„Dobré ráno, Sherlocku!" 

I froze in an attempt to take a sip from my morning cup of tea. With a facial expression of total disbelief I slowly turned my head towards the person who just COULDN'T be my lover.

„WHAT?" I said in the same slow fashion.

„Dobré ráno.." he repeated.

„WHAT?"

„What what? I'm not gonna repeat that again. There's too much of that annoying R sound. RRRR.."

There was a moment of confused silence.

„You are learning Czech?" I asked at last, eyebrows rised as high as possible.

„Maybe..." John shrugged his shoulders. „It's pretty hard though..Well.. really hard actually.."

„How? I mean.. How did I not notice that?! You are not attending any lessons, you didn't buy any books..I would know that.." I frowned.

„Well.. I started just a few days back.. there's a Czech language option on Duolingo you know.."

„What's Duolingo?"

„Never heard about it?"

„Hmm obviously." I growled and finally took a sip of my neglected tea.

"Well it's an app, where you can learn different languages.. or..well..more like some basics." Explained John, settling onto chair on the opposite side of the table.

„Let me see." I said, leaning slightly fowards.

„Okay.. well.." mumbled John as he reached for the mobile phone in his pocket. „Here.." he said.

I took the phone and looked at the screen. „Why does it look like some stupid children's game?" I snorted.

„Well it's.. I don't really know... It's like for you to..remember it better I guess?"

„Hmmh.." 

I went through four different "lessons", without a single mistake, and came to a conclusion, that: „It's not exactly horrible..It's just totally useless when you actually want to learn the language."

„No it's noot!" opposed John.

„It's boring!"

„Is it?"

„Yes. It's incredibly tiring and a ridiculous waste of time."

„FINE," spat John, theatrically throwing his arms, "How should I learn the language then?"

„Well..I could teach you." I murmured.

A flash of surprise passed over John's face, but then he pouted thoughtfully.

„Mm.. yeah. Yeah you might actually."

I smiled.

„But how am I gonna make sure, that you're not teaching me some bollocks?"

„Why would I do that?" I frowned innocently.

John gave me the kind of "yeah, still don't believe you" look.

„I won't do that!! Really!"

„Okaaay, okay. I believe you." 

Later that day, or at 16:39 to be precise, I was rummaging through the disarranged variety of things in the table drawers to find a piece of chalk. At last I found it and holding it triumphantly I walked from the living room into my bedroom, where I happened to have an old-school chalkboard. I moved it to our living room and having approximately five minutes left to John's arrival I decided to make us some tea. At the time I filled the cups and added two sugars to one of them, there came a sound of footsteps on the staircase. 

"Joohn!! I exclaimed enthusiastically as I caught him right at the doorframe and leaned in for a quick, but quite passionate kiss. Then, holding him by his shoulders, I turned him around and backed him onto the armchair with words of „How was your day?" (even though I've already deduced, that he had 21 patients, two cups of coffee, a pretty miserable lunch in hospital canteen and a trivial argument with the receptionist). John looked kind of confused.

„What? I mean.. my day was eeh..fine.. but what has gotten into you?!"

I offered him a cuppa.

„Well I thought.. we may start with the lessons.."

"Oh! Okay." He smiled and glimpsed at the chalkboard.

"Didn't know you have this.." he stated.

„I do..," I smiled, "Soo.. where should we start?" I paused for a moment thinking.

„Well I know how to say "I love you",started John, smiling at the memory, "And I believe I know how to say eeh.. a boy, a girl, a man, a woman aand good morning.. You kind of stopped me there.."

„Right..Well let's test you then." I smiled mischievously and wrote KLUK on the board.

„A boy?"

„Quite right. Only this is just one way of saying it. You may also use.."

(I turned towards the chalkboard again and wrote) CHLAPEC, HOCH, CHLAPEČEK, KLUČÍK.. "There. Those are some other words for a boy.. though some of them would be used in a different context, it basically means the same thing."

„Chlapec?"

