Disclaimer: I own nothing of Sherlock BBC and this story is loosely based on Big, a Korean Drama

"I hated you. I really did because you were the perfect and convenient excuse to blame for my unhappy childhood. Looking back, it must be hard for you too. Being smothered by Mummy like that. No wonder you left and didn't want to come back. When I was young, I wanted to be you and when I really did 'become' you, I could now understand that those thoughts only acted as my form of escape. The truth was I never really wanted to be you. But so was the old Molly Hooper, she was a disguise. Mousy Molly was not the real me. That was just a mask that I willingly wore throughout my entire life. After the mask was removed, I was lost; could not find myself. Then I found out you could be whoever you wanted to be so long you follow your heart..."

"What are you doing here, Irene Adler? Step away from Molly." John's loud voice attracted attention from the nurse in-charge.

"Anything wrong here?" Molly could just read the nurse's mind, wondering if she should call the police or something like that.

"Nothing wrong here. Nurse..." Molly looked at the nametag, "Hanson. Family issues, you know" and gave her a wink.

"Even so, do lower your voices." Then the nurse left the ward, trying to hide the slight blush on her cheeks.

"Family?" John turned and looked outside before continuing. "Just because you are Irene Adler did not mean you could talk your way through things here. Molly was in no way a threat between you and Sherlock so leave now."

"John, did Sherlock not tell you? I AM her sister, long-lost due to unfortunate circumstances but now I'm back." Molly then reached out to touch her 'sister's' face but was intercepted by Mary's hand.

"You would let Molly recuperate in peace and when she woke up, you could then reunite with her if she wanted you back in her life and you would respect her wishes regardless." Mary placed herself between Irene Adler and Molly and spoke with conviction. Nothing less expected from the former assassin.

"My, how protective you two are. Molly must be so lucky to have such good friends by her side." John scoffed and replied "Like you would know."

Suddenly, Sherlock stepped into the ward. Molly frowned, thinking why he was doing here.

"Sherlock, just in time. Accompany Irene Adler because she is leaving now." John announced. Sherlock looked around the room, gathering information about what had happened and did what John asked.

"Well, it seemed that visitation hours are over for you. Let's go then." He grabbed Molly's arm and left.

"How is your progress on Colonel Moran's case? I believe he has gone mental after Jim killed himself, making him all the more so dangerous." Once out of the hospital, Molly quietly pulled her arm out of Sherlock's hold and walked on.

"Mycroft is still collecting intel as we speak and as always, London would be ready for whatever that might come ." Molly nodded then turned to Sherlock. "Shall we go back to Baker Street?" Reading the signs, he agreed.

Upon arrival of the flat, Sherlock took off his coat and scarf. "How about sex? I know you lust after Irene's body and I wanted to know how it felt like to be your one-time lover. It's a win-win situation. You know I want you and I could tell you want her. Like it or not, it's normal to have desires, Sherlock. You are a human after all. Just go with it. Trust me."

Like what Molly used to dream of, she grabbed his collar and their lips met. Molly's hands went up to run her fingers through Sherlock's curls. It felt so good. Soon all their clothes were removed and they made it to his room. Molly pushed Sherlock to lie on his back on the bed and climbed over him, raining kisses on his forehead, nose and throat.

"You smelled so good, Sherlock. It actually smelled familiar." Nibbling his ivory neck, she inhaled his scent like it was drugs for her. Molly couldn't help herself and marked him. Sherlock froze. Afraid that she had displeased him, Molly kissed the bite and apologized clumsy. "Sorry! I would not do that again if you did not like it."

"Just continue." Sherlock commanded. Molly carried on and explored him, touching his smooth chest and flat stomach before moving further down south until she reached the Holy Grail, already up and ready. Sherlock in the meanwhile ran his hands up and down of Molly's back like he was fondling with an experiment for he knew very well the contours of Irene Adler's body yet this person was actually Molly. It felt different despite being the same body he had sex with before yet Sherlock could not pinpoint what was different. He loathed not knowing.

Lifting Molly by the waist, Sherlock penetrated her in one move and both gasped in delight from the tight contact. He placed his hands on her bottom and rocked upwards. With her hands on Sherlock's chest for support, Molly began to ride him. Like driving through a dark tunnel, they could now see the light and proceed to drive even faster in a desperate attempt to reach the end quickly.

Coming out of the tunnel, the light momentarily blinded them as man and woman found their release. The world went upside down then back to its rightful place. Molly sighed internally with an air of satisfaction. So this was how it felt like then. Molly resolutely did not want to feel any guilt towards Sherlock for using him to check one item off her list so to speak. They did use each other but it was also of mutual consent. Pushing herself off Sherlock, Molly left the room to search for her clothes. She should not stay here for too long.

"Thank you, Sherlock." His face was unreadable. Perhaps he hated himself for being so weak to succumb to sexual urges but it was none of Molly's business. Sherlock needed to deal with it on his own. Come to think about it, the smell of him up close was familiar to Molly for some reason. It smelled like...a thought flashed through her mind but it was too quick for Molly to catch it. Now that the deed was done and over, maybe she should just stop thinking about it.

During those two years, each time Sherlock went to Molly's house which functioned as his bolt-hole, he would naturally take her bedroom while she uses the spare one. Actually, it was more like Sherlock decided without consulting Molly but he knew she would have no comments about it anyway.

Initially he was not used to lying in her bed then Sherlock realised because it smelled like Molly, her almond-flavoured body wash to be precise. That was why it was keeping him awake in the night. If Sherlock could do without rest, he would gladly accept that but biologically, it would be impossible.

Therefore, to be able to sleep in Molly's bed, Sherlock showered using her body wash. He deduced that by doing so, the smell would no longer distract him thus enabling him to rest properly. It sounded ridiculous but for the moment necessary. Now, long back from death, Sherlock still used that same brand because somehow he needed it to go to sleep however redundant it was, he reasoned. Creatures of habits, all humans are but it did not mean that Sherlock did not hate this absurd habit of his, just that it seemed harder to kick out of it than drugs.

Author's note: If you read my other story, I said before that I probably would not write anymore sex scenes but I'm obviously not a woman of my word. I just sincerely hoped that I did not just steer my story into a zone weirder than it already was!
