Gemma Ch 01 3

"What are you?" Zoe demanded, as she thrust her six -inch rubber cock down into Gemma's gushing pussy.

"A slut," she panted in reply, her eyes rolling back in her head like a depraved junkie taking a hit. "I'm a slut."

Crack! Without any warning, Zoe's hand swiped hard and fast across Gemma's face. She looked up, shocked, her cheek burning with pain. It wasn't the first time she'd felt the venom of her young mistress's palm on her pale freckled skin, but until now such strikes had been reserved for her tits and arse.

"What kind of slut?" Zoe snarled, biting her down on her plump lower lip.

Gemma hesitated. She knew exactly how she was expected to answer, but, as always, in those few seconds before she uttered the words, a guilt stricken voice screamed inside her head, telling her not to do it.

"A cheating slut," she whispered quietly. "I'm your filthy, nasty, married, cheating slut."

Zoe cackled and started smashing her hips back and forth even faster. Gemma's pussy squelched loudly in reply. She was now on the edge. She clenched her eyes tightly shut, knowing that she was about to experience an intensity that until recently she hadn't believed to be possible.

"Fucked!" she screamed. "Fuck! Fuck! Fuck!"

Just an hour later Gemma was back home standing in front of the bathroom mirror, her long red hair wet from the shower. She inspected her body. Her skin was so white it almost seemed translucent, except for the patches that Zoe had left on her tits and butt cheeks. The fresher of these glowed an almost fluorescent shade of pink, but the older ones had turned into an ugly mixture of purple and yellow.

She sighed heavily, looking at the mark on her face. It wasn't too obvious yet but she feared it may worsen in the coming hours. So far, she'd excelled at hiding her markings from her husband, Kevin - he'd not seemed to realise that it had been several weeks since he'd seen her naked - but she feared this fresh abrasion might be harder to conceal.

Her eyes started to well-up, as she applied a thick layer of foundation against her cheek. During her first marriage she'd repeatedly been the victim of infidelity, the fact that she was now the perpetrator of such acts made her feel sick to the stomach.

"Gem?" she heard from the hallway, the cheery voice of her step-daughter Penny. "You gonna be long? Dinner's ready."

"I'll be right down," she replied, wiping a tear from her face. Taking a deep breath, she then managed to pull herself away from the mirror and started to get dressed. By the time she arrived downstairs in the kitchen her weepy demeanour had been replaced with a beaming smile, expertly hiding her shame. She took a seat between Penny and Penny's twin brother, Shaun, then asked her happy little family how their days had been. Kevin fired in to a witty anecdote about his painful morning commute to the office, resulting in a flurry of laughter around the table.

Just as the normality of this typical Thursday evening was starting to shift Gemma's mind away from Zoe, she felt a buzz in her pocket. Somehow she knew it was text from her young mistress. It can wait, she told herself, firmly, as her stomach fluttered. Family time, is more important.

"Ooh, I need a wee," she announced, her resolve crumbling less than a minute later. She darted quickly out of the kitchen and down the hallway to the toilet. Her hand trembled as she locked the door and pulled the phone from her pocket. A picture of Zoe's perfectly bald pussy appeared on the screen. "Get into the office early tomorrow." the accompanying text demanded. "I want you to eat this before anyone else arrives."

"Yes Mistress." Gemma quickly tapped in reply, before her hand disappeared into her panties.

---

The next day, Gemma woke up with a mix of dread and anticipation. She knew she had to get to the office early, and the thought of Kevin waking up and finding her missing stirred a potent cocktail of guilt and arousal within her.

She slipped out of bed, her heart racing as she tiptoed through the silent house, her body still throbbing from Zoe's relentless pounding the night before. Upon arriving in the carpark, she practically sprinted to the office door, her knees trembling as she tapped in the code to unlock it.

Their usual meeting place was a supply closet tucked away through a small labyrinth of dimly lit corridors. "Good morning, slut," Zoe purred, her eyes glinting with a sadistic sparkle. "I trust you're hungry."

Without waiting for a response, she spread her legs wider, her labia parting to reveal the pink, swollen flesh within. Gemma felt her mouth water. She dropped to her knees - the dingy decades old carpet doing little to cushion her fall - and leaned in to enjoy her breakfast, eagerly lapping at Zoe's glistening pussy.

