Once Bitten (CLOSED)

Mark's motions became more forceful and aggressive but he was fascinated with the sight of Sharon sucking off Mac's monstrous wolf cock. He sensed somehow that Mackenzie wasn't completely comfortable with his fucking Sharon and he felt a twinge of guilt. She was his lover, afterall, regardless of her form. However, his ego reminded him that she was enforcing a double standard. She remained free to fuck Sharon whenever and however she wished. Why shouldn't he be able to have some fun as well?

Mark's attention shifted back to Sharon, who suddenly shuddered and moaned loudly into Mackenzie's cock as she came. Her juices bathed Mark's cock and he suddenly exploded into Sharon's cunt.

As he came down from his orgasmic high, he slowly looked up at Mackenzie once again.
 
Seeing Mark cum, it was heart wrenching and orgasm enducing. Her body yielded up even more cum than before, feeling it fill Sharon's mouth and slicken her cock. She felt defeated, she just wanted to go home and curl up on the bed and die. Sharon was not helping as the slut continued sucking on her dark swollen cock. Mackenzie could feel the swollen head lodged in Sharon's throat and laughed as she realized it was stuck. She howled and laughed, as Sharon's breathing became ragged as the swollen head was lodged in her throat.
 
Mark stared in horror for a moment as Sharon gagged and began turning blue. He withdrew from Sharon's pussy and scrambled to the front to try to dislodge Mackenzie's cock from her mouth. Sharon's mouth was completely dry now, which wasn't helping things. Mark's medical training had never prepared him for something like this, but he quickly lowered his head and began licking and sucking Mackenzie's still swollen cock. Doing his best to lubricate the cock and not thinking clearly about Mac's wolfen anatomy, Mark only made things worse by causing her to grow harder.

Sharon was practically purple before a sudden, violent cough forced her mouth open enough to pop off Mac's member. Her eyes filled with tears and gasping for water, Sharon crawled away toward her car, desperately seeking her gym water bottle, which might still have some water in it.

The sight of the now revealed and massive cockhead gave Mark pause. He stared, wide eyed and in awe of the massive dark colored tool, fresh white cum oozing freely from it.
 
Mackenzie's swollen head was blocking oxygen, which could have been funny if Sharon wasn't frantically struggling making the tip swell and causing more problems. Worse still when Marks tongue touched her, it was like fire, but somehow perhaps due to her cock spasming in pleasure the head finally dislodged.

Sharon coughed and made her way to her car. Mackenzie just looked at Mark, silently begging him to continue as her dark swollen prick continued to ooze wolvine cum.
 
Mark could read the desire in Mackenzie's eyes. Leaning forward, he took her massive wolf cock deeply in his mouth. He sucked and slurped, eagerly seeking to pleasure her. Had his mind been working properly, he would have been repulsed by his actions, but his only desire now was to please Mackenzie and do whatever she wanted.

His eyes met hers, flashing the hunger for her he felt. Using his own impulses from when he was in her position as a guide, Mark moaned into the cock, his tongue swirling around the head that was now buried deeply in his throat. One hand gripped the shaft and worked it as he sucked at her, the other hand reached between her legs to tease and rub her massive wolf testicles.

Part of him wondered what it would be like to please her if she had both a cunt and cock at the same time.
 
She adored him, and she was completely relaxed. Unlike when she practically raped Sharon's mouth, she let Mark dictate the pace. He seemed driven to push past his limits as tried to take her as deeply as Sharon had. It was so completely different from Sharon, Mac tolerated Sharon, she yearned for Mark. Her eyes flicked occasionally to the full moon, wondering what tomorrow night would bring.

Her mind was hazy, as she knew she would recall very little of her actions, only how she felt. For a moment she felt as if she needed to be somewhere else, with someone else...
 
Mark continued happily sucking away, pleasuring her, taking her in deeply and teasing her with his tongue. He was completely on autopilot now, thinking only of how to please her.

The sky began to lighten and he knew morning was approaching. As tired as he was, he increased the vigor with which he serviced her, sucking harder, faster, his hands becoming more insistent, frantic in stimulating her. He could feel her cock twitching, trembling. The change was coming soon and he'd continue to pleasure her the entire time, as both wolf and woman.
 
