I'll be grateful if you leave some reviews and let me know if you like the story! From this chapter on, the story will focus wholly on Drarry and show the shift in their relation. Enjoy!

The next day Harry was sitting in Great Hall, nibbling at his piece of fried chicken and mashed potatoes. After all day of classes he was exhausted and could dream only about a soft pillow and his bed. There was one thing that made the day better though. During the potions, Snape had walked by his desk and had pushed Harry's vial off the edge, making it fall and crush all over the floor. No one even noticed that it had been Snape's doing, but every head in the class had turned towards him. He had stared at the Potions Master confused but Snape only hissed "Detention. Tomorrow, eight o'clock" through clenched teeth. And so Harry had felt a spark of excitement travelling down his spine.

He took a bite of the chicken and chewed on it, thinking about tomorrow. Today was the fourth day. That meant tomorrow he would be able to come. Finally. With all these memories he had every night of Snape and Malfoy he could barely stop himself from reaching to his pants and getting himself off. It was so frustrating that he had decided the previous day that if Snape doesn't make any suggestion then the first thing he would do in the morning of the fifth day would be wanking himself until he paints the whole room white.

But Snape had told him to come over. Again, Harry shivered at the thought.

He took a gulp of pumpkin juice and stood up, making his way to the dormitory, hoping for tomorrow to come faster.

After he woke up the next day, his first thought was that he can't not wait until evening, but remembering Snape's glare and Malfoy's surprisingly strong hand spanking him hard he quickly dropped the idea of a good morning wank. Instead he went to the bathroom and took a very cold shower.

The classes were passing ridiculously slowly and by the dinner he was jumping at every little brush whenever someone or something touched his body.

Sitting in Great Hall with Hermione and Ron, he wasn't even pretending to be listening. He stuffed his mouth with food, trying to chew on it quicker, taking a sip of water to make it easier to swallow.

"Um, Harry?" Hermione's voice reached his ear and he looked up at his friends.

"Mhm?" he managed, his mouth still full.

"Are you in a rush?"

"You forgot?" Ron asked "He has detention with Snape tonight."

Harry finally swallowed the food and nodded "Yeah" he said, reaching for some juice.

"Oh, so that's why you're eating like crazy? But the detention is at eight" she checked her watch.

"Mhm. I can't wait" Harry replied without much thinking and when he realized what he had just said he quickly glanced at his friends who were glaring at him in disbelief "I-I mean, for this to end. I can't wait when the detention is over."

Ron relaxed immediately and nodded in agreement. Hermione looked still a bit confused but gave him a reassuring smile.

"You'll be fine, Harry" she said.

I hope for more that fine, he thought, but returned the smile "Thanks guys" he took a sip of his juice "Guess I should go."

"Already? You still have half an hour."

"Um, yeah, but I want to go to the bathroom first" he mumbled and stood up "See you later, guys, alright?"

"Yeah, sure mate" Ron answered, nodding.

"Good luck, Harry" Hermione said, waving at him sympathetically.

Harry left Great Hall full of students and made his way straight to the dungeons. He didn't really need to go to the bathroom, he just couldn't wait any minute longer or else he would explode from excitement.

He reached Snape's office and after a moment of hesitation knocked.

"Enter" a cold voice came from inside.

Harry took a deep breath and pushed the door open.

Snape was sitting behind his desk, grading the papers of the first years. He looked up at the entrance, then at his watch and back to the essays.

"You're early, Potter."

Harry walked in and closed the door behind his back.

"I-I know, professor. I just thought…" he paused, not knowing what excuse he should come up with.

"Doesn't matter, Potter. You're already here" he said, putting away the parchments "Come" he ordered and Harry hoped he would hear this command at least one more time that evening.

He moved closer until he stood right in front of the desk. Snape looked him up and down and pushed himself slightly away from the desk, remaining in his chair. He nodded at Harry to come up.

He looked at the man hesitantly but eventually rounded the desk and stopped few inches away from Snape. The professor opened his legs a bit, making place for Harry.

"On your knees."

Harry gulped but complied almost immediately, dropping to his knees and positioning himself between the lean but slightly muscled tights. He then looked up to find the black eyes staring at him intensely.

