One evening, coming back from work, my girlfriend is bitten by an unknown creature. His wounds heal normally within 2 weeks, apparently without repercussions. However, on the first full moon night after the accident, she turns into a werewolf-like creature. She grows to be more than two meters tall, big and muscular. She is covered by a thick black fur. Her breasts expand and develop additional udders on the abdomen. Her vagina also changes: her clitoris grows into a huge canine penis, with a big knot at the base, her vagina tightens until it disappears and two large testicles are contained in a heavy and hairy scrotum. Despite the transformation, she maintains her identity and consciousness, even though she is influenced by her animal instincts, as well as an unpalatable sexual appetite. Only during full moon she transform, and return human the following morning, except for some details: now she no longer has a vagina but a small canine penis contained in a hairy sheath, and under small balls contained in a scrotum. The transformation is repeated at every full moon. Because we love each other, we will find a way to live together despite his appearance.

Chapter 1: Introduction

Sarah

"Adam, I'm home!" I called out, tossing my keys onto the side table in our cozy apartment. The soft glow of the setting sun painted the living room in warm hues, casting long shadows that danced with the gentle breeze flowing through the open windows. The scent of fresh paint and new upholstery still lingered, a testament to our recent nesting phase.

Adam emerged from the kitchen, a glass of red wine in hand. "Hey, babe. How was your day?" His eyes scanned me, concern etched on his face. "You're a little pale.

Everything okay?" Adam asked, handing me the glass of wine. I took a sip, letting the rich, velvety liquid coat my tongue before swallowing. It was exactly what I needed after the day I'd had.

"Yeah, just a long one," I replied, kicking off my heels and sinking into the plush couch. "I got bit by something on my way home, though. It's nothing, really. Just a scratch." I showed him my arm, where a series of faint, red welts marred my skin.

Adam's eyebrows shot up. "A scratch?

Sarah, that looks pretty nasty. Let me take a look," Adam said, sitting down next to me and gently taking my arm in his hands. He examined the wounds, his brow furrowed in concentration. "You should probably get a tetanus shot, just in case. And maybe we should go to the ER, get it checked out properly."

I rolled my eyes, pulling my arm back. "Adam, I'm a nurse. I know what I'm looking at. It's just a bite. I'll keep an eye on it, and if it gets worse, I'll go to the doctor.

I promise," I said, giving him a reassuring smile. "For now, can we just... relax? I've had a long day, and all I want is to put my feet up and not think about work or bites or anything else."

Adam looked like he wanted to argue, but he must have seen the exhaustion in my eyes because he relented, putting an arm around my shoulders and pulling me close. "Alright, babe. We can relax. But if you start feeling feverish or anything, we're going to the hospital. Deal?"

I nodded, leaning into his embrace.

"Deal. Now, how about you pour us another glass of wine, and we can watch something mindless on TV?"

Adam kissed the top of my head and got up to refill our glasses. As he handed me mine, he asked, "So, how's the wedding planning coming along? Any new developments?"

I took a sip of my wine, considering how much to share. I'd been so focused on work lately that the wedding planning had taken a backseat. "Well, I finally managed to book the caterer. Remember the one we liked with the amazing reviews?

The one with the outrageous price tag?" I said, trying to keep the excitement out of my voice. I didn't want Adam to think I was overspending, even though I knew he'd never complain about the caterer's fee. He was too understanding, too supportive of my desire to have the perfect wedding.

Adam raised an eyebrow. "The one that costs more than my monthly salary? That one?"

I playfully swatted his arm. "Don't be dramatic. It's not that bad. Besides, it's our special day.

We deserve the best," I said, a hint of defensiveness creeping into my voice. I knew Adam was teasing, but I couldn't help feeling a little sensitive about the topic. I wanted our wedding to be perfect, a reflection of our love and commitment to each other. I didn't want to skimp on any details, no matter how extravagant they might seem.

Adam held up his hands in surrender. "Hey, I'm not complaining. If it means that much to you, then it means that much to me too. I trust your judgment, Sarah.

If you think this caterer is the best, then I'm sure they will be. I just want to make sure we're not breaking the bank, you know? We still have the honeymoon to plan, and I have my heart set on that cabin in the woods I was telling you about," Adam said, his eyes twinkling with excitement. He'd been raving about this cabin for weeks, claiming it was the perfect place for us to unplug and reconnect after the wedding.

I smiled, my earlier defensiveness melting away. "You're right. We do need to be mindful of our budget.

But hey, let's not worry about that tonight, okay? Tonight, we're just going to relax, enjoy our wine, and maybe even order some takeout. What do you say?" I suggested, nudging Adam playfully.

