Barney's been teasing Robin a lot in this fic, so I thought it was time she gave him a taste of his own medicine.

Set on 18th August 2009, between Seasons 4 and 5.

He remembers Lily drooling over Marshall's calves, and wonders if the same thing would work on Robin. Okay, maybe not his calves (the chicken-legs thing may be ever so slightly accurate), but Barney loves to make her furious and turned on, so one evening before she comes over he takes off his jacket, tie and shirt, and answers the door bare from the waist up. Robin narrows her eyes when she sees him, but pecks his cheek anyway (a sort of habit she's fallen into lately, though neither of them mentions it).

"Where's the shirt?" she asks.

Barney snorts, "Please,"

She gives him a puzzled look but shoots back his sexy, challenging smile. She returns it, looking him up and down with satisfaction as they both inch closer, thick chemistry zapping between them like static. When they're so close that their knees touch, Robin puts a hand to the back of Barney's neck and kisses him slowly – close-mouthed, but lips soft and inviting. The soft lips then trail down his chin, neck and collar bones. She smooths her hands over Barney's arms as her mouth slides down the centre of his chest, cool against his skin. Mmm. Normally they chat for perhaps thirty seconds before the intimacy starts, so Barney's pleased that he's managed to cut to chase (though he values talking and mocking and laughing with her much more than he admits). And yeah, this is lovely. Robin drops to her knees to lick across his abdominals, running her tongue along their dips and contours, relishing the taste of him. He's loving it as much as she is- it certainly makes his daily routine of sit-ups worthwhile. Triumph growls happily in Barney's stomach as she rubs her face against his body, lapping at him like a cat. Robin's mouth searches to just above his belt, and oh yes, this is going somewhere very nice. She presses kisses to his skin about an inch apart as her lips brush repeatedly back and forth across him. Barney's trying to be patient, but he's itching for her to undo his belt and send her kisses lower.

He clears his throat and gives her a well, hurry up then look.

Robin smiles coolly, purrs, "Wait for it," and kisses him again.

She wraps her arms around his legs and traces slow, gentle circles across the inside of his thighs. Oh, come on. Barney hisses out a breath, blood pulsing inside him as he grits his teeth. Her fingers feel light against the thin fabric of his trousers which makes him even hungrier for her.

Robin's hands and mouth are inches from where he needs either of them to be, touching him in the most tantalising way, making him feel hot and uncomfortable.

"Robi-in," he whines. She stops and looks up at him, victory clear on her face- because she has made Barney Stinson moan her name. It's Point Robin but he doesn't care because her lips are on his stomach again and her fingers are stroking his legs. God, she's good. The way she's almost giving it to him is excruciating- and even more excruciating is that knowing that he'll let her do it. Barney wants her so badly that he'll let her make him the one to beg, let her make him sweaty and tight and breathless. It isn't just Point Robin, its Game, Set and Match Robin- part of Barney hates that he's allowed her to win- but most of all he just has to have her on him. Barney groans a couple more times, and a third when her hand finally drifts up to his belt. Robin undoes it at a teasingly slow speed, but thank God this is finally heading (what up) somewhere. Barney hums happily, loosening his neck and closing his eyes…

Abruptly, Robin lets go of him and stands up and moves away. She's so fast that Barney doesn't register. Robin flashes him an innocent smile and says brightly, "Sorry, I forgot- I need to help Ted out with something,"

The door opens, closes, and she's gone.

Silence.

Dazed and blinking, Barney takes a few moments to clarify what just happened. Robin left. She kissed him, touched him, turned him on fire- then left, citing commitments to her live-in ex-boyfriend as the reason. Jesus, she's good. She's one step ahead of him. Sends him insane.

A cocktail of admiration, anger, jealousy and lust boils and bubbles and swirls inside him. Barney isn't sure if it's delicious or disgusting.

She will be the death of him. He'll let her be, and he won't care.

His breath's returning and, with a groan, Barney stumbles backwards onto the couch. It's a good job he's been secretly (or not-so-secretly) filming their recent nights together - otherwise he's not sure that he'd survive this.

Fin.

Thanks for reading, I hope you liked it. Whatever your opinion, please review (especially if you've favourited!)

Have a lovely day.
