Disclaimer: Not my sandbox, I'm just playing in it. Thanks to all involved in making Chuck such a fantastic show.

'What is this?' Chuck asks, sprawled naked and sweaty and half-asleep across Casey's bed.

Casey quirks an eyebrow. 'If you don't know by now, you aren't old enough for what we just did. Twice.'

Chuck turns his head and frowns; well, as much of a frown as he can manage, having been fucked through the mattress and come hard enough to drop his IQ by several points. Twice. 'No, I don't mean that. The sex. That's fine. More than fine. Amazing, even.'

'Then what?' Casey asks, as close to indulgent after amazing sex as he ever gets.

'This,' Chuck says, waving a hand to encompass them both. 'You and me. What would you say we are? Fuck buddies? Friends with benefits?'

Casey scowls, his good mood evaporating like the sweat off Chuck's back.

'You aren't my boyfriend because we can't hold hands in public or kiss or go on dates,' Chuck says. 'Which isn't to say I wouldn't, you know, if we could. Because I would. If you wanted.'

Casey's scowl recedes. 'So what, you want a label?'

Chuck shrugs. 'I guess.'

Casey runs a hand over Chuck's hip and down his thigh. 'Lovers,' he rasps and bends his neck to suck lazy kisses on the curve of Chuck's shoulder.

Chuck's breath hitches and he moves closer, feeling a resurgence of interest. 'Lovers,' he echoes breathily. 'Okay, lovers.' He tugs Casey until the big man moves over him and settles between Chuck's legs. 'Up for round three?' he asks huskily.

'Mm,' Casey grunts, pressing him into the mattress.

Lovers. Chuck can live with that.