The Potions Master quirked an eyebrow in a silent expression of impatience and so Harry slowly raised his hands to the man's belts and opened his trousers.

When he took the soft cock out he glanced up again, asking for permission or further orders.

"Do you want it, Potter?" Snape asked lowly.

Without taking his eyes off the black pupils, Harry nodded "Y-yes, professor."

"Then get to work."

His whole face flushed bright red but nevertheless he parted his lips and took Snape's prick into his mouth.

He sucked at the head, teasing it with his tongue and then started to bob his head up and down. A large hand tangled in his hair but let him continue his steady movements.

He kept bobbing his head on the shaft and until several minutes the hand in his hair tightened and he took it as his cue to speed up. Not even a minute later he heard Snape grunt and then his throat was filled with a shot of hot cum.

He swallowed, careful not to spill any on his clothes. Once he was done, he looked up at Snape. The Potions Master was observing him with a mysterious smirk, panting slightly from his orgasm.

Orgasm, Harry thought. Snape had an orgasm in his presence. He had an orgasm because of him. Jesus, he would never get used to it.

Harry stayed on his knees, watching the spent cock until the professor tugged it back into his trousers.

"Having fun without me?" an amused voice came from the entrance and Harry's heart stopped for a second, afraid that they were caught.

He turned his head and saw Malfoy, the door closed behind him, walking towards them, his every movement stunningly elegant.

"Mr. Potter arrived on his detention early" Snape answered "I thought we might as well as use his eagerness while waiting."

"You mean his pretty mouth" Malfoy flashed a grin at both of them and Snape answered with an equally dark smirk.

"Indeed" he said, then looked at Harry "Stand up, Potter."

The boy raised from his knees obediently. He more felt than saw Malfoy approach him, until he was turned to face him.

The blond gave him a predatory smirk and reached his hands behind Harry. Harry gasped in surprise as Malfoy slid his hands under the waistband of this trousers and under his pants, and whimpered when the blond squeezed both of his buttocks.

"Still sore, Potter?" Malfoy asked.

In response Harry's face got all red in embarrassment.

"Want to tell me something, Draco?" Snape asked curiously.

Malfoy bared his perfectly white teeth "A little spanking on the Astronomy tower" he said, kneading the round cheeks.

Snape hummed approvingly "Let's see."

Malfoy grinned at their professor. He took his hands out of Harry's trousers and brought them to his front, undoing the fly. Slowly he slid Harry's trousers along with underwear to his mid-thighs, all the time looking into the green pupils.

Harry stared back, unable to look away, feeling his ears growing hot when his bare bottom was met with the cool air of the dungeon room. Then Malfoy caught the hem of his shirt and lifted it, exposing his arse completely.

"Quite a sight, aren't you, Potter" Snape murmured "Can you even sit?"

"Oh, now it's fine" Malfoy answered for him "You should have seen his arse two days ago, professor. On bloody fire."

"Well, let's see it now" the older wizard offered and Malfoy responded with a wicked smile.

At that Harry's heart stopped beating and his eyes widened "N-no! Not again!" he yelled, trying to step back from Malfoy but the Slytherin held him securely "Please, not again!"

Malfoy sighed "Calm down, Potter" he slid his hands back on his arse to palm the pale cheeks but Harry just shook his head. Malfoy leaned down so that there were inches keeping them apart, and looked Harry straight in the eyes. When he spoke, his voice was low and gentle "Just a little bit. I promise."

Harry didn't know how, but he was drawn to that voice as if it hypnotized him. He stared into the grey eyes for a long moment until he finally felt one of the hands on his butt disappear only to be back seconds later with a loud smack.

He drew in a sharp breath and fell slightly forward, pushing into Malfoy's chest. The blond didn't seem to mind as he raised his hand and gave another hard spank, making Harry gasp in pain and hold onto Malfoy, twisting his hands in the other's shirt.

With the next strike, Harry let out a helpless whine and let his head fall forward, his forehead resting against Malfoy's chest. Another smack and he shot his head back up, right in front of Malfoy's, and moaned, squirming against the Slytherin's body.

