Bloody hell, Harry thought. After he sneaked out of Snape's classroom, he was supposed to join Ron and Hermione in the Great Hall, but there was no way he could go there with a pretty obvious bulge in his pants and his face beet red from thinking of what had just happened.

He made his way to Gryffindor tower, praying gods to be able to sneak through the corridors unnoticed.

Somehow he managed to get to the dormitory without bumping into anyone. Once in the safety of his room, he closed the curtains around his four-poster bed and tried with his all might to will the erection away.

Come on, he thought, focus. Think about something disgusting. Like Voldemort. Or Death Eaters. Yeah, that's a good one. No one would want to shag them. Well, except for Snape, but he wasn't really one of them after all. Snape, yeah. His pinning black eyes, boring into yours as if he could see straight into your soul. And his fingers. Those long, pale fingers…

His cock twitched and he let out a soft groan of need and desperation, throwing his head onto a pillow and taking a deep breath. You idiot, stop thinking about him.

And he tried, he really did, but every single time images of him sucking Snape's cock flashed right in front of his eyes.

"Think about something nasty, something revolting" he murmured to himself.

Hoping it would help, he closed his eyes. Come on, something so sickening it'll make you nauseous. The Dursleys. There you go. Think about Dudley and his stupid face. That's it, go away, hard-on, see you some other time.

To speed things up, he decided to get out of bed and take a cold shower.

The next day Harry's face was burning red while he was trying to come up with an excuse and answer his friends' questions about what he was doing for so long in Snape's classroom and why he didn't show up at dinner.

His thoughts wandered back to Snape. He had said Harry can't cum till Thursday. It meant four days. Does that mean that after this time he can finally masturbate in peace or that after four days he's supposed to come to Snape? How is he supposed to know? Would Snape want him to come back? What would he do if Harry did? Oh gods, would he wank him? Harry almost moaned at the thought, but quickly regained his composure. He had four more days to find out but he was sure it would be worth the waiting.

The images of Snape making him come accompanied him throughout all of his classes.

Later that day Harry was walking down one of the corridors coming back to Gryffindor tower when he spotted a familiar figure. Malfoy was leaning against the wall with his arms crossed on his chest. He wore a very satisfied smirk on his face.

"Well, well, Potter" he hummed and Harry shivered. He immediately remembered the burn of his bum and Malfoy's dick fucking his mouth, and felt his cheeks go hot and his trousers tighten at the memory "Wandering around the castle alone?" the blond asked in his velvety voice.

This voice went straight to Harry's cock.

"Fuck" the quiet mutter slipped from his mouth.

"Not exactly what I had in mind" Malfoy replied, giving him a dirty look, then grabbed Harry by the wrist. The blond pulled at his arm and dragged him up the stairs and out on the balcony on the Astronomy tower.

"What do you want, Malfoy?" he asked, gathering some pride and courage to look him in the eyes.

The Slytherin seemed rather amused "Oh, getting cocky, aren't we?" he asked, raising his eyebrow. He came closer to Harry, standing right in front of him "Don't you remember what happens when you're naughty, Potter?" he whispered, his voice low and dangerous, but at the same time seductive.

Harry swallowed hard and bit his lip to prevent any sounds escaping his mouth at the thought of the night two days ago.

His breath caught in his chest when Malfoy leaned in towards him "Are you still sore, Potter?" he asked darkly "Does it hurt when you sit?"

Harry's heart started to pound so loud he was sure the other could hear it – Y-yeah. I-It does – he whispered, looking away. Those last two days he was struggling whenever he was to sit hour after hour in his classes. He hoped the pain would be gone quickly, because McGonagall had already warned him after he had been squirming in his seat for the entire lesson.

"Good" the low whisper sent a shiver down his spine "Now turn around" he ordered with a cheeky face "I want to see if those arse cheeks are as red as I want them."

"W-what?!" Harry yelled, shocked. There were in the freaking Astronomy tower!

"I said turn around" Malfoy repeated, a note of impatience in his voice.

After three very intense beats of his heart, Harry eventually did as he was told and slowly turned around, facing the railing of the balcony and the grounds of Hogwarts.

"Bent over" the voice behind him said.

