Amy suddenly farted – or at least, it sounded like it. And it also sounded really wet.

She gulped, sheepishly looking around to see if anyone noticed. Luckily, the lobby of her downtown Los Angeles apartment building was empty save for the front desk clerk, who was far enough away from her now.

It was just past 10pm on a Friday night. Amy hurriedly walked into a corridor where the elevators were located, carrying two paper bags full of groceries.

Another wet, squishy sound emanated from Amy’s ass. She blushed, glancing around nervously to make sure no one was approaching.

I really need to get home quick, she thought. This thing is making a mess in my underwear…

All of a sudden, she felt a jolt of pain course through her rectum.

Amy gasped. Oh, no… I didn’t expect that so soon!

Her curvy frame trembled from top to bottom as the nerve endings in her anus started to tingle – with both pain and pleasure.

The elevator was still a few floors away. Amy was in a ton of discomfort, struggling to hold onto her groceries. She cradled the bags close to her body, feeling like they were about to drop. Her body shuddered as she felt a huge amount of pressure in her rectum. She felt like she needed to use the restroom – badly – but that wasn’t quite the situation she was dealing with here.

Finally, the elevator arrived, doors opening. It was empty. Amy quickly walked inside, struggling to hold down the pressure in her quivering asshole. She pressed the button for floor 6.

The discomfort was now too much to bear. Immediately after the elevator doors closed, Amy dropped her groceries and hunched over, clenching the bottom of her flared yellow dress with both hands. Her long, silky blonde hair fell across her face as she moaned in agony.

Damnit, she thought. Why did she turn it on so soon?

Amy pulled her dress up, above her waist, and looked down at herself. The circular base of a black butt plug was visible through her red panties, tucked away in her ass. Her underwear was partially soaked with a thick, sticky, clear-looking fluid – it was clearly a lubricant of some kind. The lube had been emanating from her squeaky asshole, making the so-called “farting” noises.

This wasn’t any ordinary butt plug, however. The plug was remote-controlled and inflatable, with the ability to expand to double its normal size upon the press of a button. At normal size, the plug was more than manageable – Amy had held it in comfortably for over an hour and a half. However, at maximum size, it was a handful to deal with.

The problem, of course, is that Amy didn’t have the remote control. It was in the hands of someone else.

Amy wasn’t sure if the plug had been inflated to max, but it sure felt like it. She placed her right hand against the wall of the elevator, breathing deeply as beads of sweat started to form across her forehead.

Someone’s being naughty, thought Amy. And I don’t like it…

Amy exhaled deeply as she felt the massive anal plug pushing against her rectal walls. Some more lubricant oozed out of her anus, dripping onto the base of the toy. More farting sounds.

“Oh, God,” gasped Amy as she continued leaning against the elevator wall.

Amy’s plump breasts pressed against the elevator wall as her buttocks started quivering uncontrollably. Her asshole contracted around the base of the plug as more lube dribbled onto her panties underneath.

Finally, the elevator stopped at floor 6. Amy heaved a sigh of relief and bent over to pick up the intact grocery bags.

She grimaced as the gigantic toy pressed against her insides with every movement. She needed to move delicately. Very delicately.

Thankfully, her apartment was only a few doors away. She stopped at room 607 and rang the doorbell. Her arms were shaking as she again struggled to hold onto the grocery bags, while simultaneously clenching her buttocks around the thick sex toy that was deep in her ass.

The door was opened a few moments later by a young, 20-something woman. She was a redhead with glasses. What a combination.

Amy glanced at the pretty woman in front of her, marveling at her appearance, as she always did. It was her roommate Tracy.

Tracy was a tall, stunning 27-year-old with dark brown eyes and medium-length red hair. Her hair was a little ruffled, but it still didn’t detract from her sexy appearance. She was also a couple inches taller than Amy, although not quite as busty. Like Amy, Tracy was incredibly beautiful. Unlike Amy, she was originally from Europe, having moved to the United States as a young child.

She’s always so revealing, reflected Amy as she observed the skimpy clothes her roommate was wearing. Tracy had on nothing but a white t-shirt and tight green short-shorts. Her firm tits were clearly noticeable through the tight-fitting shirt.

Amy’s eyes were briefly drawn to a tiny, glistening silver dot above Tracy’s upper right lip. Turns out she had a lip piercing too.

“Hi, sexy,” said Tracy, smiling mischievously. “How was grocery shopping?”

“It– it was great, Tracy,” stuttered Amy, glaring at her roommate uncomfortably. She gingerly walked into the apartment as Tracy closed the door behind her.

Tracy was a manager at a local electronics retail store, having worked her way up to the position after a couple of years. She had hired Amy as a sales representative just over a year ago.

Strangely enough, despite Tracy being Amy’s boss, they became really good friends and started hanging out outside of work. However, Amy – who was straight at the time – was initially unaware that Tracy was a lesbian.