„Uh.. no.. It's not C as in "chair"..nor is it C like in Chloe... It's CH. They have their own letter for it. It's C and H together.." I made a pause. „No actually.. Let's start with something different." I mumbled as I wiped of the words written on chalkboard. I wrote a new one and turned back at John.

„Alphabet? Really?"

„You'll thank me later. So.. there's A." I wrote it. „And also a long version," I wrote a kind of comma on top. Á. „ It's the one you hear for example in ráno. You would read it as 'aaaa'"

John shivered mentally at the sound my baritone made saying that letter. I was aware of the fact that it sounds almost like a moan and there I got The idea. I turned at the chalkboard again so he could not see the smirk that crossed my face.

„There will be more letters with this long form. These are not named in the alphabet, only the hooked ones are. I'll get to that in a bit. Then there's B, that's normal, and C. There you also have-and there comes the hook- Č."

„As in chest?"

„Yes. And D has also this version with "hook": Ď." John nodded. „Then there's E. But also É, again the long version and then "hooked" Ě. There are some pretty complicated rules about using it, but I won't burden you with that now. Then there's F and G and H aand there comes the CH. Sounds a bit like.. laughter I guess? It's the kind of 'almost silent letter'. There are words as chobotnice, or chápat.."

„What do these mean?"

„Octopus and to understand "

„Yeah.. that's very random."

I shrugged my shoulders and wrote i and í. „You have a soft i and then a long í. Sound we have in a word bee for example. Then you have J. But they don't pronounce it like we do, it's sounds like Y in words like Yorkshire, yolk, or..well.. a simple yes actually."

„How do you say yes?"

„ANO. And no is NE."

„Okay.. easy..oh and okay?"

„Dobře."

„Uuuh no thanks." Laughed John.

„You can say okay too.. they use it in modern speech. Ookay.. so that was J, then there's K. They use K much more than us, because they write K where we write C a lot. For example cat, cast, clothes, cock, cum..- there's C, but they'd write K. I think it makes more sense. Now L, M, that's easy, and N has a version with hook, Ň as "gn" in cognac, which again has some difficulties, but we'll get to that later, and then O, which has a long version as (there I, again, very smugly enjoyed the sound) Ó."

John shifted awkwardly in his armchair. Meanwhile I, pretending not to notice, proceeded with writting P, Q (with comment, that there's just about five words in czech language that start with Q, even those few being taken from other languages) and then R.

„Yeah.. that's a hard one." Growled John pointing at the board.

„It's all about making very fast vibrations with your tongue."

There was a moment of silence.

„C'mon. Try it! Rrrrrr."

„Rrrr..r.. Rr.... how do you..?" Frowned John.

„Rrrrrrr. Watch." I said lowering my face towards him and opened my mouth wider.

„See the tongue? It must make a constant fast movement. Rrrrrrrrrrrrr.."

John licked his lips. I knew, that his train of thoughts was slowly deviating from the original direction. That was exactly what I wanted. My stomach swirled in excitement, but I kept my casual face and turned to write Ř.

„HOW are you supposed to read that?!"

  „Ř."

„R"

„No. It's Ř."

„Rz"

„Ř."

„Rrz."

„It's like R, but you move your jaws a bit closer together: Ř."

„Rr"

„Ř."

„This is impossible!" Groaned John, throwing his arms into the air in a dramatic fashion (for a second time that day)

„It's very much possible. Ř."

John now crossed said arms on his chest.

Impatient; I noted; Distracted. Slightly aroused.

„Let's just move on. What's after this Rz.. Rrz..whatever..stupid letter? S?"

I took my time answering. „No."

„No? Don't tell me there are some other versions of R!"

„No. We won't move on."

„Why? It's just a lette..!!" I didn't let him finish the sentence.

„Remind me who's the teacher."

John shrugged his shoulders. „You are I guess.."

„You guess?" I raised one eyebrow.

„Fine..You are."

„You are, Mister." I corrected and stepped closer.

