Notes/Warnings: Read the disclaimer on my LJ


Surprisingly she's the one who suggests it, then laughs as Charlie gapes in shock.

It's just sex she tells him blithely.

Just.

And Don's just his brother.

Charlie's stubborn, but Amita's persuasive, persistent.

They'd agreed to indulge each of their deepest sexual fantasies before marriage, ostensibly to curb the desire to wander.

A threesome - with two men - had been on both their lists.

The only problem was with whom?

She winds up winning him over with the most unexpected argument.

She uses logic against him.

The problem, she'd argued convincingly, was that they had to pick someone they could trust to keep the liaison a secret. Charlie's reputation in the math community could bear the brunt, but his contract work with the NSA could dry up overnight if even a hint of blackmail surfaced.

And who can you trust more than family?

Amita was smart enough to know attraction wasn't the issue: Charlie had hero worshiped his brother his whole life.

She invites Don to have dinner with them at her apartment, just three people having a normal casual dinner party.

He compliments her curry, she flirts with him.

Charlie watches. And gets hard.

She excuses herself during dessert and disappears into the master bedroom leaving the door open just an inch.

Charlie excuses himself a couple of minutes later and follows her into the bedroom.

He leaves the door open an inch as well.

The sex is noisy, passionate and there's no way Don can't hear them.

They return at the same time, sit back down and finish their dessert.

Don thanks them for a lovely evening before he leaves and kisses Amita on the cheek.

The next time she invites him over, they sit on the couch and watch a movie.

Charlie's hands start out in her hair then roam to skirt the edges of impropriety, finally skimming over her breasts as she's almost sitting in his lap.

When she finally rises to go make coffee her hand lingers on Don's shoulder, fingers drawn up his bicep before resting near his open collar.

She asks him what he takes in his coffee. Does he like it sweet or dark and harsh?

She jumps a bit when he rises unexpectedly, with a long glare at Charlie.

He puts his hand at the small of her back and guides her to the kitchen, telling her he'll help her make the coffee.

She asks him when he's putting Splenda in his cup.

He pauses, nods when she asks if he heard her.

She tells him just to think about it.

They have coffee. They finish the movie. When he leaves, Don gives her a kiss on the cheek and slips an arm around her slender waist as he does.

He invites them over next.

He's a surprisingly good cook and they linger for hours over the dinner table before Don kisses the back of Amita's hand like a gentleman.

Then he turns her hand over and kisses her palm.

His eyes are on Charlie not her.

He sucks one of her fingers in his mouth and waits for Charlie to respond, probably figuring jealousy will get in the way.

Charlie's breathing quickens and his mouth falls open. He's entranced.

Don leaves his chair and goes to stand behind Amita, pulling her hair to the side before lowering his mouth to her neck, his gaze never wavering from his brother.

As amazing as it feels Amita can't help but think the more intimate connection is between Don and Charlie.

She arches her body back in invitation, but he takes his time. Hands explore her bare arms. His tongue swirls in her ear.

Then he stops and takes the dinner dishes into the kitchen.

When he kisses Amita goodnight it's on the mouth with his hands intimately low on her hips.

It's a good thing they brought Amita's car because they put up the top and fuck in the parking lot of Don's complex. It's frantic - almost animalistic - and hotter than anything they've ever done, leaving them gasping so loud they wonder if Don heard from his open second story window.

If this was Don's test, they clearly passed it.

Charlie rents a mountain cabin for a weekend far from the tourist towns. He tells his co-workers he's going up to hike and work on his Cognitive Emergence Theory in the quiet of the forest.

Amita leaks to Larry that she's planning on crashing Charlie's sojourn for a romantic getaway.

All Don has to do is say Charlie's going away hiking and Megan practically begs him to go along, to take some time off to unwind for a change.

If she only knew.

Amita arrives first and when Charlie lets her in they make love, slow and tender, cementing their bond before it's tested.

Don's late and it's almost nightfall by the time his SUV pulls up.

Amita makes dinner in the tiny propane powered kitchen, but it's Don watching Charlie across the table that makes her hungry. He's looking at his brother like he is dinner.

Charlie packed well and the food is excellent. Dessert is an elaborate Tiramisu, decadent and rich.

