A Rainbow of Potions
“Come in, Potter,”
Harry came into Snape’s office for his seemingly daily detention and closed the door behind him. His cheeks and nose were pink from the cold winds in the hall and Harry was silently thanking the fire burning brightly in the fireplace before settling on the desk Snape had prepared for him.
“You will be brewing the 7 colored Incutientia potion tonight. All ingredients are in the closet; instructions are on the board. You may begin,” Snape said, waving a hand towards the closet at the other end of the room in a dismissive manner. Harry squinted his eyes, reading the instructions and - realizing how complex the potion was going to be - went to collect the ingredients with an irritated huff.
He had been missing a lot of Quidditch practices because of the detentions, and his homework pile seemed to be growing taller everyday. It seemed like today’s detention was going to take a long time too. He brought all the ingredients back to the desk and began working, fuming internally.
Snape watched the boy work with great annoyance. Harry was more defiant and arrogant lately and while he had had great pleasure in taking points off Gryffindor and watching him trying to control his anger, it was starting to get on his nerves as well. He just knew Harry would somehow ruin his potion and he wasn’t particularly looking forward to whatever ridiculous concoction he would be making tonight.
So far, so good. Harry carefully added the flower essence, turning the clear potion into a soft purple hue - just as instructed - and let it simmer for a little before separating them into 7 vials and adding the required ingredients, turning them into glittering colors of the rainbow.
“Sir, I’m done,” Harry called. Snape stopped his grading and glided towards the boy, his robes sweeping behind him. Snape held up the vial containing the red potion, inspecting it. It looked alright, but knowing Harry, who knows how it will work? Snape held the vial in front of Harry, who was taken aback.
“Drink it,” Snape commanded.
“Excuse me?”
“I said drink it,”
“But-”
“Incutientia is just an energizing potion, Potter, it won’t kill you. Now drink it,”
Harry finally accepted the vial reluctantly, eyeing his professor in distrust before drinking it all in one gulp. It tasted a little bitter but not unpleasant.
“Now,” Snape waved his hand and the instructions on the board disappeared. “Write down the steps of making this potion and what you’re feeling after taking the first one.”
The next 10 minutes were spent in silence with only the sound of a quill scratching parchment echoing in the room. Harry noted that except for feeling slightly warmer, there were no other effects. And certainly no ‘energizing’ effect. Was his potion a failure?
Snape leaned against his desk and started rifling through the essays, but found it to be extremely difficult. There was a smell in the room he hadn't noticed before, and it was driving him insane. It smelt like treacle tart, something woody, and a faint hint of soap. It was intoxicating, and the more he inhaled the scent - which was almost suffocating in the closed space - the more aroused he became. He looked over at Harry to see if he was feeling the same and immediately realized that the scent was coming from Harry. Snape gripped his desk tightly, trying to steady himself.
“Sir, I’m… done…” Harry trailed off as he looked up to see Snape hunched over his desk, his face flushed and his breathing ragged.
“...Sir?” Harry asked slowly. What the hell happened to Snape?!
“Potter, what… did you do… to the potion?!” Snape snarled, panting.
“I followed the instructions! I ma- are you okay?” Harry quickly caught Snape’s shaking arm, alarmed by the sight of the man in front of him who looked seriously ill. The sweet, intoxicating scent grew stronger the closer Harry was to him, and he bit back a moan that was threatening to spill from his lips.
“I’m fine,” Snape said through gritted teeth, trying to move away from Harry. “Just… just drink the orange one.”
Harry was hesitant to move away from the man who looked like he could fall at any time, but he also didn't want to earn more detentions, so he quietly drank the orange potion - which tasted like nothing in particular, but was a little hot in his throat - before going back to Snape.
Harry's touch felt incredibly warm even through the layers of fabric. Too warm. Snape unconsciously let out a soft gasp at the sensation. Harry mistook it as a gasp of pain and began rubbing Snape's back as an attempt to soothe him, which didn't help his arousal at all.
"Potter," Snape muttered, his voice husky and low.
Harry's green eyes met with Snape's obsidian ones and his cock twitched when he saw the obvious lust pooling in those eyes and dripping from that voice. Harry tore his gaze away from Snape's bewitching stare and looked down, his eyes widening at the sight of the very painful-looking tent in Snape's trousers. Harry swallowed.