Harry opened his eyes and immediately was met with grey pupils watching him intensely. He let out a ragged breath and then felt a sharp burn when one hand slapped his right butt cheek. He panted, his hot breath ghosting over Malfoy's lips, their eyes still locked.

He prepared himself for the next blow, but it didn't come. Instead, Malfoy stroke his sore buttocks, caressing them gently with his long fingers.

Just when Harry started to relax, Malfoy took his hands back and applied one more hard smack.

Harry's body jerked and he half cried out, half moaned, right in front of the Slytherin's face, shutting his eyes.

When he reopened them, Malfoy was still watching him closely. His swift hands came back to stroking the sore, now probably dark pink or already red arse cheeks.

Harry was panting for a couple of moments, trying to catch his breath. Malfoy tore his gaze away from him and turned it to Snape, who was still sitting comfortably in his chair.

"Perfectly pink, isn't it?" he crooked a smile at the professor.

Snape nodded slowly "What else did the two of you do?"

"Just fooling around a bit" Malfoy said, shrugging.

"Meaning?"

Malfoy turned his gaze back to Harry's red face "Why don't you tell him, Potter?" he asked with a smug smile and slowly turned Harry around so that he was facing Snape.

"Um, I-I…I sucked him off" he mumbled sheepishly "A-and Malfoy…he, um, he jerked me off."

Snape arched his eyebrow questioningly "Oh?"

"I didn't come, sir" he rushed with an explanation "Malfoy didn't let me cum and I didn't."

"Indeed?" Snape hummed, watching Harry carefully "Did you want to come?"

Harry gulped. He thought about the feeling of Malfoy's hand on his cock, moving slowly up and down. A moan escaped his lips at that memory.

"Yeah" he admitted in a pant "I wanted to, so badly."

"Good boy" Snape replied, then patted his knee with one hand "Now come here."

Harry hesitated for no longer than a second and took two, three steps, finally stopping in front of Snape. The man grabbed Harry's wrist and maneuvered him onto his lap.

Harry gasped when his bare, freshly spanked bum landed on the rough fabric. It turned into a whimper, when Snape let his hands fall on Harry's legs, gently caressing the skin of his inner thighs.

"Did he tease you?" Snape murmured into his ear.

Harry nodded, blushing "Yeah."

He could have told Snape how much the Slytherin had teased him that evening on the Astronomy tower. That the things he had been doing were driving Harry crazy. That he had made him beg. But he didn't want to talk. He wanted to come.

The hands on his thighs were moving closer towards his groin and his heart hammered in his chest.

"Do you want to tease him too?" Snape whispered lowly.

Harry's eyes opened widely and he looked at the boy standing a couple of steps away. Malfoy was no longer grinning, but his eyes were dark with lust and anticipation.

"Yeah" Harry said, the idea causing his body to shudder.

Then he felt long fingers wrapping themselves around his cock. He let out a loud groan. He was aching for so long, so many times for the past couple of days that he was afraid he would come just by that.

"Easy, Potter" Snape murmured with a smirk "Tell Malfoy what to do" he added mischievously in a quiet voice.

Harry once again looked at Malfoy. The blond took two steps towards them, standing closer but not close enough for Harry to touch him if he reached out.

"Take off your shirt" Harry said in a quiet voice and Malfoy complied with a smirk on his face, taking his black button-up through his head "And your trousers and pants, too" he added quickly.

The blond chuckled, but reached to his belt and moments later stood naked, his clothes pooling at his feet.

Harry let his eyes wander up and down Malfoy's lean body. He was pale and so beautiful something twisted in Harry's insides.

For fuck's sake, how could he find Malfoy hot? He was the most annoying bloody brat in the world. And he was so bloody hot. How could Harry have not noticed through all those years?

His thoughts were interrupted by a moan that broke out from his own mouth when the hand on his cock started to move up and down in slow movements. He squirmed, pressing his back against Snape's chest, his eyes never leaving Malfoy's milky body.

"T-touch your chest" he said in a gasp "Your…your nipples" he mumbled quietly, his face burning from embarrassment.