The change trembled within her, the pain intermingling with the pleasure to create an entirely new and complex sensation. She shivered as her orgasm intermingled with the change, the fur fading, muscles and bones shifting her cock shifting from massive black canine manificense shrinking turning pinkish red slowly gaining more human proportions, the rest of her body gaining humanity as her spasming prick the last to change, and even then when Mackenzie finally looked down upon her lover, her clit or what had been her cock was nearly the size of her thumb and hickey colored red. Her pussy, legs, and belly, were drenched in cum.

She shook her head trying to wrap her head around the intense emotions and images flooded her mind. Unable to believe half of them even as she looked down to see Mark sucking her clit.
 
As Mackenzie's body began the change, her orgasm erupted, flooding both of them with the remnants of her milky seed. Mark felt her shrink in his mouth and soon his face was pressed against her pussy, feverishly sucking on her enlarged clit.

The morning light seemed to cause the spell of the night to pass and he slowly came to his senses. Looking up at her sweat, dirt and cum covered body, he found himself disoriented, his memories jumbled.

"Mackenzie," he spoke, his voice a hoarse rasp, "what happened? I... remember you changing... and then... this..."

Somehow he knew he memories were no better. It was as if they were somehow linked and where the memories of one were fogged and hazy, so was the case for the other.

He ran his hands over her body, remaining on his knees and rubbing her adoringly. Her entire body still radiated strength and raw power, which was somehow strangely comforting to him.
 
"I tend to remember feelings more than actual events," her voice was a raspy as her tongue ran over her lips. Her body tingled, she felt reborn, and covered in goo, she kind of looked it. She was drained, yet not exhausted, as she slowly sat up and ran her fingers along his face.

"We could record things," she suggested. She had a sense of having left something unfinished, but the warmth of the sun was making her mind more human and less canine.
 
Mark nodded as he rose to his feet. "That's... a good idea. We can set up a video camera on a tripod here tomorrow... er, tonight." He whinced at the rising sun.

They gathered their clothing and made their way back to the car. Once home, they showered and curled up together on their bed and slept for several hours. When they finally work, things almost seemed normal. Mark offered to cook lunch and went into the kitchen.

As he made lunch, his mind drifted back to the drug he'd been giving Mac. It seemed to make her transformation more difficult last night. Perhaps an extra dossage would completely suppress the beast. Perhaps tonight she might not change if he administered more.

He mixed Mackenzie's favorite protein drink and slipped a triple dose of the drug in.

"Mackenzie, lunch is ready," he called.

When she joined him, her place was already set and her drink and sandwich were waiting for her.

"I might head over to my gym in a little bit," he mentioned.
 
She smiled at his concern, and wondered about his motives behind the gym. Sure she was in prime physical shape but he could gain a hundred pounds and she'd still want to fuck him silly. She simple smiled and encouraged him to do whatever he wanted to do. The food tasted strange, but she figured he cooked things differently than her and that must be it.

Mackenzie felt out of sorts all afternoon, she took a leisurely hot bubble bath, her skin felt refreshed, tingle, even more heightened awarenes than usual. It was strange to not have to shave her legs, and she cautiously played with her swollen clit. It was marginally smaller now, closer to the size of her pinky rather than the thickness of her thumb. It was tender, but not overly sensitive, and the play of warm water was a subtle sort of teasing.

She slide her fingers down to explore her hot pussy. She felt a need to confirm her feminity as she masterbated in the warm water. She wondered what a transformation in water would feel like. She laughed at the image of a smelly wet dog, and let her pleasure unwind slow and easy.
 
As Mark worked out, he struggled to recall the events of the previous night. Things remained a blur to him and he wasn't sure if this was a good thing or not. He wondered what this night would hold. Perhaps it might be best to be away from her if the drug doesn't work and manage to suppress her transformation tonight.

On the way home, Mark stopped at an electronics store and picked up a video chip with extra storage capacity for his video camera. He'd need it for the video of tonight's events.

