John had stormed out the flat after an argument with Sherlock over one of his experiments; the man had no respect for privacy. He had stormed into John's room without bothering to knock, the doctor was wanking at the time, lucky the covers were over him. When he confronted the consulting detective he didn't see the big deal, he walked up to a flat and knocked. A gray haired man answered the door, "John, why are you here?"
"Can I come in?"
"Of course." Lestrade gestured him in.
"Fight with Sherlock over privacy." John said as the door closed behind him.
"Yeah, I imagine, you can stay here for the night if you like."
"Thanks, I will talk to him tomorrow." Lestrade brought the blonde some tea, "I can't even have a girlfriend because he drives them away."
"What exactly happened?" Lestrade asked.
"I…I was doing something private extremely private." John said not making eye contact.
"Right, and he didn't see the big deal… that is just Sherlock for you." The DI sat down, "You're the only person I know who can actually deal with the man."
"It isn't easy and it's just that my feelings have changed but he doesn't understand emotions."
"I am sure he understands to some point, he is still human." Lestrade said.
"Some days I doubt it." John said sipping his tea; John was getting the couch ready to sleep on. Lestrade heard John's phone ring for the 50th time tonight.
"Please, just tell him you're safe."
"No." Lestrade grabbed John's phone and the blonde went to take it from the detective, "Would you give me my phone?"
"No, not until you agree to tell him." Lestrade said, the two looked like kids fighting over a toy. Eventually they end up on the floor with Lestrade pinning John down, the two locked eyes and the cell phone being the last thing on their minds. If they had even been paying attention they heard the phone ring again, by that point they locked lips. John was starting to remove Lestrade's clothing as they kissed.
Sherlock was incessantly trying to get a hold of John; he finally chose to track his phone. He wanted John back home; he saw John was at Lestrade's flat. Sherlock quickly grabbed his coat and scarf, it was in walking distance.
John and Lestrade both laid there catching their breath, Lestrade laid next to John covering them with the sheet.
"How did we get to this from fighting over a phone?" John asked.
"I have no idea." Lestrade answered, "But apparently you really need it."
"Apparently." John remembered his phone; it had stopped ringing, "My phone's not going off anymore."
"Maybe he finally gave up." Lestrade said as his front door suddenly opened, he didn't have enough time to grab his robe before he heard a familiar voice.
"John!" both males in bed looked at each other, Sherlock saw clothes spread from the couch to the bedroom. Lestrade found some clothes and got dressed; he walked out to see Sherlock in shock. Lestrade picked up John's clothes and hand them to the doctor; John came out of the room to see a disheveled Sherlock.
"What… what… this isn't you." Sherlock finally said to John, he was at a loss for words and left the flat. Lestrade and John looked at each other.
"I am sorry." John said to Lestrade grabbing his stuff and going after Sherlock.
Sherlock was now at the flat, he was waiting to see if John followed, he heard the door open and smiled. John came up the steps and looked at Sherlock.
"What the hell was that?!" John all but yelled.
"That was me proving a point." Sherlock said he walked up to John, he cupped John face bringing him in for kiss. The blond gave into the kiss and only broke away to get some air, "Why would you have sex with Lestrade when you want me?"
"I don't know, I don't remember what happened."
"Good." Sherlock dragged John to his bedroom closing the door behind them.