Harry gulped but obliged and bent over. He put his hands on a railing in front of him for support.

The very next moment he saw two pale hands sneaking around his waist and reaching the front of his trousers. Slender fingers opened the button and the fly, and then moved towards the hem of the jeans. Without hesitation Malfoy pulled the trousers down his thin, shaking with nervousness legs and then came back to grab the waistband of his pants, and finally slid them down to his knees, leaving Harry bent over with his naked bum in the air.

Harry closed eyes as feeling of embarrassment washed over him. He drew in a sharp breath when he felt cold fingers touching his arse.

"Still pink" Malfoy announced, grazing his fingertips across the cheeks. Harry groaned loudly "And still sensitive, huh?" he chuckled darkly and pulled back "I want them fucking Gryffindor red though" he said, and before Harry could process his words, Malfoy's hand came down on Harry's bum with a hard smack.

"Ahh!" Harry screamed as sharp pain emitted from his behind.

"Better hold onto that railing, Potter" he warned in a cheerful tone and then leaned to Harry's ear "I'm gonna spank you so. Fucking. Good." With that he brought his palm down again.

Harry gasped and tightened his grip on the railing, catching his lower lip between teeth and biting hard on it to stop himself from letting out any sounds. He didn't succeed though, not when Malfoy set a punishing pace and the smacks landed on his butt one after another.

"S-stop" Harry pleaded "Not here… You c-can't here" he managed through clenched in pain teeth.

"Oh, so you're worrying about being seen?" Malfoy chuckled "Well, if someone saw you like that…Quite a sight. I mean, the Boy Who Lived, bent over with his pants down for Draco Malfoy, being punished like a five-year-old brat…" his voice became husky "I wouldn't think much about being outside but about your throbbing ass and my hand."

With that Malfoy renewed the series of spanks, each of them landing hard on the tender skin with a loud smack. In no time Harry felt his eyes prickling with tears, his bottom stinging from the rough treatment.

"P-please stop it" he choked out, his voice cracking.

"Not quite done here yet, Potter" Malfoy replied in a cheeky tone and gave a particularly hard smack.

"OWW!" Harry cried out, letting his head slump loosely between his outstretched arms.

"Yes, Potter, let the whole castle hear your little screams" Malfoy said, sending more slaps to Harry's abused and now dark red backside.

Harry started sobbing, unable to stop the tears from falling, his ragged breath delivering not enough air to his lungs. And the smacks kept coming, now that the Slytherin brought his free arm to hold him in place and prevent from wriggling and squirming away.

"I hope it matches your frigging Gryffindor tie now" Malfoy said and gave Harry one more, extraordinarily hard smack. Harry cried out loudly.

And then it was over. No more blows came down sharply on his bottom, but cold hands appeared on the hot skin and started caressing it.

Harry drew in a sharp breath, which didn't escape Malfoy's attention.

"Sensitive, are we, Potter?" he mocked and squeezed the right cheek, which made the other boy moan.

Malfoy started massaging Harry's butt, giving each of his buttocks a good fondling, and Harry kept letting out small whines of pain and appreciation, still sobbing quietly at the burn from the spanking.

"Straighten up" the command came and Harry obliged without any protests. He let go of the cold railing, stood upright and turned around.

His face was stained with tears. Some new ones were streaking his cheeks, when he let out a quiet sob.

"Harry Fucking Potter crying for me" Malfoy breathed, his intense gaze piercing into Harry.

Not leaving his eyes off the wet face, he slowly moved his hands down Harry's back until they stopped on his well-spanked backside.

Harry whimpered and then let out a long moan when Malfoy's palms started to stroke his aching bum. The touches were almost gentle, so completely different from the strikes during the spanking. He groaned again.

"There you go" Malfoy murmured, not stopping caressing the sensitive skin "I bet you won't be able to sit tomorrow on that pretty arse."

Harry's face grew hotter and he closed his eyes, but he reopened them when Malfoy took his hands back and tugged at Harry's wrist instead.

The blond dragged him towards the wall and sat on the cold floor of the tower, pulling Harry down. Harry landed in his lap, sitting back to chest so that he was facing the grounds of Hogwarts.

