, and wedged it into her sensitive sex, she immediately knew the answer! When the buyer switched it on, Katana went into overdrive as she tried her best to fight the growing stimulation and preserve her dignity and modesty, but the vibrator proved to much for the girl and she shook with the first of many bound orgasms, each one causing her to moan and groan into her gag! The buyer is definitely interested, but is he more interested in the space or the girl??

About video: When Katana agreed to house-sit for the headmistress of the magic academy, she thought it would be a simple job, loaded with perks! For instance, she would finally have the chance to explore the headmistress' collection of enchanted bondage gear! First, she tries out the magic harness gag, but can't quite figure out how it works. Giving up, she tosses it to the bed, only to have it spring back up and lodge itself into her mouth, the buckle pulling tightly before locking shut!! At first, she enjoys the feel of it and the way her speech is muted into muffled moans. However, when she finds it CAN'T be removed, she begins to panic, mewling in fright and shock! She tries to call her friends for advice, but cannot make herself understood! Finally, in frustration, embarrassment, and exhaustion, she lays down for some rest, the gag still fused to her face. While she rests, a magic harness gag slithers its way up her body and before she knows it, she is tightly bound in just her bra and panties, the crotch strap digging painfully into her sweet young pussy! As she struggles, a ghost appears! Seems the bondage gear is haunted by a spirit of a sex fiend, and he has cursed the objects so that the wearers will fall prey to never-ending lust! Her passion growing, Katana begins to beg her unseen captor to jerk off, giving him instruction about just how and when to come! But when the moment of fruition is at hand, the poor girl is denied and is whisked away to the netherworld, never to be seen again!!

About video: Poor Katana! She'd grown far to comfortable flouncing around in her short skirts with no panties. She was definitely bound to attract attention....literally! Caught in her own home by a man who had watched her from afar on the city streets, the busty young thing was now bound to a chair, her ankles affixed to the chair legs, leaving her spread wide open for the perv to peek up her skirt at her bare pussy! The fat ball gag in her mouth kept her pleas for help to a minimum, not that the stranger would have paid any attention to her gurgling whimpers, fixated as he was on that sexy pussy. When he left her alone for a moment, Katana seized her chance, struggling to untie herself from the chair before he returned. In the nick of time, she managed to undo the ropes holding her in place, and rushed to her phone to call for help. That was her mistake! Instead of making a break for it, her phone call allowed her to be caught again, stripped naked as the day she was born, and tied in the doorway to her bedroom, her hands pulled high over her head, a handkerchief cleaving her sexy mouth, and her gyrations definitely enticing her captor! What will happen to the poor girl?

About video: Head Cheerleader Minx is facing one of the most important weekends of her life. Her football captain boyfriend is going to be quarterbacking the big game, and she's leading the cheer squad to cheer him on! At least, that's what she thought would be happening. Instead, one of the city's big bookies has decided to hedge his bets a bit by convincing the QB to throw the game, and to ensure he goes along with the plan, MinxGrrl is being held as collateral until the game is over! Bound to a pole in her cheer uniform, her mouth sealed shut with a microfoam plaster, she strugglers in fear as she seeks a way, any way at all, to escape from her bonds! Her tormentor enters and wraps tight medical bandage around her already silenced mouth, relishing her frightened murmurs. To humiliate her, he ties a tight crotch rope around her waist and snugs it deeply into her pussy, grinding against her as he does. She groans in disgust and anguish as he leers at her, raising her skirt to expose her panties and show off the way the rope is buried into her pussy. When she won't cease her struggling, he spanks her ass and leaves her to await the outcome of the game. One thing is certain, no matter which team scores, she's going to be a big loser!
