Chapter Ten - The Sign of Four

Ever since moving Edward into his nursery upstairs, Molly and Sherlock had been taking full advantage of having their bedroom to themselves. Most mornings now they engaged in a shagging session, most evenings too. This morning was no different.

Molly woke first, the sun having just barely risen. Usually she would let Sherlock sleep a bit longer, but today was a big day, not to mention that she was feeling rather aroused. After watching him for a few moments and drinking in the sight of his relaxed expression, one she seemed to only see now when he was asleep, she gently pulled the sheet away from his body.

His flaccid cock was lying on top of his thigh, positioned perfectly for her mouth. She hummed softly and slipped down the bed, before circling the tip with her tongue. He groaned and she watched with fascination as his cock twitched. Wrapping her hand around the base, she raised it and took the head into her mouth. He groaned again and she glanced up at him as she eased more of his length into her mouth.

"FUCK! MOLLY!" he growled.

She dragged her tongue against him before slipping him out of her mouth, and placing a kiss upon the very tip. He was now very hard. She could practically feel him pulsing in her hand. He breathed heavily, staring down at her.

"Come here," he said.

She smiled and slid her body up his. He grabbed her and rolled her beneath him.

"You are a menace in bed!" he declared.

She smiled cheekily at him. "How do you want me, big boy?" she asked.

He swallowed thickly before answering. "On your knees," he instructed, moving off of her.

Her smile widened as she did just that, leaning forward so that her arse was in the air. He took in a few breaths as he drank in the sight of her, so open and ready for him. He moved behind her and gave her folds a quick swipe with his tongue from bottom to top. She moaned loudly, her noises increasing when he teased at her clit with the very tip of his tongue. His cock was aching now, he needed to be inside of her. He situated himself on his knees and pressed his cock against her, sliding himself up and down, gathering her moisture.

"Ohhh please Sherlock! Please!" she whimpered, hating but also loving how he teased her.

He tapped the head against her clit, smiling when her legs shuddered.

"PLEASE!" she wailed.

He dragged the head up to her entrance and in one solid thrust, he filled her.

"Mmmmm! That's it!" she cried. "Give me all of that thick cock of yours Sherlock!"

He hissed out a curse, doing just that, thrusting into her again and again as deep as he could go. She leaned further forward, her face now nearly pressed into the mattress, her breasts swinging freely, as his hips smacked against the cheeks of her arse.

"Fuck, fuck, fuck!" she moaned into the sheets. She could feel him hitting her g-spot with every thrust, she was certain she was going to see stars when she came.

When he reached beneath her and began to stroke at her clit, she let out a wild cry. Her walls tightened around his cock. He tried to hold back, ride out her orgasm, but she was so impossibly tight around him that with one final thrust he came as well. He pressed his forehead against her back, groaning her name. After giving a final roll of his hips he slipped out of her and fell down onto the bed.

"Mmmm … that was truly glorious!" she said, dropping to her stomach, her legs stretched out behind her.

He made a noise of agreement. They laid there for several minutes, regaining their breath. He looked at her, noting that she had that freshly fucked glow about her, but there was also something else.

"What?" he asked her, noting the expression on her face.

She shook her head slightly. "I just-I can't believe it was a year ago that I gave birth to Edward, it doesn't seem possible."

He smiled. "I know."

They grew silent again.

"Go and shower," he told her. "I'll stay here, just in case he wakes."

"All right. Let's hope I can stand, let alone walk!" she said.

Sherlock chuckled, watching her slip off the bed before she toddled towards the bathroom. He rubbed his hands over his face, yawning loudly. After dropping his hands to the mattress he thought back to the day of their son's birth.

He'd certainly never expected to be in this situation, ever. For years he had spouted about love being a chemical defect, and a dangerous disadvantage, but then Molly had to come along and blow all that to the wind. His beautiful, darling Molly. Where would he be without her? Most likely not alive. He frowned as he thought of this, of the multiple times she had saved him. He owed her so much, far more than he could ever give her.

