The hand on his arm was so delicate that he could barely feel it. He couldn't deny the subtle beauty of his guest, the long flowing hair that fell down her back was the thing that had attracted him to her almost instantly. She was fairly mousey, but he had sensed the submissive streak run through her like a lightning bolt the minute they had met. They had been 'dating' for over a month now, and it had been exactly 28 days since she had first submitted to him. Mycroft, a skilled Dom, a man who had had numerous submissives, had zoned in on her almost instantly. She would be the perfect addition to his collection, and if he was correct, this pet would have the added bonus of irritating his brother.

"On your knees, my pet.." he whispered softly to her, once they entered his room in the Diogenes Club, a room in which they were safe to speak, Mycroft's own private quarters. Molly looked up at him and instantly obeyed, dropping to her knees before him. Mycroft sat down, and Molly looked up at him.
"Now, now, Miss Molly.. what did I teach you?" the lab technician dropped her gaze, and was rewarded with a "Good, good.. Now, my dear.. you know what to do.."

Molly shed her clothes quickly before crawling towards him naked and kneeling between his legs. Her fingers moved to his belt and pulled it from his trousers completely, placing it on the ground beside him before working open his suit trousers. Mycroft stood up and looked down at her, sliding his trousers down before sitting back down and holding out his hand. The minute he held out his hand, Molly bent and picked up his belt between her teeth and dropped it into the palm of his hand.
"Good girl.. Carry on.." Mycroft smirked. Molly kissed along the inside of Mycroft's thigh, her hands moving to cup his testicles, stroking them gently. She took him between her lips, running her tongue over the underside of his shaft, massaging him gently as her lips slid along his length. Almost instantly, the fingers of Mycroft's free hand were tugging her hair, a feeling that made her jump at first, but now it made her feel safe and secure. She continued what she was doing, sucking and licking Mycroft's cock until she felt the sharp sting of leather against her back and jumped.
"Molly.." his voice warned, and she relaxed again, forcing him further into her mouth until her nose was resting by the thick curly hair by the base of his cock as it's tip sat at the entrace to her throat. She began to breath through her nose like he'd taught her, as his belt hit her back repeatedly for nine more strokes until eventually, he came down her throat.

He removed himself from between her lips and rose from his seat, pulling his trousers back up just as there was a knock on the door to his office.
"Stay.." he spoke in his most commanding voice as Molly went to move, to hide from the prying eyes of whoever was at the door. She stayed, though, as commanded, her back to the door. Mycroft pulled it open and looked at the Diogenes worker with a raised eyebrow. Silently, the man handed him a note and Mycroft glanced at it before handing it back, nodding at the man.

Mycroft moved to sit in his chair by the fire and called Molly over. She crawled on all fours, sitting by his feet as he picked up a newspaper from the table and reading through it, ignoring her. After a few minutes, his fingers began stroking her hair as he continued reading. Molly rested her fingers on her thighs, closing her eyes as she relaxed under the gentle touches of her Master. After a few more minutes, Mycroft cleared his throat.
"We'll be having a visitor shortly, my pet.. Better go fetch your collar. You may walk."

Molly rose to her feet and moved to the cupboard in the corner, pulling out the pink leather collar Mycroft had had custom made for her a few weeks before, and carrying it over to him and kneeling before him. With a gentle smile, Mycroft fastened the collar around her neck.
"Perfect, as always..." he smiled "Good enough for visitors.. My brother will be here shortly."
Molly's face went pale and she swallowed. Sherlock would see her like this, being submissive for his brother. The thought filled her with fear, and yet, a part of her was rather excited by the idea.