Tracy had fallen for Amy the moment she set eyes upon her, when Amy came to interview for an open position. Part of the reason why Tracy gave her the job was because she wanted to seduce her. Over time, she managed to befriend Amy and ultimately convince her to experiment with lesbian sex.

They first made love about six months ago, and Amy was hooked – they had been dating ever since. Amy was still a bit ashamed about it, as she hadn’t yet come out to her friends or family. Nonetheless, their relationship grew so strong that once there was a vacancy in Tracy’s two-bedroom apartment, Amy decided to move in with her.

Tracy checked out Amy’s gorgeous body as she strolled into the apartment. Everything about Amy’s appearance was such a turn on for her – the long, silky blonde hair, the bright green eyes, the slim yet curvaceous body. But the biggest turn on was how Amy was just a sweet, innocent girl at heart. Tracy felt like the luckiest lesbian in the world to have a girlfriend like Amy.

Amy slowly walked into the small kitchen to the right, setting the groceries down on the counter. She turned around to face her roommate. “Tracy, you turned it on too soon!” she exclaimed. “I wasn’t back yet!”

Tracy giggled and walked over to Amy. “Well, that was the point, dear,” she said. “I can turn it on whenever I want – since you’re my slave today.”

“Tracy, please turn it off,” begged Amy. She was down on all fours now, grimacing as the thick toy filled her tight rectum. “It’s so… uncomfortable…”

“Well, if you want me to turn it off, darling, you’re going to have to kiss me first.”

Amy looked up at Tracy and groaned. “I can barely even stand up right now! Can I kiss you afterwards?”

“Do it, slave,” said Tracy more sternly this time. Her body language suddenly changed from easygoing to dominating. “And remember your manners. You need to refer to me as your mistress at all times.”

“Sorry, Tracy, um… mistress, I – I’m not used to this.”

Today was the first day Amy started engaging in BDSM role play with Tracy. Up until now, they had led a relatively normal, albeit passionate, sex life. However, after much persisting from her aggressive lover, Amy had reluctantly agreed to engage in bondage play. Amy loved Tracy, and she didn’t want to disappoint her in the bedroom.

Amy sighed and slowly got up, struggling to stay upright as she brought herself close to Tracy. They stared at each other intently before their lips touched.

They started off slowly, brushing their lips softly together as they started warming up to each other. Tracy planted soft, supple kisses on Amy’s lips, savoring the closeness of Amy’s mouth, and enjoying the smell of her hot breath.

Soon Tracy started running her hands all over Amy’s tense body as they continued making out. Her right hand found Amy’s left breast and began kneading it through the dress. She could feel that it was starting to firm up.

Amy was able to briefly take her mind off the discomfort in her ass while she made out with Tracy; she loved making out with Tracy, bondage play or not.

Their kissing started to become more sensual and intimate. Tracy started using her tongue, lapping it against Amy’s as their mouths filled each other. They were fully engaged now, lips locked intensely, lathering their moist tongues against each other. Gooey strands of saliva formed between them whenever their lips separated. Each kiss became a mouthful of sensual intimacy.

“Mmmhmm,” breathed Amy intensely as she savored the smell and taste of Tracy’s saliva.

Once again, the sound of a seemingly wet, dirty fart could be heard emanating from Amy’s ass as more lube was expelled.

“Ohh, baby, you’re a dirty girl,” said Tracy, spanking Amy’s ass. Several drops of lube that had escaped Amy’s butthole started dripping down her thigh and falling onto the floor.

Amy’s mind wandered back to the thick toy in her anus. Her legs started trembling again.

“Please, please can you turn it off now?” begged Amy.

Tracy shook her head. “You’ve been forgetting lately, Amy. What’s the magic word?”

“Can you turn it off… please… mistress?”

Tracy smiled and squeezed Amy’s breasts, admiring her current state of discomfort. “You look so sexy, struggling from the pressure of that toy. It’s just what you deserve for taking your sweet time getting here.”

“I’m sorry, my mistress,” apologized Amy, desperate to ease the tension in her ass.

“Apologies accepted, my slave. Now let’s first take off this nice little dress of yours.”

Amy obliged and pulled the dress over her head, quickly tossing it aside. Underneath, she was wearing a red lace bra to go along with her matching panties. The silky bra cupped her firm, plump breasts nicely, barely covering her nipples.

“Your boobs are perfect, slave,” exclaimed Tracy, cupping Amy’s large tits with her hands. “I can’t wait to take this silly bra off, but first things first…”

Tracy walked over to the dining table across from the kitchen, where there was some BDSM-related paraphernalia strewn about. She grabbed two items: a red ball gag with a black leather harness, and a black leather bondage collar with a chain leash.

“You’ve been a bad girl, complaining too much,” chastised Tracy. “Bitching about the very butt plug that you agreed to stick up your ass in the first place! You were so eager and lustful earlier today when you allowed me to stuff your ass with it. And now you don’t want it anymore! Typical flip-flopping slut. Now you need to wear these two things for me – and then I’ll happily adjust the plug for you. First get down on your knees.”