The heat and tension built rapidly as her tongue danced around her young mistress's clit. Just as Zoe's body began to quiver with the promise of an orgasm the harsh beep of a message tone echoed through the small room, jolting them both back to reality. "Who's that?" Zoe breathed, clearly annoyed at the intrusion.

Gemma pulled her mouth away from Zoe's pussy and reached for her phone. "It's Kevin," she murmured. The message on the screen was innocent enough: "Morning babe, where are you?"

A wicked smirk spread across Zoe's face as she sat up, placing a hand on Gemma's shoulder. "Do you two still fuck?" she quizzed. Gemma gulped, scared that Zoe might not like the honest answer that she felt compelled to give.

"Yes," she confessed. "Sometimes, not often."

Zoe's smile grew more predatory. "Is he good?" she purred, sliding her fingers down to pinch Gemma's nipple. "As good as me?"

"No," Gemma quickly confirmed. "Nowhere near..."

"How big is he?"

"I...I don't...average I guess."

Zoe's eyes narrowed as she seemed to process this information. Gemma could sense she was conjuring some plan. "We're going to my apartment at lunchtime," she announced, pushing Gemma away as she stood up and started to dress.

---

As the morning dragged on, Gemma struggled to focus on her work. It felt like she had unfinished business. Her mind was filled with images of Zoe's naked body, the taste of her, and the promise of what was to come at lunchtime. When the clock finally struck noon, she stood up from her desk and walked swiftly down the stairs and through to the carpark, her pussy already wet and eager.

Once they arrived at Zoe's apartment, the young woman wasted no time. She pushed Gemma down onto the leather couch, her hands roaming over her curves like a sculptor admiring her own creation. "I need to show you who's in charge," she murmured, her voice thick with desire.

Gemma nodded, unable to speak, her breath coming in shallow gasps as Zoe began to strip her naked. The anticipation was unbearable, her body trembling with excitement and fear.

"On your hands and knees," Zoe ordered, her voice firm and commanding. Gemma obeyed, her heart racing as she presented herself to her mistress. She felt Zoe's hand on her back, her fingers tracing the curve of her spine before delving into her wetness. The first two digits slid in easily, stretching her open, preparing her for what was to come.

And then, without warning, Zoe's fist was there, her whole hand attempting to violate Gemma's pussy. The older woman screamed, her body jolting with the sudden intrusion. It was unlike anything she had ever felt, a mix of pain and pleasure that was almost too intense to handle.

"You're mine," Zoe growled, her eyes locking on to Gemma's via the mirror on the other side of the room. "You're mine to fill, to use, to fuck."

Gemma could only whimper in response. She had never felt so utterly consumed by another person, so completely owned. And as Zoe's fist plunged deeper, she knew that she would do anything, absolutely anything, to keep feeling this way.

---

Over the next few weeks, the fisting sessions grew more intense and frequent. Zoe pushed Gemma's boundaries almost every time they met, and the older woman's pussy began to stretch and accommodate her young mistress's hand, allowing for deeper, more vigorous penetration.

The pain remained, but so too did the unrivaled pleasure that made her toes curl and her eyes roll back in her head. Each rendezvous became a ritual of submission and ecstasy, with Zoe's fist becoming a symbol of her absolute dominance over Gemma's body.

Gemma believed that for Zoe this new proclivity was a way for her to further differentiate herself from Kevin, establishing an even larger gulf in the thrill that existed with each of her two lovers. There was some truth in this assumption, but a far more sinister ulterior motive was soon to be revealed.

"I want you to fuck him tonight." Zoe texted one Friday evening, shortly after a particularly heavy session between the two women.

Gemma frowned as she read the message, feeling somewhat confused by the instruction, and a little anxious as a result.

"OK." she replied, her pussy still pulsing from the fisting it had just endured. "If that's what you want."

That night, as she lay next to her unsuspecting husband, she felt a strange mix of emotions. Guilt tugged at her conscience, but a darker, more primal urge to satisfy her mistress's command grew stronger. She reached over and gently began to caress Kevin's cock, feeling the familiar yet underwhelming girth. As he stirred and grew hard, she slid on top of him, her body moving mechanically through the motions of passion. But as she took him inside her, she realised with a jolt that she could barely feel him. Her pussy, now accustomed to the stretch and fill of Zoe's fist, felt almost empty with his average size. The disconnect was profound, and she found herself faking her moans and gasps to keep the charade going.

