A/N Hey My Lovelies!!! I was thinking today about how Sherlock has Danger Nights, and I realized that after everything that happened during S4 John would probably have Danger Nights too. So that's what this is. SMUT WARNING!!!! Enjoy<3

They were in the middle of dinner when John's phone rang.

He left the table to answer, leaving Sherlock to try and get little Rosie to eat her smashed peas. He wasn't gone that long, and Sherlock tried his best to contain the mess, but by the time he returned, there was green smudged everywhere.

Sherlock was grinning when he looked up at his boyfriend, laughing about Rosie's attempts at pouting. The joy left him as soon as his eyes met John's. They were dark and sad, his posture pulled tight. Sherlock stood, wiping the peas from his fingers and stepping slightly closer to the tense man.

"What's happened?" He whispered, not touching John, but letting him know that he was there if needed. John cleared his throat, wiping his nose and shrugging his shoulders. He looked at Sherlock, eyes wide and glassy.

"That was Harry." His voice was rough, but not in the way Sherlock liked hearing it. "She uh, she had some news." Sherlock's mind raced, trying to guess what happened to John's alcoholic sister this time. It had to be bad, it took a lot to rattle John like this.

"Do I need to call in favor from Mycroft?" John shook his head, taking a deep breath and closing his eyes tightly and pinching the bridge of his nose.

"M-My dad- my dad died." His voice wavered as his spoke, breaking Sherlock's heart. The detective watched as the man he loved struggled with his emotions. Sherlock didn't know a lot about John's past, but what he had been able to deduce wasn't pleasant. "I-I don't- I need-" John sighed, rubbing his hands over his face.

"Go take a hot shower, I will clean up out here." Sherlock offered, timidly reaching to touch John's cheek. He felt his boyfriend shy away from the contact at first, but the shorter man sighed and seemed to force himself to lean into the touch.

"Thank you." Sherlock smiled, fighting the urge to hug his lover. John clearly didn't want to be touched. He always got like that after talking about his father. That's what led Sherlock to believe that he had been abused.

Once John left, Sherlock pulled out his phone, sending a quick text before turning back to get Rosie cleaned up and ready.

Sherlock finished clearing the table and started packing Rosie's overnight bag. It wasn't the first time Gavin had taken her for the night, and she always loved it there. He made sure her nappy was clean and she had extra snacks and anything else she would need. He was just finishing up getting her ready when John finished his shower.

"What's going on? We got a case?" Sherlock spun around, his breath catching when his eyes landed on his lover, still dripping from the shower. He was wearing nothing but a towel tied low over his waist.

"No, I'm sending Rosie to Lestrade's for the night. I am under the impression that tonight is going to be a danger night, and I think it would be best if she weren't here for it." John looked devastated, clearly misunderstanding what Sherlock meant.

"How bad?" His voice was tight as he carefully walked towards Sherlock, holding out his arms to take Rosie. Sherlock handed off the baby and took John's face in his hands, pressing a soft kiss to hesitant lips.

"I am not the one in danger tonight John." He whispered, feeling the way John's jaw tensed at his words. "Don't be mad, at least not until Rosie is gone." John sighed and nodded, pulling out of Sherlock's grasp and going to sit in his chair, cooing at Rosie as he did.

John hated admitting that Sherlock was not the only one that had Danger Nights. He hated the fact that he had nights where he couldn't cope with his emotions. Sherlock knew how mad he was going to be when Lestrade picked up Rosie, but he wasn't going to apologize. He had seen John's danger nights, and he didn't want to expose the baby to that.

Lestrade arrived to pick up Rosie, his eyes full of questions. He didn't ask though, not after Sherlock gave him a look that advised against it.

Once Lestrade and Rosie were gone, Sherlock closed and locked the door, resting his forehead against the wood and waiting for John's temper to explode.

"Why did you do that?" John snapped, grabbing Sherlock roughly by the shoulder and spinning him around, the rage clear on his face.

"I told you John-"

"What gives you the right, to take my daughter away from me like that?" Sherlock flinched as John's voice rose.

"I-I thought-"

"You thought what Sherlock? You thought I would hurt her? You thought I would lose my grip on sanity and beat my baby?" John was fully shouting now, tugging at his still-damp hair and clearly resisting the urge to hit Sherlock.

"No, I know you would never-"

"I'm not him!" John froze, hands still in his hair. Sherlock watched the pain and realization flicker across his lover's face as his own words hit him. He stumbled back, shaking his head and blinking rapidly. "I-I'm not him." He whispered, hitting the back wall and sliding down, hands still tugging on his hair.

Sherlock walked up to the distressed man, kneeling in front of him. He stamped down the desire to touch John, giving him his space.

"All my life, I've fought against that man's memories, determined to become everything he wasn't. Now, I see I'm no better than him." Sherlock gave up fighting the urge to touch John and reached for him, shuffling closer and pushing John's leg's open enough to settle between them. He took John's face in his hands and kissed him softly.

"You are nothing like your father."

"You sent my daughter away because you were worried I would hurt her." Sherlock shook his head, blinking away tears.

"I know you would never hurt Rosie. Never in a million years would you lay a hand against that child. I sent her away because I was worried you would hurt yourself." John sobbed, crumbling in on himself. "I have seen your Danger Nights John, I know how they end, and I didn't want our- your daughter to see her father like that." Sherlock pulled John into his arms and held him tight against his chest, trying his best to comfort his lover.

John cried for a long while, clinging desperately to Sherlock. Once his breathing evened out, Sherlock helped him to his feet and led him to bed. He lay down and let the exhausted man tangle himself against him, holding him close and letting the comfortable silence fill the room.

