(Just a little warning. The following scene, though consensual, does make mention of hitting to cause pain and things of that nature. I don't think it is anything crazy but if that is something that could trigger you then skip this chapter.)

Hermione spent the day trying to get close to Lupin; this was not unusual, Hermione and Lupin got along well, and they often had great conversations and discussions about things that her friends were not particularly interested in. But this was different for two reasons, firstly she had a far different intention this time around and secondly Lupin was busy with his son Teddy a lot of the time. Tonks was pregnant again and having a difficult pregnancy, so Lupin was making sure to look after Teddy as often as possible. Seeing him look after his son and being a domesticated man made her very unsure about the bet and if she even wanted to try have sex with him. She wanted to win, that was certain, but she had no desire to ruin a marriage, especially one as good as Lupin and Tonks.

As the day progressed Lupin also seemed restless and withdrawn, the full moon was coming in a few days, so it was not unusual for him to feel under the weather, but it seemed a lot worse than usual. After dinner she was trying to ask him if he wanted dessert and she must have startled him a bit because he turned and almost growled at her. Tonks also noticed and took Teddy from him and whispered in his ear and he turned left the house. The rest of the evening passed without event, but Hermione was feeling hopeless in her chances to win the bet. After dessert was cleared and cleaned up many people retired to their tents. Hermione was supposed to go share a room with Ginny, but she was that Teddy was fussing and Tonks looked stressed as she walked to her tent in the yard.

Hermione ran over to catch up to her.
"Tonks," she called out, catching up and taking the baby bag from her arms. "Here let me help."
"Thank you so much," Tonks sighed. "I'm just trying to get him in a bath, so he can settle for bed."
They entered the tent and Hermione laid down the bag and lit the fire to warm up the tent.
"I am happy to help, I'll bathe him, and you can have a shower, that way you can both go to bed fresh."
Tonks looked like she could cry, "thank you so much Hermione, that would be great. I just need a second to breath and I will be much better."
"Don't worry about it. I am happy to help, and he is such a good baby."
Hermione grabbed the baby bath and sat it next to the fireplace, muttered a spell to fill it with warm water and grabbed a container full of baby bath supplies. Tonks had already undressed him and Hermione scooped him up and took him over to the bath.
"Go shower Tonks, I have him and I can always yell out if I need anything."
Tonks thanked her again and headed to the shower. Lupin was nowhere to be seen but Hermione couldn't focus on that, she had a baby to care for.

Hermione was correct when she said Teddy was a good baby, his grizzling stopped as soon as he entered the water and he was more than happy to sit there and play with his bath toys. Wizarding bath toys were nothing like muggle toys, he had little plastic looking fish and frogs that swam around in the water and little boats that tooted their horn and made slow circles in front of Teddy. His favourite was a bath bomb that made the water change colours from blue to red to green. He got so excited his little tuff of hair began changing colours too. Hermione laughed and washed his hair and body and played with him, laughing and smiling with him.
She heard Tonks approach and looked up to see her looking much calmer and content, smiling down at her son. Hermione took the towel from her hands and scooped Teddy out of the bath.
"I'll get him ready, don't worry. Just relax and I'll get him all finished up."
Tonks say in a rocking chair smiling at the Teddy while Hermione laid him on the bed to dry him and get him ready for bed.

"Thank you again Hermione, you're a lifesaver. Being pregnant has me exhausted all day. It was nice to just have a shower."
"Not a problem Tonks," Hermione smiled, "is Lupin alright? It's weird to not see him helping out."
"Yeah it's just two days out from the full moon so he's a little on edge."
Hermione nodded as moisturized Teddy's soft skin. "Must be bad to keep him away from you two."
"Usually it's not a problem, my pregnancy has just complicated things and being away from home has complicated things more."
Hermione nodded again, slipping Teddy into pyjamas and handing him to Tonks. "I'll just clean up the bath stuff and leave you to it. Sorry for the questions, I just wanted to make sure you are alright."
"No it's not a problem," Tonks replied, opening her robe so she could feed Teddy, "honestly, it's nice to have someone to talk to."
"Well I'm always happy to listen," Hermione replied, tidying up the bath area.
"Usually we have sex and that will provide him with some release," Tonks explained, "but because it is so close to the full moon he gets very rough. Usually that is fine by me, sometimes I even look forward to it. But when I'm pregnant I can't handle it and we wouldn't want anything to happen to the baby. But without the release he just gets more animalistic and I think it makes his transformations harder too. Because he hasn't had the relief he can't even sleep in the tent with us."

