Hermione was humming while she brushed her hair. She was standing in front of the mirror, dolling herself up. It was all a plan she had put together. She wants Harry, all for herself. She had dropped many hints over the last months, trying to make her intentions clear only for him to be too oblivious to notice them or he was too shy to act on them. Either way she had enough. She had to up her game.

Her hair was tied back into a ponytail leaving her face free without any distractions. On her face was make-up, shadowing her eyes while on her lips was a gryffindor red lip gloss. On her neck was a blank collar, nothing expensive, sitting snugly around her throat. Her crop top was probably the most eye-catching. In bold letters, right across her chest stands "Snap my choker". It ended under her ribcage, leaving her toned stomach free.

"Snap my choker" was a bold move. She wasn't completely sure if he knew what this meant. But he was a horny, male teenager and a muggle-raised wizard. She guessed he would know. And if not, her outfit will finish the job and rile him up.

Finished was her look with a pair of shorts that left the bottom curve of her bum visible, hugging it tightly, showing it off how round and toned it got from carrying all the books up and down the stairs. To enhance the look, she was wearing a pair of heels to make the muscles in her calves and bum flex, making it even rounder than normal.

Putting the brush aside she admires herself in the mirror. She was proud of putting this outfit together. It was showing her body off in the most sinful way, a way that she would never consider wearing if she didn't put on a special notice-me-not charm on herself. Only Harry was able to notice her.

She turned around looking over her shoulder, shaking her bum towards the mirror. The bottom of her bum peeked from under her shorts, showing how defined it was.

"You look hot, Granger," she said to herself, dropping a spank down on her cheek, making it ripple slightly from the impact. Deciding she was good to go she started to descend the stairs from her dorm, leaving an audible click with every step she took. Her hips were sexily swaying to her stride. Some girls were on their way up, making Hermione's heart beat raise but she shouldn't have worried. They were completely ignoring her, not even sparing a glance at her. Her charm worked perfectly.

Harry was sitting on the couch in front of the fire, doing his homework. That was when he heard the clicking of high heels descending from the stairs towards the girl dorms. Turning his head around, his jaw dropped when he saw Hermione descending, wearing the most sinful clothes that were leaving most of her body exposed.

His eyes glued instantly to her high heeled feet, traveling up her long legs, noticing her shorts clad hips, swaying from her heels before going up further. He rested on her flat stomach until he catched in the corner of his eyes the bold letters across her chest.

'Snap my choker,' he read. 'She can't possibly mean…' His eyes snapped to her neck, finding the answer to his question. There was a choker sitting snugly around her neck. Finally landing on her face, he noticed her make-up, which she had only worn once, at least that he knows off but not in this way. She threw him a wink, grinning sultrily. She had already crossed half the room, heading straight for the portrait hole.

This gave him the chance to look at her backside. Her hair was tied into a ponytail while her toned back was nearly blank with only her crop top covering the top half. That left him only with her bum. It was clad three-quarters with the bottom curve visible. It swayed and bounced hypnotizingly while she walked towards the portrait hole. He couldn't make himself look away.

Only when she disappeared through the entrance, his brain began to work again. He closed his mouth and tried to make a reason for what just happened. His best friend and secret crush, not that he will tell her that because of reasons, walked through the common room in what he nearly would say the sluttiest outfit he never would have guessed to see her in. But it seems like his bookworm friend was quite kinky.

If she just wouldn't have that look of pure determination on her face like she is about to suck half the boys of Hogwarts, He couldn't let that happen and let her ruin her reputation. He jumped off his seat, leaving his homework behind, quickly running after her. When he slipped through the portrait hole, he instantly locked onto her bum before rounding the corner.

Determined to catch her, he ran after her. When he got around the corner, he silently walked up to her before lifting her around her waist and covering her mouth, muffling her squeak when he pulled her into an empty classroom. Setting her down on her feet again, he takes out his wand, locking and silencing the room. When he was done warding the room, he turned around to lock eyes with her.

"Merlin, what are you doing? Are you out of your mind?" Harry heatedly asked her.

"What is your problem now?" Hermione replied, crossing her arms under her breasts pushing them slightly up.

"You shouldn't be wearing… that in front of all the boys," he argued.

