John and Sherlock had been together for three years now. When they first got together, John had no idea Sherlock was trans until he told him on one of their dates. John was very surprised, but didn't mind. He felt something with Sherlock and was going to keep it. They got more sexual as their relationship grew, but John wasn't allowed to touch Sherlock's lower region, and he was alright with that. He got more pleasure than Sherlock and he always wanted to return the pleasure to Sherlock, but he always turned it down. What Sherlock did while John was at work when he needed some attention, he'd lay out on their bed and finger himself. He always got off thinking about John, picking out that one specific folder in his mind palace. Sherlock noticed there was something up with John after their third anniversary. He started acting weird and was always playing with something in his pocket, so Sherlock set to work and went throw all of John's trousers, finally finding the ring in one of his socks. It meant a lot to Sherlock to see that John was still going to propose to him even though they've never had sex. John hasn't even seen Sherlock completly naked and yet, he still wants to marry him. Sherlock thought about it for days. Him and John have been together three years, it was time to stop holding back and let John pleasure Sherlock.

"Hey, John?" Sherlock asked, leaning on the bathroom door frame. 

John looked at Sherlock throught the mirror while he brushed his teeth.

"I was thinking," Sherlock looked at the floor. "We should have sex."

John almost choked on his toothpaste. He spit it out and turned to Sherlock, wiping his mouth with the back of his hand. "Are you sure? I've been fine with out it."

"I'm sure. We've been together three years and I think we should do it."

John walked to Sherlock. He smiled with his lips and cupped Sherlock's cheeks, bringing him down for a kiss. "Are you positive?" John asked.

Sherlock nodded. "I bought condoms while I was at Tesco." he kissed John.

John kissed back and directed them out of the bathroom amd into their room, turning the light on and pushing Sherlock onto the bed.

Sherlock reached under the bed and pulled a box of condoms out, setting them on the bedside table.

John crawled on top of Sherlock and gently kissed his neck as he unbuttoned his shirt, sliding it off of him once he was finished. He felt Sherlock tense under him once he reached for the buttons on his trousers. "We don't have to do this, love." John said, looking at Sherlock.

Sherlock shook his head. "I want to do this." he started muttering things to himself as he lifted John's shirt over his head.

"Okay," John said softly and kissed Sherlock again.

Sherlock eagerly kissed back and reached for John's shorts, pulling them down and waited for John to tale them completly off. Once he did, Sherlock pulled him back into a kiss and ran his hand over the buldge in John's red pants. 

John moaned against Sherlock's lips and Sherlock bit his lip, smirking and looking up at John. John sat back on his heels and undid Sherlock's trousers, pulling them off of him and tossing them onto the floor. He looked over Sherlock. The binder was off and the only thing still on Sherlock were his boxers. John didn't think he could be any more perfect.

"Come on John." Sherlock whined, rubbing his legs together.

John smirked and spread Sherlock's legs, getting in between them and kissing Sherlock again. Sherlock grabbed John's hand and directed down his body, slipping it under the waste band of his boxers.

"You shaved." John said.

Sherlock nodded. "I wanted tonight to be perfect."

John pecked Sherlock's lips. "It already is."

Sherlock smiled and gasped silently as John's fingers slid in between his folds.

"You're so wet." John said, rubbing his thumb over the clit.

Sherlock moaned and arched his back. "I've been thinking about you all day."

"Have you?" John asked and kept rubbing his thumb over the clit.

Sherlock moaned louder and nodded. "I-I had an orgasm while you at work, thinking about tonight."

"So you touched yourself today?" John asked and slipped a finger into Sherlock.

Sherlock bucked his hips and groaned. "Yeah. I couldn't hold it in any more." he inhaled a deep breath. "I got one of your jumpers, sat in your chair, and got off thinking about you."

John growled and bit Sherlock's neck, slowly starting to thrust his finger.

"God!" Sherlock moaned. "Please J-john! Just fuck me!"

John pulled Sherlock's boxers off and took his own pants off. He got a condom from the box on the bed side table and rolled it on, lining up with Sherlock. The tip barely touched and Sherlock went off his rocker. It was easy for John to push in and they both moaned once his was fully in.

"You're so tight." John moaned, pulling back then pushing back in.

Sherlock clawed John's back with his dull nails, trying to grasp onto something as John started to pick up his pace. He had one hand gripping the sheets tightly and the the other in John's hair, lightly tugging at it.

It wasn't long before Sherlock was screaming John's name, clentching around him. John kept going and Sherlock was over filling with pleasure, his second orgasm building up quickly.

After the third orgasm, John filled the condom and pulled out. He smirked and the limp, flushed Sherlock laying before him.

"How was it?" John asked, getting off the bed and taking to condom off, tying it and tossing it into the bathroom bin.

"Thatwasamazing." Sherlock barely said in a whisper.

John chuckled. "What'd you say?" he asked and turned the bedroom light off.

"That...was...amazing." he panted.

John got in bed with Sherlock and spooned him. He left light kisses on Sherlock's neck and back.

Sherlock shifted a little bit until he felt John's cock rub against him.

"You want to go again?" John asked.

Sherlock nodded and pushed John on his back, climbing on top of him. He leaned down and started to kiss John's neck. "This why I didn't want to have sex," Sherlock whispered into John's ear, "I knew once I felt you, I'd want more, and I want more." he nibbed John's ear and sunk down onto him.
