A/n: At last, here's trystrike's idea, and, I think, the last of the suggestions in general. I suppose you could read it for romance if you want, but nothing of that nature actually happens...
Still: enjoy!

'Do we have to?'

'Yes you have to. I'm too busy, and you said you would!'

Toothless grumbled irritably. He honestly couldn't remember agreeing to babysit all of his friends' children, but it was somehow unsurprising that he ended up getting roped into such a task. 'Fine.' he relented, turning to the hyperactive hatchlings he'd be spending the next few hours trapped with. 'But they'd better behave.'

'I'm sure they will,' Hiccup laughed at his partner's misfortune, 'You're the alpha, remember?'

Toothless sighed. 'And how come you get out of it?' he asked accusingly.

'I'm spending some time with Astrid. I've heard it's a thing most normal couples do.' Hiccup teased, leaving the room and closing the door behind him.

'Just great.' Toothless moaned, turning back to the young dragons.

'Toothless!' they yelled excitedly.

The alpha dragon sighed.

'Help!'

'Toothless? What -'

'No time. Just help!' Toothless yelled, running past Stormfly. The nadder frowned; the last she'd seen of Toothless, he'd been complaining about some baby dragons he had to look after - one of whom was actually hers. What was he doing running around the village?

'Toothless!' Her answer came in the form of four dragons, all running after the poor night fury. They seemed ecstatic to be in his presence, and with good reason; Toothless was a hero among dragons, on Berk and beyond, as the one who'd helped release them all from the Green Death's control.

Stormfly stepped out in front of the smaller dragons to stop them. 'Okay, calm down.' she instructed, doing her best to not get them any more excited.

'Hey mum!' Sleekscales called out, grinning wildly. 'We're playing with Toothless!'

'I can see that,' Stormfly laughed. 'So, how about we all go inside to play?'

'But then our riders won't be able to come along!'

Riders? Fireworm's concerned comment confused Stormfly slightly. Dragons usually didn't start training until they could properly fly and carry humans, and none of the four in front of her could do that quite yet.

'Their friends,' Toothless supplied, noticing her confused expression. 'They should turn up soon enough.'

And true to Toothless's word, a bunch of young Vikings barrelled through at that very moment, all crashing into their dragon friends. Stormfly smiled fondly at the growing bond between the younger generations. 'I'm sure they can come back inside with us,' she assured gently.

The children followed her and Toothless back to Hiccup's house, where they immediately set about resuming their play.

'What're they doing?' Stormfly asked Toothless, watching the children as they started gathering in a circle.

'Plotting against me, no doubt,' Toothless said dramatically, 'They've been demanding I let them ride me all day, yelling nonsense about being Hiccup.'

Stormfly laughed a bit at the mental image Toothless's words created, but stopped at the irritated look he gave her. 'Don't worry,' she said with a joking dramatic tone, 'I'll protect you!'

But she failed in that mission, as one of the young female Vikings managed to get on her back. "I'm Astrid!" the girl claimed proudly, hands on hips in confidence as she sat on the nadder's back.

"And I'm Hiccup!" the boy sat on Toothless announced, "So you have to marry me!"

Stormfly laughed at the child's statement. Toothless just groaned.

After a long and happy day spent together with his girlfriend, Hiccup was happy to return home. He was even happier to note that the house was still standing, though he did dread the sight he'd be met with inside.

'Toothless?' he asked quietly as he entered, not sure if his dragon would've attempted to get the children to go to sleep or not. As it turned out, he had.

"Aww..." Hiccup smiled slightly at the sight. Toothless lay in the middle of a pile of sleeping children, both dragons and Vikings alike. His wings were draped loosely around them, acting as their blanket.

On the other side of Toothless, Stormfly was leant against the stairs, curled around her own young. It appeared that the two had grown too tired from caring for the children - he wasn't actually surprised that Toothless had managed to rope in someone to help - and had fallen to sleep in their efforts to get the others to do the same.

"How cute," Hiccup commented mildly. He noticed that Stormfly had blocked his only way to his bedroom, so he made his way over to Toothless and settled in to his open-winged blanket. 'Night, bud.'
