First I love You

"I love you."
The words slip out of her mouth one day while she's laughing at some dumb joke he made.
They both freeze up the minute those 3 little words leave her lips.
He should be terrified. He should want to run. Because he's Barney Stinson and he doesn't do love.
She should be terrified. She should want to take it back. Because she's Robin Scherbatsky and she's only said I love you to one guy before this. Because loving Barney is dangerous, and telling him is even more so. They look at one another for a second and then Barney's mouth captures hers.
"Say it again." He murmurs.

He's breaking all his rules he should of been out the door but he's been waiting to hear Robin say that for the past year. He's in deep he realizes and that's really not as bad as he thought it always was.
She giggles against his mouth, entangling her fingers in his hair and tells him, "I love you Barney."
He sighs in contentment and takes a shaky breath, preparing to utter the phrase he hasn't spoken in years.
"I love you too, Scherbatsky."
And now it's out there and they realize they're in this together, this is real.
And sitting there, getting lost in gentle kisses and lingering touches, they couldn't be happier.
