House: Gryffindor

 My boyfriend, Remus Lupin, was an enigma. On the surface he seemed the like the perfect student, a role model, so kind and mature when in reality he was probably the most troublesome out of the four Marauders but he knew how to be discreet. Not only that but he could be temperamental, clingy, sensitive and over-protective. He was still my boyfriend though and I loved him dearly, even if sometimes his emotions got the better of him.

There was one thing that I definitely wasn't prepared for when I accepted his confession, and that was just how sexual he was. It was often that he had me pinned down on his bed, naked, and he was even able to go multiple rounds. By the end I was often covered in sweat, panting breathlessly underneath him as he'd then suddenly turn into a sweet cuddle-monster, moving us around on his bed and pulling me in close.

I was currently sat on the sofa in the Gryffindor common room, staring at the dancing flames in the fireplace. Most people were outside enjoying the sun, my boyfriend and the rest of the Marauders included, however I was sat inside thinking about last night...

- Flashback -

"Mmph- Remus, slow down," I murmured as he dragged me up the boys dormitory stairs to his shared bedroom. He wasn't listening and continued to bite at my neck undoubtedly leaving hickies, something I wasn't particularly keen on him doing. We hadn't even gotten to the privacy of his room yet and he was already pulling my clothes off - thankfully no one was lingering on the stairs.

I slipped from his grasp, running up the stairs, not wanting to have any more of my skin being shown where it could be seen by other people. He slipped into the room and shut the door, but not before slipping a sock on the door handle - a 'do not disturb' sign that the guys used whenever one of them was getting laid.

Soon Remus was back on me, touching me roughly and ripping the clothes from my skin without even letting me touch his. I felt like I was prey and he was the predator, particularly when he pushed me down onto his bed. I shivered a little under his fierce gaze, and suddenly he had his shirt ripped open, his shoes kicked off and he was climbing over me, biting at my skin as he went. "Remus! That hurts!"

"Hmph, sorry," he growled. There was dominance radiating off of him, especially when he held both of my wrists in one hand and had his other massaging my breast. His mouth sucked at my nipple on the breast he wasn't massaging, and my legs twitched underneath him as pleasure pooled in my underwear, the only piece of clothing he had left me in.

His hands were all over me, apparently unsure on where to touch. I tried to get him to slow down but every time I said something, he wouldn't listen. It was as though he was in his own little bubble, something having taken ahold of his mind and clouding it with lust. "Kneel on the floor," he said in a demanding tone I didn't dare ignore. I did as was told and watched as he stripped off his trousers, them landing on the floor and the belt making a loud clattering sound. He pulled down his boxers as well, revealing his member and before I had a chance to say or do anything, he was pushing it in my mouth.

He took ahold of the back of my head, not letting go whilst moving his hips back and forth. He was thrusting deep into my mouth, further than he had gone before. I was trying my best not to choke, and tried to place my hands on his waist to slow him down but it was futile; I had never seen him act such a way. I knew he could get quite surprisingly sexual but he'd never been this forceful before.

I heard him grunt above me as he began to thrust faster, abusing my throat. "There's my good little bitch," he growled in a deep voice, my eyes widening at his tone and choice of words. Due to his rough thrusting, tears came to my eyes and I was caught off-guard when I felt him release into my mouth. "Swallow it," he demanded as he pulled out, his member still erect. I did as was told, shivering a little at the taste before looking back up at him.

There was a strange gleam in his eyes and suddenly he pulled me up and threw me on his bed. He ripped off his shirt, the both of us now being completely naked before he grabbed his Gryffindor tie and bound my wrists together. "R-Remus- what are you doing?"

"Shut up bitch," he growled and again I was shocked by his words. He clambered over me and took my ankles in his hands, folding me in half. He lined his member up with my core and without even getting me prepared, he thrusted himself in.

I cried out and arched my back, fighting against my restraints but with no avail. Thankfully he didn't move straight away, and instead waited for me to give him the go ahead which took me a few moments but as soon as I did, he couldn't be contained.

His pounding into me was relentless, so much so that I barely had time to catch my breath. The bed was creaking, the headboard hitting the wall. I clung onto him desperately, trying to relieve some of the intensity but it was impossible. I was crying out desperately, moaning his name on repeat. He was thrusting deeper and more powerfully than he ever had before, and there was a somewhat angry gleam in his eyes that seemed lust-fuelled.

I ran my hand through his hair, pulling on it a little due to his forcefulness but this action only spurred him on. It felt good, really good, and I felt myself etching closer and closer to cumming. "W-wait, Remus- s-slow down, I'm gonna cum-,"

"If you think I'm gonna stop then you've got another thing coming," he growled directly in my ear before latching his lips back onto my neck. I let out a yelp, desperately trying to break free of my restraints but it was futile, he had tied them too tight.

"Remus please untie me," I tried to breath but all that came out were murmurs. He ignored my request and instead pulled out, making me whine at the loss of contact due to the fact I was so close to releasing. I knew he was a surprisingly sexual person but he wasn't usually this selfish.