His thoughts returned to the present when she walked back into their bedroom, entirely naked and freshly showered. He pounced upon her, pulling her back down to the mattress. She let out a shriek, followed by a squeal before he silenced her with a passionate kiss. She smelled faintly of honey and lemons, his cock beginning to stir. He knew that if he didn't stop himself they would end up shagging again. Forcing himself, he pulled away from her. She peered up at him with wide eyes.

"Wow," she breathed out. "You better go and shower before I make you shag me again!" She gave his chest a push.

He chuckled and moved away from her.

Molly had completely outdone herself with preparations for Edward's first birthday celebration, wanting it to be perfect and adorable. Even in spite of the fact that Sherlock informed her that their son was still far too young to fully grasp what they were celebrating, or have any memory of it once he was older. She told Sherlock that she didn't care, and that the party was as much for them as it was for Edward.

Their flat was decorated with streamers, and balloons covered the floor, floating up into the air whenever someone moved around. Edward loved it, clapping his hands with glee, the bright colours catching his gaze.

All of their closest family and friends were there. The newlyweds, Lestrade and Meena, who could barely handle a minute separated from each other, let alone not have some part of their body touching the other person. The new parents, Mycroft and Anthea, they were sat on the sofa with their daughter, the Iceman having long ago melted. John and Mary were there as well, with their daughter Abigail who was occupying herself with a colouring book and some crayons while her parents were talking with Sherlock's Mum and Dad. They were keeping Edward entertained while Molly went into the kitchen to prepare dessert.

Sherlock found her there, putting the finishing touches on the cupcakes she'd made the day before.

"Molly, there's something I need to tell you."

She stopped what she was doing and looked up at him, his tone making her concerned. "What is it? What's wrong?"

"Nothing is wrong," he assured her. "I just think you should know about this before we continue with the party." He held his hand out to her.

She briefly glanced into the sitting room, making sure that everyone was preoccupied and that Edward was being well looked after. He was sat upon Mummy Holmes' lap, and she was pressing kisses to his rosy cheek, making him giggle with delight.

"Are you taking me somewhere?" Molly asked, as she slipped her hand into his.

"Our bedroom. I think it would be best if we're alone when I tell you this," he replied, leading her down the hall.

Her heart beat fast as they entered their room, and he shut the door behind them, cutting off the noises from the sitting room. He took both of her hands in his and stepped closer to her.

"Molly ... you're pregnant," he told her.

She gasped, her eyes filling with tears. He released her hands to cup her face, gently wiping away the few tears that had fallen.

"I had-I had a feeling that I was," she said shakily. "But I wasn't entirely certain, and with preparing for the party I never got a chance to take a pregnancy test. You're sure?"

He nodded. "Yes. But you can take a test if you want."

Her eyes sparkled. "Are you ... are you happy? We've never exactly discussed about having another child."

He slipped his arms around her. "I am very happy." He kissed her, brushing his nose against hers.

"Perhaps this time we'll have a girl," she said.

He hummed. "A mini-Molly. I like the thought of that."

She giggled. "I wish we could celebrate properly ... but I suppose that can wait until everyone has gone and Edward is asleep."

He kissed her again. "Yes, I suppose that can wait," he grumbled with a frown.

She reached behind him and pinched his bum. "Behave you, it is our son's first birthday."

He nodded and they shared in another kiss before leaving the bedroom.

A few minutes later everyone gathered into the kitchen, and Edward was sat in his highchair. As they all began to sing Happy Birthday to him he stared at each in turn, wide eyed and smiling, waving his fists about. Molly set one of the cupcakes in front of him, sans candle, just as the final line of the song was sung.

Sherlock stood behind her and slipped his arm around her waist, his hand splaying out across her stomach as she stepped back and leaned into him. Her heart swelled with love and happiness as she watched the little boy delve face first into the cupcake, smearing his cherubic cheeks with the frosting. She placed her hand on top of Sherlock's, her eyes filling with tears at the thought of the new adventure that awaited the three of them.