"I can wear whatever I want," she said defiantly.

"But what about your career, your studies, your grades?"

"Who said you can't have both?" she asked back, with a raised eyebrow.

"But the boys will take advantage of you and… and just think of the rumors," he replied.

"So what?" She asked. "Who are you to try to stop me?"

"I am your best friend and I want to save your reputation," Harry finally answered dejectedly, sensing she had set her mind on this.

"Thanks for your caring but I want to suck cock," Hermione said, mentally adding 'yours preferably'. "And I want to find the biggest cock, and push it down my throat to snap my choker and you are not going to stop me or tell me what I should do or I should not." Holding his hands up, he turns around and starts walking towards the door without a fight.

'Fuck, that wasn't clever, Granger,' she scolds herself mentally. She ran towards him, grabbed his hand and spun him around, pushing him into the wall beside the door. "You noble prat," she whispered, craning her head towards his face. She noticed how tall he had grown. Even with high heels and pressing her body into his, he was still more than half a head taller. "Of course I wouldn't walk around like this in front of other boys except one." She winks at him.

"M-me?" Harry stuttered.

"Yes, silly. Didn't you notice how nobody even cared how I walked through the common room or were your eyes just that much glued to my butt?" Hermione grinned mischievously. He blushed bright beed red. Trying to fight back the blush, he clears his throat.

"But why me?" he asked.

"You still didn't figured it out? Boys…" she rolled her eyes. "Because I want you and we were flirting for months now and you didn't make a move."

"We were flirting?" his eyes widened when he realised what she was saying.

"Yes."

"Uhh…" his brain stopped working again.

"Maybe you will get it when I do this," she stated before pulling his head down, closing the remaining inches between their lips. She smashes their lips together and starts kissing him passionately.

After a few seconds, he realised his best friend was kissing him, he started to kiss back, letting his hands wander down to her waist, gripping them before he went further down grabbing her butt she was teasing him with.

Harry moaned into the kiss when he felt his fingers sink into the softness of her arse, feeling her muscles flex from her heels. Hermione swallowed his moan before groaning right back at him when he started kneading her bum. After a few minutes of making out, she broke their lip lock.

"Just to clarify: I want to only suck your cock," she said in a serious voice. "When we started flirting, I started to train my throat for you. I started practicing with a five inch dildo and worked myself up to eight inches," she grinned impishly at him.

"I am so good at it now that I have no gag reflex and can hold it down my throat easily. Sometimes I even did my homework in the common room while I had it down my throat, no one the wiser. Nobody could see the end because I had it in my mouth too. That deep I could take it."

Harry groaned at the image, his pants getting tighter. He braced himself against the wall. Hermione smirks at him. She squats down, her bum nearly resting on her heels, she spreads her knees wide for his viewing pleasure. Her bum looked deliciously in her shorts from above.

"But don't worry," she looks up at him with a sinful smile on her face. "I would love to suck your cock even if it won't break my choker because it's not big enough." She giggled at that. Harry raised an eyebrow.

"Not big enough, huh?" he said. His face showed his amusement. "I wouldn't be so sure about that. Go look for yourself." She starts fumbling with his belt and zipper. Grabbing his pants and boxers at the same time.

"Well eight inches are a lot and the choker didn't break. So don't let your ego hit you if you aren't biiii-ig…" Hermione was silenced when she yanked his boxers and pants down. Not expecting it, she got hit squarely in the face by his cock. His cock stood erect, the head weeping with precum. Her eyes went cross trying to take it in. Harry smirked at her expression.

"Well not as little as you thought, huh?" he taunted, clearly enjoying her shocked expression. She mutely nodded, taking his cock in. The angry looking tip had gathered more and more precum. Her eyes wandered along his underside, hungrily eyeing every single inch. At the base her eyes catch his big balls, looking full of cum for her to suck out.

Taking her wand out from her invisible wrist holster, a gift from Harry, Hermione conjures a measuring tape. Starting at the base, she lets it start to roll out. Inch by inch it got longer and longer.

At five inches she got aware that it already surpassed her smallest dildo. At seven inches her eyes widened because there was still so much to go and his cock was bigger than her second biggest dildo.