Without thinking, Harry ran his hand over the bulge, eliciting a hiss from the older man, which went straight to Harry's cock.
Snape shivered as Harry touched him and, feeling very warm now, started to unbutton his robes. Harry, who was feeling just as hot and bothered, started to undress himself too; the view of his Quidditch toned body giving Snape a shiver up his spine.
When they were both topless and panting with desire, Snape immediately snaked his arm around Harry's slim waist and pulled him close, groaning as his skin came in contact with Harry's. The younger wizard threaded his hand through Snape's hair and crashed their lips together. They wasted no time in deepening the kiss, tongues tasting and exploring each other's mouths. Harry moaned softly. Snape tasted like wine and dark chocolate. He didn't know Snape tasted so wonderful. He bit Snape's lower lip, causing the older man to shiver in delight.
His hands slowly slid down Snape's chest as he broke the kiss and started licking and kissing along Snape's jaw and neck. Snape gasped when Harry found a particularly sensitive spot near his collarbone and Harry, delighted in his find, started sucking and biting softly at the skin. Harry's fingers traced Snape's toned chest and stopped at a nipple, fondling and twisting the nub.
Snape couldn't think at all. He was overwhelmed by the amount of pleasure Harry's incredibly warm hands and mouth were giving him. He couldn't even stop the gasps and moans continuously spilling from his kiss-swollen lips. Harry broke away from him for a moment, giving the older man time to remember his name, but was back in no time, kneeling in front of Snape with a smirk.
Harry had figured out that this whole thing was caused by his potion failure, and was excited to see what the yellow potion will do. He was surprised when he felt his tongue tingling and saw that it was getting longer, almost like a snake's.
Harry looked straight at Snape's lust filled eyes as he bit his zipper and slowly pulled it open with his teeth before freeing Snape's aching cock. Pleasantly surprised at the sight of the red, raging erection, Harry let his new tongue flick against the tip - making Snape moan - before coiling his long, slick tongue around Snape's shaft and swallowing his length.
Snape threw his head back, groaning as he felt Harry's hot mouth and skillful tongue around him. Harry started bobbing his head and, slowly but surely, deepthroating his cock. Pleasure shot through Snape and he started to buck into Harry's mouth, his hands tangled into the boy's messy hair. Harry's long tongue continued to slither and wrap around him as he continued to deepthroat Snape repeatedly, creating an immense vacuum-like sensation around Snape's cock.
Snape arched his back and felt his balls tighten. He was going to come!
Harry seemed to notice it too and immediately wrapped his fingers around the base of Snape's cock and squeezed, preventing him from coming.
"Harry!" Snape growled in frustration. Oh, he was so close, so close!
"Not yet," Harry chuckled and went to drink the green potion. As he swallowed the last drop, he became increasingly aware of his body, more specifically, his muscles.
Harry went back to Snape and pushed him onto his desk, the essays cleared away by a single swipe of his arm. He pulled Snape's trousers and pants off the older man who was too aroused to care.
Harry smirked as he bent over and started licking and sucking Snape's chest, giving extra attention and bites to the two hard nipples who seemed to be happy with the rough treatment. Harry licked his fingers and slowly inserted them into Snape's arse, careful as to not cause any pain. Snape gasped and arched into Harry when he felt himself being breached. The finger slowly began pumping in and out, and when Snape was hissing with need, Harry added another finger. And another. And another. Snape couldn't hold back the long, drawn out moan as he felt Harry's fingers scissoring him open.
Harry's tongue slowly trailed down across Snape's stomach, past the throbbing erection, and stopped at Snape's puckered opening as Harry lifted his legs.
Snape screamed when Harry gave a long, slow, and languid lick across his opening, the pleasure bursting through him like electricity. Harry didn't stop, in fact he seemed encouraged by it, and circled his skillful tongue along the edges twice before plunging it in his hole, easily finding Snape's prostate with his long tongue.
"Harry!" Snape gasped loudly as he felt Harry's tongue vibrating against his prostate, making fireworks explode behind his eyelids. Due to his extreme muscle control, Harry could angle his tongue and vibrate it to hit at exactly Snape's sweet spot, making the man writhe and shudder with intense desire.