Hermione nodded, taking in this information and she finished tidying up. "So, he just has to deal with that until baby is born?"
Tonks shook her head, "No usually we hire someone to sleep with him. I know that seems weird, but I know it is complete carnal desire and it helps him. I honestly think it saved our marriage when I was pregnant with Teddy."
Hermione saw a flicker of hope. "So, you would be okay with him having sex with someone else tonight?"
Tonks nodded eagerly, "I wish we could sort that, we just don't feel comfortable bringing women to the Burrow and I can't just go around asking the single women here if they'll have rough sex with my husband?"
Hermione sat on the bed and smiled. "I think I can help you there Tonks."
"No, it's fine. We don't want help sneaking girls in. We're not worried about being caught we just don't feel comfortable."
Hermione let out a soft laugh. "No that's not what I'm talking about. I'll have sex with him. Hopefully that will make his transformation tomorrow a bit easier."

"No, I could never ask that of you," Tonks replied, "I wouldn't want to risk you getting hurt or upset or not wanting to be around us after or something like that."
"Tonks don't worry about that, I'm a big girl. I'll only do it if you are okay with it but I am more than happy to help."
"I don't know…" Tonks was hesitant.
"Tonks it will help you both. I am a big girl now, I know what I'm getting into. If all else fails we can all use a memory spell and forget it ever happened. Let me help you."
Hermione could tell that Tonks wanted to say yes but felt bad.
"Look you don't even have to say yes, I'm going to go do it. If you aren't okay with that tell me now and I will just go to bed, if you're okay with it then say nothing and sleep well."
She walked slowly out of the tent smiling to herself. She was so lucky, an hour ago she thought she had lost and now she was back in the game. Hopefully Lupin would agree as well.

As she stepped out of the tent there was a skip in her step, Tonks remained silent and she headed to the back of the yard. The Weasleys had created a soundproof shed in the back of the yard so Lupin had somewhere to transform without having to be embarrassed anyone would see or hear. The wolfsbane potion made him harmless at the full moon but it was still a loud and painful process and something Lupin was very self-conscious about. She assumed this would be where he was sleeping tonight seeing as he wasn't with Tonks.
She walked over to the shed and knocked. Lupin opened the door, "Tonks you know it's not safe to…" he stopped as he saw Hermione.
"Hello Remus," Hermione smiled. "Tonks told me about your little dilemma and I am here to help."
"How would you…?"
"How do you think? I already talked to Tonks. She has given permission."

"Come inside." Remus looked around, "let's not talk about this out here."
She entered and saw that the room had very little in it. A single chair, a double bed and a small set of bedside drawers were all that was there.
"Hermione, I don't think you understand what you are agreeing to. This close to the full moon sex becomes primal for me. You will need to keep your wand near to stop be if something goes too far because I won't be able to stop myself."
This should have scared her, but she felt desire tighten her abdomen and pool between her legs.
Remus I can protect myself. If I can't handle it I won't hold it against you." She pulled off her pants and shirt, kicking off her shoes, leaving her in a bra and panties. "I want this."
Lupin growled, "Hermione I can't stop myself if you do things like that."
She reached behind her and unclipped her bra and threw it aside. "Then don't."

That was all it took for Remus to be convinced, he stepped towards her to close the gap between them and pulled her close, kissing her deeply. His hands roamed through her hair and she felt him grab a tight handful and pulled her head back, so they could look each other in the eye.
"I'm going to fuck you so hard you feel it for days."
The way he spoke scared her in the best way, he kept her head pulled back and bit and kissed her throat while she gasped at the sensation.
He grabbed his shirt and tore it open, shrugging it off while kicking off his pants.
Her eyes opened wide at the sight of him, his body was littered in scars, some small and white some deep and still pink or purple but that's not what caught her eye. It was his huge cock. It was unlike anything she had ever seen before, she wasn't sure if it was a side effect of being a werewolf, but she suspected so because it was disproportionate to his slim, tall frame. He grabbed her hair and pulled her head down till she was on her knees in front of his cock. He glared down at her and she knew what he wanted but wondered if she could even fit it in her mouth.