He hissed when his naked butt brushed the fabric of Malfoy's trousers. His own, along with his underpants, were still pulled down to his knees and suddenly he felt too exposed and vulnerable and embarrassed.

Before he could do something, Malfoy's hands came to his front and drew his attention. One of them rested on his thigh while the other slipped under Harry's shirt and started stroking his stomach, chest, eventually coming to one of the nipples.

Harry groaned loudly when Malfoy brushed his thumb over the hardening nub and then started to rub it and roll it between two fingers.

"So responsive" Malfoy purred in his ear, still teasing his nipples. He then added the movements with his other hand, massaging Harry's thigh, the bare skin very sensitive in this particular area, so close to is erection.

He didn't have to wait long, as Malfoy suddenly moved both of his hands lower, to Harry's aching cock.

Harry felt long fingers wrap themselves around his dick and he threw his head back, moaning.

"Good boy" Malfoy murmured with a smirk on his face.

The Slytherin started to move his hand up and down, slowly jerking Harry off. It was so bloody good. Two days of constant thinking about wanking and cumming and there he was, finally. Then he remembered it was just two days. That meant two more to go. But he wanted to come. He needed it, so badly. He just couldn't bear it anymore.

Then he remembered Snape's warning tone and wondered what would the consequences be if he disobeyed. He swallowed hard; probably nothing good. He had to stop this before Malfoy's skillful hands would make him cum.

"M-Malfoy" he gasped, trying to get the other's attention "Malfoy, I c-can't c-…ahh…" he moaned when Malfoy twisted his wrist just under the head of his cock.

"I know you can't come, Potter" the blond replied "Just had a little talk with Snape" he smirked under his nose, making Harry whimper when he brushed his thumb over the tip "You're not allowed to cum, but I can still play with you a bit" he purred.

"N-noo…" Harry groaned, knowing he was in deep shit. Malfoy would not stop even if he asked him to; or more like especially because he had asked him to stop. Bloody hell.

"Shh" the blond hushed him in a whisper, his hot breath tickling Harry's ear and making the boy squirm in his lap.

Harry looked down and for a long moment watched as slender fingers moved up and down his shaft. His face flushed as he thought that these were Malfoy's hands. Malfoy was jerking him off. Fuck. This little bastard that he had been hating for all those years was now touching his cock, playing with it and bringing Harry to the edge. It was so surreal, yet so hot that Harry couldn't take his eyes off the gracious hands of the Slytherin pleasuring him.

Malfoy set a slow pace. He was stroking Harry lazily, torturing him with each slow movement, teasing him but never giving enough attention to bring him release. At some point Harry threw his head back, resting it on the blond's shoulder, giving in completely to the pleasure Malfoy was giving him.

He was panting, occasionally letting out small whines every time Malfoy stopped to play with his sensitive head. The blond's lazy strokes were driving him crazy, so he tried to jerk his hips upwards and get some more friction but was immediately stopped by Malfoy's free hand that grabbed his hips. Harry groaned in protest.

"So helpless" Malfoy chuckled "You want to fuck my hand, Potter?" he murmured into Harry's ear, grazing his lips across its delicate skin.

In response Harry moaned loudly "Fuck yes, please" he panted "C-…can I?"

Malfoy let go of his hip and brought his hand back to Harry's chest "Let's see."

With that he stopped moving his other hand but still had it wrapped loosely around Harry's cock.

Harry raised his head a bit from Malfoy's shoulder and looked down through half-lidded eyes. He tentatively moved his hips up, his dick sliding into the warmth of Malfoy's fist. He brought his hips down and then pushed up again, gradually speeding up his movements.

Malfoy tightened his grip a little, which made Harry moan, throwing his head back on the blond's shoulder. He started to pump into the hot tunnel at a steady, rapid pace, taking from it as much pleasure as he could.

"That's it, Potter" Malfoy said in a deep, low voice, using his other hand to rub Harry's nipples "Fuck my hand."

Harry groaned. He felt his whole body getting unbearably hot, his face on fire from arousal and embarrassment "Fuck" he grunted, squeezing his eyes shut.

