Later that night, Hermione was in the library looking for a book on the Goblin Revolution of 1245, when she heard him again.

"You should get a muzzle for that boyfriend of yours, Granger." Malfoy smirked as he leaned against the bookshelf next to her.

She ignored him and continued to look for her book.

"I could teach him how to respect his superiors if you want." He sneered and Hermione spun around and pushed her wand against his throat.

"Don't even bloody think about it, Malfoy. You do anything to him and I'll make you regret it." She spat angrily at him causing Malfoy to laugh at her.

He glared down at her. "Please, Granger, your bite isn't so big either." He rolled his eyes and Hermione had no idea what drove her to do what she did next.

If anyone were to ask her why she did it, she probably would have blamed it on lack of sleep. She glanced at his shoulder where his skin was showing due the fact that the two first buttons on his shirt were undone and latched her teeth into his skin. She bit down hard onto his shoulder standing on her tiptoes in order to really sink her teeth into him. She heard him gaps in shock. She bit down until she tasted blood. She heard him moan and that seemed to snap her out of her moment of insanity. She unlatched herself from, Malfoy. She slowly lowered herself back onto the sole of her feet and looked up at him. He watched her for a second with confusion before glaring down at her.

"You shouldn't have done that, Mudblood." He said before slamming her against the bookshelf.

She fought him against him as she shoved him off her but he just threw her to the ground. She hissed in pain as she landed on her shoulder. He pinned her down against the floor straddling her and holding her arms above her head. He glared down at her before grabbing his wand and whispering a spell that had the buttons of her shirt snap open. She glared up at him.

"Let me show you just how big my bite really is, Mudblood." He growled before latching his teeth to the swell of her left breast.

Hermione whimpered in pain as he bit down hard. She could feel him drawing blood and struggled against him but he pinned down with his lower body. She could feel how hard he was and moaned as she felt him against her. He stopped biting her and looked up at her. He frowned and moved his hips against hers again causing her to moan loudly. He smirked lightly before taking one of his hands off her wrists above her head and used it to trail it up her thigh. She stared at him and he stared back at her. Blue met brown and Hermione let out a yelp as his thumb found her clit. He rubbed small circles and watched her writher beneath him. She bit back down on his neck as he slipped two fingers into her. She hissed as he pumped in and out of her. Was she really letting him do this to her? Gahh….Oh yeah she was, she thought as he hit her G-Spot. She moaned and when she looked back up at him his eyes went from a dull grey to a steel color that made her stomach drop.

"Why the fuck do we still have clothes on?" He growled before tearing at his shirt.

Hermione followed his lead and tore of her shirt. He stared her green bra and raised an eyebrow. She shot him a glare and unhooked it leaving it fall off her. He stared at her for a moment before latching onto her right nipple. She whimpered as she worked to get his pants off as he worked on her skirt. Finally, they were completely naked except for their socks and Malfoy without any warning thrust into her causing her to scream. She felt his hand slam onto her mouth.

"Fuck, Granger! Do you want to wake up the whole bloody castle?" He hissed in her ear as he pumped in to her.

"Fuck you, Malfoy." Hermione muttered as she turned them over.

Malfoy growled and turned them back over. "I'm on top!" He snapped and she rolled her eyes as she rolled her hips causing him to moan into her neck.

"Bloody hell, Mudblood your killing me." He whispered into her hair and she smirked.

"I'm…I'm gonna…" Hermione whimpered as she felt herself coming to her edge.

"Don't let me stop you, baby. Cum for me." He whispered in her ear and hearing Malfoy calling her baby brought her out of her lust crazed daze and she pushed him off her.

He glared at her as she started gathering her clothes. "What the bloody hell, Granger?" He growled as he got up still hard.

She frowned ignoring him and started getting dress. He approached her and slammed her against the bookshelf.

"You just gonna leave me like this?" He asked gesturing to his hard-on.

Hermione bit her lip and frowned. "Yes." She said before throwing on her shirt.

"Wow…" She heard him mutter to himself.

He mumbled a spell and she look down to see that he was ermm normal again. He started getting dress too and as she was about to leave he called out.

"Granger!" She turned to see him buttoning his shirt.

"This…" He said gesturing to the space between them before opening his mouth to speak once more but Hermione cut him off before he could finish. "Never happened nor will it ever happen again." Hermione said and Malfoy nodded.

"If anyone ever found out, they cut off my dick and bloody crucify me." He muttered lowly causing Hermione to glare at him.

"It's not like I am going to tell anyone, Malfoy. I don't think I'll be able to look at myself in the mirror again let alone tell anyone about this. I feel disgusted with myself." Hermione replied angrily causing Malfoy to glare.

"Hey if anyone should be disgusted it's me, for Merlin sake, forget them cutting my dick off, for all I know it might just rot off after being in your muddy cun…" Slap!

Malfoy looked murderous after she slapped him but she did not regret doing it.

"Stay the hell away from me, Malfoy." She snapped.

"I plan too, Granger!" He yelled before stalking past her.

Hermione took a deep breath and slowly fell to her knees and cried. She had cheated on Ron…with Malfoy.