"Turn around. Get on all fours," he demanded, as though daring me to disobey him. I didn't want to find out what would happen if I did disobey him however, so I turned into doggy style and was shocked when I felt his palm slap my bum. "Good girl," he growled maliciously. I looked back at him to see him staring at my body as though it was some kind of new and exciting toy for him. I bit my lip hard when he thrusted back into me, the sound of skin-slapping filling the room as well as the familiar creaking of the bed. "You're my mate, do you understand?" He growled maliciously and I furrowed my eyebrows, wondering what he meant.

"R-Remus what- ah! W-what do you mean- nngh," I moaned, having to bury my head in the pillows to prevent me from moaning too loudly.

"Hey, don't cover those beautiful moans, let everyone know who's bitch you are!" He shouted, slamming into me even harder.

"Remus!" I cried out, throwing my head back whilst tears of pleasure came to my eyes. He took a fistful of my hair and pulled me backwards, leaning over me until my back was up against his torso.

"I'm gonna fill you with my pups, you understand?" He growled and my heart skipped a beat, my eyes widening.

"W-what-,"

"You're gonna get pregnant with my pups!" He shouted, his eyes scrunched closed. I thought, or rather hoped that he was just trying to talk dirty but he gave no sign that he was going to pull out, and that's when I panicked.

I too felt close to cumming, but he wasn't wearing protection so couldn't release inside of me. "Wait Remus, slow down!" I tried to say but the intensity of his thrusts and my upcoming orgasm was interrupting my speech, leaving me only capable of moaning. My mind was whirling as I desperately tried to tell him not to release inside of me, but it was too late. My back arched as I felt my orgasm hit, and I couldn't help but let out a loud cry, it quite possibly being the most intense I had felt.

Remus however was still going, sending me into a pit of overstimulation. He had a strong hold on my hips, keeping them raised whilst he thrusted into my womanhood roughly, refusing to let up. My chest collapsed on the bed as he abused my raw pussy, actually growling under his breath. There was fire in his eyes as he kept on mumbling about filling me with his 'pups', and every time I attempted to speak I found the wind knocked out of me from his powerful thrusts. My mind was going blank until he finally let out a deep groan and I felt him cum inside of me. My eyes widened, realising what he had just done.

I looked back at him quickly, surprised to see that he didn't regret releasing inside. It seemed as though he didn't even notice as he stared at my tired form, then collapsing beside me. He shifted slightly, pulling the duvet out from under us and laying it on top, not even bothering to go to his en-suite and cleaning up. I was surprised at him, as he had never acted this way before and it was making me nervous. Without saying anything he simply fell asleep, and all I could do was stare at him in shock.

Finally I came to my senses and quickly got dressed as soon as I had the energy, creeping out of the room and back to my own. I cleaned up as soon as I was there, making a mental note that I needed to see Madam Pomfrey as soon as I woke up, hoping she had some form of emergency contraceptives I could take. I also had no idea how to act around Remus tomorrow - was he just going to act like what just happened between us this evening was normal? Either way I needed to be stern, and voice the fact that him releasing inside of me without protection was not okay.

- Flashback Over -

I had of course been to see Madam Pomfrey as early as I could to explain that I had ended up having unprotected sex, and she immediately issued me a pill which she told me had a one-hundred percent effectiveness rate. I remember sighing in relief, but I was irritated with my boyfriend for thinking he could get away with such a thing. I hadn't seen him since this morning however, but that gave me time to figure out what I was going to say to him.

Just then the portrait hole opened and in walked my best friend Sirius Black. Us both coming from pureblood backgrounds, particularly families that believed in the dark arts we both understood each other well. We got on perfectly and as soon as he saw me he knew something was wrong. "(y/n), what's wrong?" He asked cautiously, approaching me.

"Is Remus with you?" I asked sceptically before telling him.

"No, why? Has he done something to hurt you?" Sirius asked quickly. He was like an older brother to me, so he was naturally protective.

"No, no it's just... last night when you James and Peter were out causing trouble, we made use of an empty dorm. He seemed somewhat odd though... like he was angry about something and he... said some things..." I spoke nervously and Sirius furrowed his eyebrows, hinting at me to continue. "He said 'I'm gonna fill you with my pups'..." Sirius' eyes widened dramatically before he suddenly burst out laughing. "Sirius I'm being serious! He could've gotten me pregnant!" As soon as I said this he stopped laughing.

"Wait he actually... y'know, inside?!" Sirius exclaimed and I nodded. "That bastard!"

"I at first thought he was just trying to talk dirty but he didn't show any signs of pulling out. He also kept on calling me his bitch, that he was going to mate with me. I panicked and tried to stop him but he pinned me down. He kept on growling as well, like properly growling. It was a little frightening actually..."

Sirius apparently didn't know what to say. He sat besides me, shocked and speechless. He was trying to read my face for any sign of a joke but realised that I was telling the complete truth. "Alright, try not to dwell on it (y/n), maybe he just got a little carried away. He might explain to you later why he said those things," Sirius seemed somewhat confident which confused me slightly.