At eight inches she gasps. Even her biggest dildo couldn't compare to his cock. The tape stopped at a little over nine inches. Her jaw dropped.

"That is one more inch than my biggest dildo," she said breathlessly. "This can't be possible. It looks so much bigger than that." She vanishes the tape before putting her wand into the holder again. She took a hold of his cock, gasping again. "You are so much thicker than my dildo. Look. I can barely wrap my hand around it." Hermione wrapped her second around it and started stroking it. "My hands look so tiny compared to your huge cock."

Harry groans in agreement. She licked her lips at his precum covered crown. Sitting up, she licks it off before leaving a lingering kiss on the head, puckering her lips on it and looking deeply into his eyes. Never breaking eye contact, she starts to trail kisses on the right side of his cock down to the base. Going lower she kissed each of his full balls before lapping at them.

"So good. So tasty. And so big," Hermione moans. She let go of his cock, letting it drop on her face. She took one of his big, smooth balls into her mouth, sucking on it while swirling her tongue around it. Switching to the other one, she gave it the same attention. She worshipped his brimming full balls.

His cock lies across her face, dividing into two. She tried to look around it into his eyes but his girth was so big, even in her peripheral vision she saw it. The head of his cock was resting on her hair, weeping precum on it but she didn't care. Pulling back she lets his ball pop free and engulfs his crown.

"Look at you. You look so pretty with my cock in your mouth," Harry groaned. She started to bob up and down. His head was bumping into the back of her mouth. Hermione braced herself before she slipped it into her throat. Instantly she regretted running her mouth like that. It was way more difficult than her small dildo. She choked around it and couldn't get more than a third in her throat. His girth was just too much.

"Huh, and I thought you were practicing," he taunted. "Such a big mouth and still can't fit it. You need a real man's cock instead of your puny dildos." She went to pull back to retort but he put a hand on her head. "Oh no no no. You aren't going anywhere. I am going to snap your choker, like you wanted me to."

Harry bent her head back, lining her throat up, making a straight path for his cock. Taking a half step forward, he slowly pushed his cock down her throat. Hermione's eyes widened and began to water. His cock was straining against her throat, making it bulge, and stretching her choker. When her lips were resting at his base, she grabbed his thighs, trying to steady herself for a rough pounding for her throat.

"Urgh. Your big brown doe eyes. They are just pleading me to fuck your throat," Harry groaned. Hermione couldn't focus on anything else than his huge cock reshaping her throat. She squatted in front of him with her bum resting on her heels and her throat lined up like she swallowed a sword but instead it was his big cock.

Her choker was pressing against his cock. Something her dildo didn't achieve. She wasn't prepared for his girth. Her dildo's girth was slightly above average but his cock was putting even that to shame. She guessed a few thrusts would be enough to snap her choker. But Harry wasn't moving. Thankfully she even trained to hold her breath. Drool began to pool in her mouth. Hermione swallowed around his cock.

"Good girl," he praised. Her eyes widened while a tingle ran down her spine making her shudder. She swallowed again around him. "Yes, just like that, my good girl." She knew right then that she had a praise kink. Harry pulled back giving her a chance to take a breath through her nose before he pushed down again. His balls landed on her chin. They felt quite heavy.

Her choker was straining against her neck but it didn't snap. He started to thrust, finding a rhythm. Everytime he bottomed out, it was announced with a slap of his balls against her chin. It wasn't exactly how Hermione imagined this but she couldn't be more turned on. Harry was using her for his own pleasure, reshaping her throat for his needs. Her thong was already drenched with her juices.

"Ahh you look so good with your lips wrapped around my cock," he moaned when was fully hilted and stopped his thrusting. "My balls rest perfectly on your chin. And the way you try to suck me back in everytime I pull out. Be a good girl and swallow around me again." She stared into his eyes and swallowed.

"Nice and tight. I can't wait to fuck your little pussy and reshape it like your throat. You are mine now." He imagined what he would do to her. If it was possible his cock got even harder and twitched in her throat. Her throat was wrapped around him like a glove. Harry's cock was testing the limits of her choker.

