Hello! Just a one-shot drabble with Molly and Sherlock who should have been together at the end despite when the show despite what Moffat thought. Enjoy!

Molly peered over at Sherlock who had been looking into the microscope stock still for the past thirty minutes. It wasn't unusual that Sherlock went into his mind palace while working in the lab, but he never was there for so long.

They were in the lab of St. Barts close to ten at night. Molly liked working at night when it was only the silence and dead bodies. They didn't judge you or make you talk to them. The silence was good.

"Molly," Sherlock interrupted her thoughts. "I'm wondering if you can help me with an experiment."

She stared at him. "Of course Sherlock. What is the experiment?"

"How would sex between us be." Molly froze for a moment as her mind blanked. "You see," he continued. "I've run the scenario in my head thirty-seven times with various results. Eighty-six percent of which end in both of us reaching climax within fifteen minutes."

She set her tools down and looked at him. "Why are you asking about us?"

Sherlock stood from the microscope and came towards her. "Come now Molly, you're smarter than this. We are very compatible with each other. You've given me a key to your flat…"

"I don't believe I actually gave you a key."

He waved his hand dismissively. "The point being we've shared many nights sleeping in your bed."

Heat rose to her cheeks. "Nothing happened."

"It doesn't negate the fact that you wanted something to happen, as did I." Her eyes widened as he smiled. "I could have gone to my brother's house when I faked my death, but I wanted to stay with you. Now, will you please help me with this experiment?" He gave her his best puppy dog eyes.

She looked at him, mentally assessing to see if he was high. Determining he wasn't, she smirked and put her hands on her hips. "So what's your hypothesis?"

He smiled. "My hypothesis is that sex between us would be mutually satisfactual and highly addicting." He stepped towards her with lust in his eyes.

"What materials will you need?"

He put his hands on the steel table, trapping her. "You, me, a surface of some kind like the table here." Molly stepped back into the table, hitching her breath. "It also needs to be quiet with no others around. I don't mind others watching, but I don't think you would."

Molly bit her lip to keep from moaning. "What are the steps?"

He bit down lightly on her neck, below her ear, causing her to moan out loud. "Step one is kissing." He tipped her chin to look her in the eyes. Slowly capturing her lips.

Electricity shot through her system. She had fantasized about him many times but thought it would only be that, a fantasy. She was lost for words at the feelings of what his lips were doing to her.

"Step two would be the addition of hands," his hands slid from the table to her waist and pulled her flush against him, feeling his erection between them as they kissed. After a moment, one of his hands left her waist to land on her breast. As he kneaded her breast through her jumper, Molly moaned into his mouth.

"What's step three?" Molly asked when she arched her head back.

Sherlock immediately nipped at the exposed flesh of her neck. "Step three would be the discarding of clothing." He stopped kneading her breasts to shirk off her lab coat. Molly broke contact with his electrifying lips to assist with her lab coat and jumper before helping with his suit jacket. She pulled his shirt out from his pants to touch his skin, earning a moan from his lips. The two tore off one anothers clothing until she was left in her knickers and him in his pants.

Molly's breath was erratic as she looked at his sculpted body. Broad shoulders, chiseled torso, firm muscles that were gentle with his grasp on her. She looked to his pants to see a large bulge and smiled. "A reaction should be noted in step three," as she nodded downwards.

Sherlock smiled. "For both subjects it would seem." His hand slipped between her legs and felt the wet knickers. "It seems the experiment is proving positive."

"I would agree," she breathed as he kept stroking her slit. "What's step four?"

He leaned close to her ear. "What do you want, Molly?" Her breath hitched. "Tell me, Molly. What do you want me to do to you?" He pressed against her clit through the knickers.

"I...I…"

"What?" His teeth lightly bit her earlobe.

"I want you to shag me."

"Your wish is my command." He stopped playing with her and moved to her hips. His hands hooked her knickers and slowly pulled them to her feet, kissing his way down her legs. When he came back up, he saw her eyes were dilated and darker. He picked her up and set her down on the cold table.

Molly apparently didn't notice the cold of the table as she pulled Sherlock between her legs and into a heated kiss. "Keep going," she encouraged. He responded by squeezing her breast again. She took this opportunity to slip her hand down his pants and squeeze his cock.

"God, Molly. You feel incredible, but if you keep that up, this experiment will end prematurely." He removed his pants and his seven inch cock sprang free. He saw Molly's eyes widened a bit. "Hey," he said softly, pulling her attention back to his eyes. "Are you ready for step five?"

She took a breath. "Yes, Sherlock." He smiled and lined his cock with her core. As he kissed her, he slowly pushed into her. Both moaned when he was fully sheathed. "Oh, William, you're bigger than I anticipated."

He liked hearing his given name on her lips and returned with a harder thrust. They continued thrusting hard with one another, Molly matching his strength. Sherlock felt her vaginal walls tightening around his cock. He slipped his hand between their bodies to press on her clit. "Come for me, Molly."

Molly cried out in pleasure as she came. Her speed and thrusting onto his cock tipped Sherlock over the edge and he came inside her. They slowed down after a few intensive thrusts, both panting hard.

"I believe I've proven my hypothesis," Sherlock said through pants.

Molly chuckled. "I believe you have. That was very satisfactual and I could get addicted to this."

The two chuckled together. Molly moaned as Sherlock thrust slowly into her once more before pulling completely out and letting her get dressed. They were both silent as they dressed, lost in their own thoughts.

"On second thought," Molly said once she was fully clothed. "I don't believe you've proven your hypothesis yet."

Sherlock quirked a brow at her. "Enlighten me."

"In order to prove your hypothesis, you have to have had multiple experiments with a few variables."

Sherlock's mouth turned up into a grin. "Then let's get started."
