Prompt: Booth/Brennan-tickling leads to sexytimes.

"No way, Bones. No way."

"It doesn't affect me, Booth."

"No way. Everyone has some spot, Bones, I just have to find yours."

"You can try but you won't succeed, and I simply hate to see you fail. I have no spot."

He's on his second glass of scotch and she's on her second glass of wine, and they are just in the right mood for this type of argument. It's a good night, Brennan muses to herself. End of a case, take-out, some alcohol and random, good conversation. They are back.

Booth is staring at her quietly, with a twinkle of mischief in his eye, and by the time she registers what it means, his hands are already on her feet - tickling.

She doesn't laugh.

He doesn't give up.

"It's not going to work, Booth."

"Party pooper," he pouts, next attack planned in mind already. He goes for her sides this time, and while she squirms a little, she still doesn't laugh.

She humors him, though, not backing away and letting him continue his attempts. Brennan kind of likes having their playfulness back and she's not about to screw with it.

Last attempt, then. He moves for the armpits.

And finally, finally, finally, she laughs. Booth suspects a bit that she's just trying to end the game but she's laughing, and he's laughing too, and she's squirming and trying to move his hands away, and they may accidently brush her breasts, and they are laughing.

They are laughing until they are almost out of breath, and he collapses on top of her.

Feels her heart beating loudly against his chest.

She feels his, too, and hers beats just a little bit faster.

Booth lifts his head from its place in the crook of her neck, and stares at her face closely for a millisecond before he dives down.

Brennan accepts eagerly, running her hands through his hair, over his back, down his body, back to his hair, to his back, roaming all over.

He places two hands on her face when he pulls apart just a bit, examining her eyes.

"You know, Endorphin is released as a reaction to tickling," she murmurs, and Booth dies just a little bit, because there's nothing better than Bones speaking squint, "also when you're excited. Or... or in love."

He chuckles, this is just SO Bones, and he loves her for it. "Endorphin, huh?"

She nods, and just before pulling him back for another heavy kiss she whispers one last fact -

"And, uh, also during an orgasm."