"Fucking hell. You are so tight," he growled. Her lips sealed around his base suckling it while a lone tear fell from her eye. He glanced past her face down to her swell of her bum resting on her heels. Harry remembers how they were bouncing with every step when Hermione walked past him. He imagines how he would make them jiggle when he takes her from behind. He growled and his cock throbbed hard in her throat.

A loud ripping sound could be heard and Hermione's eyes widened when her choker fell away from her neck.

"There, my little minx," he smirked. "Just like you wanted. Your puny little dildos are nothing to my cock." She meekly swallowed around him in affirmation. Her pussy was clenching around nothing, leaving a wet spot on her shorts. He started to thrust again, resuming his pace, and pushed himself to the edge.

"Hnng… I want you to swallow every single drop, understood?" Harry grunted. Hermione answered with another swallow around his cock. "Good girl." He thrusts two more times. "Here it comes."

She felt his balls twitch on her chin before his cock seemed to expand a little and his cum traveled through his cock before it shot directly into her throat. She helped by swallowing, making it land in her empty tummy, quickly filling it up with his creamy treat. She moaned. Their eye contact never broke.

Harry pulled his cock out of her throat, coating her throat on his way up. When only the head was in her mouth, his cum hit her flavour buds, his taste exploded across her tongue. Her eyes went cross and she greedily swallowed the remains down. When the flow ebbed, she focused again and puckered her lips on his crown before squeezing the last of his cum out with her hands, making a show of swallowing. Hermione left a lingering kiss and stood up again.

"You taste so good," she purred, slightly stroking his cock again. But Harry's focus was on her wet spot in front of her shorts.

"You like sucking my cock that much?" he asked.

"Yesss, it turns me on so much," she purred again. Harry sneaked a hand down, behind her shorts and thong. He slipped his middle and ring finger inside her and drew circles on her engorged nub.

"Are you close?" he growls into her ear while nibbling on it.

"Yeah…" Hermione breathed. "Oh Merlin, I think, I am… Ungh…" She couldn't even finish before she came. She turned his head and kissed him heatedly. Stars exploded in front of her eyes. She rode his fingers, trying to prolong her orgasm as long as possible.

They broke the kiss when Hermione came down from her high. Harry slipped his fingers out of her pussy, inspecting them. They were covered with her juices. He put them into his mouth, sucking them clean. She mewled at his display and pulled him into another kiss, shoving her tongue into his throat, tasting herself.

Taking the initiative she jumps into his arms while he catches her with his quick reflexes. She wrapped her arms around his neck and her legs around his waist.

"Take me to your bed," she whispered hotly and locked their lips again. Harry sank his fingers into her bum to get a good hold before starting to walk towards his room to fuck his minx of a best friend turned lover into a babbling mess.

"Hmm… And you really think it will work?" Harry asked her. They were already into the second round of shagging when Hermione brought up the real reason why she came up into the boys dorm. She sneaked with his invisibility cloak, thanks to her status as girlfriend of Harry Potter, into the restricted section and found the book she was looking for.

But since they didn't want to stop fucking, Harry flipped her onto her hands and knees. He slowly thrusted with skilled precision into her, he bottomed out and hit her sweet spot behind her cervix. With one hand he held her waist while he balanced the book on her back. His slow pace let him read what she wanted him while he still could enjoy her warmth.

What he didn't count in was that he slowly and surely fucks her into oblivion. She couldn't form any words in response. The only intelligent sounds that came out her mouth were moans and gasps. Her mind was a puddle of goo. It was no wonder that her arms gave out and she fell face down into the pillow leaving her ass up. Harry lost the balance of the book.

"Hey… I asked you a question," he said. "You can't just collapse without telling me." When he only got moans in response, he closed the book and stowed it away. 'Oh well. It seems she is already too far gone,' he thought. He grabbed the top of her butt with both his hands and increased his pace. His thighs were hitting her cheeks, making them ripple hypnotizingly.

His balls started to swing and were hitting on her clit, making her see stars. She bit the pillow in front of her while her hands clawed at the sheets. Her eyes rolled in the back of her head when her next orgasm hit her like a freight train. Harry didn't relent with his thrusts, prolonging her high.

"Don't think we are done just yet," Harry growled. He felt her pussy fluttering around him, which let him know she came. "I am going to fill your greedy womb up and then we will talk about your idea there."

