Word: Beget

...

"Derek! Get your lazy butt out of bed and help me down here!"

Stiles doubts that his yelling has even stirred Derek, especially since the noise from their two and four year old terrors hasn't woken him yet. Sighing, Stiles leaves the girls to their tantrums and stomps upstairs. He flings the bedroom door open, glaring in the general direction of the bed. The room is too dark for him to see anything, so he flicks the light switch, and then proceeds to glare at Derek even more. The noise of the tantrums filter into the room, and Derek sits up quickly, alert and thinking of danger. (Stiles feels a bit bad about that, but he's been dealing with the girls for the last three hours, and he knew that they shouldn't have soundproofed their room, dammit.)

"What's wrong?" Derek asks, eyes glowing blue and claws extended, the wolf ready to attack and defend his family and pack.

"Your daughters are attempting to redecorate the living room with crayons and their claws. I can't get either of them to settle; I swear my Dad's cursed them to be just like me when I was younger, and I don't know what I did to deserve this fresh hell," Stiles mutters, folding his arms over his chest.

"My daughters? I thought they were all yours?" Derek replies, grinning slightly as his wolf slips away.

He stretches, arms rising above his head, and Stiles forgets his retort as his husband's abs are revealed, his biceps flexing with the stretch, and he remembers placing several bites on that stomach just last night. Then a particularly loud screech comes from downstairs, and Stiles' glower returns in full force.

"They're yours when they're being little monsters," he mutters. "You beget the monsters; the smart-ass gene's mine."

"Right; I'll remember that the next time they try to swindle their way out of something. Or into it," Derek mutters, shaking his head and getting out of bed.

"Come on, before they destroy the couch again," Stiles says, grabbing Derek's hand and tugging him downstairs.

"Holly, Missy! Put the crayons down right now!" Derek demands, and the assbutt doesn't even have to wolf out on them for their daughters to do as he says immediately, their bottom lips wavering.

"We're drawing, Daddy!" Missy says, glancing over to the bright moon she's drawn on the wall, above the small forest Holly's depicted.

"We just wanted to bring the forest in here, 'cause you and Papa both like the full moon, and we only see it once a month," Holly adds, eyes wide as she looks up at them.

They both know they're being played, that Holly's most likely thought the entire argument through - Stiles is definitely the one to blame for that, Derek thinks to himself - and while they know that, it doesn't stop them falling for it. Stiles caves first, cursing himself and his inability to resist puppy eyes, and pulls Holly and Missy in for a hug.

"You're both cleaning the wall. Then we'll get some paper for you to draw on properly, okay?" Stiles suggests, both girls nodding against his chest.

"Okay, Papa," Holly says, sounding demure enough.

Derek sighs and kneels beside his family, pulling all three of them on to his lap. Stiles moves his head to kiss Derek, grinning when Holly squeals something about them being so gross.

"Yep!" Stiles admits happily, kissing Holly all over her face until she's squealing in laughter in his arms.

Missy squirms until Derek picks her up, tucking her under his arm as she giggles in delight. He grins and heads to the laundry to get a bucket of warm water, soap, and cleaning cloths.

They spend most of the morning cleaning the walls of Holly and Missy's handiwork, and go outside to empty the buckets in the backyard. Stiles and Holly have obviously been conspiring together while Derek's been singing along to the radio's cheesy 80's songs and making Missy laugh. The two traitors initiate a water fight by pouring a bucket of water on Derek's head. He's left there spluttering for half a minute before he chases after them with his own bucket, Missy toddling after them armed with a wet cloth and roaring.

Stiles just laughs when he's pounced on, and pulls Derek to the ground with Holly and Missy jumping on the pile a moment later. Derek noses against Stiles' neck, breathing in his scent, and Holly curls up against their entwined legs, Missy moving to squirm in between their arms. Stiles presses a kiss to the top of her head, and they all fall asleep on the grass, sun shining down on them and drying their wet clothes.

It's totally worth the grass rash Stiles gets on his legs afterwards.
