Hermione felt drained. She had been laboring for two hours on her astronomy essay, and she still wasn't sure if she'd put Jupiter in the right place. She was worried she'd confused it for Uranus, and in the back of her mind, a small voice was telling her Professor Sinistra had said it was Mars. She groaned, rubbed her eyes, and looked around. The common room had slowly emptied as students drifted off to bed, planning to be well rested for the week ahead.

They all finished their work earlier, Hermione thought glumly. Why did I think this would be easy?

Her thoughts scattered as the portrait hole opened. She raised her eyebrows as she saw Harry climb through, squeezing his somewhat muscled frame through the tight opening...what? Hermione shook her head slightly. Harry was looking a lot taller than she remembered. Well, not taller, but it was like his posture had suddenly straightened and his build had expanded…

"You alright, Hermione?" Harry said, his voice interrupting her thoughts. He grinned. "You look distracted."

"I am a bit. You're wearing a tight shirt," Hermione said absently, considering the abs he must be hiding under his tie and button-down. Then she realized that her thoughts had slipped out of her mouth. "No, no, I mean I still have some night work," she offered lamely.

Harry suppressed a laugh. Hermione had a look on her face like she was just drinking in his body. The potion must already be working at full blast, he thought gleefully. Let's see how long Little Miss Perfect holds out.

"Maybe I can help you, Hermione," said Harry, letting some huskiness seep into his voice. This was going to be fun. He sat down opposite her and scanned the heading of her essay. "What is this? Astronomy?"

"Yes, I'm...ah…" Hermione tore her gaze from his chiseled face and playful green eyes. She'd never noticed how hot her best friend was. Against her will, she felt the heat of arousal begin to build between her legs.

"I'm trying to find Uranus," she mumbled, her cheeks reddening as her statement filled the room.

"My anus?" Harry chuckled, like this was an old joke the two of them had shared throughout the year. "I could point it out to you, if you want."

"No, that's not what I meant -"

"You wouldn't even need a telescope."

"Harry!" Hermione said shrilly, her eyes closing briefly as she imagined her hands around his muscular, toned ass. Oh god, she wanted him to caress her like that!

Harry couldn't believe how well this was going. But as fun as it was to tease Hermione in her addled state, he was quite impatient after two days of difficult potion brewing to cut to the chase - without the chase.

"Maybe you'd like fuck me, Hermione," he said, his voice dropping to be quiet but commanding. Her eyes met his, and he saw them widen in shock. "You want my cock inside you, you want my cum filling that tight pussy of yours, don't you?"

Hermione moaned under her breath as this imagery filled her mind. She did want it. Oh god, she wanted it bad. How did Harry know? He was just so hot and confident and she loved every second of it!

"Yes, I want you to fuck me, fuck me hard, Harry," she pleaded to the irresistible hunk before her.

"That's exactly what I wanted to hear, Hermione," he said warmly, beaming at her. Hermione felt strangely pleased, like she'd given him a present that he loved tremendously. Had he always been this charming? She tried to think back, but the only Harry she could remember was the one in front of her, relaxed and sanguine. The one she wanted to fuck into oblivion.

Harry swept her papers off the table. In another world, Hermione would have objected to this cruel treatment of schoolwork, but her homework mean exactly jack-shit at this moment. Harry leaned across the table and she arched her back up to meet him, their lips touching for the first time ever.

Why have I never done this before? she wondered as their mouths connected. It was so sweet, so glorious. Harry's lips were smooth and firm, and she moaned a little as she basked in the pleasure of it. She was conscious of a dampness between her legs, and her juices were beginning to seep through her panties. Harry broke the kiss, looking at her with a mixture of adoration and approval.

"I've waited a long time for this moment," he breathed, shrugging off his shirt and tie. Hermione had been right: he had an impressive six-pack and his pectorals were nice and big.

"How did you get so...buff?" she said unabashed, pulling off her cloak and skirt.

"The Room of Requirement," he said, unclasping his belt. "I just willed in a bench press and a sit up bench. And it gave me vitamin supplements, too."

"Vitamin supplements?"

