I don't own Harry Potter. This is the final chapter of this short story, and Merry Christmas.

Sex Night.

"Ooh, oooh, oooooh! Yes!" Holly panted and screamed as Theodore Nott fucked her from behind, the bed bouncing and creaking under the brutal, primal thrusts of Nott as he ploughed into her, again and again. The larger boy was on top of her, thrusting in and out of her pussy, while their joined organs squelched as he thrust in and out of her while she held on weakly as she felt the pleasure surging through her body.

Nott had his hands on Holly's hips, but occasionally his hands drifted down her soft hourglass curves, where he squeezed and massaged her tits and nipples.

"Zabini was right about you, Holly," Theodore panted, "you really are a slut."

"Mm, yes, I am," Holly purred. "I'm a little slut for you and other cock. I'm a whore for bad boy cock."

Holly had noticed Nott's stares when she and the other girls had left the dorms after the night before, and when she had lifted up her panties and smiled at him, she had noticed that Nott looked delighted and even hungry, and it was a look shared by every boy while the girls rolled their eyes and giggled at her, although a few of them had commented on her being a lucky bitch.

Slytherin's portraits had cleared up the mystery of what had happened to them very easily, really, although she was certain there was more to what happened than what met the eye, she also wanted to know what the drawbacks and the long-term consequences of sex night there were, but there was plenty of time for that.

But as she left the common room with the other Slytherins and they went for breakfast, Holly had noticed the way Nott and some of the other boys had looked at her and the other girls, and she knew that one of the consequences of sex night was Slytherin House was rather more brazen than the other three Houses combined, but she didn't care about them. Deciding to take advantage of the boy's lustful stares although she was hornier for cock, Holly had stared at Theodore and sat next to him throughout breakfast, and she had run a hand down his groin with her smaller, daintier hand before she had whispered, "I want you to fuck me after breakfast."

She had led her fellow Third Year back to the dorms, all the time swinging her hips and making sure he got the full picture. Once they had gotten back, she had given him a blowjob before they got on the bed, and they began to fuck

Holly screamed as Nott filled her with his cum again and she dropped weakly to the bed, panting while her body shone with a sheen of sex.

"Thanks, Theo," she whispered as she rolled out from under him and let him lay down next to her, panting hard, making her roll her eyes at his lack of stamina, "I loved your cock soo much!"

Theo grinned at her, his expression both roguish and crookedly mocking at the same time, "Thanks, Holly," he said as he gazed at her, looking at her pink lips which were still glossy somehow. Her chest was still heaving, glinting with a fine sheen of sweat that looked so enticing, and her body looked bronzed with the sheen, making it look far too good to be true; he and many of his dorm mates had known for a long time that Holly, like Daphne and Tracy, was one of the most prettier girls in their year; with her long raven black hair which was long and wavy which made her look even more beautiful, her pale skin which was almost milky; her emerald green eyes were big, bold, and so enticing while her lips were plump and perfect for kissing.

Just looking at her, gazing at him with a smile which was so soft was enticing. Theo gently lifted a finger and ran it down her long, swan-like neck and traced one of her large breasts, making her moan.

"Again?" She asked with amusement, already feeling a now familiar tightening in her midsection.

"Again," he nodded.

Grinning Holly, using a strength that stunned him, flipped him onto his back and she straddled him, stroking his cock as she did with her manicured fingers; the sharp, painted nails gently stroking his cock and testicles made him moan, and he was becoming more and more erect until his erection was nearly ready for her, while he felt Holly's weight on top. She leaned down and kissed his lips before moving all over his chest; by now, his erection was ready, and he was pulsing, ready to go.

Holly climbed on top while she slowly moved so she was right on top, slowly sinking down her pussy until it slid down, enfolding around Theo's cock like a glove fitting a hand. Once she got used to his thickness again, she began fucking him earnestly.

From where he was, Theo felt as if he had just died and gone to heaven as he watched the heavenly sight of Holly on him fucking him. His hands reached out and grabbed her big, defined ass. Holly might have been short, shorter compared to some of the other girls, but at the same time she made up for it by having big boobs and a big ass that was firm.

Holly moaned and panted as she rode Theodore like a horse.

"Ride me, whore," Theo grunted, thrusting his cock deeper into her tight cunt.

Holly rode him faster, panting while she pushed her own exercised body to its limits. She had gone out of her way to learn dancing thanks to the Room of Requirement, a treasure she had discovered in her first year after visiting the kitchens for some food; she had wanted to know if there was a large enough place in the school she could access easily, and exercise, and she had been told by the House-elves about the Room of Requirement, which had the added pleasure and advantage of providing her with whatever she wanted, giving her the chance to exercise; she had been taught dancing and even fencing to tone her body, and it had done wonders for her stamina otherwise she wouldn't be able to ride Nott the way she was.

After riding Nott for another few minutes, the Slytherin boy climaxed and shot his seed into Holly, who came a moment later. Holly weakly got off of Nott, and she stood up.

"Where are you going?" Nott demanded.

"I'm going, I've had enough fun," Holly gave him a wide smile. "But thanks for it. We'll definitely be doing this again." Picking up her wand, she summoned her clothes and cleaned some of the sweat off of her body before she put her clothes back on. She knew she would need to clean herself and get fresh clothes, but she had enjoyed the sex she had just had.

As she left, swinging her hips enticingly from side to side, Holly knew she was going to enjoy sex night from now on.
