Less than 1 minute ago she had been looking at samples, now, her light was off, Sherlock was rattling on about needing her to do something... but he wasn't spitting it out.

"Sherlock, spit it out, what do you need me to help you with?" She stopped him and he gulped and looked to John at her side as he sat down on the stool and smiled. He crossed his arms, gave Sherlock a nod and he watched Molly's face.

"I need you to rip my shirt open." He sighed and closed his eyes before looking at her so she knew it was serious.

Molly is convinced it's a game. Cruel humiliating game. Rip his shirt open?

"I don't understand." She set her hands down at her sides, not even tempting to reach for his shirt. He was wearing a normal white one, buttons went tight as he put his hands on his hips.

"I need to know how much force you are capable of unleashing. Proof for a young girl depends on it." He told her, she got to the point of almost being insulted before she crossed her arms.

"Young girl... while I am flattered to be compared to a young girl I am going to guess it is my build that is similar to hers right?" Molly asked him and he looked over her body again, taking in her measurements and nodding. She had slight figure, like the young girl being blamed, nothing else about Molly shouted young or girl.

"You're the only woman who is still the right height compared to me, and muscle mass." He cleared his throat, and moved his shoulders as if he was getting ready.

"How should this happen?" Molly asked him and he shrugged.

"Any way you can do it to prove it." Sherlock told her and he seemed to shut off his brain for a moment before looking down at her. She hadn't moved, so he moved to take her wrists in his hands, and he put her fingers over his buttons. "I don't really like this shirt anyways." He told her so she nodded and grabbed the middle of the shirt in her fingers, she could feel his bare skin under her fingers and while later she could revisit this, right now she had to do what he asked of her.

She tugged and barely got one to open, but it did not pop off. "Let me try something." She moved behind him, feeling her way to his buttons and ignoring his intake of breath when her fingers slid across his chest and upper abdomen. Her fingers slid inside the buttons again, she faintly scratched his skin before he tugged hard and the button below her bottom hand popped off the others simply undid themselves.

"Just a bit harder, from the front." Sherlock told her as he buttoned his others up and she moved to face him again. She tilted her head, thinking about where else to grab. She moved her hands higher as she faced him and tugged until some came undone and became loose, but not popped off.

Molly was woman enough to admit that she was getting very turned on as she kept skimming his skin, pulling his clothes... it was thrilling. For Sherlock he tried to breathe through it. He had never felt this kind of urgency to have the shirt just come flying off. He wanted her to do it, to get it done so he didn't have to control his emotions so tightly.

She tried every which way, she was in the middle of pulling down from the top when John laughed and stepped up. "Last one?" She asked them and he nodded before smirking wide at Sherlock over her shoulder as she then tried to rip down the shirt with the most force that she could. She didn't. She had three buttons come undone, but nothing more.

She tilted her head and then rolled her lips in. "Maybe the other way. Seriously last one." She said and she moved to pull on the shirt, getting it up, and as soon as she started to pull she didn't see two things.

One... Sherlock was getting hard and tenting his trousers... two, John noticed when she didn't and stepped in. "I think..." John grabbed the shirt and pulled, as hard as he could, and all the buttons went flying. "I think it was really a man." John settled his laugh with a smile as he looked from Sherlock to Molly. Molly had adverted his eyes, saving Sherlock from being more embarrassed than he probably should have been. Molly was blushing, stealing looks at his chest, and she was trying not to just open mouth stare.

She tried to listen as he started to make deductions. Before too long he thanked her as he slipped on his jacket and getting ready to leave. "Why didn't you just ask that girl to rip your shirt open?" She asked as John stepped out to make the call to DI Lestrade.

"She... well, she's in custody already and Lestrade won't let me see her to prove a point... a point that John just proved for me." He added and Molly nodded and wiggled her fingers. Trying not to remind herself just how soft his skin was under them.

"See you Sherlock." She smiled, taking a quick intake of his shirt open under his jacket before turning to get to the slides she had been looking at before.

"Good bye for now Molly." He called out as he turned and got his coat on before getting to the door. She watched him out of the corner of her eye, his mobile was in his hands and she took deep breaths to calm herself before getting back to work.

She went to sit down during her lunch, checking her phone, and seeing an unread message from Sherlock waiting for her. She saw that he wanted her to come over, to test it a couple more times just to be sure. He asked her to come over after her shift, that food would be provided.

She went over three hours after confirming that she would, and he had a new shirt on, all white just like the last, and she got to the couch and sat down with a sigh and looked around. "So, what other ideas were you thinking?" She asked and he stepped around the table.

"Do what John did first." He offered up his shirt, tight as the other one was, and she sat forward a bit, pulling at it, and while watching... she seemed to notice how it was affecting him. She pulled it a bit slower, getting it all the way out, and she got to the shirt tails and she stared up at him before she tugged. two buttons went flying and she inhaled deep.

"Guess that doesn't get me dinner does it?" She asked slowly and he smirked and grabbed her hands to lift her up.

"One more... start at the navel." He instructed and Molly nodded and looked down, she buttoned the third one that popped open but not off, and she felt his hands on her hips.

"What... exactly are we trying for this time?" She asked before she pulled again. She wanted to know, because John wasn't there to do it if she didn't do it this time.

"Testing the waters of something else that happened today. Willing?"

"You're going to have to be more specific Sherlock. What are you testing me on now? Strength?" She asked and she felt her face flame up when he shook his head.

"Compatibility."

"Meaning?"

"Chemistry."

"Of buttons?" She asked and he smirked his time, taking her hands in his, and pulling hard as he could, opening up the entire shirt for her.

"Of us."