„You are, Mister... if you insist."said doctor and made a soft laugh (subconsciously trying to somehow ease the tension I was creating; noted.) I smiled smugly. „Yes, I insist. I also insist that you don't laugh at your teacher."

„I wasn't laughing at y..." 

„Now try again.." I leaned just a few inches above him, so close, that I heard his slightly accelerated breathing.

„Ř."

„Rrz." Mumbled John.

I leaned even closer and rested my hands on the armchair

"Once again, please." My right hand now wandered teasingly close to his crotch and then I, almost as if by an accident, brushed my fingertips over his growing bulge.

„Rrzz"

„Again!" I growled.

„I can't!" moaned John. „It's too hard!"(pun intended)

„Too hard you say?" I raised my eyebrows.

Then I suddenly stood up and shrugged my shoulders. „Well..That's a pity. Today's class is dissolved then." I said, watching his face turn desperate.

„No please!" He croaked.

But I turned away and started wiping the board.

However, upon hearing a shuffle followed by the unmistakable sound of a zipper being pulled down, I turned back at John. His hand already got hold of his prick, but immediately stopped.

„One more thing, student." I barked. „Your homework."

„H..homework?" Shrieked John.

„No wanking. And definitely no coming." I growled with another smug smile.

John gave a desperate cry.

„You won't touch yourself before the upcoming lesson. You heard me, student?!"

„Yes, professor."

Chapter Text

„Dobré ráno!" I smiled over the table as I saw John walk into our kitchen.
His appearance was definitely more tired than yesterday.

„Mmmh.." growled John (sporting quite prominent bulge of neglected morning erection, I observed) and sat down, rubbing his face with his hands.

„Chceš kafe?" I asked and handed him a cup of unsweetened coffee. Of course I didn't have to ask, I already knew, that he would want one (that's why I made it), but I wanted to enjoy a bit of this..whatever it was...Poking around? Probably that.

„Ta." Mumbled John and took a sip.

„It's Friday isn't it?" I asked casually.

„Yes." 

At 16.40 I was sitting in my armchair, eyes fixed on the door. Deciding to make things a bit harder (pun, again, very much intended) for John I dressed in the tightest black trousers I had, caaasually forgetting to wear pants underneath and his favourite purple shirt (rolling up the sleeves and leaving three upper buttons opened). At 17:00 I frowned at my watch and then at the door. John was a man of habit and he came home before 5 o'clock 90% of the time. When he finally walked into the room it was 17:15.

„Hi!" He smiled, but then caught my face. „What?"

I stood up. „Do you know what time it is?"

„Eeh..quarter past five?" Answered John taking a quick glance at his wristwatch.

„Indeed Watson." I stepped closer. „You're late."

„I forgot my laptop in the office and had to go back." Said John shrugging his shoulders.

„Do you think it's acceptable to come late to a lesson?"

„We have the rest of the day. Also I don't recall us setting any time of.."

„Do I take it as a yes?" I growled, cutting him off middle sentence. John flushed under my piercing gaze. „This disobedience won't happen again, student." I said sharply and showed him in his armchair.

John, suddenly feeling a pang of "want to disobey" asked: „What if I do?"

I started writing letters on the board. „Well... then I might forget the modern society rules and use a physical form of punishment.."

John shifted. He was already sporting quite prominent arousal.

Interesting, I thought and added the knowledge into my "things to try with John in the future" list.

„But now it's time to start our lesson.. or it WAS twenty minutes ago." I gave John a disapproving look and then carried on with my writing. „So.. we were at Ř last time. There are words like dobře, přítel, or středa. In English good, friend and Wednesday. Now you try." I wrote the words and looked at him.

„Dobre..prr..pritel, streda?" John mumbled and licked his lips nervously.

„Not bad, Watson. Still can't hear the Ř though. Try saying Ž like in measure, and then add R to it. RŽ."

„Rž.." „Yeah. You're getting there. Now vibrate the tongue."

„Ržž.."