"Yes, sir," Hermione moaned instinctively. He increased his strength behind his thrust, setting a rhythm of clapping to her moaning. He loved how vocal she was in bed and gave his best to make her scream every time they shag. With every thrust, he pulled her bum towards him, his fingers sinking deeply into her flesh, slightly spilling around his fingers. He loved her bum. Just the right amount of firmness paired with the right amount of fat.

Harry would probably leave marks of his hands on her bum when they were done but he couldn't help it. It bounced so well every time he hit it and felt so soft and firm at the same time under his hands. He couldn't comprehend how he got so lucky.

"Fuck… I think, I am about to cum," he groaned.

"Do it. Inside, sir," Hermione shrieked. "Fill my little pussy up and make ME CUM AGA-IIIIN," she screamed at the top of her lungs. Harry was only a second behind before he sheathed himself fully, cumming deep inside of her. His balls drew up with every shot he was pumping inside of her.

He slowly pulled back when his balls were empty. With a small 'pop', his cock left her pussy. Thanks to his girth, her folds were left open widely while they clenched around nothing, trying to keep his cum in which slowly began to trickle in big globes out of her. He growled at this sight and left a firm spank on her bum, drawing a squeak from her. He lied down next to her and she instantly snuggled into his side.

Hermione draped a leg over his abs and kissed him. She quickly slithered her tongue into his mouth and started dueling with his but quickly lost and got pushed back into her mouth before he tried to push his down her throat. When they were out of breath, they broke their lip lock, staring deeply into each other's eyes. Sharing a smile, Harry rubbed his nose against hers drawing a giggle from her.

"Soo, now that your brain is working again, can you answer my question?" he smirked at her. Hermione blushed prettily.

"If you would have just stopped and let me explain it would have been all easier," she retorted without heat.

"Well, I could read quite alright so it wasn't me," Harry grinned cheekily.

"You are impossible," she huffed.

"But you love me."

"Yes. Yes, I do." She captured his lips in a loving kiss. "So what was your question again?" Harry chuckled.

"Do you think it works? Will that potion really make my cum nutritious for you?"

"Well, you still need to eat your food and the potion needs to be mixed with it. And only after you finish your meal will it be nutritious for me," she explained, looking pleadingly at him with her big doe eyes. Ever since that fateful day she dressed up for him, she got addicted to his cock and cum. She sucked it at least once a day out of his balls.

"Hmm," Harry hummed. "But how will it be mixed into my food?"

"Oh, that's easy. We just ask Dobby."

"Uh-huh. So you want Dobby to put a potion in my food, that makes my cum nutritious?" he asked with one raised eyebrow.

"Yeah. Can we? Please?"

"What is the worst what could happen?"

"It doesn't work and I only get dessert instead of a full meal for breakfast," she replied easily.

"And how do you want to do it?" Harry asked.

"With your invisibility cloak of course," she states as if it was obvious. "I slip under the table next to Ron, where you always sit and you come a few minutes later. And while you eat, I am going to prepare my meal."

"You thought this through already, right?" he smirks. "You probably even brew the potion."

"Yeah, well," Hermione looked sheepishly. "But I haven't talked with Dobby yet."

"Hmm, okay. We can try."

"Yay!" she cheered. She jumped into action and went to pull the curtains back before she heard Harry clearing his throat. She looked back at him.

"You might wanna get dressed first, love." Harry smirks, dropping a spank on her bum.

"Right." Hermione quickly dressed herself before kissing him again.

"I will wait for your report." He smiled to himself, letting his body fall back into the pillow.

Hermione woke up the next day feeling extremely giddy. She quickly dressed herself and got ready for the day. She went downstairs into the common room and sat by the fire. She pulled out a book from her satchel and started to read, waiting for Ron to come down. But she couldn't focus on the words. She was nervous and excited all the same. When he finally came down, he shook his head and greeted her.

"Good morning. Are you coming?" he asked.

"Morning. Soon." she replied, pretending to be lost in her book.

"Your loss." With that he went off through the portrait hole. Immediately after he was out of sight, she snapped her book shut and pulled out Harry's invisibility cloak. She hurried after Ron into the great hall. He went to sit down and she silently slipped under the table next to him where Harry usually sat. She applied a cushioning charm on the floor and waited for Harry to come down.

