One day morning of 221B Baker Street.
Where John Watson is in the flat having his tea in the living room, reading his newspaper. Sherlock is in the kitchen working on his experiments looking through his microscope with goggles on his eyes. Sherlock will look at John's direction from time to time, aware of John not to know he is looking at him. He is waiting on the outcome of his experiment and that is observing his flatmates behavior.
Sherlock made a experiment two days ago and it has finished one hour ago before it was 7:00 am in the morning, he found his roommate is still asleep, he use this chance to put four drops of a vial experiment in the cup of tea. When John woke up and came downstairs, ready to make his tea in the morning.
He walk straight to the kitchen and he was stopped by Sherlock's arm from going further. Sherlock smiled and give him the cup of tea which there is a vial in it, John look at it suspiciously and before he take it, he ask some questions first.
"What's in it?" Sherlock fake a perfect frown, on his face when John said his sudden accusation.
"Tea" Sherlock said with a smile. John still look suspicious on the cup, Sherlock's holding on it.
"Nothing experiment or any drop of vial in my tea?"
"Why would I put that? I know you need to relax because this is your day off after all" Sherlock put innocent face as he could and a sincere smile that says please take it. John is somehow convinced and take the cup, he said thank you afterwards.
John feel a bit weird, there is a bad feeling when he drank the tea that Sherlock made for him but he paid no mind and continue reading his newspaper. He appreciate the effort when Sherlock make the tea for him and that is a sweet gesture for his day off.
Forty minutes has passed and he is watching a series in a telly and Sherlock is still in the kitchen with his experiments. He feels a sudden headache then it turns a bit dizzy and his visions are starting to blur.
Then John passed out.

When John wakes up, blinking his eyes to adjust his vision then he tried to sit up. He have felt something twitching above his head and another twitch behind his back. He put his hands on his head and felt something like it is his ear but it does not feel right then he realized the shape.
It's a Cat Ears on his Head.
John saw a blonde tail beside his thigh and he touch it, then he feels a sudden rush to his lower part.
It is Very Sensitive and it is a Cat Tail.
John could only think ONE person who is responsible of this and he did not hesitate to call the man who made him this, he is very angry and frustrated at the same time. So he shout the name through his vocal cords that could be heard downstairs and he thank god Mrs. Hudson is on her friends house this day.
"SHERLOCK HOLMES YOU BETTER COME HERE RIGHT NOW!"
Sherlock opened the door and look at John with a surprise in his facial expression but John did not buy it because he knew, he put SOMETHING in his TEA. He should have not accept that cup of tea, from this day onwards he would not accept any drinks that Sherlock is going to give him.
"Hello John, I know you are furious right now and ready to throw a punch in my face but I want to remind you that violence don't resolve anything"
"No, Sherlock I'm very sure throwing a hard punch in your face will lessen my anger towards you"
"Well. . . .let's all calm down, take a deep breath, John, that effect won't last long and I am proud that it works well, it will take 3 to 6 days for the effect to wear off" Sherlock said standing far away from John.
He wait John to calm down before he proceed to check the Cat ears and tail. John take a deep breathes to calm himself and relaxes, Sherlock walk closer to the bed and sit beside John examining the Cat ears and it twitched.
Sherlock looks at the Cat tail and he grabs it without warning, John yelps and it produce a very cute sound when he does it, he blushed and trying to get Sherlock's hands off of his tail because it is sensitive. Sherlock looked at John's blushing face and it looks so adorable, he did not release the tail from his hand even though John tries to pry his hands off but it only grips it.
John made a whimper when Sherlock does that and a tear forming on his baby blue eyes looking at Sherlock. His face is red up to his neck with a teary eye and his Cat ears bends down, he looks so cute.
Sherlock tried to restrain himself from ravishing John, right now, on his bed. John might not realize yet but he is laying on Sherlock's bed.
"Sher- Sherlock. . . Please. . . . Do-don't grip it, it's very se- sensitive" John said in a whimper, he feels helpless and the blood rush to his south is not making this situation any better. John does not like being vulnerable or showing his weakness in front of other people.
Sherlock knows that but seeing John like this, in a state of feeling embarassed. This is one of the fantasies that he have imagine on, what John would be look like when he have Cat ears and tail? Would he purr when he gives him pleasure? What colors that suit him the best, when he put a collar on John's pretty neck?
"John. . . . ." Sherlock leaned closer to John's personal space while rubbing his thumb on the tips of the tail. John put his both hands on Sherlock's shoulder to stop him from leaning any closer.
