"And stay out of my bedroom," Sherlock warned John, walking into his room and shutting the door. John peered at the door a moment, then shrugged his shoulders and walked toward the hallway.

The next second, Sherlock's door had opened, and a slight figure in a white shirt padded out. She hadn't seen him yet, and lightly skipped her way to the kitchen.

Only when she was nearly at the kitchen did she notice the figure standing frozen in shock to her left.

"Oh!" Molly gave a small squeal of surprise, her hands immediately pulling the bottom of her shirt down to hide her legs, trying to cover as much of herself as possible.

"John! What a surprise!" She squeaked, slowly backing her way to the bedroom. "I'll be with you in just a titch!"

A second later, she had disappeared into the doorway, leaving John standing there with his mouth wide open. Molly...and Sherlock?!

He could hear the sound of a female voice shouting, and then a lower, gruff voice replying back calmly. He couldn't hear what they were saying though.

He walked up to the bedroom door and pressed his ear against it.

"Sherlock! You never told me John was here!" He could hear Molly hiss over the sound of slight splashing.

"Oh, he'll know we're together soon enough anyway. Don't bother blushing, it's completely useless. It was simply a matter of time."

Molly's voice became softer, and he could no longer hear so well.

Then Sherlock's deep laughter and then a large splash, like a large object had fallen into the water.

Sputtering, and an indignant voice.

"Sherlock! You always do this! You're going to be late!"

His eyes widened. They wouldn't. Not while he was just outside...would they?

He got his answer when he heard giggling and then soft moaning.

Now HE was blushing. He quickly backed away from the door and sat down in Sherlock's chair, preparing for the long wait ahead.

Twenty minutes later, Sherlock swiftly opened the door and walked out a step, buttoning the top button of his suit. He looked back into the bedroom, then scowled.

Walking back in, he dragged a bundle of white t-shirt and too-large jeans out despite her protests and her insistence that Sherlock, my hair is all wet, it'll stain your suit.

He grabbed her hand and dragged her in front of John, who was still sitting in Sherlock's chair, one eyebrow raised in amusement. Sherlock and Molly. Who would've guessed? And it seemed Sherlock was most definitely, as his brother had suggested, not a virgin anymore.

"Hi, John." Molly peered out shyly from behind Sherlock, her eyes downcast and her hands clinging to Sherlock's suit.

Sherlock pulled Molly out from behind him, leaning down and tilting her chin up, his hands controlling her head. He crushed his lips to hers, ignoring her squeals of protest, and unfortunately for poor Molly, giving John an eyeful.

Ten seconds later, he ended the kiss, turning to face John.

"I assume you have questions?"

John shook his head furiously. He wouldn't ask them even if he had any. He had seen enough.

"Come on, then. Let's go." He grabbed his Belstaff, not to take it with him as John suspected for a moment, but to drape it around Molly's shoulders.

As he stood and awkwardly shuffled his feet, Molly seemed to forget her embarrassment.

"Stay safe, okay? I love you." She leaned up on her tiptoes, pressing a chaste kiss to his lips.

"I love you too," he replied, pulling her close into a hug so tight it seemed he wanted to rub her into himself.

John stood there, not knowing what to do.

When they broke apart a second later, Sherlock glanced at him.

"Come on."

He nodded to Molly, hurrying after Sherlock out the door, but his mind was no longer on Magnussen.

Wait till he told Mary about this.
