A prompt fill from a tumblr request where Jennifer is pregnant with quadruplets.

This story is Derek x Jennifer and Cora x Stiles.


'Now,' Melissa took Jennifer's hand and squeezed as she sat on the stool by the side of the bed. On the other side Derek stood motionless like a statue, his leather jacket over his shoulders, fingers resting on Jennifer's arm. 'This is going to be cold.'

'O-okay,' Jennifer smiled a little and looked at Derek. His face was blank as he looked back at her and Melissa wanted to beat him, Jennifer was obviously excited but he was his usual self, cold, stoic. She couldn't imagine any passion in him. Sex must have been awkward.

'Can't you warm it up for her?' Derek asked.

'No, I can't. Her skin will heat it,' Melissa said.

'It's okay Derek,' Jennifer took his hand in hers and they shared that blank look again. Melissa wondered how Scott put up with him so much.

'Okay, and it's going to hurt. I'll be pressing into your body a little.' Melissa said glancing up at Derek just in time to cut him off. He narrowed his eyes slightly and Melissa made a mental note to pull Jennifer aside and make sure their relationship was completely consensual. Melissa remembered those days with a shudder.

'Okay,' Jennifer squeezed Derek's fingers and glanced up at him. Derek cupped a hand around her head, offering a small curve of the lips. Melissa wanted to ask him if he called that a smile.

The screen was blank for a minute as Melissa got her bearings. Jennifer watched hopefully, Derek's eyes flicking between the wand and the monitor.

At first the baby was easily found but then Melissa noticed something else, something strange. 'Uh,' she stepped back taking the wand away and squeezing Jennifer's shoulder. 'I just need to get someone just two seconds!'

'Melissa?' Jennifer asked with wide eyes.

Melissa shot her a smile as she left the room, finding a doctor almost immediately. 'I need your help.'

The room was quiet when she got back but Derek looked furious and Jennifer looked upset. 'Hi, I'm doctor Kane; I'm just going to have a look at your little miracle.' Jennifer nodded eyes wide and almost wet. 'There's nothing wrong.' He said touching her hand.

'Okay,' Jennifer didn't sound convinced.

'You're right Melissa,' doctor Kane shot her a warm smile. 'Honours?'

'Well, this is the baby here, little head, and this is baby's sibling,' Melissa looked over at Jennifer who was gaping.

'Twins?' Jennifer asked as Derek stared at the screen, his face blank.

'And we have another baby here and last but not least...' Melissa said gently.

'Four?' Derek shot a look at Melissa. She nodded and then lost her breath when the biggest smile split his face. 'You hear that?' Derek bent and his forehead fessed into Jennifer's, their noses touching as they smiled at each other. 'You got me four?'

'I didn't plan it this way,' Jennifer blushed then looked back at the screen. 'Last night we decided we wanted four kids,' Jennifer bit her lip.

'Four?' Derek gaped again with a look of awe on his face.

Melissa giggled a little at his expression. 'I'll leave you three,' doctor Kane touched her arm and left the room.

'Four?' Derek asked again running his fingertips over her skin, through the gel used for the wand.

'Can you make each one out?' Melissa asked as Derek lifted his head to look again.

'Show us,' Jennifer almost pleaded as Derek watched closely, both the movement over the swell of her abdomen and the screen, memorising the position of each child.

'It probably won't go the full forty weeks,' Melissa admitted.

'It won't, Jennifer will be pregnant for nine moons.' Derek explained. Melissa cocked an eyebrow at him and he returned it with a slight glance of his own hostility.

'Expert are we?' Melissa snapped.

'My mother was pregnant when I was a child, I know this. Jennifer conceived on the last moon in October. That was the first of nine moons. We're already on our third moon, tonight actually. There will only be six moons left.' Derek explained to Melissa. By the looks of things Jennifer already knew what he was talking about; her eyes were trained on the screen. On her babies.

'How do you know the date of conception that they're going to be werewolves? They may not be.' Jennifer said.

'Traditionally one in four children born to one werewolf and one human parent is human themselves.' Derek explained gently, his fingers making a pattern around Jennifer's navel. 'Werewolf couples tend to be fertile at one time of the month.'

'Jennifer's not a werewolf.' Melissa raised her chin.

'Not yet, but her body cycle changes and when she was fertile I could scent it on her skin. It's around the time of the month that the other mate wants to mount funnily enough.' Derek explained.

'What about gay and lesbian couples?' Melissa cocked her head to the side.

