***Still don't own any characters except Ri. Please leave me a review!***

Night descended before Sherlock regained consciousness. He found himself pleased at the feeling of Ri's back against his chest, her body fitting against his like a puzzle piece. He lightly ran his fingers along her arm as she slept, letting his lips leave a trail of soft kisses down the back of her neck. She stirred and made a soft noise of contentment, pressing herself against him as she opened her eyes.

She rolled over to face him, using the contours of his chest and neck as a map for her lips to find his. Ri sucked hungrily on Sherlock's lower lip, the heat of desire growing steadily into an ache that only he could soothe.

Sherlock tangled one hand in her hair as he pulled her closer to him, the other traveling down her bare back until he was gripping her buttock. His mouth moved away from hers, down her neck and across her chest until he reached the fullness of her breasts. His tongue teased her nipple until it stood at attention. There was a sudden, delightful rush of warm breath against her breast as Sherlock gasped when he felt Ri's hand wrap around his shaft, slowly gliding up and down.

Their lips met again, insistent with desire. Sherlock moved his hand from Ri's arse and slid it between her legs. He was surprised at how wet she was in response to his touch against the most sensitive area of her body.

"Do you have any more of those condoms," Ri murmured into his ear.

Reluctantly, Sherlock took his hands off her body as he reached into the nightstand. He quickly had the packet open and rolled the condom over his quivering cock. The need to feel her surrounding him was almost painful. He was about to shift his weight to roll her over when she straddled him, moaning in pleasure as she lowered herself onto him.

The hot, tight wetness of her sheath around him caused his brilliant mind to go blank. She was the only thing that existed to him in that moment.

Ri began to grind her hips, allowing him to thrust slowly in and out of her. His long fingers gripped her hips, pulling her down to him as he entered her.

Sherlock watched her face as she neared the much needed release of orgasm. Her breasts bounced up and down with each movement of her body. When the spasms overtook her, Ri arched her back and threw back her head, screaming his name in ecstasy.

Hearing her cry out his name at the height of her pleasure brought Sherlock to the edge. He no longer cared about anything but his own need. Before she could fully recover from that first orgasm, she could feel it building again as he plunged himself into her deeper and harder. They shuddered together in simultaneous release.

When the emptiness of orgasm faded from Sherlock's mind, he opened his eyes to find Ri still straddling him, holding him inside of her, with a satisfied smile on her face. Her chest still heaved as she struggled to catch her breath. The dim light from the hall threw shadows across her body like an abstract painting.

"You look beautiful like that," he told her, stroking her thighs as they lay against the sides of his abdomen.

Ri leaned down to kiss him gently. He wrapped his arms around her waist, drawing her body close to his. He reached down and threw the used condom in the bin.

They lay together in a contented stupor, lost in thought and each other. The sound of someone coming up the stairs broke them from their reverie.

"Shit," exclaimed Ri, a look of panic on her face. "It's John."

"I'll handle this," Sherlock assured her as he got out of bed. "Stay here."

He grabbed his dressing gown and put it on as he left the bedroom.

Ri could here John calling for Sherlock as he entered the flat. Please don't let him come back here, she thought.

Sherlock met John in the kitchen.

"You all right," John asked.

"Yup."

"Want to talk about it?"

"Nope."

"You gave Ri quite a fright," John said accusingly. "I think you hurt her. She had a fairly bad bruise on her chest."

Sherlock could feel a blush creep over his face.

"Did I? She didn't say anything," he said, trying to keep his voice casual.

"Speaking of Ri, where is she? I wanted to make sure she was okay too."

Sherlock reached for the kettle to make a cup of tea, giving himself a moment to compose his response.

"Bed, I think," he answered calmly, with a dismissive wave of his hand.

"Well, tell her I stopped by and to give me a call if she needs anything. I should really get back to Mary and the baby."

Sherlock busied himself making the tea, trying to give John the hint that his presence wasn't wanted.

"Right, I'm off," John said walking out the door.

Sherlock sank into his chair in the sitting room with his tea. He wondered why it was so important that John didn't know Ri was in his bed. It wasn't because he was ashamed of sleeping with her, and he didn't think she would mind if John knew. It slowly dawned on him that it was because he wanted what happened between them to be his. He wanted to be sure that Ri was his before he shared it with his friend.

Ri waited until she heard the door shut downstairs before she left the bedroom. She peered around the hall door cautiously, looking for Sherlock.

"Is he gone," she asked shyly.

"Yes, I don't think he suspected anything."

"Oh."

She sounds disappointed, Sherlock thought curiously.

"I was going to grab a shower," she said. "Care to join me?"

His tea was forgotten as he rose to follow her to the bathroom.