"Yeah. Technically, they don't have any calories, and the Muggle government doesn't regulate them like a food. I guess that's good enough for the Room not to violate Gamp's Law."

Harry pulled off his pants. His boxers were straining to hide his erection. Hermione, halfway through undoing her bra, gasped. It was at least six inches, maybe six and a half - just as big as Dean's had to be, and that boy had a horse cock.

She pulled off her bra and tossed it aside. Harry surveyed his prize intently. C-cup breasts, on the smaller side but still plenty large. He circled around the table and embraced her properly, their lips pressed together in a fusion of passion. He reached a hand up and gently cupped one of her breasts in his hand, his thumb tracing circles around her pink nipple. Hermione moaned into his mouth at the unexpected pressure. Harry took advantage of her distraction to slip his tongue into her mouth, and he found that she delightfully challenged him for control. As they wrestled through the kiss, Harry gently forced her down onto the table. He used her new position under him to put both hands around her enticing orbs. He squeezed them, feeling the succulent flesh bulge through his fingers. Hermione kept moaning in pleasure at his harsh caress and he found it super hot.

Harry's arousal was digging into her stomach. Hermione could feel it, and she knew that soon Harry would pull away so they could begin the proper activity. Preferring to have at least an ounce of control over the situation, she broke the kiss, and reached her hands down to pull off the boxers of the Boy-Who-Lived. Harry's massive cock - six and a half inches at least - sprang to attention.

How can everything about him be so perfect? she wondered, staring at his cock with both amazement and desire.

"You've been kissing my lips, Hermione," said Harry decisively. Hermione shivered; she liked it when he took control like that. "Why don't use use that mouth of yours another way?"

Hermione scrambled to oblige her lover. She slid onto her knees and gently kissed the head of his cock. Harry groaned in ecstasy as she licked the underside of his length, before engulfing the tip of his cock in her mouth and circling it with her tongue. Harry braced himself against the table and let the waves of pleasure wash over him. His dick was sending him amazing feelings and he wanted to savor every millisecond of it. Hermione slowly slid her lips down his length, tongue tracing the central vein on the underside. Her mouth was slippery and tight at the same time, and she was gently sucking too, her mouth all around his member like a warm caress. Harry closed his eyes to focus solely on the sensations from his cock.

Hermione let it slip out of her mouth to take a big gulp of air, then braced her hands around Harry's firm, muscular ass. Slowly, she forced his manhood down her throat. She expected to have some problems with her gag reflex, but her body seemed just as willing as her mind was. Harry moaned a little himself as his shaft slipped down her throat. It was incredible, and he let out a slight whimper as she nuzzled him. She looked up at him, and he tussled her sweaty hair gently. Her glazed eyes looked up at him dreamily as she smiled around his thick cock.

Harry was happy enough with the blowjob, but he was eager to begin the main course. For a second he wondered if Hermione's skills were natural talent or the result of practice, but he dismissed it as beginner's fortune. Gently, he slid himself out of her mouth. Hermione pouted and looked reproachfully up at him as she lapped up a few drops of precum oozing from his member, which was painfully hard.

Gently, he lifted her up and pushed her back against the table so they were perpendicular. Hermione moaned as he traced his thumb over her slit, his touch just enough to stimulate, not satisfy.

"Harry, please, just do it!" she begged, her head rolling back and forth. Harry kept up the teasing touch as she squirmed underneath him, her sweet juices pouring over his hand as he slipped two fingers just barely into her folds. His other hand was firmly pressing her pubic mound, the smoothly shaven skin (the brazilian was a trend at the time) heaving under him. The simultaneous sensations of pressure and bliss overwhelmed her and she had a small orgasm right on the table.

"Jesus," Harry laughed as the sweet nectar of her body soaked his toying fingers. Her muscles twitched and her legs flopped under him as he continued to administer to her snatch. "You're more ready than I am!"

"Just...take me," Hermione gasped breathlessly. She didn't normally consider herself an extremely horny person, and she usually didn't push herself past three climaxes in her own private self-pleasuring sessions, but this situation was not at all normal and she was way hornier than she'd ever been.