--------------------

Sharon stared nervously as the sun began to dip in the sky. She knew Mackenzie would call soon, bark orders at her, telling her where to be and usually whispering something dirty about how she intended to use Sharon that night. The disturbing part was how Sharon had grown to secretly long for this. Her rational mind screamed at her how wrong this all was, but she couldn't resist the urges and feelings.
 
Mackenzie took to bed after her bath, she felt sluggish, and out of sorts as she climbed into bed. She had forgotten how much transformation took out of her, and she sent Sharon a text with instructions. She didn't feel like talking to the bitch, but reminded her not to bother with panties, and Mackenzie wasn't going to be replacing any torn clothing.

When she woke up she slipped a light blue silk robe on and wandered out to the forrested area by Mark's house. She felt a sense of deja vous and heard a couple fighting and fucking. They sounded familiar....

Katherine had been on him all night and day, he'd called in sick to work, and when she'd wanted to find the spot, well he'd been relunctant, one blow job later and he'd agreed. Now she was all over him, pressing him up against the tree. She was strong and aggressive, and he'd never really thought of himself as submissive until now, and he tried to resist liking it.

"Was it here?"

"Over there?"

"Did you like fucking her this much?"

"Do you want me to bite you like she did?"


Phrases drifted to her and Mackenzie felt light headed as that night came flooded back to her. She recognized the scent of them long before the voices clicked in her head. It was the last phrase that troubled her the most, she could not recall biting the woman...katherine was her name. Yet at the same time she understood all too well what was going on. She ran away blindly feeling sick emotionally and physically. She threw up in the bushes outside Mark's house and went inside. She rinsed her mouth out with water, then fixed herself a protein shake, knowing she would need the energy for this night. She stood over the sink and raked her nails up and down her arms, trying to feel anything other than revulsion as blood dripped down and her skin healed.

The process was cathartic, and she finally understood why someone would cut themselves. She frantically cleaned up knowing Mark would be home soon. The scent of blood lingered in the air, and she stretched out on the couch trying to get a little more rest before he got home. Ignoring the vibrations of her cell phone saying she had missed calls, messages, and other.
 
Sharon got Mackenzie's message and tried calling a few times. She was tired of being treated as a piece of meat. She wanted Mac to acknowledge her and at least be more respectful. She was giving herself willingly... WILLINGLY to Mackenzie now and simply wanted to be treated like a partner and not a slave... at least prior to the actual act itself.

Frustrated, Sharon drove to Mackenzie's apartment. She was wearing an old t-shirt and gym shorts without a bra and panties. She marched up to Mac's door and knocked. As she waited, she glanced up at the rapidly setting sun. They were scheduled to meet in just under an hour.

As she waited at the door, she found herself becoming aroused in anticipation.

"Mackenzie?" she called through the door.

-----------------

Mark was running late. He quickly dialed Mac and left her a voice mail, saying he'd meet her in the woods, same spot as the night before. He asked her to bring the video camera too.

The vibrations finally woke her, her skin and hair dried. She felt stronger but still on weak side and famished. Mackenzie was about to raid the fridge when she heard someone at the door. She plodded obediently to door, wondering if Mark was coming home early for some last of sunlight sex. She was excited at the thought, and dissapointed when she smelt it was Sharon.

She flipped open her phone and dialed voicemail listening to the messages letting Sharon stew at the door. She almost laughed at Sharon's indignant messages, but wondered about the camera Mark mentioned as she finally let Sharon in.

She allowed Sharon to ramble and fume before slapping her firmly across the face, pushing her roughly against a wall, and kissing her deeply. "Respect is earned, and trust me spreading your legs willingly like a bitch in heat is not worth my respect."

Mackenzie growled and pressed her body against Sharon's, "Go strip and lie down." Mackenzie pointed to a door.

Sharon opened her mouth to protest but finally stormed off to the spare bedroom, at first she was pissed it wasn't where Mark and Mackenzie made love, but eventually she was grateful it wasn't. The wait seemed to take forever as she laid naked and trembling on the bed.