"O-okay..." I wasn't really sure what else to say.

"I gotta go (y/n), but I'll see you later tonight okay?" He said, standing up. I nodded and watched him go, my thoughts wandering back to my boyfriend.

- Remus' POV -

Sat in the library I flicked through a book although I wasn't actually reading it. Last nights events swirled around in my brain, embarrassment swallowing me whole. I couldn't quite believe I had actually said those things but with the full moon tonight I felt as though my werewolf self had taken control of me. She didn't know what I was so probably thought I was crazy for saying what I said.

"So, you want her to have your 'pups' do you?" Sirius suddenly said, making me stiffen up. Thankfully there was no one in the vicinity as I shot my head up to look at one of my best friends. He was smirking and had one eyebrow raised.

"What do you want Padfoot?" I was on a short fuse, especially due to the fact it was a full moon this evening.

"For the millionth time Moony, you have to tell her. She'll understand, and it'll help her understand why you got so crazy last night," he said and I felt my cheeks heat up.

"So she told you?"

"Everything."

"Pfft," I scoffed. "She won't understand-,"

"Of course she will Moony! Do you not trust her-,"

"Of course I trust her!"

"Then you need to clear up last nights mess, she was terrified she was pregnant," Sirius said and I sighed. "Listen, you may not of dreamt of breaking the news to her this way but I think it's best you tell her now to clear the air."

I knew he was right but I didn't want to admit it. (y/n) deserved to know the truth, especially after last night. I buried my head in my hands wishing I had told her about it before, or at least wishing I didn't have to tell her in such circumstances. "Where is she?" I asked somewhat nervously.

"Common room," Sirius said simply. I nodded and packed my things away before heading there, trying to think of ways I could tell her. When I walked through the portrait hole I saw my girlfriend sitting there, staring at the fire. It took her a moment to look up but when she spotted me she stood abruptly, then fiddling with the ends of her top.

"H-hey," she said awkwardly, avoiding eye contact with me.

"(y/n) there's something I need to tell you," I said quickly, reaching out and taking her hand. I dragged her upstairs towards my dorm room, knowing that it'll be the best chance we'll have of true privacy.

When we were both inside I sat her down on my bed, me crouching before her and looking her directly in her eyes. "(y/n), I'm really sorry about last night. I was cruel, unfair and I probably scared you... there is a reason I was acting like that, though..." I started carefully.

"A reason? What do you mean?" She tilted her head out of curiosity. I sucked in a deep breath before finally saying what she needed to know.

"I'm a werewolf, (y/n)."

There was silence in the room and I saw her eyes wide with shock, clearly not expecting such a fact. I needed her to say something, anything, and I watched her facial features nervously in an effort to try and read what was going through her mind.

"Wow... it's fair to say I wasn't expecting that," she lightly chuckled. "H-how long?"

"Since I was four, so I'm pretty used to it now," I shrugged nonchalantly but her mouth was agape.

"Y-you we're four?!"

"Yeah, a werewolf named Greyback had a run in with my old man so decided to pay him back by biting me," I said bitterly.

"Oh my god," she whispered, still trying to digest this information.

"Sometimes werewolf tendencies interfere with my real life... like last night when I said those things," I mumbled, feeling incredibly embarrassed. Her eyes widened with realisation. "I'm sorry (y/n), really I am, I never meant to try and get you pregnant and I never meant to say those things, it's just tonight's a full moon and I'm getting to that age where it's beginning to affect me sexually..."

"Remus, thank you for telling me," she said sweetly, cupping my cheek.

"It hasn't... hasn't made you think differently about me, has it?" I asked nervously and she chuckled.

"Of course it hasn't! It's actually beginning to make sense for a lot of things... I assume that's where your scars come from?" She asked, tracing her finger along the scar across my nose and I nodded. "So should I expect this dominant sexual beast every month?"

"No! I mean... last night was the first time it happened... that's kind of why I wanted to clear the air, plus we've been together for a while so I thought you should know the truth about the guy you're dating," I said and she laughed. "So you don't care that I'm a monster?"

"A monster? Remus you are many things but a monster is not one of them," she laughed making my cheeks go red. "Of course I don't care if you're a werewolf because you're still you. Would it be alright to ask you to tell me more about being a werewolf?" She asked sweetly and I couldn't help but smile.

"Of course," I said, pulling her in for a hug first before the pair of us laid on my bed, me filling her in on everything she needed to know. I told her about the other guys being animagi, her now understanding our nicknames. She was desperate to help out in anyway she could, but I told her I didn't want her coming near me in my werewolf form in case I hurt her. She seemed to understand, but she surprised me when she insisted on becoming an animagus to help me. "You do know it's illegal without registration, right?"

"So? If James, Sirius and Peter can get away with it, then I'm sure I can," she said proudly making me chuckle.

"I love you (y/n)," I whispered and she looked up at me with a smile on her face.

"I love you too. Now, what do you think my animagus will be?"
