Challenge fic for fluffy-fanfic-lover. The first chapter is a little short but the later chapters are longer I promise.

Harry sighed as he continued emptying out his trunk. He couldn't believe he still had to come back to Privet Drive every summer. Why couldn't he just go straight to the burrow? And then he spotted it underneath his robes. It looked like an ordinary journal but Harry didn't keep a journal. Where did it come from? Suddenly he remembered he had found it in the department of mysteries but he had been so focused on finding Sirius he hadn't had a chance to see what it was. Opening it up he saw something written on the inside cover "Whomevers name is written shall hence be forced to obey every order of the owner of this journal" It reminded Harry of a muggle anime he had seen. But this was ridiculous there couldn't really a book that would force someone to obey you, that would be worse than the Imperius curse and that was illegal. Still this book gave Harry an eerie feeling, couldn't hurt just to try.

Harry grabbed a quill and tried to think of the one person least likely to obey him. The cat flap near his door rattled as his aunt pushed a bowl of cereal through it. Of course. Harry loaded his quill with ink and wrote "Petunia Dursley" in the journal. And then an even crazier thought occurred to him. He wasn't sure if it would work but he added "in her sexiest lingerie." after his aunts name. He waited eagerly for a few minutes but nothing happened. He knew that journal was bogus. He tossed it back in his trunk.

Several hours later his aunt entered his room wearing a large coat. "Going somewhere?" Harry asked. "No." Petunia replied. "Then why are you wearing that?" "Vernon went to work." she said calmly. Harry shrugged. "And Dudders is with his friends." "So?" She dropped her coat to reveal a black and red lace corset with a matching thong. "So that means we're alone." Harry sat bolt upright. "Aunt Petunia?" he said cautiously. He was surprised he didn't think it was possible for his horse faced aunt to look attractive but in her corset she looked stunning. "What do you want Harry?" "I-I-I want to fuck you." he stammered. "Then do it."

Remembering what the journal said Harry cleared his throat. "Get over here and suck my cock." Harry's aunt knelt in front of him and unzipped his pants and pulled them down along with his boxers. His cock was already hard at the thought of fucking his aunt. "You're much larger than Vernon." she purred before deepthroating him. Harry gasped. He had never had anyone go down that far that fast but his aunt was a pro. She slid her tongue all over his cock while one of her hands massaged his balls. Harry never experiencing a blow job so perfect and he did not last long. "Aunt Petunia I think I'm about to cum." he expected her to release his cock but instead she dove even deeper so that her nose was pressed right against his pelvis. She gave one final squeeze of his balls and he exploded in her mouth. "Swallow it slut!" he ordered and she immediately did as she was told.

She pulled her mouth away awaiting more orders. Knowing it would take a few minutes before he was hard he decided to explore her body. "Stand up." he said. She really did look amazing. There wasn't an ounce of fat on her body. He pulled down the cups of her corset to reveal her tits. They were tiny but perky, and besides Harry didn't mind the small ones they were bite sized. Harry captured one in his mouth. It was so easy to fit it all in his mouth. He groped the other one for a few minutes listening to his aunt moan. After he was satisfied he pulled down her thong. Her pussy was bare and looked positively delicious. "Would you like me to eat you out?" he asked. "Only if you want to." "I want to."

He had his aunt lay on the bed while he crawled between her legs. Using two fingers to spread her labia he admired her little clit. He reached out a finger to stroke it and noticed his aunt flinch. It had been awhile. This would be fun. Wasting no time he dove in attacking her clit with his mouth. He used his hand that wasn't holding her open to pound into her. Even after giving birth to the very large Dudley she was very tight. He couldn't wait to feel it around his cock. His aunt was screaming at the dual assault on her pussy. Harry was sucking on her clit while his fingers remained at a constant rhythm inside of her and honestly she had never felt anything better. Vernon Dursley was no stud.

Harry wasn't sure if it was his aunt screaming in ecstasy, the taste of her delicious pussy, or a combination of the two but he was hard again. However Harry Potter was not a selfish lover and was determined to get his aunt off first. A task made easier by the fact he was an expert at oral. Swirling his tongue around her clit while he sped up his fingers his aunt bucked against his face a few times before she started shaking from her orgasm. "Oh fuck! Harry! Fuck that's so fucking good! Ahhh!" Harry waited for his aunts orgasm to subside before he kissed her. He shoved his pussy soaked tongue in her mouth determined that she should taste herself. His aunt willingly took his tongue and sucked her own essence off. Pulling away from the kiss Harry looked directly into her eyes. "I'm going to fuck you now."

Harry was nervous. He had never fucked someone so much older and more experienced than him before. Keeping his eyes locked on his aunts face he slid slowly inside of her. She shut her eyes and bit her lip but a moan still escaped her. That was all Harry needed. He was already pounding into her fast. He wanted to make it last but damn he just couldn't resist her. "How does it feel slut?" he asked pawing her small tits. "Amazing." she moaned. "Look at me." her eyes flew open at these words. "Do you want it harder?" he asked. "Only if you want to." "Say it!" "Harder Harry! Harder!" Harry picked up the pace jack hammering into his aunt. Harry was moving so fast the bed was shaking ominously but he really didn't care. "Fuck Harry! That's so fucking amazing!" Petunia screamed. Harry reached down and started thrumming her clit in time to his fucking, before long his aunt was writhing under him with the most powerful she'd had in years.

Harry didn't stop strumming her clit until he was sure her orgasm had passed. But he did pull out his still hard cock that was covered in her juices. "I want you on top this time." Petunia flipped Harry over like a pro and climbed on top. In contrast to Harry she started off at a slower pace easing herself into it. Harry decided that just this once he would let her get away with it. He had to admit watching his aunt bouncing on his cock was one of the best things in the world. Even better was the way her pussy squeezed his cock every time she went up. He wouldn't last long like this. "Fuck Petunia, how did you get so good at this?" he asked pinching her nipples. "Must be natural talent. Your uncle doesn't fuck me enough for decent practice." "His loss. This pussy is incredible!" Harry started thrusting up to meet his aunt whenever she came down.

Before long Petunia Dursely was hurtling towards her third orgasm of the night. "Not yet slut!" Harry growled. "Don't you dare cum without me!" And with the skills of a much younger woman Petunia spun on Harry's cock until she was facing away from him. Now Harry had a perfect view of his aunt's ass she continued fucking herself on his prick. Watching her ass bounce on his cock and listening to her desperate moans to cum Harry let loose. "Fuck!" he screamed jerking up against her and spraying his seed inside of her. Feeling her nephew cum Petunia also let loose screaming like a banshee.

After what felt like years Petunia rolled off of Harry's cock and laid down next to him. His cock was soaked in his aunt's cum. "Clean my cock." he said simply. Petunia took special care to lick every part of his cock she could. "One more thing Aunt Petunia. Make me a sandwich." Petunia made to stand up but fell over immediately as her recent orgasms had rendered her legs unusable. Harry watched as his aunt had to crawl to the door and through the landing. He was going to enjoy this journal.