Harry couldn't take it anymore. The noises Snape was making was driving him crazy, and he quickly downed the blue potion before stripping his trousers off and freeing his own aching cock. He stroked it a few times using his precum as a lubricant and settled himself between his professor's spread legs.
"Severus," Harry hissed, rubbing his tip against Snape.
"Harry," Snape replied with a moan, grinding against the boy's cock, delighted with the way his name rolled off the boy’s tongue.
Harry slowly pushed into Snape's arse and groaned at the tightness and heat that surrounded him. Snape screamed out his pleasure as Harry's cock slid in inch by inch.
Harry was extremely horny, but he didn't feel the need to come as intensely as before, so he settled his hands on Snape's hips and let his legs over his shoulder before he slowly pulled out and thrust in just as slowly.
Snape writhed beneath Harry, lost in ecstasy but also frustrated at the agonizingly slow pace of Harry's thrusts.
Growling, he pulled Harry down into a harsh, deep kiss before gasping out, "Harder!"
Harry obliged, speeding up his thrusts until he was slamming into Snape, who moaned and screamed whenever Harry hit his prostate.
Slowing down a bit, Harry reached over and gulped down the indigo potion before continuing to thrust in and out of Snape, who had started yelling nonsense out of pure pleasure.
Harry suddenly felt his precome leaking more rapidly, making Snape more slippery but still incredibly tight and warm. Snape felt it too for a short moment before electricity shot through him. He moaned as he felt himself getting hotter and more sensitive by the second.
Harry shifted a little, and in his new position was able to hit Snape's prostate with every thrust.
Snape's back arched, his toes curled, and he screamed as he released his mind-blowing orgasm, splashing his and Harry's chest. Harry immediately wrapped his hand around Snape's cock, pumping it.
Snape was overwhelmed by the dual sensations and was feeling incredibly sensitive. He couldn't stop coming as Harry continued to thrust against his prostate mercilessly, making moans and gasps and screams spill from Snape's lips. He couldn't think of anything else other than the waves and waves of pleasure that his continuous orgasm was giving him.
Harry had the mind to quickly grab the last violet potion and gulped it down before continuing to pound into Snape. He felt his balls tighten and leaned down to capture Snape's lips in a passionate kiss. With his hand still pumping Snape who was still coming, Harry came with a scream, "Severus!"
Snape too cried "Harry!" As he felt the hot liquid shooting into him. Feeling Harry pulsing in him, Snape shivered and gave one last spurt of come before collapsing onto the desk, thoroughly spent and exhausted. Harry also collapsed above him, panting.
They didn't move for a while, trying to relearn how to breathe after their exhilarating activity.
Snape recovered first, gently embracing Harry as he found his wand and casted a cleaning charm on them both. He held the boy close as he softly murmured a spell to transfigure the desk into a bed, and sighed happily as they sank down on the soft mattress.
From his gentle, steady breathing, Snape correctly guessed that Harry had fallen asleep in his arms. He conjured a blanket and covered them both in the smooth, warm fabric and gave Harry a small goodnight kiss as he realized the passionflower essence Harry had mistakenly added instead of the lavender he was supposed to add.
"A happy little accident," Snape thought to himself as he smiled and fell asleep beside Harry.
This was just a silly PWP I had in mind lol. This is my first time writing smut! What do you think? Here are the effects of each 'ruined' potion if you're curious:
Red: makes the drinker release pheromones that attracted anyone who inhales the scent within the vicinity. Takes some time to work.
Orange: raises the drinker's body temperature, making their touch especially warm for others
Yellow: makes the drinker's tongue snake-like
Green: gives the drinker extreme muscle control so they can control even the tiniest tendon.
Blue: gives the drinker more stamina and also makes it impossible for them to come.
Indigo: gives the drinker's body fluids strong aphrodisiacal properties that raises another person's sensitivity when absorbed through the mucus lining.
Violet: releasing all the tension in the drinker's body at once and also washes out the effects of the other potions.
Also, yes, I'm still gonna update Lilies, it's just taking some time hehe. Please review :D