“Honey, I agreed to stick it up my ass because you said you would be reasonable!” pleaded Amy. “You said you would only inflate it if we were at home together, having sex! You’re abusing your power!”

“Well, sometimes a mistress will have to go back on her word if her slave has been a bad girl.”

“How was I a bad girl?”

Tracy smiled naughtily and caressed Amy’s cheek with her fingers. “You said you would only take half an hour after work for grocery shopping. You took almost an hour.”

“It was crowded, I had no control over that…” Amy’s voice trailed off as she slowly gave up arguing. She reluctantly obeyed, kneeling down in front of Tracy with her mouth wide open.

Amy was about to realize that Tracy’s BDSM fetish sometimes went a little too far. Looks like she means business today…

Tracy stuffed the ball gag into Amy’s mouth and wrapped the harness around her head, securing it tightly. She then wrapped the dog collar around Amy’s neck. It was attached to a chain leash which Tracy held on to. There were additional hooks on the collar for attaching more chains, if necessary.

“You’re my little pet now, Amy,” she said. “Whenever I tie this collar around your neck, you become my little bitch. Do you understand?”

Amy nodded obediently, a somber look in her eyes. This brings you satisfaction? she wondered.

“Now come crawl with me to the bedroom, like the little bitch that you are,” ordered Tracy. “Don’t you dare get up until I tell you to!”

Jeez, she’s being a little testy today. What have I gotten myself into…

Amy was generally the more reasonable and level-headed of the two, while Tracy had always been the more daring and aggressive one in the relationship. So, it wasn’t surprising that things were ultimately turning out this way.

Amy got on all fours and crawled across the living room with Tracy, who continuously tugged on her with the leash. Tracy led her into a hallway just right of the kitchen. They entered the first door on the left, which was Tracy’s room.

The room was simple and neat. There was a bed in the center, with a grey metallic bed frame, and adorned with a small wooden bedside table. The room was desolate otherwise, save for a sliding closet and a large window.

“Get on the bed, honey,” ordered Tracy. She removed a small remote control from her pocket.

Within seconds Amy was laying back against the blue bedsheet, resting her head against a pillow. Her entire body was shaking. The discomfort she felt was indescribable. Her rectum was rejecting the toy, pushing hard against it, but to no avail. It was impossible to push out.

“Now, you get your wish,” said Tracy, smiling mischievously as she pressed a button on the remote control.

Amy let out a sigh of relief through the ball gag as she felt the electronic toy slowly shrink inside her rectum. The butt plug deflated down to its original size, relaxing the monstrous pressure it had exerted on Amy’s rectal walls.

Tracy opened the sliding closet and grabbed a pair of leather wrist cuffs. “Stay where you are, slut,” she said, crawling onto the bed. “Before I forget, I should wear you these.”

Tracy forcefully grabbed Amy’s wrists and cuffed them, attaching them together with a chain in between. It was basically an elaborate set of handcuffs.

Amy wasn’t happy about having her hands locked up, but she didn’t want to defy her dominant girlfriend and get some other “punishment.” She rested her cuffed hands on the pillow above her head.

Their bodies were pressed firmly against each other, and Tracy grinded slowly back and forth on top of her submissive girlfriend. She started planting soft kisses down Amy’s neck and in the crease between Amy’s breasts.

Amy whimpered as she felt the cool moistness of Tracy’s lips touching seemingly every part of her skin.

“Let’s get this off,” said Tracy, unbuttoning Amy’s bra from the front.

The bra came off, and Tracy wasted no time playing with Amy’s large, plump breasts. They jiggled up and down as she eagerly fondled them.

“I love the way your boobs jiggle when I touch them,” said Tracy. Amy couldn’t help but giggle through the ball gag as Tracy started sucking on her right nipple, lathering it in saliva.

Tracy cradled Amy’s right nipple with her mouth. Spit dribbled out from her mouth and coated Amy’s nipple. She moved over to Amy’s left nipple and sucked voraciously. Slowly, deliberately, she worked her way from Amy’s tits down to her belly.

Amy trembled as Tracy left a trail of saliva down her abdomen. She dipped her tongue into Amy’s bellybutton, lathering it in drool, before sliding her tongue down to the top of Amy’s underwear.

Not wasting any time, Tracy slipped off Amy’s moist panties. Her nipples started becoming erect as she stared in awe at Amy’s unshaven pussy.

Ah, the female genitalia. This was Tracy’s most irresistible guilty pleasure – a woman’s private parts.

“Let’s see what we have here,” said Tracy curiously. She spread apart Amy’s thick pussy lips to reveal the juicy pink flesh underneath, marveling at every aspect of Amy’s pussy. Every part – from Amy’s erect clitoris, to her urethral opening, to her vagina – was absolutely perfect. A thick, milky-looking fluid was starting to seep out of Amy’s vaginal entrance, which was throbbing slightly.

Looking further downwards, Tracy enjoyed the sight of Amy’s tight, wet butthole wrapped around the base of the butt plug. The tight, brown folds of Amy’s anus were hugging up against the circular plug, preventing its solid base from being sucked in.

