Irene makes Mycroft spank her

Rated: R
Pairing: Mycroft/Irene.
Summary: Exactly what it says on the tin.

"I hope you realise that this is highly unusual, Ms. Adler," Mycroft Holmes says. He's looking at her with indifference, although the effect is slightly ruined by the rising flush in his cheeks. He circles her until she can see nothing but his long shadow.

Irene smiles against the back of her hands. She is wearing her battle dress, but her posture speaks of surrender. She is her knees and forearms, hands clasped before her as in a prayer.

"Consider this a parting gift, Mr. Holmes," she says, and rests her chin on her knuckles. "I always suspected you'd make a fine student. I'm only sorry I won't be around long enough to teach you."

The whip flies at her backside in a wide arc. She doesn't flinch when it lands, but lets out a soft sigh in appreciation.

"Surely you can do better than that?" She purrs. "I've been very naughty."

"Yes, and you will be punished for that," Mycroft says. He's studying her, she knows. More calculating than leering, and she shivers for the first time since she stepped out of her dress.

"But I do wonder why, of all people, you chose me for this task, Ms. Adler."

Irene smiles again. She curves her spine, and the sound of his hitched breath makes her skin tingle.

"There are very few people I'd allow to bring me to my knees, Mr. Holmes." She resists the urge to lick her lips, and adds, "A woman must have standards."

He considers this for just a moment. She can practically hear the gears in his mind turning.

"Begin counting, if you please," he says at last.