Harry, meanwhile, got ready after Ron left. After a refreshing shower, he went into the great hall and sat next to Ron.

"Morning Ron," he greeted his friend.

"Mwng Hawy." Harry rolled his eyes. Ron will probably never learn to don't speak with a full mouth. Instead he focused on his fixed plate which appeared right when he sat down. He smiled when he noticed all of his favorite food.

And then nimble fingers went to work on the buttons on his pants. He slightly leaned back, looking discreetly under the table. Hermione was kneeling between his thighs with the hood pulled back, leaving only her arms and head visible. She flashed him a grin and focused on her task. He subtly shuffled forward and caged his girlfriend in by surrounding her with his legs, so nobody could touch her accidentally and raise questions.

She got his cock and balls free then immediately went to work. She peppered kisses on it, slowly hardening it to its full length. She went down to his balls and started worshiping them too, popping them both into her mouth. It was a thrilling experience to suck her boyfriend's cock while no one was the wiser.

Harry started to dig in, trying hard to keep his composure. Hermione was going all in though. All of her daily blowjobs were paying off. She was suckling on his tip like it was a lollipop, trying to suck his cum straight from his balls without him even cumming. Slowly she took him in, deep into her throat looking up at him, shooting him a wink before massaging him with her throat muscles.

Hermione having the time of her life. Her thong was drenched with her juices while her empty pussy clenched around nothing. She quickly fell in love with this feeling of thrill cursing through her body. The choker Harry had gotten her as a gift was pressing down on the bulge in her throat. It always sat snuggly around her neck letting her know it's presence while it was made stretchy and more durable by magic. It was such a thoughtful gift from him.

She even could make it invisible which she normally chooses to do because they enjoyed their quiet from Hogwarts gossip. But it was always there sitting tight enough but not too tight to restrict her breathing. And when she took his cock down her throat, clamped down on the bulge, enhancing their both pleasures.

She pulled back to the tip and swirled her tongue around it when Ron spoke up.

"Hey, mate. Have you seen Hermione?" he asked. Harry froze.

"Uhm…" he said, not knowing what to respond.

"She was in the common room when I came down, reading a book already. Can you believe that?"

"She wasn't there anymore when I came down," he replied truthfully. To reassure himself he slipped a hand on top of her head into her soft curls, stroking her skull with his thumb. "But this sounds definitely like Hermione." He continued chewing on his food.

"Huh, I wanted to ask her out," Ron nonchalantly told him.

"What?!" Harry exclaimed.

"Yeah, mate. I have a crush on her, you know?"

"Oh." He didn't expect this. Absent-minded he quickly pushed Hermione's head down to his base in a possessive manner. She wasn't prepared for the sudden intrusion and made a wet 'Glurk'.

"What was that?" Ron asked.

"Something big," Harry faked a cough to cover Hermione nearly choking on his cock, "went down the pipe." Thankfully Ron was oblivious and clapped his back.

"You should chew more," he suggested, still unaware.

"Thanks." Harry said. "Anyway good luck with that, mate."

"Thanks. I mean have you seen her lately? Her ass mate. I don't know how she is able to hide it beneath her robe." Harry just hummed in return. In his mind, images flashed from their fucking yesterday. He remembered how he made it deliciously bounce and jiggle with his thrusts. He subtly started to fuck her throat on his cock.

Hermione was struggling to keep up with him. If it wasn't for their daily 'training' sessions, she would choke now loudly on it. He clearly got jealous if the slightly rocking of his hips, trying to fuck his cock harder down her throat was any indication.

"Seriously, mate. She went from a bookworm to a fucking bombshell."

"Language, Ron," Harry absentmindedly said. "You shouldn't talk so crass about your best friend." Ron just huffed.

"You are no fun." He started shoveling his food into his mouth again. Harry just rolled his eyes. He knew Hermione would never say yes to a date with him, if her choking on his cock underneath the table and her choker was any sign. He started to eat again, needing to finish his meal before he would come down her throat.

Hermione was doing her best to not make a sound. Harry's iron grip on her head was moving her up and down over every single big inch he had to offer. She made a mental note to flash Ron her choker but for that she needed to add some letters on it first and she knew now how she could rile Harry up and get another good fucking.