“I think we’ll leave this toy in for a little while longer,” said Tracy. “I hope you don’t mind.” She leaned forward and brushed her nose up against Amy’s hairy mound, and started licking her clitoral hood.

Amy groaned as she felt Tracy’s wet tongue lapping against her clit.

Tracy used her fingers to keep Amy’s pussy lips spread and dipped her tongue inside, letting it circle around the urethral opening, just above Amy’s vagina. She then began tongue-fucking Amy’s pussy, repeatedly thrusting her tongue in and out of the vaginal opening.

Amy grabbed onto the bed railing above her with her restrained hands. Her mouth had been held open for so long that some drool was starting to dribble out from the right side of her mouth. It streamed down her cheek and neck. Her muffled groans pierced the air as she felt Tracy’s moist tongue sliding into her inviting vagina.

Finally, the delicate fold of skin covering Amy’s clit retracted. Tracy lapped at it with her tongue, causing Amy to start grinding her buttocks into the bed. Amy’s vaginal discharges began streaming steadily down past her perineum and onto the base of the butt plug below. They tasted mostly sweet and salty, much to Tracy’s delight.

Tracy briefly moved from Amy’s clit and down to her perineum, delicately licking the region in between her pussy and asshole, slurping up the cum which she found so delicious.

Amy groaned in ecstasy as she shook her wrist cuffs. She squirmed as Tracy’s tongue continued to tickle her delicate pussy.

“Mmmm, I love how your asshole is so tightly wrapped around this butt plug, baby,” remarked Tracy. “Your dirty little butthole must really love that toy.” She spanked Amy’s left thigh mischievously.

Tracy focused back on Amy’s moist pussy, noticing the ever-increasing stream of white fluid dribbling out of her vagina. She dug her tongue in and continued eating Amy out vigorously.

Tracy formed an O-shape with her tongue and wrapped it around Amy’s bulging clitoris, sucking on it for the next few moments. Finally, Amy’s legs started to tremble, her hips bucking up under the pressure of the ensuing orgasm. She let out a huge groan that was drowned out by the ball gag filling her mouth.

Amy’s eyes rolled back as she started to come. She wriggled in ecstasy as Tracy’s tongue glided across her delicate, moist vaginal walls. Her pussy throbbed with the ensuing orgasm, and a final stream of fluids emanated from her vagina, directly onto Tracy’s eager tongue.

“You taste so good, darling,” said Tracy. Her entire mouth and chin were now enveloped in Amy’s pussy juice.

Amy’s body relaxed as she began coming down from the massive orgasm. Tracy crawled back up onto her and pressed their bodies together. Even though Tracy still had her shirt on, Amy loved the robust feeling of their breasts pushing against each other. It was so sensual.

Tracy’s lips were covered in a sloppy mixture of her own saliva and Amy’s bodily fluids. She gently pulled out the ball gag and rested it on Amy’s chin. Before Amy had a chance to speak, however, Tracy had already buried her tongue in Amy’s mouth. They kissed eagerly for a couple of minutes, giving Amy a chance to taste herself. She willingly slurped up the sloppy wetness coating Tracy’s lips and surrounding skin.

“Now I want you to turn around and get on all fours,” said Tracy.

Amy slowly obliged and positioned herself doggy-style. Her tousled hair fell over her face as she buried her head into the pillow.

“Put your ass a little higher in the air – good girl.”

Tracy crawled up in front of Amy’s thighs, which were spread wide apart, and placed her hands on Amy’s buttocks. She planted a kiss on Amy’s right butt-cheek and gently caressed the area around Amy’s tender asshole.

“I think you’ve had enough of this thing, haven’t you?” Tracy wrapped her fingers around the thick base of the toy, wiggling it slightly.

“Yes, mistress, may you please remove it now?” pleaded Amy.

Tracy playfully spanked Amy’s right butt-cheek. “Yes, I may, my dear slut. You can push it out. I’ll give you a hand.”

Amy began pushing the toy out – a much easier task now. The main shaft of the plug slowly began making its way out from Amy’s anus. Tracy held on to the base of the toy so that it wouldn’t fall out.

The sight of the thick black plug sliding out of Amy’s tight butthole was making Tracy incredibly horny.

Before inserting it, Tracy had lathered the rubbery plug in a type of water-based lubricant, which was now being excreted in bunches along with the toy. Tracy loved how Amy’s asshole briefly expanded as the widest part of the plug passed through.

Finally, Amy expelled the last part of the plug. A distinct “plop” sound could be heard as the toy popped out. Amy’s moist asshole contracted rapidly after the plug came out.

Tracy held the sticky, black toy in her hand and examined it for a moment. There didn’t appear to be anything other than lube on the plug. I guess Amy’s rectum is relatively, um, clean.

After setting aside the toy, Tracy squeezed Amy’s butt-cheeks lovingly and then leaned forward, examining Amy’s contracted asshole.