Mackenzie downed another protein shake, ran her fingers quickly through her thick dark short hair, and strode down the hall to the spare bedroom. She opened the door glad to see Sharon spread out for her enjoyment. Mackenzie dimmed the lights to near nothing, the fading sunlight barely illuminating the room. Mac had recalled Mark mentioning setting up the camera in spare bedroom to test it out, and it was still there, and she managed to hit the record button without letting Sharon in on it. Mackenzie slowly dropped her robe and noticed Sharon's reaction.

"You are such a bitch," Mackenzie barked the words.
 
Sharon trembled at Mac's words, but her body ached with need for release at the same time. She stared in awe at Mackenzie's powerful, flawless body.

"Mackenzie," she spoke, her voice cracking and wavering slightly. "I... I'm sorry. Please... I... I'll do anything. I just need you... to be around you... to be with you. I'll do anything... anything... to be with you. Please?"

Sharon started to sit up, but paused, unsure if this would anger Mackenzie further. She thought about crawling to her on her hands and knees, eating Mackenzie's pussy as she knelt before her. She'd let Mac use her, curse at her, abuse her. The change would come soon enough and then Mackenzie, as the Wolf, would get really rough with her.

Her body ached with anticipation.
 
"Shut up," the word was deadly serious as Mackenzie took two silk ties and carefully tied Sharon's hands to the head board. Mackenzie forced Sharon to suckle her breasts, not paying attention to the time or the fading light. The pain stabbing her in the back, the base of her skull, and between her eyes. Pinpoints of pain stabbing in her head and she howled in the horrific pain of it all. Her breasts shrinking rapidly, muscular torso replacing. It seemed to go in segments, her nails and hands bursting forth, the pain worse than any migraine she experienced. Her body seeming to resist the change even as it sought it out. The fur rapidly growing, her face contorting, altering. It seemed like forever, but only the video would tell exactly how long it had taken.

Her tongue lolled, droooling over Sharon's face, as the swollen dick rubbed against Sharon's belly. Face to face with the beast, as it seemed to smile, and the fat cock took no time in invading Sharon's hot cunt. The beast delighted in her pain, her screams, her pleas. Fucking her so hard her head was knocking against the headboard.
 
Sharon obediently obeyed Mackenzie's orders and laid back as she was tied down to the bed. She had just begun sucking on Mac's cunt when the change came. She watched, wide-eyed and in wonder as it happened, Mackenzie struggling as it violently overcame her. When her monstrous wolf cock grew right into Sharon's open mouth, she gagged at first, struggling to breathe.

Mackenzie the wolf quickly withdrew her cock from Sharon's mouth and plunged it into her cunt. Sharon moaned loudly, her body eagerly embracing the fucking she was receiving.

"Ohhh, ohhhh, Mackenzie... ohhhh, ohhh yeah! Yessss! Please fuck me! MMMM! Harder! Ohhh yeahhh, harder! Mmmm!"

The Wolf responded, her powerful thrusts pounding Sharon's skull against the bed's headboard. It hurt, but Sharon ached for release and endured. She stared into the beast's eyes, savoring the lust she saw there. When the Wolf suddenly growled a low, menacing snarl, Sharon recalled that staring a dog or wolf directly in the eye was a challenge.

"Oh my God, no! No, Mackenzie, no! I... I didn't mean..."
 
Mackenzie's paws pinned Sharon's shoulders to the bed, as she was determined to show her bitch who the boss was. She withdrew her cock and moved up, snarling as she fed it to Sharon, shoving it roughly down her throat, making her remember how easy it would be for her to suffocate, and that between Mac and Mark it would look either like an accident, or a suicide.

Not that the wolf had such rational thoughts as it slide it's thick cock down her throat enjoying the tears rolling down her face, as it thrust past any gag reflex to fill her before withdrawing letting just the swollen head remain in her mouth. It was deliscious in a way Mac could not begin to describe. Some part of her realized Mark was alone out in the woods, but the greater part just didn't care as long as her cock was getting sucked.
 
