"Ouch!"

"I told you!" Molly's laughter rang through 221b. A year to the day after the case that had finally brought her and Sherlock together, Molly stood in the living room of their flat, hands on her hips, this time, very much so pregnant for real this time, laughed as she watched Sherlock struggle into the prosthetic belly she once had to wear.

"How in God's name did you do this for three weeks?" He wore the belly over his dressing gown and pajamas, looking positively ridiculous. He winced at the pain of the heavy prosthetic, it pulled uncomfortably on his back and shoulders.

"You're the one who dragged the case out, besides, now I'm doing it for real, and I've still got four months to go!"

"Eugh, it bangs against the bladder every step," he grunted, waddling around the living room.

"You wanted to know what it felt like," Molly shrugged.

"You insisted!"

"Just wanted to share the joys of pregnancy with you, you started this after all."

He smirked at her. "I didn't hear you protesting at the time."

"I didn't at that," she agreed and leaned over, pressing a kiss to his lips.

He rested his hands on either side of the fake belly. "Well this is hardly the reality of pregnancy, I'd imagine the weights are the same, but it doesn't have half the side-affects you suffer with."

"It's to give you an idea-"

"Woohoo, Molly I brought you my back massager, and a couple videos you'd been wanting to borrow-" Mary and John entered 221b. One look at Sherlock, and both Watsons were trying desperately not to laugh.

Sherlock realized he still wore the prosthetic belly, then rolled his eyes, annoyed. "It's for an experiment!"
