The Other Woman

  Sherlock nearly choked on his tea and John almost dropped his cup before shooting a threatening glance his little sisters way.

     "You can sleep on the couch for now Lily." John said sternly.

     "She can use my room John." Sherlock said abruptly. John stared in amazement. He wouldn't even let him in there and now he is offering his room to a woman he barely knows.

     "What is wrong with that man?" John though to himself.

  Lily grabbed her bags and walked off down the hall towards Sherlock's room. Sherlock watched her go. His eye moved over her body. Studying every curve and line.

     "What are you on about Sherlock?" John hissed. "You barely know my sister and you're letting her stay in your room. You don't even let me in there!"

     "John, you really must calm down. She's your sister. You were going to make her sleep out here on this uncomfortable couch that you have had a wank on several times. I don't think she would appreciate that. Besides, In my room she can have all the privacy she needs."

  John fumed silently. He could tell something was up with Sherlock but he couldn't put his finger on it. The rest of the day Lily spent reading in her room while Sherlock poured over some case files Lestrand had dropped off earlier and John wrote in his blog. Darkness had just settled over London when John announced he was going out for the evening.

     "Lil, I'm going out for the evening. Meeting someone at the pub."

  Lilly's eyes flashed with mischievousness.

     "Got a date big brother?" a sly smirk crossed her face.

     "I don't really think that's any of your business little sister. I will be back later. Sherlock is home. Don't be worried if you hear gun shots. He shoots the wall when he gets bored. Please, behave yourself Lil."

  Lily waved him off and went back to reading her book. John wandered to the front door grabbing his coat and keys. Sherlock was standing at the window again deep in thought.

     "I'm heading out Sherlock. Lily is in her room reading. I will be home later tonight."

  Sherlock didn't answer. John figured he was in his "Mind palace" as he called it and made his way out the door. Once Sherlock heard the door shut he glanced over his shoulder. Lily stood against the wall. She was wearing a white tank top and black boy shorts. Her loose ringlets framed her face as the warm light of the room made her skin look almost ethereal. She had his violin in one hand and his bow in the other.

     "Teach me?" she asked gently walking towards the detective.

  Sherlock smiled and took the violin from her. He moved around her till he pressed against her back. Slowly, he moved the violin under her chin and placed her hands in the correct areas. Suddenly, she began to play. Moonlight Sonata by Beethoven. Sherlock stared at her in shock.

    "Cleaver girl. Was that your plan to get me close to you?" He whispered into her ear.

  She laughed.

     "It worked didn't it Mr. Holmes?"

  Sherlock moaned. His name one her lips made his cock ache with need. Lily put the violin on the couch and stepped close to Sherlock. He couldn't bear it any longer. He had to have her. Sherlock had never felt anything like this before. It was a driving need. Almost painful to him. He pushed Lily up against the wall and kissed her forcefully. Her lips melded with his and a little moan escaped her mouth as his tongue ran along her own. Her finger's worked deftly at Sherlock's buttons before she got impatient and tore his shirt open sending the remaining ones across the room. A low growl escaped Sherlock's throat as he picked her up and she slid her legs around his waist. His erection was beginning to throb. As if she knew, Lilly quickly jerked down the lounge pants he was wearing letting his length spring free. Her deft fingers slid along his hardness causing him to moan into her shoulder. Lily slid her panties to the side and helped guide Sherlock inside her. They both gasped in pleasure as her hot wetness surrounded him. Sherlock thrust slowly at first feeling every inch of her on his cock. She gripped at his back and moaned loudly.

     "Oh Sherlock...oh"

  He began to thrust faster now. The orgasm building inside of him. He knew he couldn't hold out much longer. He could feel her tighten on him close to the brink as well.

     "Oh Lily, I'm going to...."

  Before the words had a chance to pass through his lips he felt the orgasm roll through him as her tightness began to spasm. Their moans became entwined as Sherlock gave a final hard thrust. Staying inside of her Sherlock carried Lily to the couch where she straddled him, laying her head on his chest. 

     "What do you say we don't tell my brother Sherlock? I promised I would behave."

     "I didn't." The detective said with a satisfied smirk.