„More!"

„Rřžž. Oh! Did you hear that??" John's eyes widened with excitement.

„It's coming! Good job, student!" I smiled and moved in for a short peck on his lips. John jumped in surprise and grunted at the quick loss.

„Now try again."

„Rž..Rrř."

„Spit it out! Come on!"

„Rř. Ř!"

„Ooooh yess yes! Yes Watson!" I exclaimed and conjoined our lips in a passionate kiss. John groaned into my mouth and went to grab my neck. I pulled back before he could do so.

„That would be quite enough. Now try saying středa again."

„Stžeda. Strž..bollocks.."

„You see- you haven't won by managing it once. You'll have to practice a lot to expert it. For now let us move on. There's S and hooked version Š just like.. just like Sh in my name actually.

„Mmh.. I like that."

A very vivid memory of John moaning my name while I was rocking inside him made my cock twitch in arousal. Good. Let him see it. As if unconsciously, I rubbed my palm over my tented trousers and then proceeded with writing T and Ť. John shifted in his seat again. The urge to touch himself was clearly very strong.

„There's T and Ť."

„T?"

„Ť. Try to pronounce it as if you were saying tch in catch and then add a tiny bit more T to it. Make it a bit sharper."

„Ť. Is that right?" Huffed John. He was eyeing my bulge.

„Yes. Very well. There are words such as leť, or řiť.. There are not many of them, I'll get to that later. Then there's U. There are three versions of U." I wrote U, Ú and Ů. „There's a simple one, it's kind of choked- U, not "you" as in use, nor "a" as in under. It's just u, like you without y and o. Then there's a long version Ú (which is basically just making longer sound of U) and then there's Ů with a circle on top, which is pronounced exactly the same as Ú and you have to learn the grammar to know where to write the comma one and where to use the circle one. Okay, so that was U, now comes V and W, they don't really use W in Czech, they also don't use much of X, then there's Y. They call Y the "hard one" and they use it behind the "hard consonants" -H, CH, K, R, D, T, N. Soft I is used behind "soft consonants", being C, J, Ž, Š, Č, Ř, Ď, Ť, Ň. Personally I've always preferred the hard Y." I said and slid long fingers of my left hand under my half opened shirt.

„It's more pleasing to look at." I said in a deep voice.

John licked his lips and a small sound escaped his throat.

„Now there's Z. The very climax of the alphabet.." John breathed out shakily. „...If we talk about English. Czech language has also Ž. (Zh)"

„Ž." John obediently repeated.

„Very well, student. Now you've heard the whole alphabet. You deserve a reward for listening." I said as I came closer and then slowly lowered myself astride his legs (careful not to sit too close to his crotch).

My bulge was quite obscene now. As if it was to burst out of the too tight embrace of my trousers. John grunted desperately and his hips thrusted upward. My hand was immediately on his thigh holding him down.

„Shhh Shhh.. Don't try that. Now if you want to claim your reward you should show me if you were listening well..."

„I was! I was!" groaned John with a soft sob, fisting the armrests to prevent himself from any touching.

„Well then show me. How does the Czech alphabet  go?"

John was silent for a moment, trying to contain himself. Then with a shaky exhale he began.

„A..B..C"

My hand on his thigh started moving forward centimetre by centimetre

 „Č?"

Another centimetre.

„D.... oh fuck what was it..?"

My hand stopped.

„Ď! It's Ď!"

Proceeded with its movement. Simple game.

„What comes next?"

„E, F, G, H, CH, I, J, K..aah.." John moaned as my hand made its way to the base of his tented crotch.

„Yes.." I growled.

„L... M.. ooooh Sherl.." John threw his head back and thrusted up into my hand that has now softly squeezed his bulge.

„It's Mister, Watson." I growled and lifted my hand from it.

„'m sorry sir.. Mister.." gulped John.

I lowered my hand again.

„Continue."

John tried to remember where he had stopped.

„...N..Ň... O..P, Q.."