Harry pushed her down to the base and subtly looked down. He smirks at her tear stained face and mouths that he is nearly done eating. He pushed a little bit of magic in her choker, making it shrink a few millimeters. She choked on his cock, trying to get hold before she glared up at him without any heat. She knew that he knew she was loving this.

He held her down, her lips stretched around his base with her chin on his balls. Without a care in the world he finished the remainder of his plate and went to talk to Ginny about Quidditch. She couldn't move an inch back. She was stuck warming his cock as he started some small talk, but not with the boys. How dare he?

She pushed herself down a half an inch more on his cock, her nose now smushed against his abs with her lips now against his pelvis leaving only his balls free. She started to swallow around him frequently, trying to get her meal out of him that he was denying her. She slipped her tongue out and slithered under his balls, cupping them gently. Hermione heard him cough at the sudden sensation before he went on as though nothing was wrong.

Harry still didn't move her head. She started counting the seconds in her head. She slowly but surely was running out of her breath. After ninety seconds, she choked around him, she tapped him lightly on his thighs and he pulled her back. She took deep breaths around his head as quietly as possible.

She didn't know that Harry was just stalling time. The potion would let him feel when his system absorbed it. He started to move her head again on his cock, waiting for something to happen. When he was holding her down on his cock with her balls against her chin, they both felt his balls begin to churn. They grew a little in size and he felt them tingle. He started to thrust into her throat quickly before he buried himself to the hilt and started to feed her his nutritious cum.

Hermione knew the potion worked. His slightly bigger balls and the way his cock expanded in her mouth and throat were not the only signs. As deep as he was in her throat, she could feel the cum traveling through his cock before it blasted down her throat. His shots were bigger and longer. After already the third shot he came more than normally in one orgasm. She began to circle her clit, celebrating her success.

He was force feeding her his cum down her throat into her tummy. Her eyes rolled into the back of her head when she came while his cock was still in her throat. He was nearing his finish but his spurts came still strong. Each one makes her tummy swell a little more. Harry pulled her head back until only the tip remained inside. He shot his last few spurts into her mouth, each a mouthful which she greedily swallowed down, storing it to his other cum.

She noticed that even his flavour changed a little. There was a hint of sweetness with it. She loved magic. When he was done she let go of his cock, she gulped air into her lungs before she suppressed a burp. Looking back at his cock she saw the last of his cum slowly dripping from his slit. Latching onto it, she sucked like a straw on his cock, sucking the remainders out of his cock.

At that moment she knew she would brew this potion more often. She smiled satisfied when his balls were back to normal size. She kissed the tip of his cock before she tugged him back into his pants, tapping his thighs to let him know she is good to go. A few seconds later Harry got up and left.

Hermione covered herself with the invisibility cloak and slipped out from under the table. She went straight to the girls bathroom and locked it. Pulling the cloak off, she checked her appearance. She looked well for someone who just sucked her boyfriend's cock. Her eyes fell down to her blouse. The buttons were straining slightly against her skin. She smirks and turns sideways.

Her tummy was slightly distended from the amount of cum she had gotten fed. She rubs her hand over hand admiring the view in the mirror. She checked her watch realising she should get ready for charms. She freshed herself up, fixing the last touches on her appearance before she took her wand out. Her choker fades into view and she grins as she casts a surprise for Harry.

After she made it back invisible, she left the bathroom. On her walk to charms Hermione noticed that she shouldn't make sport quite yet. She needs to digest her filling meal. Smiling to herself she catched up to Harry and sat down in the back.

"Where were you?" he asked.

"Bathroom," she simply replied.

"Sooo, it worked, right?" She paused in getting ready for the period.

Professor Flitwick entered the classroom and started the lesson. Just after the lesson started, Hermione called out his name. He turned towards her again and instantly hardened in his pants. She made her choker visible for him, but that wasn't what got him hard. On it in golden letters said, 'Property of Harry's Cock'. Even after she made it invisible again, she suppressed her laugh at his state of arousal. This image was now burned into his mind for a long time.

He sighed to himself. This would probably be a long day of relentless teasing.