It was simply mesmerizing. The ivory-brown folds of Amy’s dark, moist anus had contracted, no longer forced open by any plug. A few hairs dotted the moist skin around it. So pretty.

Amy squealed in surprise as Tracy buried her tongue into Amy’s trembling asshole.

“Ahhh, what are you doing?” exclaimed Amy. Tracy had never given her a rimjob before; it was something that had always made Amy feel uncomfortable, even though she was fine with sticking toys up there.

Tracy spanked Amy’s left butt-cheek. “Don’t make me put that ball gag back in your mouth, slave,” she warned.

“But mistress… my ass is so dirty!”

Tracy let out an exasperated sigh, and she leaned forward to reach for the ball gag that was hanging around Amy’s neck. She mercilessly stuffed it back into Amy’s mouth, ignoring her grunts and wails.

Continuing where she left off, Tracy dipped her tongue back into Amy’s tight asshole, letting her saliva drip onto it. She repeatedly tried to crack it open with the tip of her tongue.

The taste was somewhat dirty and unpleasant – almost bitter and musky. Certainly not as pleasant as Amy’s pussy. Even though Amy’s butthole appeared to be devoid of waste matter, Tracy could still apparently taste something that perhaps was not so hygienic. She didn’t mind, however, as long as she wasn’t literally eating shit.

“Mmmhmmm,” slurped Tracy, lapping her tongue hard against the brown folds of Amy’s moist anus. She could feel Amy breathing deeply now as another orgasm approached.

Amy’s body squirmed as she held onto the bed railing with her bound hands. She was relishing the new feeling of being licked down there.

I had no idea analingus would be this good! I just hope she doesn’t try to kiss me afterwards…

Tracy continued lapping her tongue against Amy’s butthole, savoring the filthy odor and taste. Amy’s groans grew louder as she held on tightly to the pillow. A steady new dribble of fluid streamed out from her vagina.

Tracy started rubbing Amy’s clit with her fingers as she continued with the analingus. It only took a few more moments for Amy’s body to tremble under the pressure and give way to another orgasm. Amy climaxed in beautiful fashion as her pussy trembled from another quick orgasmic release.

Tracy savored Amy’s asshole for a few more moments after she climaxed, and finally let go.

“Now you’re going to have to kiss me,” said Tracy with a naughty smile. She caressed Amy’s thigh and crawled up close to her, as Amy’s body shuddered from the aftermath of the monstrous orgasm.

Amy shook her head as if to indicate no; she was paranoid about the hygiene of her ass. However, Tracy wasn’t in the mood to be disobeyed. She ripped the ball gag out from Amy’s mouth as Amy squealed in fear. Amy tried to pull herself away but Tracy was too fast, engulfing Amy’s lips with her mouth.

“Ewww, gross,” groaned Amy as she continued trying to struggle. But Tracy was just too forceful. She forced her dirty lips onto Amy’s as their mouths locked in a tight embrace.

“Deal with it, baby,” said Tracy. “It’s your own ass!”

After a few moments of forceful kissing, Tracy finally let go of Amy and got up off the bed, somewhat annoyed. She looked at Amy and crossed her arms. “You’re really misbehaving today, dear,” she said. “I’m a bit disappointed in you. I’m going to have to restraint you even more for this next part.”

“Oh please no, I’m sorry, mistress,” pleaded Amy apologetically. I don’t want to be restrained any further…

“Too late. You disobeyed me first by not being willing to receive analingus, and then again by not being willing to taste your own ass. You know the rules of our play – we discussed it earlier today just before we began.”

Amy gulped as Tracy briefly left the room. She was having second thoughts about the whole BDSM play thing, and wanted to protest – but hesitated.

I love Tracy so much, thought Amy. She’s the best girlfriend in the world – I don’t want to disappoint her, no matter how far she’s taking this…

Let’s just tough it out and make her happy.

A few moments later, Tracy returned with another elaborate looking BDSM toy – this time, it was a steel bondage bar with two attached leather cuffs, each at one end. There were additional hooks for attaching more cuffs if needed. The bar appeared to be around two feet in length. It was designed to spread a person’s legs apart while being cuffed to a person’s hands and feet.

“Now, my dear slut, please get on your back and spread your legs,” ordered Tracy. “I’m going to restraint you like the little bitch that you are.”

“Yes, mistress.”

Amy complied as Tracy got onto the bed. Tracy then lifted Amy’s legs into the air, keeping them spread wide, knees bent. Amy’s moist vulva glistened as she started to become wet again.

Despite the uncertainty of what was next, Amy couldn’t help but continue to be aroused. It seemed like much of Tracy’s kinky tendencies lied within this BDSM fetish of hers. After all the discomfort Amy had been through already, she was still a little curious to unearth more of Tracy’s kinkiness. Where did she get all of this experience? And how many women has she actually done this with?

Tracy set the bar on top of Amy’s legs, just above her feet, and she tied the bottom two cuffs around Amy’s ankles.