"St-sto-stop. . ." John feels his sensitive tail being touched on the tips makes him closed his legs, to hide his erections. His strenght are starting to fade when he feels the sudden pleasure goes through his body.
Sherlock use it as a advantage and leaned closer to John until there faces are 5 inches away from each other. John tried his best to push the shoulder but it was futile.
Sherlock remember, he have a hand cuffs that he puts under the bed, in case this kind of situation to happen. He released the tail and swiftly fast enough to cuff the hands on the bed board. John is surprised on the hand cuff.
"Where did you get that hand cuff ?"
John asks. Sherlock look up to John and smiled playfully.
"I stole it from Lestrade when he is annoying" He said and then he inspects the hand cuff is securely locked on the bed board.
"What are you trying to do, next?" John asks and Sherlock shrugs it, he proceed to lifts up the Jumper but failed because John does not want to cooperate.
"John, I need you to lift your back" Sherlock commands it.
"So, you could strip me bare" John glared at him.
"Obviously" Sherlock said it while rolled his eyes on a evident situation.
"Well, good luck with that" John scoffs and then Sherlock gets down from the bed, he look at John once and then he goes to the kitchen.
He opens the cabinet and get the scissors, it is sharp enough to cut the hideous Jumper and strip it off. That is what Sherlock thought in his mind and he go back to the room.
John stares at the scissor, on Sherlock's hand twirling the handle like he is ready to cut the clothes into two. John ready his legs to kick Sherlock on the crotch, if he needed to, just to stop him from cutting his Jumper or strip him naked.
"This is rubbish Sherlock, and you know that, So please stop on whatever you are going to do next" John tried his best to kick but it fails when Sherlock is taking advantage on their position.
"I only need to examine your body, to see where the tail is intact, that is all, John" Sherlock crawls on the bed again and make sure that John would not move his legs.
"Well, I assure you it's top on the buttocks where the tail is intact, I know more in human anatomy than you do, as my profession of being a Doctor!"
"I need my eyes to see, that your statement is true" Sherlock start to cut the Jumper into two and then he unbutton the blue shirt, leaving John feels chilled by the cold air touched on his skin. Then he lifts John's back in one hand then quickly yanked the trouser down, then take it off.
John was only left on his open shirt and a boxer shorts, his jumper already cut to pieces, and left on the floor like a pile of shredded cloth. He is still cuffed on the bed board and Sherlock is on top of him, eyeing his body like some kind of delicious meal on the table.
"Looks like there is a bit problem, I cannot see your back"
"Hope as well not, I don't think you can turn me on my back to face you" John smirk on that and he has confidence that Sherlock cannot do it.
And he was wrong.
John is on all fours and still on the bed, the hands still cuffed on the board. He regret to even be smug earlier that thinking the detective's brilliant mind cannot think of this tactic. He should have never underestimate on his pursue to see his intact tail.
"Don't be afraid, John, It is not like I would rape you. I only need to examine the tail of yours"
"Do it quickly! ! Get on with it then let me go afterwards"
"Fine. . . You do not have to be this grumpy"
John rolled his eyes at Sherlock, How can he be not grumpy when he is on all fours like an offering to his master, showing his ass in front of him. If Mrs. Hudson was here in the flat, if she accidentaly opens the door and saw him like that. She will even thought that they are having some kind of police with thief roleplay sex.
Sherlock gulps when he finally see the whole body of John, since he can't even have the slightest chance to see it. He even tried to walk in the bathroom and pretend he did not know John is taking a shower. Always failed because John always locked it.
He could only glance from time to time when John only on his green robe walking around the flat with a face towel on his shoulders. Glancing on the smooth legs, and the chest when the robes have a small opening.
Now he can see it whole except the boxers, the only thing that stand between him and the lovely ass. Sherlock slowly pulled the boxers down to the knees, he could feel John's back shuddered and tensed. He can see where the tail is intact just as what John said earlier.
Sherlock use his finger to trace John's back to the tail, John arch his back where he could feel the the fingers circling around the tail near his buttocks. He want to hide his erections since it would not go down, because of the stupid sensation lingering on his tail.
"Do you. . . . Really. . . Have to. . .pull my boxers, all the way down"
John who tried himself to ignore the erections and he could feel his tail, moving to hide his hole and crotch. According to what he is thinking.
"When is the last time you have a prostate exam" Sherlock found that interesting and quietly get the lube under the bed, not to let John be aware of that.
"Last summer, why?" John answered and hears something moved under the bed and ignore it.
"I am going to be your Doctor, for now" Sherlock opens the lube and put it some in his hands especially on his fingers. Make it slick and slippery for easier to put inside it.
"What?! Why?"
"Examination, remember"