I undid the button on his trousers and began painstakingly slowly pulling the zip down.

„R..Ř.."

I gently rubbed him over his wet pants.

He was melting under my touch.

„S.. Š.. oooh fuck, fuck, fuck!"

„No swearing, Watson! School is not a pub!" I pulled at his pants revealing his dark flushed cock, that immediately sprang up to his belly.

„T, U....aaah no!" Yelped John when I retracted my hand.

„Wha..why???"

„What's after T?"

„U."

„Really?"

„Ooh Ť it's Ť!" Cried John.

„That's it for today's lesson. You will get your reward once you make no mistake."

Chapter Text

„When's the lesson today?" Asked John, trying to sound as casual as possible. There was however an unmistakable tinge of urgency in his voice.

I raised my head in disbelief.

„We're in the morgue. There's a corpse next to you and you're asking about lessons?"

„What lessons? You guys are learning something?" Said Molly standing between us with a curious look on her face.

„No I am teaching him."

„Yeah. I'm learning Czech."

„Didn't know you speak Czech, Sherlock." Said she surprised.

I just nodded and kept on with the examinations.

„So? When's the lesson?" Growled John.

He's really getting desperate, I realised.

„It's weekend. Your next lesson is on Monday."

„Are you serious?" Puffed John, clearly waiting for me to say "just kidding".

„Yes I am. You have time to practice."

On Sunday morning I woke up with a solid erection. I grinned smugly as I turned at my lover, still sleeping, facing away from me.

What if I just tease him a bit?

I shuffled closer and burrowed my nose in his clavicle, breathing in, savouring his smell and then gently mouthing at his neck.

I felt him stir and moved even closer, spreading one arm around him possessively.

I lazily found his arse with my prick and began to move gently.

„Sherlc'k..?" Slurred John half sleeping.

I thrusted a bit further. And groaned in answer.

„Sherlock what'r you.. wait is that..?"

„Mmmh maybe.." I rumbled and closed a fist around my cock, moving it in a kind of syncopation with my thrusts.

When I pinched his nipple with my free hand he wailed. „Stoop please! Please Sherlock!"

„You remember..your task..well... But I..didn't.. say..it'd be..an easy..o..one." With that I stifled my moan in his neck and painted his back with my release.

„You bastard." Grunted John, desperately trying to ignore his aching prick.

I climbed off the bed and put on some clothes.

„Get up, I'll make some tea. There's a murderer to catch!"

Chapter Text

„That was almost ten! Not a bad one, don't you think, John?"

„Not exactly something one would say about gruesome triple murder." Grunted John as he finally sat down after four days of "murderer hunting".

It was a Tuesday afternoon and yes, we had no lesson yesterday. I have to admit, that it was not exactly a part of my calculations, but I think it served to my advantage all the same. There was still a bit of adrenaline pumping through our veins from the wild chase after the culprit we undertook, as well as the good feeling of a job well done (since we did catch him), so I knew John would be surely amenable for me to make up for the cancelled lesson.

„It's three minutes to five.."

John looked up from his armchair.

My hands found one of the buttons on my shirt, playing with it casually. "However I feel like taking a shower now...I believe it is no problem, if today's lesson moves there?" I smiled, cocking my head.

John's breath hitched almost unnoticeably. He nodded. 

We were undressed in the matter of seconds and I pinned John against the bathroom wall, water hitting my back, snogging him senseless.

He moaned into my mouth and then grabbed a fistful of my wet hair.

My mind went nearly blank.

Shit.

Fuck.

Control.

I need to find the control again. „aah ALPHABET!"

„What?"

He noticed-I saw the twinkle of sudden understanding in his eyes.

Bugger.

„Tell me. The alphabet."I tried to sound as sharp as I could.

He smiled. „Of course, professor. It's A.."

Swiftly tugged the hair at the back of my neck.

A sigh escaped my throat.

His "B" was more of a grunt.

Because before I knew it, his body was crushing me against the tiles.

And it was so damn arousing.