“Give me your hands,” said Tracy. Amy obliged, and soon her wrists were cuffed to separate ends of the bar. She was now locked into the missionary position, with her hands bound to each side of her legs, and her pussy readily accessible.

Tracy opened a drawer in the bedside table. She grabbed a small, thin metal rod that was perhaps only a few millimeters in width, and about three or four inches in length.

“What’s that, mistress Tracy?” asked Amy. She had never seen such a small toy before.

Tracy looked at Amy and smiled. She caressed Amy’s cheek and bent down to her face, letting their lips lock intimately for a few moments. Then, to Amy’s surprise, Tracy abruptly plugged the ball gag back into her mouth.

Amy tried to say something through the gag, but Tracy gently slapped her left cheek. She leaned in to kiss Amy’s neck a few times and then crawled back in between Amy’s legs.

“Amy, my dear slave,” purred Tracy, slowly caressing Amy’s right thigh. “I’m going to introduce you to something new. This little item here is what’s known as a urethral sound.”

Amy’s eyes bulged wide as her body trembled anxiously. Urethral? What…?

Tracy held up the metallic rod for Amy to see clearly. “I know it has a weird name, but remember – this urethral sound is nothing more than a metal rod. It’s basically like a ‘dildo’ for your urethra!”

Amy looked on nervously with wide eyes. Tracy rubbed some of the freshly emanated fluid from Amy’s vagina across the tiny urethral opening just above it.

But isn’t the urethra really delicate? Amy wondered. How the hell…do you stick something in there??

“Your urethra looks amazing,” marveled Tracy, in awe at the beauty of Amy’s tiny piss hole. It was so pretty – a juicy, inviting little piece of pink flesh that sat right there in the middle of Amy’s pussy. Amy breathed deeply as Tracy continued rubbing on it. Finally, she slid the urethral sound inside.

Amy started grimacing as she felt the metallic sound filling up her tiny urethra. Initially, there was some pain as her slim urethral canal was stretched to its limit with the thickness of the sound.

“Ohhmmggmm,” Amy groaned, as Tracy slowly inserted the sound deeper and deeper.

Tracy spanked Amy’s right thigh. “Don’t struggle, my slave,” Tracy scolded. “This is not going to hurt. It will only be pure pleasure. Do you understand?”

Amy nodded in obedience.

“Good.” Tracy continued sliding the sound in further, until it was almost all the way in.

Amy was overcome with an incredible new sensation. She had never imagined that you could stimulate your urethra, of all things! Initially it felt uncomfortable, and slightly painful; but eventually she started enjoying the feeling of the cool metal rod filling up her warm, moist pee hole.

However, Amy’s bladder was partially full and she needed to pee soon. The urethral sound was almost reaching her bladder, and she suddenly felt like it was going to explode.

After a few moments the sound did indeed reach the edge of Amy’s bladder, and Tracy gently nudged it a bit further so that it pushed past the sphincter.

There was a bit of pain upon hitting the sphincter, but once the sound had entered Amy’s bladder, the pain subsided somewhat. The sensation of the tiny metal rod holding her sphincter open was new…and pleasurable, in a twisted sort of way.

Amy felt like her bladder was about to burst due to the filling sensation that the sound provided.

“Ah, my darling, my beautiful slut,” said Tracy, watching Amy’s trembling, restrained body writhing ever so slightly. She loved the sight of Amy’s vulnerable, submissive body, unable to move with such a sadistic restraint keeping her locked into one position.

“I love you so much, Amy. You are a worthy sex slave – I’ve managed to get this whole thing inside of you. It’s hitting your bladder now, isn’t it?”

Amy nodded, grimacing slightly as the rod pressured her bladder.

“Your urethra is so gorgeous,” continued Tracy. “That soft, sweet, cute little hole is all filled up. Your pussy is literally leaking now, darling! Now, it’s time for you to come!”

Tracy gently started thrusting the sound in and out, fucking Amy’s urethra with it. She simultaneously rubbed Amy’s throbbing clitoris with her other hand, while Amy squirmed.

The sound gently hit Amy’s bladder over and over, and she couldn’t help but release the pressure every time her sphincter was pushed open. A small amount of urine started to gush out.

Amy started grinding her buttocks into the bedsheet below. She breathed deeply through her nose, heaving her breasts in the air, as Tracy continued fucking her urethra sadistically.

Ohh, God, I’ve never felt like this before…

Amy wriggled, the cruel restraint limiting her movements. The BDSM roleplay had gotten to a point she had never previously envisioned when she agreed to participate. Nonetheless, she was starting to like it. Playing the role of a submissive sex slave was growing on her, the same way lesbianism had grown on her when she initially got to know Tracy.

Tracy’s got the craziest BDSM fetish, thought Amy, as she felt the cool metal sliding across her urethral walls, the thickness of the metal filling and stretching her delicate urethra. Her vaginal opening was covered in a messy, whitish mixture of her own bodily fluids, which continued to ooze out.