Sharon coughed and sputtered as Mackenzie thrust her cock deeply into her small mouth. Her face turned blue as she struggled to breathe. Soon the Wolf got into a rhythm with its thrusts and Sharon's mouth became accustomed to the motion. Sharon was beginning to truly enjoy the experience now, moaning loudly into the monstrous cock filling her mouth, causing vibrations to shudder through it. Her own pussy was now dripping wet again and Sharon reached a free hand down to pleasure herself. Her eyes rolled back into her head and she pressed her breasts against the Wolf's balls, anus and tail. Sharon's mind swam, delirious with ecstasy. She loved this and the sense of shame had completely faded now.

When the Wolf finally erupted and it’s hot cum poured down her throat like molten lava, Sharon practically inhaled it and sucked her clean. Her entire body tingled, feeling alive and suddenly recharged. The Wolf withdrew and growled laughingly at Sharon who appeared at first to be struggling to swallow the last of the seed. Sharon's eyes suddenly snapped open and met the beast's, challenging her again to see what else it could dish out.

The words that came from Sharon's mouth next shocked her as she said them, yet rarely had she spoken truer words.

"Mmm, Mackenzie," Sharon purred. "I fucking love the taste of you. I want to be like you. Please! I want to be your bitch, now and forever!"
 
If she could have spoken she would have said Sharon was, but she sensed the implication behind the words and growled low and mean. Mackenzie's claws digging into Sharon's shoulders, inflicting pain however unintentional. The scent of blood further aroused the wolf, and suddenly Mac was just rubbing her cock against Sharon's body, determined to cum all over her, mark her territory so to speak.

She could smell Sharon from a mile away, and the bitch was in heat. It was arousing and infuriating that this stupid bitch was ovulating even as her own womb lay empty. It pissed her off that neither of them could seemingly have kids. It pissed her off that she was cursed with this body and Sharon seemed to crave it. She hated Sharon for being human, and a small part loved her for being her private bitch.

With that mixed up flurry of emotions she erupted, thick wolvine spunk erupting all over Sharon's body.
 
Sharon's entire body shook with orgasm as the wolf cum coated her. She laid moaning, gasping and cooing, longing to rub the sticky cream into her skin.

"Yesssss yesssss," she cooed.

Sharon touched the Wolf's face as she leaned over her, running her fingers along the beast's powerful maw, hoping to make it bite her. She bucked her hips and rubbed her cunt against the Wolf's cock and balls, seeking to stimulate them again. She growled loudly now.

"C'mon, Mackenzie! Fuck your bitch again! Give it to me! Give it to me!" she groaned through clenched teeth.

Mac felt peculair about her bond with Sharon, it was sick and twisted, yet as the animal it seemed only natural that this bitch be the recepticle for her cock. She hated it, hated herself, and some part of her vowed to find another way, to deal with the sexual hunger of the beast.

Sharon's words were peripheral, as Mac pulled her head away from the bonds, she had very nearly opted to rip them with her teeth, but seeing Sharon helpless to move, seemed perfect somehow. Mac's nails raked slightly down Sharon's sides, leaving thin trails of blood. The mess was secondary to Mac's need to penetrate and punish the bitch.

Sharon seemed to enjoy whatever orifice Mac used, so she opted for cunt as it felt slightly better, her sticky wet cock slamming into the well used pussy. She knew Sharon hadn't been with any other man just by the scent, and she knew Sharon had been either masterbating a lot or using some massive toys by how loose, and sloppy her cunt was.

This information the wolf filed away for Mackenzie to use later. For now she just plunged in and out, frantically trying to expunge her fear, rage, desire, into Sharon's body.
 
Sharon was in heaven and hell at the same time. Her body screamed for release, but she loathed herself for loving this sick, twisted act. She yelped in pain as the Wolf raked its claws down her sides.

"Bite me, bite me, bite me, please!" she pleaded softly.

Orgasm after orgasm wracked her body and she hoped the night would never end. She watched with fascination as the Wolf pounded away at her cunt. The sight, sounds, smells and feel of the experience burned into her brain as her world spun completely out of control.

At last, Sharon screamed, her cries echoing throughout the complex. She could stand no more, her body finally broken and begging for the Wolf to stop.

"No... no... please... n-n-no more..."