Malfoy brought his hands up and started caressing his upper body, finally reaching his one palm to his right dark pink nipple. He brushed it with his thumb and his eyes flattered close at the sensation.

"Twist it" Harry whispered, trying really hard not to blink with his eyes.

Malfoy caught the hard nub between two fingers and rolled it, letting out a long groan.

He kept rubbing it, sending sparks of pleasure through his entire body.

"Wet your fingers" Harry breathed, not believing those words actually left his mouth.

At this command Snape purred approvingly into his ear and the sound went straight to his cock. He bucked his hips lightly but remained focused on watching Malfoy, who brought one of his hands up to his mouth. He parted his lips and licked two of his fingers, then took them into his mouth and sucked on them to get them wet, just like Harry wanted.

"Touch it" another whisper from Potter made Malfoy release his fingers from his mouth and move them to the left side of his chest. Very slowly he brought one wet finger to his nipple and circled it with the cold, moisturized fingertip.

Instantly he shivered at the feeling.

"Fuck" he moaned and threw his head back, not stopping teasing his nipple.

Right then he heard a lingering moan and opened his eyes abruptly. He saw Potter squirming in Snape's lap, the professor's hand pumping his cock in steady pace. Even though Potter seemed as if he was going to faint, he stubbornly kept his eyes fixed on Malfoy's hands and face. He was moaning not from Snape's pulls, but from watching him. Oh bloody hell.

"Fuck, Potter" he gasped, unable to look away from the mess the boy in Snape's lap was becoming. Becoming because of him.

"Tou…ahh-…touch yo-…y-your cock" Harry managed between his own pants.

Malfoy didn't need to be told twice. He reached with one of his hands to his crotch and wrapped his long fingers around his shaft. He let out a small hiss.

"Y-you can move" Harry breathed out and watched as Malfoy started pumping his dick "Slower" he added quickly, wanting him to match his movements with Snape's strokes.

Malfoy groaned in impatience but did as he was told and slowed his pumps. Merlin, it felt so good. And watching Potter, knowing he's feeling same things with their professor's hand on his cock was even more arousing. They were staring at each other for a long moment, each of them letting out small noises of appreciation.

"P-play w-…-oh, gods- play with your balls" Harry managed, his face flushing red as the order left his mouth. He earned a low chuckle from Snape and saw Malfoy reach his free hand lower to grab his sack. The blond immediately flushed and let out a lingering groan that echoed in the room. His voice was soon joined by Harry's moan, when Snape did the same thing to him, teasing his bollocks with his slender fingers.

"Oh fuck, professor" he bucked his hips in order to get some more of needed friction "Profe-ahh"

"There you go, Potter" the man murmured behind his ear "There's four days' worth of teenager's cum in here, is that right?

Harry nodded frantically, blushing at his teacher's language "Y-yes, sir…"

"Do you want to let it out?" he hummed, his hot breath tickling Harry's skin.

"Yes" he cried out "I've been waiting so long, please…"

Snape smirked under his nose and suddenly the movements on Harry's cock sped up.

"Oh gods, yes" he whined and looked at the naked boy standing several steps from him, jerking himself still slowly "Move faster, Malfoy, please, faster" he panted.

The way Harry said that sent a shiver down Malfoy's spine and he didn't wait a second to start jerking himself off properly. He swore under his breath, finally feeling that he was getting enough stimulation.

He watched Potter, bucking his hips frantically in time with his own movements. Their eyes met and both of them moaned loudly.

"Come on, Potter" Malfoy rasped "Come for me."

Harry let out a loud whine "Ah-…ahh, Malfoy."

Just as Malfoy sped the pulls of his cock, Snape did the same to Harry and with two more pumps they were both coming, Malfoy grunting through clenched teeth and Harry, unable to keep quiet, with his mouth forming a big "o" and groaning.

When Harry came down from his high, panting heavily, he noticed he was the last one to recover. Malfoy was also panting but he somehow still had enough strength to stand on his feet. Harry couldn't imagine doing that right now, instead he stayed sprawled in Snape's lap, the professor playing with his fingers with cum Harry had just shot.

"So thick" he purred "You really didn't come in four days, huh?"