Adam grinned, his eyes crinkling at the corners. "That sounds like a perfect plan. What are you in the mood for? Thai? Italian? Or maybe we could try that new sushi place downtown?"

I wrinkled my nose at the mention of sushi. "Mmm, not really feeling raw fish tonight. How about we go with Thai?

I've been craving their pad see ew all day," I said, pulling out my phone to order our dinner. Adam nodded in agreement, his stomach rumbling audibly at the mention of his favorite dish.

"Sold. Make sure to get extra spring rolls, will you? I'm starving," Adam said, patting his flat stomach. I laughed, adding the extra order to our cart before hitting submit.

"Done. They said it'll be about thirty minutes. Just enough time for us to start a movie," I said, grabbing the remote and flipping through the streaming service's library.

Adam settled in next to me, his arm draped casually over my shoulders. I nestled against him, my body still feeling oddly sensitive and charged from the day's events. I tried to brush it off as exhaustion and the lingering effects of the bite, but there was something more to it, something I couldn't quite put my finger on.

As the opening credits of a cheesy action movie rolled, I couldn't help but feel a growing restlessness. I shifted in my seat, trying to get comfortable, but every movement seemed to send little jolts of electricity coursing through me.

I took a deep breath, trying to calm my racing heart, but it only served to fill my lungs with Adam's scent - warm, comforting, and oh-so-tempting. I felt a sudden, overwhelming urge to lean in, to press my lips to his neck, to taste his skin. I shook my head slightly, trying to clear my thoughts. What was wrong with me? I'd never felt this... this hungry, this desperate for him before.

Adam must have noticed my fidgeting because he glanced down at me, concern etched on his face. "Are you okay, Sarah?

You seem... restless," Adam said, his voice laced with concern. I could feel his eyes on me, studying me, trying to figure out what was going on behind my eyes.

I forced a smile, trying to put his mind at ease. "Yeah, I'm fine. Just... a lot on my mind, I guess. Work stuff," I lied, hating myself for it. I didn't want to worry him, not when there was nothing either of us could do about this strange, insatiable hunger inside me.

I took a deep breath, trying to rein in my spiraling emotions and focus on the movie playing on the screen. But every time Adam shifted next to me, his arm brushing against mine, I felt that hunger grow, like a beast awakening from a long slumber.

Adam seemed oblivious to my internal struggle, engrossed in the action unfolding on the screen. I watched him out of the corner of my eye, taking in the way his brow furrowed in concentration, the way his lips parted slightly when he was surprised.

He was so... human. So vulnerable. The thought sent a shiver down my spine, and I realized with a start that I was suddenly, acutely aware of every inch of my body. My skin felt too tight, too sensitive, like it was alive with a thousand tiny nerve endings, all crying out for touch, for release.

Adam must have felt my gaze because he turned to look at me, his eyes searching mine. "Sarah? Are you sure you're okay? You look... different," he said, his voice barely above a whisper. There was a hint of concern in his tone, but also something else.

Something that made my heart race and my breath catch in my throat. I saw it then, the flicker of desire in his eyes, mirroring my own. He was feeling it too, this strange, electric connection that seemed to hum between us like a live wire.

I swallowed hard, trying to find my voice. "I'm... I'm fine, Adam. Just... just tired, I guess," I said, turning my attention back to the TV. But the movie had lost its appeal, the sounds of explosions and gunfire suddenly too loud, too aggressive.

All I could focus on was the warmth of Adam's body pressed against mine, the rise and fall of his chest as he breathed. I could feel my heart pounding in my chest, my blood rushing through my veins like a wild river. I shifted again, trying to find some semblance of comfort, but it was no use. I was on fire, and I needed... something. Anything.

Adam's hand tightened on my shoulder, his thumb tracing small circles on my skin. "Sarah, talk to me. What's going on?" His voice was low, concerned, but there was an undercurrent of something else.

Something that sent a shiver down my spine and made my heart race even faster. I turned to look at him, our faces inches apart. His eyes searched mine, and I saw it again - that flicker of desire, reflected back at me like a mirror.

I licked my lips, suddenly aware of how dry my mouth was. "Adam, I... I don't know what's happening to me," I admitted, my voice barely above a whisper. "I feel... strange. Different."

Adam's gaze dropped to my lips, and I saw him swallow hard. "Different how?" he asked, his voice hoarse.

I took a deep breath, trying to find the words to explain the whirlwind of sensations coursing through me. I feel like I'm on fire. Every inch of my skin is sensitive, like it's alive with... with electricity. And I... I need..." I trailed off, unable to put into words the desperate, insatiable hunger gnawing at me.