Kevin's thrusts grew more and more erratic. He was obviously trying to reach climax, but his cock was no match for the stretched cavern that had become of Gemma's pussy. She could feel him getting desperate, his strokes becoming almost painful in their urgency.

It dawned on her that she had become so loose from Zoe's fisting that her husband was having trouble reaching his peak. The realisation sent a shiver down her spine, a thrill of illicit excitement mixing with the guilt and embarrassment.

She moaned louder, grinding her hips down onto him, trying to create some friction for him, but all the while her mind was racing with thoughts of Zoe's hand buried deep inside her, the way her walls clung to those invading fingers. It was a stark contrast to the ease with which Kevin slid in and out, and she couldn't help but feel a sense of detachment from the man she had sworn to love and cherish. Yet, the very idea of her own betrayal, the fact that she was cheating and lying to him, only served to excite her more, making her wetter, her body more responsive to his touch despite the lack of fulfillment it brought her. The power dynamics had shifted so dramatically that even in her own marriage bed, it was Zoe who ruled her body and her desires.

Finally, unable to take the frustration any longer, Gemma reached down and wrapped her hand around the base of Kevin's cock, her grip tight and her strokes quick. It didn't take long before Kevin offered out a load grunt and shot his load, spurting it all over her stomach and breasts. She felt a twinge of sadness as she watched him, his body shaking with pleasure that she hadn't been able to provide with her pussy alone

After he had finished, she rolled off of him, the juxtaposition of his warm cum on her skin and the emptiness within her making her feel both used and unfulfilled. As he drifted off to sleep, she lay there, her hand idly caressing her own swollen clit, thinking of the text she had received earlier. "I want you to fuck him tonight," Zoe had said. It was clear now that this was part of her mistress's plan, to make her feel this way, to remind her of her true place. And with that thought, she slipped a finger inside herself, feeling the gaping hole that Kevin had been unable to fill, and began to masturbate with a fervor that was fueled by the agony of her own treachery.

---

Zoe messaged early the next morning, demanding to know if her instruction has been followed. Gemma's cheeks flushed as she composed a text back, detailing her unsatisfying encounter with Kevin. She described the stark contrast between his average size and the fisting she'd grown to crave, and how she'd had to resort to her own hand to find release.

"Excellent." Zoe quickly replied. "You know what this means don't you?"

Gemma felt a sudden surge of panic as she read Zoe's message. "What do you mean?" she answered, her thumbs trembling over the screen.

Zoe's response was cold and calculated. "You're ruined for him now." it began. "That pussy is mine. He'll never be able to give you what I can, or even what he could before I ruined you. Neither of you will ever enjoy your sex like you used to. I'm sure there might be ways you can satisfy eachother. Oral sex, handjobs, maybe anal even, but as far as real sex goes - your husband's cock inside your pussy - there won't be any pleasure in that anymore. It's over."

A chill ran down Gemma's spine as she thought about her husband, about the life they'd built together. Was this really true? Had she really irrevocably destroyed her husband's ability to satisfy her?

"Your pussy is a fuck-hole now." Zoe continued. "Not a love-hole. The only thing it craves is pain and fullness. And this is just the beginning. I'm going to stretch you even more."

The cruelty in her words was like a punch to the gut, but even as the reality of the situation sank in, Gemma's clit throbbed with an unwanted arousal. For once, however, her guilt seemed capable of conquering her lust. She squeezed down tightly on the power button of her phone and waited for the screen to turn black.

---

Gemma wished that pausing the rest of her life was as easy as the ten second press of a small black button. It wasn't, she knew, and a busy Saturday was waiting for her.

First on the list, was to take Penny shopping. Her step-daughter was starting her first full time job in a couple of days and needed a whole new wardrobe. Trudging through a busy shopping mall was the last thing Gemma wanted, but disappointing Penny would be yet another betrayal of her family.

As they wandered through the racks of clothes, Penny's excitement was palpable, her laughter echoing through each shop as she held up various outfits for Gemma's approval. Despite the chaos of the mall and the weight of her secret, Gemma couldn't help but feel a comforting warmth being in her step-daughter's company. Things had been difficult early on in their relationship, but in recent years, particularly after Penny had finished school, they had grown very close.