Harry shook his head, still too out of breath to say something.

Snape patted his thigh approvingly. His other hand he brought to Harry's belly and dipped his fingers in cum that pooled there. He then raised it to Harry's lips.

"Taste yourself" the man said in a low voice.

Harry gulped and observed the cum coated fingers for a moment until he finally parted his lips and took them to his mouth. He hesitantly licked the long digits and sucked on them, instantly tasting a mixture of sour and sweet on his tongue and he groaned loudly, closing his eyes.

"Good boy" Snape murmured into his ear.

He let Harry lick the fingers clean and then took his hand back.

"Your detention is over, Potter. You may go back to your dormitory."

Harry opened his eyes and saw that Malfoy was already clean, probably casting the cleaning spell seconds ago, and was now throwing his shirt over his head.

He pushed himself off Snape's lap and reached for his clothes and wand in order to use the same spell Malfoy had.

"Uh-uh" Snape stopped him and Harry looked at him questioningly "You are not going to clean that with magic. You are to dress and go back to your room, still covered in your cum, Potter. Are we clear?"

"But, sir-…"

"Are we clear, Potter?"

Harry closed his mouth. The cum was already drying. If he didn't clean it now it would stick to him so much it would have to spend hours trying to get rid of it in the shower.

Even though, he nodded obediently.

"Good."

Harry dressed quickly, hoping he would get to the room and clean it off before it dries completely.

Once fully clothed, he looked at Snape, who gave him and Malfoy a nod "Go" he said.

Both boys left the office, closing doors behind themselves.

Harry turned towards the exit from the dungeons and started to walk to the tower.

"Potter" Malfoy called out.

Harry stopped and turned around to face him.

The Slytherin stepped closer and Harry looked at him questioningly.

"Want my help in cleaning?" he murmured, giving Harry a wicked smile.

Harry furrowed his eyebrows in confusion, but when he realized what the other was talking about, he blushed furiously.

"Um, I-I…"

"Whatever" Malfoy said and grabbed Harry by his wrist, pulling him along across the corridor.

"Wait, Malfoy!" Harry yelled, but the blond didn't stop. Instead, he dragged him through another corridor and into an empty classroom.

Once the door was closed, Harry yanked his hand from Malfoy's grip.

"What the hell, Malfoy?" he hissed, the blush on his face completely giving him away.

Malfoy didn't answer, instead he scanned the room and turned back to Harry.

"On the desk" he ordered.

Harry swallowed hard "W-what?" his all boldness from five seconds ago gone.

"On. The. Desk." Malfoy repeated "Now."

Harry gulped and stared at him for a moment, but eventually decided it'd be better to follow the order. He slowly walked to the desk and sat on it, his legs bent over the edge, hanging loosely in the air.

Malfoy approached him in less than a second and put his hand on Harry's shoulder, gently pushing him back "Lie down" he instructed.

Harry complied, leaning back until his spine was lying flat against the wooden table.

"There" Malfoy praised.

The blond parted Harry's legs and slipped in between them, making Harry's breathing hitch. He reached for the hem of Harry's t-shirt and slowly pulled it up. When the Gryffindor realized what was happening, he lifted his arms to make the process easier.

Malfoy grunted in approval and flashed him a satisfied smirk. He pulled the shirt over Harry's head and off his arms, leaving his upper body uncovered. Harry shivered.

"Oh, don't worry, Potter. You're gonna be hot in seconds" he said with the same smirk.

Harry looked down at his body and saw that cum that pooled on his belly hadn't dried completely yet. Just then Malfoy leaned down, hovering over his body and caught his eye.

Without breaking the eye contact, Malfoy stuck out his tongue and very slowly run the tip of it over the drying come.

Harry gasped.

"Oh my god" got out from his mouth.

Malfoy smirked at his reaction and hid his tongue back in his mouth, savoring the taste.

"It really is thick" he murmured more to himself, but making sure Harry could here every word.

Hearing the comment, Harry moaned loudly. It was so hot, having Malfoy lick his cum from his belly, and yet he must have added his share of dirty talk. Merlin, he's so screwed.