Fuck.

His head was right behind my ear as he whispered: „C, Č.. then there's D.."

I felt his hard-on ever so slightly brushing my arse.

„Mmmh.. Ď? Am I right?" He knew he was.

This was his move.

Unexpected.

"Professor?" He murmured.

„Yes. Correct. Go..go on."

My voice was harsh and even though I really tried, it lost all of its usual confidence.

„E, F.."

His body was slowly swaying against mine with a dirtiness of a strip dancer. Where the hell did he learned that?!

„G.."

My cock twitched with every sensual lick of his erection.

„H, CH, I, J, K, L.."

New letter- new thrust. The simplicity of the act, his voice, his movements, the unheard rhythm- it made my head buzzing and almost incapable of noticing any mistake in his recitation.

„M.."

..His wet- and wait..lubricated? When did that happen?!- hand (the one that wasn't holding my hair) slid down and spread my buttocks.

„H..How dare you, student?! You think it's acceptable to.. to.. ,"

His finger slipped in shockingly fast.

„..AH!"

I clasped my hand over my mouth in shock.

That sound couldn't even be mine. It was at least an octave higher.

„Oh fuck, Sherlock that was the hottest thing I've ever heard." He growled and carefully worked in the second finger.

I was already on the verge of coming.

„Tell me. How do you feel about losing virginity of your pretty arsehole?"

I tried my best to speak over the suffocating power of my arousal.

„You..agh..haven't.. finished the alphabet, Watson."

He chuckled at that.

"Always so determined, are you?"

Third finger.

„Okay I was at M? N, Ň.." he withdrew his fingers. His second hand slid down so he was grabbing me around the hips from both sides.

I heard my heart beating loudly from an overwhelming excitement and anticipation..

„O..oooh fuck!" He was in with one smooth, slow thrust.

I gasped for air.

He felt much bigger from this point of experience.

We stilled for a bit, both catching our breaths, before he sighed: „P.." and moved halfway out.

„Q." he thrusted forward again, hitting my prostate with precision of a doctor (who, as a matter of fact, could break every bone in your body while naming them).

I moaned.

„R." Backwards, this time almost entirely out.

„Ř." Quick jab in. Thrust out.

„S." Thrust in. He was accelerating the speed and at this point confined himself in reciting only with thrust-ins.

„Š."

„T."

„Ť."

I had nothing to hold onto apart from the wet tiles, so I at least jerked myself with one hand I could spare (the other forearm was protecting me from hitting the wall too hard).

„Aah u.. U!" He was struggling to say letters and not just moan.

I wasn't really able to realise whether he's at O, or X anymore. My mind was blank.

„V. Fuck! W!"

„Ha..harder John!" I screamed.

He was shagging me like an animal.

And then bit my shoulder with a groan.

„X!" He was still clutching my skin in his teeth, groaning the letter into it.

At that point I forgot what is alphabet.

„Y!"

„Z!"

Long stripes of my cum painted the wall.

My hole clutched around John on its own and that's when he came too, filling my insides with his hot load.

He groaned something that could have been "fuck", but was not clear, for he was still biting me.

I bet it was bleeding. Not that I'd care about it.

He released my shoulder and kissed the spot gently.

„Sorry for that, love."

He slipped out of me and I turned at him.

„It's..No it was great." I probably blushed.

He kissed me lovingly. „Fuuck that was the best shag I ever had, Sherlock.."

„Yes. I think so too." 

We cleaned ourselves and got out before the water turned cold. Then John made us some tea and we finally sat down on our couch, my head nuzzling in his lap, while his hands played gently with my damp curls.

Everything became calm and silent.

It might've been an hour or so, before I realised what my brain, hazy with too much of arousal, didn't realise.

I bursted into low chuckle.

John's hand ceased to fondle my hair. „What's so funny?"

The way my body shaked in laughter was making him giggle too.

„We're so stupid, John."

„Hahah why?"

„Ž!"

„Oh.. oh bugger!"