After an hour or two, they took some respite from the shopping and visited the food court for a coffee and slice of cake. Surrounded by the murmur of shoppers and the smell of fast food, Penny chattered away about her new job and the friends she had made during the long drawn-out selection process. Gemma nodded and smiled, doing her best to listen despite her thoughts constantly drifting back to Zoe's apartment and the fisting she had endured the night before. Her pussy, still tender from the rough treatment, throbbed at the memory.

Shortly after their spree resumed, they passed by an Ann Summers store, its windows displaying a range of highly sexualised lingerie that seemed to beckon to Gemma from the shadows. A particularly lifelike mannequin wore an outfit similar to one she'd seen Zoe wear on many occasions.

Reaching into her bag, almost subconsciously, she felt the cold glass of her lifeless phone against her fingertips. The urge to read the text messages that Zoe had inevitably sent grew stronger with each passing second. Despite its powerless state it seemed that the phone was calling out to her, telling her that Zoe was waiting and growing impatient.

"I need to use the toilet," she announced, a sudden surge of adrenaline causing her voice to crack a little as she spoke.

"OK," Penny replied as cheerful as ever. "I'll come too."

"No...I might be a while."

With a forced and awkward smile she then thrust her credit card into her step-daughter's hand, told her to get whatever she needed and rushed towards the nearest toilet. Her heart was pounding as she sought out an empty stall. Once safely behind the locked door she hastily turned on her phone, and waited for it to come back to life.

Her pussy now tingled. This sudden surrender to temptation was absolute, and had brought her an almost overwhelming sense of euphoria. Her guilt and shame had dissipated, almost entirely. It wasn't lost on her that she had just abandoned Penny, but she no longer cared. Her only priority was to serve and please Zoe.

Expecting to find several messages awaiting her, she was a little disappointed to see that there was only one. She tapped it open, believing that she was ready for anything it might throw her way.

"Does it sadden you to think your cunt is ruined?" it began. "It shouldn't, because it's not...it's all about perspective.

"For men like Kevin it's no longer usable, but not all men are like Kevin, are they? Some men are bigger. Much bigger. For them, as you're going to discover very soon, your stretched out hole is perfect..."

Gemma felt the colour drain from her face as she read this. The implication was clear: her young mistress was going to push her even further beyond the boundaries of her marriage and into a world of uncharted depravity. The thought of another man's cock, filling her now-stretched pussy was a terrifying prospect, but as she sat there on the toilet, surrounded by crude graffiti and the foul stench of urine, she resigned herself to the realisation that any attempt at resisting this dramatic escalation would be futile. She couldn't even get through a simple shopping trip without succumbing to Zoe's allure.

The words of the message were still on her screen, burning into her eyes. Rather than fighting Zoe's plan, she decided to embrace it. One hand went to her gaping pussy, while the other tapped on the screen.

"No, it doesn't sadden me." she wrote, answering what she knew had been a rhetorical question. "I am ready for whatever you have planned for me."

Her trembling hand found her clit, already swollen and begging for attention, and she began to rub it in slow, deliberate circles. The memory of Zoe's fist pummeling into her pussy played on repeat in her mind. The sounds of the busy bathroom coming from the other side of the door seemed to fade away as she focused solely on her own pleasure, her breath hitching in her throat. The fear of being overheard only served to intensify the moment, and with each stroke, her body grew tighter, the pressure building like a coiled spring ready to snap. And then it did.

The orgasm ripped through her with hurricane-like force. Her body bucked and shook on the toilet seat as she stifled a scream by burying her face into her arm. As the tremors subsided, she realised with a start that she had just masturbated in a public bathroom, a stark reminder of the depths she had sunk to in her submission to her young lover. She quickly stood up, pulled up her panties, and stepped out of the stall, her legs wobbly as she made her way back to Penny.

---

The car journey home was a tense, uncomfortable affair. Gemma's mind was a whirlwind of carnality and guilt, her thoughts fixed on the hasty promise she was now regretting having made in the toilet cubicle.

"What are you wearing tonight?" Penny asked, snapping Gemma back to reality.

"Oh, just something comfortable," she replied. "Maybe jeans and a jumper."

It was her sister-in-law Sarah's birthday, and the whole family were heading out for a meal. It wasn't something she'd been particularly looking forward to earlier in the week, but now considered it a very welcome distraction. As they arrived home Gemma's phone buzzed three times in rapid succession. Quick fire messages like this were Zoe's hallmark.