She opened her mouth as wide as it would go, and he pushed his cock deep into her mouth, even with her throat relaxed she felt like it was barely going in past the head and she reached both hands up to stroke what she couldn't fit in her mouth.
He grabbed two handfuls of hair and used it to hold her head still while he fucked her skull. He was grunting and growling, and she had to really focus on breathing, but it felt so good to be used like this. She understood the warnings, one look at Lupin and she could tell he was in a primal state, he was not the gentle and kind professor that she knew. Tears were falling from the gagging, but she didn't want to stop, she loved being used like a toy.
He thrust deep, each thrust getting more erratic and desperate and she knew he was going to explode soon.
Sure enough he came with a yell deep in her throat. She tried to swallow it all but there was so much she couldn't help but have some dribble out onto her chin and breasts. He let go of her hair and pulled his dick out of her mouth, throwing her his ripped shirt to wipe herself.

She wiped the mess, aroused just knowing she was covered in his juices but worried that his ejaculation would equal the end of his primal state. She looked at him and knew her worried were in vain, he still had the dark look in his eyes that let her know he was still in his animalist state.
"Bed." He pointed, and she knew it was a command. He reached into the bedside table and pulled out a vibrator and a large dildo, throwing it at her. "Use it."
She assumed this primal state was causing the loss for words, but she didn't question it. He was soft after dropping that load in her mouth, but she knew she could change that soon.

She turned on the vibrator first, rubbing it over her clit at a low setting to get her warmed up to it before bumping the intensity up a bit and moaning as she let it pleasure her. As she moaned she reached for the dildo and slowly pushed it into her groaning as it opened her up. She looked at her and his breathing was sharp and shallow, and she could already see him beginning to get hard again.
She got onto her knees and positioned herself over the thick dildo and held it still while lowering herself on it and feeling herself be split open again. She lowered herself on it again and again, holding the vibrator onto her clit with her other hand.
"Oh God this feels good," Hermione gasped, "Fuck I'm going to cum like this."
Lupin groaned, he was not stroking his cock, getting it to full mast.
Seeing his hands wrapped around his cock brought her to the edge and she levelled the vibration up once more before screaming her release.
"FUCK I'M CUMMING. MERLIN THIS FEELS GOOD."

Lupin reached over and pulled the dildo out of her and out of her hand. She turned off the vibrator just before he tossed that aside as well.
He wordlessly pushed her onto her stomach and lifted her ass up to him, for a second, she felt him positioned behind her, then he pushed his cock inside her and slammed it all the way inside her.
"LUPIN," she screamed his name in a mix of pain and pleasure, but it was like he couldn't hear her. He grabbed her hips and pulled her onto him while thrusting into her and it felt deeper than possible. It was rough, and it hurt but she did not want him to stop. She moaned and screamed with every thrust and she knew she was going to cum like this, she loved how slutty she felt.
After a while he put a hand in her hair and grabbed a fistful again, forcing her head into the bed.
He held it tight and she had to focus on her breathing again but with her head down and her ass up like this he was hitting a new spot that was making her scream even louder than before. He was still using his free hand to pull her onto him and it was so deep she knew it was only going to last a little longer before she came over his cock.
Sure enough, she came screaming his name into the mattress. She wondered if he'd even notice but he pulled out, so she guessed he did and pulled her up by her hair as she gasped for air, still moaning from her release.

He got off the bed and pulled her off with him, dragging her over to the chair. He let go of her hair and sat down before pulling her close to him. It was a single person couch so it had armrests and he lifted her up with shocking strength, letting her legs dangle over the armrests and sinking her down onto him, she moaned loudly at the sudden penetration, the pain was still present but it felt more like an ache and if she was honest she didn't know if that was from his size or from her desire for him.
He grabbed her waist and pulled her down onto his cock, relentless just as he had been on the bed. He caught a nipple in his mouth as she was bouncing on his cock and bit it and roughly sucked at it. The pain made her gasp as he bit and pulled at a nipple before swapping to the other nipple and doing the same. The pain was bringing tears to her eyes but not because she wanted him to stop but because she desperately wanted to cum and all the sensations were pushing her to the edge. She reached between their bodies and rubbed at her clit desperately, he released her nipple to look down at her pussy being stretched to the edge and her fingers rubbing at her clit. He groaned and seeing his eyes locked on her pussy was the final thing to push her over the edge. She moaned and felt a couple tears stream down her face, so relieved to finally get the release she needed.