'The less dominant partner will produce a hormone that attracts their lover, making them much more appealing.' Derek said his eyes flicking to the screen. Melissa looked up, almost overwhelmed with the feeling of pride in the room as Derek gazed at the babies.

'Does Scott know all this?' Melissa asked quietly.

'No,' Derek said.

'Well don't you think you should tell him then you idiot?' Melissa snapped. Derek reeled back slightly but Jennifer's cool fingers looped Melissa's wrist.

'Scott didn't want to know the pregnancy stuff, but in their junior year I was there when Derek sat all the kids down and explained about the most fertile times of the month. Cora and Stiles had just started dating.' Jennifer responded, but her eyes were still stuck on the screen. Melissa nodded in understanding.

'Safe sex with werewolves is more than just condoms, but getting pregnant any time that's not close to the full moon isn't easy for even the most determined of teenagers.' Derek said.

'Okay,' Melissa relaxed her wrist.

'No, keep talking; let me look a little longer.' Jennifer pleaded. Melissa smiled at her and Derek crouched to kiss her cheek as they watched the screen together.

Ten minutes passed, and finally Derek convinced Jennifer to allow Melissa to tidy up. She listened to their plans for the evening ahead, their intentions to get dinner. Melissa's stomach rumbled loudly at the thought of food. 'Okay then,' Melissa smiled.

'Can I talk to you?' Jennifer asked.

'I'll wait outside,' Derek said and Melissa watched him go.

'He's not a monster you know,' Jennifer said softly once the door was closed.

'I-'

'I know you don't like him. He's not hurting me or coercing me in any way. I love him and I know he loves me.' Jennifer said.

'He's loose cannon. I mean, he broke Isaac's arm.' Melissa said.

'I know all Derek's sins, some of them you couldn't even imagine. I know his reason for every single thing he's ever done, I know why he is the way he is. I know he wouldn't hurt me, or the kids.' Jennifer said.

'He broke. Isaac's. Arm.' Melissa said.

'When Derek was seven he accidentally clawed his cousin who was fifteen, tore her skin. His punishment, to have his wrist broken. That wasn't the first time. It wasn't abuse; it was a punishment he recovered from. Derek knows now the difference between werewolf children and human ones.' Jennifer explained softly.

'What if he breaks one of these little ones?' Melissa asked.

'He won't. We've discussed alternative punishments. We planned a baby, we got four but we planned this, we know what to expect from each other. I know he looks intimidating, and frightening, but he's a softie, and he can't wait to be a father.' Jennifer said proudly.

'You know what you're doing?' Melissa suggested.

'I know what I'm doing. I could do with a friend,' Jennifer smiled hopefully. Melissa smiled back at her. 'Come for dinner with us tonight.'

'I couldn't-'

'Don't be silly, of course you can. I insist, I want to celebrate!' Jennifer tugged her hand and Melissa felt helpless. She'd already changed from her scrubs.

They went outside to the hallway to where Derek was gazing at ultrasound pictures printed not twenty minutes ago and Melissa figured that perhaps things would be alright for the Hale kids.

Derek slid his arm along the back of Jennifer's chair, gazing at the side of her head. She was wearing little diamond earrings he'd bought her after their first full month together without blood having been spilt She called them her blood diamonds, and wore them for luck, but Jennifer was foolish because Derek was the lucky one.

She laughed, throwing her head back a little, her hair tumbling down her back over his bare forearm. She turned and caught him watching her. 'Stop being creepy,' she slapped his chest.

Derek smiled at her and turned to Melissa. 'Sorry, I tuned out; I'm just trying to get my head around the fact that there are five people in the seat beside me.'

Melissa let out a surprised laugh, and sat back in her seat as Jennifer reached for Derek's hand. 'Shall we get dessert?' She asked.

'I don't want any, you two go ahead.' Derek said. They chose a slice to share, and laughed when it arrived.

'Wow, okay,' Melissa shuffled toward them a little and they made plans to meet once a week, talking about the book they read recently. Derek tuned it all out until they walked Melissa to her car. She was a lot less hostile towards him but her eyes still locked onto him.

It was when they were back home that it sank in. Derek could picture the place in a few years, toys and shoes lying in piles around the rooms, little heartbeats beating steadily in the rooms upstairs as their parents try to get over hectic days run off their feet.

'Hey,' Derek caught her hand, tugging her towards him, pecking her lips. 'I think we should go to bed, and get some rest because pretty soon we're going to be run off our feet.'

'I like it but I don't want to sleep,' Jennifer said softly. Derek chuckled and grabbed her around the waist, pulling her against him before leading her upstairs.