Malfoy dove again and slid his tongue across the skin covered with Harry's cum, gathering it, tasting, and swallowing. Harry was watching carefully, not believing it was happening. He felt his trousers tighten again and had no choice but to admit that he was getting hard by the fact that Draco Malfoy was licking his cum off him. Bloody hell.

Mafoy continued licking him clean and once he finished he smirked wickedly and, looking into Harry's blown pupils, dipped his tongue in Harry's belly button.

"Ahh!" Harry cried out when a spark of electricity went straight to his groin.

Malfoy withdrew his tongue a little just to dip it back a second later, this time devouring the inside of belly button with the tip, sending waves of pleasure through Harry's body.

Harry kept groaning and writhing under him, until eventually Malfoy pulled back and straightened up, licking his lips absently. Harry watched him through half-lidded eyes, trying to calm his breath. Bloody belly button, he thought.

"Sit up" Malfoy said with a mischievous spark in his grey pupils.

Harry did as he was told and pushed himself off the flat surface, sitting just like at the beginning, his legs still hanging freely.

He looked at Malfoy hesitantly. The blond then put his hands on each of Harry's thighs, smirking down at him.

"I made you hard, Potter" he purred, very pleased with himself.

Harry blushed furiously, his face becoming deep red, and yet he couldn't bring himself to look away.

"Yeah" he admitted in an embarrassed whisper.

Suddenly he felt Malfoy's hand on his groin and he whined.

"Want to come?" the boy asked teasingly.

Harry nodded frantically, ignoring the voice in his head telling him to have some dignity. His prick was aching and all he could think of was Malfoy's hand.

The Slytherin grinned and in one swift movement opened Harry's fly. He pushed his hand inside of his trousers and grabbed his prick. Harry let out a sigh of relief when the long fingers wrapped themselves around him.

When Malfoy's hand started moving up and down, he let out a lingering moan. Oh, so bloody good.

He watched for several moment as the blond's hand moved inside his pants, but eventually he was so overwhelmed that he couldn't keep his eyes open. He let them flutter close, panting into Malfoy's chest, which he was facing.

"That's it, Potter" the boy murmured "Come for me. Let out some more of this thick cum. Come."

And that's all it took for Harry. Malfoy pumping his cock hard and fast and talking to him in his low voice brought him to the edge and he came crying out "yeses" and moaning loud into the empty classroom.

It took him some time to recover. He was still sitting, resting his forehead against Malfoy's chest, panting heavily.

Malfoy slipped his hand out of Harry's trousers and brought it to his lips, licking at his fingers. When Harry noticed, he groaned loudly but stared at the quick work Malfoy made of cleaning his hand.

He started to feel slightly uncomfortable with the mess in his pants, so he reached with his right hand for the wand, but before he could get it he felt long fingers grabbing his wrist. Confused, he looked at Malfoy who was smirking.

"Don't" he said.

Harry furrowed his brows "What do you mean?"

"I mean I want you to go to your room with your cum still in your pants" he purred "So that with every single step you're gonna feel it. So that every single step will remind you that you have just come in your pants for me."

Harry closed his eyes and moaned at Malfoy's explanation. His cock was completely spent from two orgasms in a span of an hour and yet it gave a twitch of interest at the Slytherin's low voice.

He felt a pair of hands working on his fly and looked down to see Malfoy's pale fingers zipping his trousers. Once done, Malfoy didn't remove his hand; instead, he palmed Harry through the fabric of his jeans, making the boy bite on his lip hard and make a small, vulnerable sound in the back of his throat. Malfoy flashed him a smirk and pulled back, looking very smug.

"Back to your tower, Potter" he said, amused with Harry's little pants "Before I take some points for sneaking around the castle after curfew."

Harry gulped but nodded. He jumped off the desk and grabbed his shirt, quickly putting it on over his head. His hair must have been a real mess anyway.

He looked hesitantly at Malfoy, but the boy just lifted his eyebrow and eventually Harry turned to the door and left the classroom.

Malfoy was right. With every step through the corridors he felt how sticky it was in his pants. An enormous blush crept up his face and ears. He was so screwed.