Tracy started thrusting the sound faster, sensing Amy’s oncoming orgasm. Finally, Amy’s buttocks and thighs tightened up as she moaned deeply. Her pussy throbbed vigorously as a small amount of clear fluid squirted out.

“Oooh, nice!” said Tracy as she slowly pulled out the urethral sound. “You squirted a bit there.” As soon as the sound was removed, a steady stream of piss emanated from Amy’s urethra and splashed onto the bedsheet below. Amy’s body trembled as she simultaneously climaxed and emptied her bladder in front of Tracy.

“Wow, looks like someone had a little accident here! Naughty girl. You’re so fucking dirty.”

Amy shuddered as the waves of orgasm started to dissipate. She shook at her restraint and mumbled through the ball gag as Tracy set the urethral sound aside. Tracy crawled up to Amy’s face and gently removed the ball gag once again.

“Oh, my God, that was amazing!” exclaimed Amy, gasping, eyes wide with delight. The sensations she just experienced made everything leading up to it worth the trouble.

“I could tell,” responded Tracy with a smile. “You’re such a naughty girl. Such a naughty slave. The naughtiest ones deserve the best!” She brushed her left hand through Amy’s messed up hair and bent forward for a kiss. Their lips wrapped around each other voraciously, each woman suddenly overcome with extreme horniness.

“You’re the best mistress,” said Amy, in between kisses. “I want to continue being your slave whenever we get an opportunity. Don’t ever go easy on me. Teach me.”

Tracy dipped her tongue into Amy’s mouth, and Amy sucked on it willingly. Tracy slowly caressed Amy’s body as her saliva dripped into Amy’s gaping mouth.

“Mmm, mmhmm,” Amy slurped as her lips soaked up the spit from Tracy’s tongue.

Suddenly, Tracy pushed Amy gently back against the bed. “Well, darling, so far you’ve been having all the fun. It’s time for me to get a little action.”

Amy smiled. “Of course, mistress. Anything to please you.”

Tracy turned around and starting unlocking Amy’s wrist and ankle cuffs. Once they were undone, she tossed the bondage bar aside. However, she left Amy’s unrestrained cuffs on. Amy relaxed her body, with her arms and legs now free to move around.

“Thank you, mistress,” said Amy.

“You’re welcome. You’ve been a good girl so far, so I’ll give you – and me – a little treat.”

Tracy started undressing. She removed her shirt to reveal a black lace bra underneath, along with a glistening emerald navel ring. It was obvious that Tracy was a fan of bodily piercings. She also had a large color tattoo of a rose on her left shoulder.

Tracy untied her bra from behind and let it fall off. Amy enjoyed the view of her adorable mistress’s body. Tracy’s breasts were not quite as large as Amy’s, but they were still a good size. Her nipples were firm and erect.

Next, Tracy unzipped her shorts and slipped them off to reveal a pair of matching black panties. She smiled mischievously at Amy.

Amy giggled. “You wanna take off your nerdy glasses too?”

Tracy laughed and took her glasses off. Amy thought the glasses were a cute and sexy accessory, but she adored Tracy’s pretty face without them on.

Tracy slowly peeled off her panties as Amy got a glimpse of her lover’s shaven pussy. Then she spread Amy’s legs apart in a missionary position. She rested in between Amy’s legs, letting her pussy press against Amy’s.

Amy wrapped her legs around Tracy as she started grinding her pussy on top of Amy’s.

“Ohhhh,” moaned Amy as Tracy’s vulva pressed against hers.

Tracy’s clit was now exposed and throbbing, as their pussies continued rubbing against each other. She gasped in pleasure as her clit rubbed up and down over Amy’s cunt. After a few moments, Tracy leaned forward until her upper body was resting directly on Amy’s, and they started kissing passionately.

Amy and Tracy both moaned in unison as they fucked. Tracy increased the speed of her movements, heightening the friction between their genitals. Their breasts wiggled in unison, firmly pressed against each other, as they tribbed harder and harder.

“Ahhh, my bitch,” groaned Tracy as she felt more and more aroused. “Come for me, for me…”

Amy’s pussy was much more wet than Tracy’s, although more fluid was now slowly starting to stream out of Tracy’s vagina. Their vaginal openings rubbed vigorously across each other as Tracy’s fresh pussy juice dribbled onto Amy’s pussy, creating a messy, sloppy mixture of female bodily fluids.

“Oh, mistress, fuck me baby, fuck me harder!” Amy shrieked. She wrapped her arms around Tracy, grabbing her shoulders. Amy’s unbound wrist and ankle cuffs shook as Tracy continued thrusting against her.

Amy felt magical in that moment, as if Tracy’s body was melting into hers. The view of her gorgeous girlfriend – her mistress for today – on top of her, fucking her, was a sight to behold. The feeling was so exciting – it was almost like the purest form of lesbian intimacy. Two women’s bodies pressed firmly together, their moist pussies rubbing against one another, each one writhing in orgasm.

