It was D.C.s hottest day of June since records began and Booth could feel all 104 degrees burning his skin. He had already discarded his jacket, rolled up his sleeves and opened the first few buttons of his shirt underneath his loosened tie, but there was only so much he could do to try and cool himself down while still fighting the need to strip completely.

On their way back from the diner Booth and Brennan had stopped for ice-cream before walking Brennan back to the lab.

They both sat on the steps of the Jeffersonian, savouring the last few minutes of their lunch break. Even with the AC blasting, the lab felt like a sauna and was excruciating to work in.

Trying to keep up with the melting of his ice-cream, Booth ran his tongue around the top of his wafer cone catching all the vanilla droplets.

Booth could feel Brennan watching him and he turned to look at her staring at the way his tongue moved around the cone.

Remembering their conversation from the other day in the bone room and looking at the desperation in her eyes, he slowed his mouth down. Caressing the entire cone with his tongue and lips and making sure he was driving her crazy and he watched her as the beads of sweat slowly rolled down her chest.

Brennan quickly snapped out of her gaze as she realised what he was doing. She looked down at her own ice-cream which had mostly melted and had ran down the cone and onto her fingers.

She look at him straight in the eye as she brought her sticky, vanilla fingers to her mouth. Slowly inserting one finger into her mouth and sucking on it. She closed her eyes and let out a slight moan as she sucked off the vanilla goodness.

When a small dollop of ice-cream dropped onto his crotch, she quickly licked the corner of her napkin and reached over wiping up the mess.

He grabbed the ice-cream cone out of her hand and stood up dropping both cones into the bin next to them. His fingers wrapped tightly around her wrist and he dragged her into the Jeffersonian and into the disabled toilets locking the door behind them.

"Booth, what are you doing? I have to go back to work."

"What do you think i'm doing?" He picked her up and sat her on the sink. He rubbed his hands on her thighs, gliding her skirt up to her waist. "And you don't need to go back to work for another 5 minutes. I'm sure Cam won't mind if you're a couple minutes late."

"This isn't a good idea."

He placed his hand on her soaking wet panties and gently rubbed against her. "Tell me to stop and i will."

Instead of saying stop she let out a small moan and he smiled as her head tipped back resting on the mirror on the wall.

He moved his hands looping his fingers into the waist band of her panties and pulled them down.

She let out a deeper moan as he inserted one long finger into her and then another. "God, Bones. You're so wet." He pumped his finger a few times before pulling them out completely and she groaned in desperation. He popped both fingers in his mouth and licked them clean, "Wow. You taste even better than i ever imagine." He bent down, spreading her legs wider and placing them on his shoulders.

His tongue rimmed her folds before rubbing it hard against her clit.

A small gasp escaped her lips and her hips lifted pressing herself into him.

Booth dug his tongue deep into her core. Again and again. Faster and stronger. He could feel his insides throbbing against his mouth and he could feel that she was about to orgasm. He brought his hand up to join his mouth and rubbed hard circles against her clit.

She leaned forward and purred in his ear. Her moans got louder and just as she hit her climax she remembered where she was and bit her lip trying to muffle her cries.

When he finally pulled away from her he gave her a long hard kiss before handing her back her panties.

"Thank you." she said. Both thanking him for her panties and for what he just did to her.

"The pleasure was mine and look, you're only a couple minutes late." He looked down at his watched as she headed for the door.

...

10 minutes after arriving back at her office, Brennan sat with her head in her hands, staring at the desk as she replayed in her head what Booth had done to her.

Angela knocked on her office door and walked in, "Hey Sweetie, Booth told me to give you this." and she handed Brennan a post-it note.

Brennan let out a small laugh as she read the words 'Round 1 to Booth'

Angela gave her a strange look, "Anything i should know about?"

"No." She laughed again, "Just a game me and Booth are playing."

"Wow Bren, he must be pretty good if he beat you."

"He's incredible, but don't worry. I'll win round 2."
