"No! Keep fucking me!"

"NO!" shrieked Harry passionately, "Keep fucking me!"

"GOOD ANSWER!" roared Uncle Vernon and his visceral response had Harry almost immediately regretting her impassioned plea.

PLAP! PLAP! PLAP! PLAP! PLAP! PLAP! PLAP! PLAP!

"Ah! Ah! T-Too rough! Please, M-Master! S-Slow down! Mmh!"

Never in a million years would Harry have thought her fat bastard of an uncle to be capable to move at the speeds he was currently pounding her asshole at. Not without the motivating prospect of food, at least. While the sensation of the cock inside of her felt great, the fact that she had over two hundred pounds of flesh slamming her repeatedly into a bed was making the rest of Harry's body rather sore. Were it not for the innate sense of toughness that all witches and wizards seemed to possess, Harry would've been rather concerned about having suffered rather severe spinal damage by now.

Though it wasn't like Uncle Vernon seemed to care.

SMACK! SMACK!

"YOU'LL TAKE WHAT I GIVE YOU AND YOU'LL LOVE IT!" screamed her Uncle, spanking each of Harry's ass cheeks so hard that she was sure they'd bruise and bringing tears to her eyes. Her tears flowed freely down her face when Uncle Vernon yanked her up by her long crimson locks to continue his verbal tirade, "THIS IS WHAT WOMEN ARE MADE FOR, YOU STUPID WHORE!"

"I'm s-sorry-Ack!" Harry's fearful apology in the face of her uncle's familiar wrath was cut off as one of his meaty hands clasped itself tightly around her throat.

"YOU WILL NEVER TALK LIKE THAT TO A MAN_ EVER _AGAIN! DO YOU HEAR ME?!"

Harry's tactile sense greatly heightened itself as her uncle choked her, to the point that she could feel where every droplet of spittle born from her uncle's furious shouting land on her skin. It was a terrifying experience and one that brought back a memory of Wormtail attempting to strangle Harry with the silver hand Voldemort had gifted him with. But unlike that moment, something about Harry's new body caused her to react with both fear _and _arousal of being dominated like this. Her uncle was firmly in control of both himself and Harry and wasn't fully cutting off Harry's air supply despite how large his hand was and how slender Harry's neck had become.

'Merlin, what's happening to me? And why don't I want it to stop...?!'

"I...I won't...!" Harry managed to **** out.

"Swear it." hissed Uncle Vernon, no longer yelling and was thus much scarier ('And arousing.' she thought shamefully). "Swear that you'll never go against a man and let him do what he wants with you."

The hand around Harry's throat relaxed slightly, allowing her to speak more easily, though it remained where it was as an implicit threat. "I swear..." began Harry in a rasp, "That...I'll never go against a man and...let him do what he wants with me..."

"Again!" demanded Vernon.

"I swear...that I'll never go against a man a-and let him do what he wants with me." An odd electrical tingle that Harry associated with magic usage seemed to ripple across her skin when she repeated her degrading words a second time. She wasn't given much time to ponder the phenomenon when Vernon ordered her to repeat it for a third time.

"AGAIN!"

"I swear that I'll never go against a man and let him do what he wants with me!"

Click!

An inaudible sound, as paradoxical as that seemed, reverberated within Harry the second the last syllable of her oath left her lips. Something invisible seemed to drape itself over Harry and sink into her body and constrict her like a particularly snug blanket. However, when she focused on what felt like a very watered down Imperius, the sensations seemed to vanish as if they were never there.

'What just-?'

Plap! Plap! Plap! Plap! Plap! Plap! Plap!

Harry abruptly lost her train of thought when her uncle resumed fucking her ass at a frenetic pace once again. Her powers of concentration suffered another blow when Uncle Vernon started to **** her again as well. Much like before, Harry became hyperfocused on physical sensations and the cock in her ass felt even _better _than before. Uncle Vernon seemed to be saying something, though Harry had a difficult time focusing on exactly what he just said, barely able to do more than moan like a strung-out whore. The cock in her ass stuttered for a few seconds and she felt her uncle's body begin to shake. It took her brain a few moments to process that he was laughing and she gasped when his hand left her neck.

"Love the way you squeeze me extra tight when I start **** you. And considering how much your cunt is leaking, you seem to enjoy it even more!" cackled Uncle Vernon. "'Course, it's hard to properly break you in with only one hand. Face down on the sheets, whore and spread those cheeks."

The invisible constricting sensation made a return and Harry found herself automatically obeying the order as she focused on the magical effect.

'What the bloody hell was THAT?!'

"Much better, whore!" chortled Uncle Vernon, patting Harry's head like she was a particularly clever dog. His laughter trailed off into something darker and he added in a dangerously silky tone, "Just remember to shut up and take my cock like a good girl or I'll have to punish you."

Harry was about to submissively reply with a "Yes, Master" when the magical effect made it's appearance again and seemed to clamp Harry's vocal cords shut. She felt like she could push through the spell if she wanted and was about to do so when her uncle let out a satisfied snort.

"Seems like my little slut is finally learning to keep her mouth shut. Good."

'"An everlasting compulsion is borne with an oath that is thrice sworn."' Harry's eyes bulged when a random memory of Hermione forcing her and Ron to study one day at the library after the fake Moody's lecture on the Unforgiveables swam to the front of her mind.

'Bollocks!'