They both watch Don eat his portion. He relishes each mouthful, rolling it over his tongue with obvious pleasure.

When he takes the last bite and puts his fork down he rises from his chair, stalking around the table - past Amita - to Charlie.

He pulls his brother from his chair, presses him up against the nearest wall and kisses him.

Charlie melts into coffee cream sweetness as his brother plunders his mouth and Amita gasps, body gone aflame from the heat spike in the room at the sight of the two of them together.

It takes a moment before she can think or even move, but once she does, she slips behind Don and starts to pull his shirt out of his pants.

Charlie catches on and between his unbuttoning and her tugging they get Don shirtless.

He turns and pulls Amita into a kiss next, letting Charlie suck one of his fingers as he presses their bodies together.

Before they know it, he's stroking Charlie through his pants and has his fingers slipped inside Amita's bra.

It's quite possible he's done this before.

Somehow Charlie gets a measure of control back and pulls off the wall. They surround Don, attacking him both at once with mouths and hands on heated skin.

Charlie's tentative about touching his brother's cock for the first time, but once Amita joins their hands together they slip inside his boxers and earn a low rumble of a groan in appreciation.

Any sort of hesitation gets thrown out the window when Charlie drops to his knees and sucks his brother's cock into his mouth.

After that, it's careless stripping on the way to the bedroom, mostly the brothers divesting Amita of all her carefully picked out undergarments.

They collapse on the mattress in a naked tangle, already too warm for comfort, and then it's all logistics - the science of sex.

Don fucks Amita on her hands and knees as she sucks Charlie off.

The brothers suck each other off as they jointly finger fuck her.

Charlie slips between her legs as Don presses into her from behind.

When Don fucks Charlie for the first time, she watches, sucking his cock as his brother's steady strokes send shudders of ecstasy through him.

When Charlie comes she sees something break in him, a final layer peeled away to the man beneath she'd never seen before.

She's the last to fall asleep, wondering about what she's seen, what they've done.

They spend the morning exploring Don's naked body, mapping it with their tongues and fingertips, memorizing it for future fantasies.

Today is about voyeurism.

Don masturbates as he watches Charlie and Amita have sex in the shower.

Charlie paces and struggles not to touch as Don fucks Amita long and slow.

When it comes time for Don to fuck Charlie they do it face to face - eyes locked.

Amita's mouth is dry and a part of her wants to protest at this amazing connection taking place that she's not a part of.

Three decades together have given them an intimacy she can't come anywhere near.

She fidgets in her chair, aching inside because Charlie never makes wanton desperate noises like that for her.

They eat voraciously at dinner and talk little.

Dessert is chocolate cake, dark and dense.

They fall into bed after the meal and are lulled into sleep, exhausted from the day's play.

Amita wakes to find Don between her legs. She spreads them, welcoming, even before she opens her eyes.

A moan makes them flutter open and she's looking up at Charlie fucking Don as he fucks her.

She comes twice, once just from watching them, once because she can feel Charlie's familiar movements through Don's body and the idea turns her on more than she imagined it could.

She drifts off once they're done and assumes they do the same.

She wakes again to hear quiet voices and movement in the bed.

Charlie's breathing his brother's name into his ear, panting and clutching at his back as Don slides into him. His hips pump with a restrained frenzy, as if they don't mean to wake her, but can't help this overwhelming craving for each other.

She turns on her side, facing away from them, pretending to sleep as she secretly fingers her clit, coming when they do.

They have one last time on Sunday morning.

Charlie slips into Amita's familiar heat then Don settles behind him, gripping his hips as he buries himself inside his brother.

Charlie's simply overwhelmed. An unearthly sound floats up out of his core as he quivers in mind-blowing bliss.

He's lost in his own pleasure and it takes Don's hand, snaking around, to bring her to her own completion.

Don pets Charlie through his recovery, soothing him until he can speak again.

Amita slips out of bed to go take a shower.

She stays in there a long time.

They pack up that afternoon and go home.

The wedding gets postponed.

The sex is better than it's ever been and Charlie's happy.

It's Amita who wonders if perhaps forbidden fruit should have stayed untasted.