Amy was starting to come. She could feel the tingling in her pussy as her pelvic muscles tightened up. Tracy was also starting to feel a ticklish feeling in her vagina, as the sound of her wet pussy rubbing up against Amy’s grew louder and louder.

“Ohhh, God, harder, harder,” moaned Amy. “Yes, Tracy, I love you…you’re so damn beautiful…”

“Ohh, yes, my slut, you’re so hot, I love you too!” responded Tracy as they both approached orgasm at the same time.

“Ohhh, yeah, baby,” Amy grunted, as she futilely tried to buck her hips up into the air, restrained by Tracy’s body. She savored the delicate feeling of Tracy’s fleshy pussy lips rubbing up and down her cunt.

Thick, milky-looking fluid now readily trickled out of Tracy’s vagina, splattering across Amy’s hairy mound and pussy. However, there wasn’t a full blown female ejaculation for either of them. They would have to leave that for another time.

Tracy slowed her movements after they each finished climaxing. She looked longingly into Amy’s green eyes. They seemed like they were sparkling like never before.

“Well, that was nice,” remarked Tracy, softly kissing Amy’s chin. They eagerly locked lips again, their tongues wrapping around each other, mouths nearly engulfing one another.

Thick strands of saliva formed in between their mouths every time their lips separated. They continued kissing deeply for a couple more minutes, mouths slobbering all over each other.

Tracy brushed her left hand through Amy’s messy hair. “Mmm, that was an incredible session, Amy.”

“I agree, mistress. You are so skilled. I’m sorry I tried to disobey you earlier.”

“Well, you got your punishment, my dear submissive slut. You learned a valuable lesson today.”

“Oh, yes, mistress. Thank you for introducing me to your bondage fetish.”

Tracy laughed, knowing the whole thing was just a fantastic, free-flowing lesbian fantasy that was being enacted out in real-time with her girlfriend. Nonetheless, she appreciated the rawness of it, and how it gave her an avenue to introduce more kinky forms of pleasure to her less experienced partner.

“I love you, Amy. You’ll be so glad that you decided to start being my submissive slave girl. This will be an excellent learning experience for you, sweetheart.”

I don’t think she knows what she’s in for, thought Tracy playfully. She held Amy tightly, their tits pressing up against each other as they kissed more.

After a few more moments of deep, raw, passionate kissing, Tracy pulled away. “There’s one more thing, my love,” she said.

“Yes, mistress?”

“I need to tie you up – for the night. You are, after all, my little bitch, right?”

Amy looked at Tracy hesitatingly. “Um, tie me up? Where?”

“Oh, just right here, in my bedroom – I’ll tie you to the bed railing so you can sleep on the ground. It’s part of the deal, you know, of being in a submissive role.”

“Can’t I sleep on the bed with you, mistress Tracy?”

Tracy looked at Amy earnestly. “Now, you know that a bitch can’t sleep on the bed – she needs to sleep on the ground. It’ll just be for a few hours. Think of it as the final part of your…submissive initiation.”

Amy sighed, reluctant to engage in this unexpected final part – but she knew it was all part of the full BDSM experience. “Yes, mistress, you are right. I will sleep on the floor by your bed tonight.”

“Good girl. Go ahead now.”

Amy crawled off and sat down on the ground, near the lower-left corner of the bed. Tracy grabbed the chain leash that was attached to Amy’s dog collar, and locked the other end of it to the bed railing. Then she chained Amy’s wrist cuffs together, along with her ankle cuffs, so that her hands and feet were bound.

Amy managed a half-smile as Tracy looked at her lovingly. Tracy walked over to her closet and pulled out a large metal bowl – one that she had used often before. She placed it on the ground next to Amy.

“This is in case you need to use the bathroom during the night,” said Tracy.

That’s cruel, thought Amy. But I kind of like it…

“All right, sweetheart, I’m shutting the lights off now. I’ll wake you up in the morning…remember, we have the whole weekend ahead of us, so be ready. Ready to serve your mistress.”

“Yes, mistress. Have a good night.”

Tracy turned off the lights and laid back on the bed, pulling a warm blanket over her. She gazed at Amy adoringly for a while before dozing off.

Amy rested her head against the side of the bed, and she thought about her relationship with Tracy. It was starting to dawn on her that everything Tracy had done throughout the length of their relationship was leading up to this moment.

Tracy had always dominated Amy in some way or the other. She was Amy’s boss at work; she aggressively pursued Amy as a love interest; she convinced Amy to move into her apartment to make their relationship more intimate; and now she had made Amy her submissive sexual plaything. Everything had come full circle.

The BDSM fetish was now grabbing hold of Amy, just as it had taken over Tracy at some point years ago. She was starting to feel deeply aroused at the thought of being bound and restrained while submitting to someone else’s sexual domination. All it took was one experience to evoke these hidden desires from deep within her.

Amy suddenly giggled in delight, staring into the darkness as her naked, chained body sat uncomfortably on the rough carpet below. She sensed, in the back of her mind, that she was going to be in for a treat this weekend – and beyond. The best was yet to come.