Harry leisurely lined his dick up with her oozing snatch, rubbing his tip lightly over her throbbing lower lips. Finally, the last of his restraint gave way and he slipped his cock inside her. The feeling was incredible. Her walls were rough and tight, but wet and warm, and they seemed to grip his length as he pressed forward. As he sank inch after inch of his manhood into her love canal, the sides of her stiff cove seemed to mold to him, providing enough friction to be pleasurable yet still beckon him deeper.

Finally, he hilted himself inside her, their bodies touching as the head of his member massaged her cervix. Hermione eyes opened wide at the unexpected pressure. She could barely encompass his girth and he was only now bottoming out!

Harry took advantage of their closeness to kiss her one last time, then placed his hands over her breasts, her nipples poking out between his fingers. Slowly, he slid his cock out of her, almost to the tip, prompting a mewl of disappointment, which just as quickly turned into a gasp of pleasure as he thrust back in. The quick motions served to force most of her love sap out onto the tabletop, adding to the friction of his actions. Hermione groaned as she felt the stimulation in her cunt and Harry's massaging hands on her breasts. Her own hands spasmed and clenched by her sides as he ground her inexorably towards another peak.

"Hermione, I'm gonna cum," Harry said, his own eyes closed as he savored the feeling of her body around his length.

"Cum for me, Harry," Hermione said, wanting him to climax at the same time as her. She wrapped her legs around his waist and squeezed, forcing his thrusts to penetrate her deeper and harder. The intervals of pressure on her cervix and breasts were intense enough to make her gasp without being painful. Her hands reached up and clasped his, keeping their position on her tits. She could feel his lunging movements grow more erratic as he approached his own orgasm.

"Cum in me, Harry," she said, her voice soothing and low in spite of her own excitement. "Let that dick of yours pump me full of your seed. Give in, Harry. Empty yourself inside me."

The words had the desired effect. Harry felt the warm fire of climax cover his cock, the flames of lust peaking as he thrust one final time into her, and felt the relief as his seed, thick and viscous, coated the insides of her leaky fuckhole. Hermione came at the same time as she felt him pulse inside her. Harry pecked her on the lips, both of them too tired to make out properly.

Finally, he pulled his member, now soft and satiated, from her creamy snatch. He leisurely pulled some of his clothes back on, even though he would be going up to bed soon. Hermione made to do the same, but he stopped her.

"Lay down," he said, his voice like a delicate melody in her ears. "I like you like this," he decided, looking down at her as he circled the table. "Sweaty, panting, filled with my cum."

"This is how I like to be," Hermione assured him. She didn't know why, but something about Harry just made her happy to do what he wanted. It wasn't like he was controlling her; she just wanted to help him in any way she could. It made her feel...gratified in a way nothing else ever had. Maybe it was the afterglow of the orgasm...

"You've been a good girl, Hermione," Harry said, tickling her belly as he pulled his bag onto his shoulder. "Now you're going to go to bed, and you're going to sleep naked and just hope none of the other girls find out."

"Yes, Harry," she sighed happily, still too tired to get off the table. She liked it when he gave her commands. A command was like an instruction from a teacher: she just had to follow it and he would be pleased with her. Had his wishes always been this important to her? She couldn't remember.

"You did a very good job, Hermione," Harry said approvingly, and Hermione giggled as she basked in the praise. "You're my little concubine now, and in the future you're going to service me and you'll love every second of it."

"Yes, master," she said, leaning her head back to watch him walk up the stairs to his dormitory. There was something degrading about being called a concubine, she knew, but she really didn't mind as long as she was Harry's concubine. Wait, that wasn't what I meant, she thought, but it was okay. She'd been thinking something like that.

Slowly, she picked herself up. With the heat of passion gone from the room, her sweaty skin felt slightly cold. She gathered her things, carefully put her work away, and walked up her dormitory, still naked. As she got into bed, she replayed the whole incident, shivering in delight at how much fun they'd had.

Harry Potter wasn't just the big man on campus. He was the biggest man on campus.