Malfoy let him fuck his hand for a couple of moments until he suddenly loosened his grip and took the hand away, making the Gryffindor whine at the loss. His other hand that was caressing Harry's chest he threw across Harry's waist to keep him in place.

"You had your fun, Potter" he smirked "Now hold still" he said and wrapped his long fingers around Harry's shaft again.

Harry bit his lower lip with his teeth when Malfoy started to pump his cock, going back to lazy, torturous strokes. Harry groaned desperately but had no choice but to give up to them.

He focused on how amazing Malfoy's hand felt on his dick. He had never had anyone jerk him off before – well, except for Snape two days ago – but now he couldn't imagine wanking off with his own hand. Suddenly masturbation seemed pathetic and he doubted it would ever be enough to satisfy him after what he was experiencing now.

Malfoy kept moving his one hand up and down and brought the other to play with Harry's balls. Immediately the boy moaned and writhed in the Slytherin's lap.

The blond chuckled lowly "Feels good, huh?" he teased.

"Yeah, so good…" Harry moaned "Feels so good."

Malfoy smirked to himself. He continued playing with Harry's balls, fondling them and squeezing slightly, still pumping his rock hard cock. Then he sped up his movements and began stroking Harry fast and hard.

"Oh gods" Harry half moaned, half panted. So fucking good.

He felt lips on his ear.

"Remember you can't come, Potter" an amused voice warned him, hot breath ghosting over his skin and sending shivers down his spine.

"Ohplease Malfoy" he begged in a high-pitched voice "I…ahhh…I-I need…" he wasn't even able to finish the sentence he was so overwhelmed and lost in ecstasy. How on Merlin's beard could he not have done that before?

"Uh-uh" the Slytherin replied teasingly "Not tonight, Potter."

"M-Malfoy ahh!" he moaned so loud he was convinced half of the castle could hear him "Imbeggingyouplease!"

The blond chuckled "So needy" he whispered into Harry's ear "You can beg as much as you want, you will not come tonight."

Harry responded with a helpless whine.

He kept moaning, until he felt familiar heat pooling in his lower belly. His whole body tensed, ready to give him his orgasm, and right then Malfoy stopped his movements, taking his hands away and leaving Harry right on the edge; breathless, aching and unsatisfied.

"No…" he groaned heatedly.

"Shhh" Malfoy whispered, putting his hand on Harry's thigh and stroking it gently.

Harry was panting heavily, his chest rising and falling rapidly, with his head still on the blond's shoulder.

"Good boy" he murmured into his ear "Catch your breath and we're out of here."

Harry looked at him questioningly; he definitely needed some time to will the erection away, if it was even possible, and by the feel of something pressed against his lower back he suspected Malfoy was pretty hard too "Why?" he panted.

"Because you were moaning so loud that we were heard at least by the prefects" he said darkly with a self-satisfied smirk "Now let's get going before they send here McGonagall or this pathetic excuse for a headmaster."

Harry's brows furrowed, but he didn't manage to say anything, because Malfoy's hand suddenly appeared back on his sack, fondling his tightened balls, and he moaned.

"Yeah, so bloody needy" Malfoy purred. After a moment he took his hand back and slid from behind Harry, standing up and helping him to do the same.

Once on is feet, Harry realized the state he was in. He was half naked, with his trousers and pants pushed down to his knees, his aching cock still hard, standing proudly against his belly, his red arse burning from the spanking, out on display, and his flushed face, eyeing carefully the boy in front of him.

Malfoy was looking him up and down, and suddenly Harry felt even more ashamed that he had felt earlier and immediately reached down to pull his clothes back on and cover himself. When he was zipping his jeans, Malfoy stepped closer to him, reached his hands around Harry and slid them inside the trousers and underwear.

A small whine escaped Harry's mouth when the Slytherin stroke his buttocks and then squeezed each of them, the attention given to the irritated skin sending wave of pain through Harry's body.

Malfoy then slid his hands out of the jeans and pulled back, turning towards the exit.

"Good luck with sitting tomorrow, Potter" he said, amused, and left the tower.

Harry stood there for a few minutes, staring after Malfoy's back, until he finally wake from the trans and headed towards his dormitory, asking gods for not being caught.
