Irene Adler was slowly licking Sherlock's nipple. Suddenly she bit down hard. Sherlock grimaced but his curled toes gave away his delight. She slowly tilted her head up and stared thoughtfully, then determinedly.

Adler: I want to see you suck cock.

Sherlock: No, mistress. I don't want to.

Adler quickly struck his face.

Adler: I didn't ask whether you want to.

She slowly slid forward until her vagina was an inch from his face. She grabbed his head, pulling his hair with her fingers.

Adler: If you want this, you'll suck cock

Sherlock: Yes mistress

Adler pulled Sherlock's head into her vagina. He began greedily licking.

So it was settled. The next day at the hospital, Watson heard an erotic moan. He put his head in his hands, then pulled out a text on his phone. The text read: "Help me discipline Sherlock tonight"

That night, when Watson arrived at the flat, Adler was drinking champagne on the kitchen counter. When she kissed Watson, her breasts pressed against his chest. She grabbed his hand and led him to Sherlock's bedroom where Sherlock, naked, was bound on hands and knees. She slid off her pants and panties, then pulled Watson down by his shoulders so that he too was on his knees. She instructed Watson to lick, and Watson began eagerly. After a few minutes, Adler instructed Watson to stand and take off his pants. Sherlock tried not to look surprised when he noticed Watson's penis was much larger than his own.

Adler: Shove your cock down Sherlock's throat.

Watson: I'm not gay.

Adler: If you do it, I'll let you fuck my ass.

So Watson walked over and knelt in front of Sherlock's head. Sherlock inexpertly began slurping.

Watson: Sorry Sherlock, but you're terrible at this.

Meanwhile, Adler grabbed a bottle of lube and began working her fingers into Sherlock's asshole. After a few good slaps, she strapped on a strap on and thrust in. Sherlock let out a small scream muffled by Watson's cock.

Adler: Stop whining like a little bitch.

Eventually, she winked at Watson. She untied Sherlock then retied him on his back. Disappointed by his lack of on erection, she shoved a buttplug up his ass.

Adler: Watson, suck Sherlock's pathetic cock.

Watson: I'm not gay.

Adler: If you do it, I'll let you fuck my ass.

Watson began sucking Sherlock's cock.

Sherlock: Watson, you're better at this than Adler.

Watson: This one time in the army…

Once Sherlock was erect, Adler put his cock in her vagina and began riding him. She pointed Watson to the lube and ordered Watson to finger her. After a few minutes, she ordered Watson to fuck her ass. Watson came quickly, followed swiftly by Adler. Adler pulled off, leaving Sherlock erect with a buttplug still in his ass. Pulling her pants back on, Adler headed for the door.

Adler: I need to head out. Moriarty's been cheeky lately and I need to teach him a lesson.

Watson pulled on his clothes.

Watson: I need to go wash your stinking saliva off my cock.

After Watson left, Sherlock began to cry.