"He used to drink." John's voice was rough with emotion, barely louder than a whisper as he traced patterns along Sherlock's skin. "He was the nicest guy you'd ever meet when he was sober. That's why no one questioned him. But then he'd come home and get a few scotches in him, and it was like he became someone else." John sighed, his fingers traced lower, swirling around Sherlock's belly button and causing the muscles to twitch. "He would always try to go for Harry after he finished with Mum. Most nights, I could stop him, turning his attention back to me until either I was unconscious or he passed out."

"No one deserves to be treated like that." Sherlock whispered, kissing John's temple and blinking away the tears.

"I hated him, have since I was a kid. But when I got that call from Harry tonight, all I felt was pain." John's voice cracked and Sherlock felt fresh tears fall from his lover's eyes. "After all he did to me, all I could think was that I wouldn't get to see him again. He will never get to meet Rosie." John pushed himself up on his elbow, staring down at Sherlock with tear-filled eyes. "He will never get to meet the man I love." He brushed his fingers along Sherlock's cheekbones, sending chills down the detective's spine. John leaned down, kissing Sherlock tenderly.

"I always assumed your parents would hate me." John laughed, continuing to press soft kisses to Sherlock's lips.

"Oh, they would have loathed you." John giggled, moving his lips to suck on Sherlock's ear lobe. "But I would have thoroughly enjoyed sneaking you into their bedroom and letting you fuck me senseless on their bed." Sherlock laughed breathlessly, rubbing his hands lightly along John's sides as the shorter man climbed onto his lap.

"You're a naughty boy, Doctor Watson. Let me guess, your parents are major homophobes?" John laughed, nodding his head as he captured Sherlock's lips with his own in a searing kiss. "I love you John." Sherlock whispered, a shiver running down his spine as John started undoing the dressing gown he was still wearing.

"I love you too Sherlock." John started moving his kisses down Sherlock's neck, pushing his shirt up and pulling it off.

"John?"

"Hmm?"

"I'm sorry I sent Rosie away without explaining it to you." John stopped moving, looking back up at Sherlock and smiling tightly.

"Don't apologize Love, you did the right thing. Besides, this way, you can have your way with me, no interruptions." John winked and bowed his head again, sucking a dark mark onto Sherlock's collarbone. "I-I want- no, I need you to take me tonight." Sherlock's eyes widened, and he felt his body start to react to John's words.

John never asked for Sherlock to top, preferring to be the one taking as opposed to being taken. They had only done it like that once before, and John found he disliked having to submit like that.

"A-Are you sure?" John nodded reaching for the bedside table and grabbing the lube and pressing it into Sherlock's hand. "Like this?" John nodded again, kissing Sherlock deeply to distract himself.

Sherlock slicked his hand thoroughly, still kissing John. He used his clean hand to guide John's hips up as high as they could go before slipping his lubed hand under his lover and massaging his tight entrance.

He took his time, making sure to be as thorough as he possibly could. He wanted John to enjoy this as much as possible.

Once John was trembling and begging for more, Sherlock carefully slid his fingers out and slicked his erection, hissing at the contact. He pushed John's shoulder so he was sitting upright and guided the shorter man down onto his erection.

John whined and gasped as Sherlock entered him, slowly sinking down until he was fully seated. They were both still while John adjusted to Sherlock's girth. Once he felt comfortable, Sherlock felt John start to move, pushing himself slowly before sinking back down, whining again. Sherlock moaned and gripped John's hips tightly, shifting his own hips slightly and changing the angle.

John cried out as Sherlock brushed against his prostate, and the sound sent a spark of arousal ripping through Sherlock's body. The detective reached up and wrapped his hand around John's erection, causing the other man's hips to stutter. Sherlock sat up, pulling John close and flipping them over, settling between his thighs and pushing back in. John moaned loudly as Sherlock instantly found his prostate, angling his hips so he hit it with every thrust.

"You're so beautiful- God John- beautiful. Brave. Strong." Sherlock punctuated each of his words with a firm thrust of his hips, John whimpering with each one. The shorter man's eyes were squeezed shut and his lips were parted, Sherlock was sure he had never seen a more gorgeous sight.

He reached between them and grasped John's leaking erection, pumping him in time with his hips.

Neither of them lasted much longer, calling each other's name as they climaxed. They held each other as they came off their post-orgasmic high, sharing soft kisses and whispered words.

Once they were cleaned off and settled in for the night, Sherlock gripped John's chin and pulled his face up so he could look at his eyes.

"John, you are nothing like your father. You are better in so many ways. You care, you're loving, you're kind. You would never lay a hand on someone you love and you would never hurt your daughter." John's eyes filled with tears as Sherlock spoke, his fears and insecurities fading away for now. "My life would not be half as good as it is if I didn't have you. You have saved me many times over."

"I've also hurt you-" Sherlock cut him off with a sweet kiss.

"Just as I have hurt you. We haven't had an easy road, but it has been worth every wound. I love you, John Watson." John sniffled, grinning and tucking his head against Sherlock's neck.

"I love you too, Sherlock." Sherlock smiled, feeling a spark of mischief rising in his chest.

"Are you planning on going to the funeral?"

"I guess so. Why?"

"I was just thinking, if you want, I could come with you. Then you can sneak me upstairs and fuck me on your parent's bed after the service." John laughed, swatting Sherlock's chest and snuggling closer.

Sherlock fell asleep to the feeling of John smiling against his neck.

Danger Night; averted.
