Day One: Forbidden Fruit

If there was one rule between Myrcella and Sansa, it was that you don't date best friends' brothers.

Obviously Tommen and Bran and Rickon were no threat, but when Sansa had Robb and Jon, both just off to university, both strong and ripped and handsome rugby players, it was sometimes difficult.

But now Sansa had broken the rule: against all Myrcella's vehement advice, she had hooked up with Joff, who liked to place bets on how long a girl would put up with him whilst he got increasingly ruder and ruder to her- and sometimes more violent.

But Cella wasn't going to criticise now; Sansa had made her choices and she could be the one to initiate that discussion.

So when she arrived at the Stark household, and Robb answered the door…

Perhaps something had changed. Rule-wise.

'Oh, hey Myrcella!' He said cheerfully, running a hand back through his dusky red hair. It bounced lusciously and landed back on his forehead.

'Hey, Robb,' Cella replied, 'Back from uni?'

'Yeah, just for the weekend-' he answered, '-it's my mum's birthday. Anyway, come on in.'

He ushered her inside and they went into the kitchen, where Cella automatically got herself a glass of water. 'I'm parched,' she said, hopping up onto a barstool.

Robb smirked. 'I'd say make yourself at home, but it's clear you already have.'

'Oh come on Robb,' she laughed, 'I'm practically family.'

Robb frowned. 'Not quite.'

There was a strange silence as Myrcella thought over his peculiar answer.

What did he mean? Then it struck her. He didn't see her as a sister.

She swallowed harshly. 'Is Sansa about?'

'No, 'fraid not,' he said, turning to the fridge before Cella could see his red cheeks.

'Oh,' Cella said, awkwardly. 'I guess I should go home then.'

'No!' Robb said too quickly, 'I've not got anything to do, so…'

Cella smiled. 'Thanks, Robb.'

He smiled back at her sheepishly.

'So, how's Jeyne?' Cella asked, referring to his medicine student girlfriend, beautiful and smart and kind. She'd met her once and been sick with jealousy.

'Jeyne? Oh, we split up.'

'Oh, sorry.'

'No, don't be, she was a Liverpool supporter,' he joked. Then he went quiet.

'What team do you support?'

'I'm not really into football,' she said, eyeing up his biceps, 'I prefer rugby.'

'Oh,' he said, eyes hot as they met hers.

Off-limits! Her conscience hissed.

'I should probably-' Cella said, standing to go, but Robb leapt to his feet and kissed her hotly on the lips.

It was long and luscious, and Cella felt- somewhere in the back of her mind- embarrassed of her inexperienced, messy kisses under his expert lips. But mostly she felt hot, deliriously hot, and the heat went straight to the pit of her stomach.

Finally he released her.

'Don't tell Sansa,' she smiled, and leant up to kiss him again.
