Chapter 10 : Celebration

Cecilia was down trodden as she returned home late. Sarah had set her up with someone she knew from her gym. She had not been able to give a good excuse for declining, she couldn't tell anyone what had been developing between her and Sherlock. And Sarah wouldn't take 'no' for an answer. So she went out to dinner with 'Stewart'. He might have been a lovely man but it was a waste of an evening. She could not help to compare him to Sherlock, and he came up so very short. While on the date she had chided herself for wearing her 'hot-date' clothes; low cut black blouse, dark jeans, black lace underwear…why was she trying to impress this over-muscled imbecile? As soon as was appropriate she cut the date short, declining to get drinks. She even paid half the bill upon leaving so there would be absolutely no obligation owed to 'Stew", as he insisted she call him. At least Sarah had agreed to never set her up again.

She walked through the entranceway of 221 Baker and looked up the stairs to check in anyone was in. There was no light under the door. She sighed; yet another day without seeing either John or Sherlock. "This is their regular schedule" she reminded herself, Sherlock was usually working a case. Cecilia had been living alone in her Aunt's flat for what seemed like to long, and the few days without John and Sherlock showed her just how lonely she was. She was becoming a little homesick. Maybe she should go visit her Aunt soon, get away for a weekend…

Lost in though she walked through the dark apartment. She didn't bother turning on the main lights; she was just going to go straight to bed. She opened the door to her room and crossed to her bedside lamp and switched it on. Startled, she let out a yelp as she saw that there was a man reclining on her bed.

"Sherlock! Why do you always try to scare me? What are you doing here?" She yelled.

"I solved it!" he had his hands behind his head a look of satisfaction on his face. He was wearing a white shirt, mostly unbuttoned and uncharacteristically un-tucked form his black trousers.

"Oh!" She responded with an irrepressible smile. She smiled more for knowing that she would be seeing him more often for a little while than for his accomplishment. "That's wonderful Sherlock…but what are you doing here." She indicated her bed.

He sat up, there was a moment of silence while they locked eyes. He took her hand and pulled her down on the bed. He was on such a high from solving the mystery that he felt like he could do anything in the world. Sherlock kissed Cecilia deeply, his tongue finding admittance. She exhaled sensually. There had been so much tension building between the two of them that this triggered a torrent of animalistic passion.

They were immediately writhing against each other; they struggled with each other's clothing. Cecilia undid her jeans and slipped out of them; she was thankful that she had dressed for a date after-all. Sherlock pulled her blouse up over her head. His hands ached to caress her curves. This had been put off far too long, interrupted too often. Unencumbered by her clothes Cecilia began kissing his neck. She could smell his masculine scent and it was something she hungered for. She pushed back his unbuttoned shirt and the black lace of her bra grazed his chest. He moaned, his voice husky with desire. He pulled away and stood up by the bed. His light eyes were filled with lust and he moved as though he were a prowling jungle cat. A smile spread across Cecilia's face, she couldn't remember the last time she had wanted a man so badly. She slid her bra off and got up onto her knees grabbing Sherlock's belt and pulling him towards her. She began kissing his abdomen, feeling his heat through the fabric of his pants. Sherlock's eyes locked onto hers and if felt like they bored into her soul. He smiled, perhaps seeing that she truly wanted this, or perhaps anticipating the satisfaction he would take. He pushed her back onto the bed, roughly, as he shed the rest of his clothing. They were one again, kissing each other wildly, grinding their bodies against one another.

Sherlock could not wait any longer, thoughts of this had clouded his mind so often in the past days that he had struggled more than he should have on the case. He took that which he hungered for and groaned with desire and relief. Cecilia gasped and wrapped her arms around his neck. They were grappling for control over their bodies, both wanting to make it last longer, but yearning for climax. Sherlock had never experienced such visceral pleasure. For the first time in so many years he was not in his head, he was in the moment. For once he was not analyzing and observing he was just experiencing. He was indebted to Cecilia; thus far she had been the only woman to arouse this type of passion in him. Again and again her embrace sent waves of pleasure crashing over him.

Cecilia clawed at his chest, his back, she entwined her fingers in his wavy hair. He delighted in her fervor. Sherlock could see her racing pulse in the hollow of her throat. He could see, hear, and feel her enjoyment and he lost control. He threw back his head and released, grunting and sighing her name. He shuddered as the ripples of pleasure slowly faded.

He collapsed, utterly spent, resting on top of her. She could smell his hair, and put her fingers through it again, reveling in this moment. Languorous, he smiled and slowly closed his luminous eyes. He inhaled, smelling their mixed scent and he hoped he would smell it on her tomorrow.