Hermione had barely finished, and he was pulling her off him, and dragging her to the bed again. He bent her over the bed, she was grateful for this as she needed some time to regain her strength. He grabbed a handful of her ass and groaned before raising a hand and spanking it against her ass.
"Fuck yes."
Though she was tired she could feel her orgasm building already. He continued to slap her ass, swapping cheeks and she knew it was going to leave marks for days. Just like everything else they had done tonight there was certainly pain but it was only making her want more.
"Remus please. I want to cum again," she begged.
But he ignored her and continued to slap her ass. He pushed her legs open and put a soft backhand slap against her pussy.
"Oh, fuck yes," Hermione gasped.
He slapped it a few more times causing her to bite at the blanket. It was painful and almost more than she could handle but she did not want him to stop.

He rolled her over and moved her up the bed, pushing her knees open and getting between her legs.
He grabbed her throat roughly and pushed roughly into her at the same time. She moaned but it came out strained because of his hand wrapped around her throat. He thrust deep and hard into her, if he wasn't holding her down by the throat she would have been pushed up the bed. He raised his spare hand and slapped her face, making her cheeks sting and her gasp.
He slapped her a few more times and tightened the grip on her throat to where she could see stars. She should have been worried, but it made her cum, almost silently because of the hand on her throat but she lifted her hips desperately, so she could get him as deep as possible while she came.

He removed his hands from her face and throat and grabbed the back of her knees, pushing them up to her head and slamming into her rough and hard.
She could tell that he was close to cumming because his eyes were shut, and he was slamming into her harder and harder with each thrust.
"Remus please," she rasped, her throat raw from the blowjob and now the choking, "cum in my pussy."
Perhaps he heard her this time or maybe it was a coincidence, but he thrust a few more times before slamming deep into her and letting out a moan that sounded like a howl.
The last thrust pushed Hermione over the edge as well and she screamed, though it was muted from the state of her throat.

He remained buried inside her for a few seconds before pulling out and moaning at the sight of him cum leaking out of her stretched hole. He walked over to his pants and pulled them up before reaching into his side table for a new shirt.
She sat up and could already tell the sex had done its job, he was looking embarrassed and not meeting her eye.
"Hermione I'm sorry…"
"Don't be." Hermione interrupted. She could see him cringe at the rasping of her voice, but she continued as she did a quick freshening spell and threw on her clothes. "I loved every second and we never need to talk about this again. I am not upset or hurt or anything of the sort."
Lupin looked doubtful and opened his mouth to say something but couldn't find the words.
"Remus I am truly happy. I'm going to head inside now. Just go enjoy sleeping next to your wife."
She smiled at him and rushed out the door towards the house.

She headed up the stairs to Ginny's room, trying to sneak in and get into bed before anyone noticed. But as soon as she shut the door behind her she heard her friends voice.
"Lumos."
Ginny was glaring at Hermione and she stood, frozen with shock.
"Where have you and Luna been?" she asked angrily. "Luna hasn't come up either and I couldn't find you anywhere."
"Ginny I…" Hermione rasped.
"Merlin what is wrong with your voice," Ginny gasped. She looked Hermione up and down. "Omg you've had sex!"
'No of course not!" Hermione hoarsely denied, "I've just been in the bathroom sick."
Ginny surprised her by laughing. "Hermione I can see the handprint on your face and the finger marks on your throat. Don't lie to your friends!"

Hermione was relieved at the positive reaction and laughed at the poor lie.
"Please tell me it wasn't my brother."
"No, it wasn't!" Hermione assured.
"Thank God." Ginny laughed. "I wouldn't be able to look at them again."
As they laughed the door opened again and Luna stumbled in, obviously stunned to see the two girls awake. Though the signs were less obvious than Hermione it was still clear that she had been fucked.
"What the hell? You as well?" Ginny gasped. "This isn't a coincidence. You two have been weird as for weeks now. What is happening."
Luna and Hermione looked at each other, neither wanting to say anything.
"Tell me now or I'll start asking people." Ginny was getting mad again.
"Okay," Luna replied, looking at Hermione who nodded. "We'll explain. But don't judge."
