Petunia felt herself being slowly woken up from a pleasant dream, feeling a shimmering wet heat in her groin. As she came to, she recognized it as the same feeling she had experienced every morning for the last two weeks, a small warm tongue lapping gently at her folds.
She smiled contently as she stretched her arms behind her head, spreading her legs wider to give her little toy better access. The freak had been an absolutely fantastic little alarm clock during the time Vernon was out of the house and she was definitively going to miss these divine mornings.
When Harry saw his Aunt's, legs move around his head he realized she had woken up and started using his hands to spread her pussy as his tongue delved deeper into her musky hole. He used deep long licks, making sure to swallow in between. He had left a stain on her sheets the first morning, which had greatly angered his Aunt.
After being asked if he considered himself too good to swallow what she was offering she had twisted his ear and forced his head down to the sheet, having him lick the fabric for the next fifteen minutes while painfully twisting his hand behind his back. There had been no more stains after that.
Hearing her quickening breathing and feeling a hand on the back of his head Harry redoubled his efforts, focusing his mouth on her clit.
This made her moan loudly and he soon felt her hump his face in obvious pleasure before she suddenly wrapped her thighs around his head, shaking like a leaf and flooding his mouth with her juices. Recognizing her orgasm for what it was, Harry dutifully swallowed everything and made long gentle licks as he had been taught, cleaning her slit.
"Toilet."
He heard the now familiar command and quickly complied, wrapping his lips around her piss hole and soon felt her sour tasting warmth flooding his mouth, forcing him to gulp it down as quickly as possible to avoid leaks.
Swallowing her piss had left his stomach feeling queasy for the first week but it did not seem to bother him to the same extent anymore.
Feeling the steady stream abate he sucked out the last few drops then rolled his tongue around the hole to make sure it was clean, followed by a few wide licks all over her slit to make sure nothing had leaked out.
Feeling refreshed Petunia sat up and removed the sheet hiding the freak from view, seeing a spotless sheet she allowed a wide smile to grace her face,
"Mmmm very good my little alarm clock, not a single drop spilled, I will miss these mornings."
Harry blushed lightly under the rare praise which only made her smile wider.
"Don't let it get to your head freak, that's when you start being sloppy, forcing me to discipline you!"
Making it sound like it was Harry's fault that she had to punish him was obviously intentional on Petunia's part and it had greatly helped in his obedience. After all, the freak didn't really need to know that she quite enjoyed watching him squirm.
After sending a now humbled Harry to prepare breakfast the Dursley household continued their day as normal, or as normal as the Dursley household ever was.
It was during dinner that Vernon arrived, obviously slightly tipsy but in a very good mood.
"Great news pet! I have been sent to represent Grunning's drills for the Expo in London next weekend!"
"You will be joining me as my wife to help entertain the possible clients, this is a great opportunity to show those idiots at Grunning's just what kind of a salesman I am!"
Petunia was less than pleased; the weekend was two days from now, leaving her little time to prepare.
"What about Dudley?"
"Oh no worries pet, I already spoke to Marge and she's happy to take care of him over the weekend. Not to mention she'll keep the other one busy as well."
The distaste in his voice was obvious when he mentioned 'the other one'.
Further annoyed at him going behind her back Petunia had little choice but to comply, Vernon seemed immune to any complaints about his 'beloved sister Marjorie'. At least she would keep the freak busy, her dislike of him was well known in the Dursley household.
Sighing Petunia complied and started mentally cataloguing everything she might need to look presentable at the Expo.
Friday soon arrived, as did the imposing figure that was one Marjorie "Marge" Dursley, bustling through the front door and instantly engulfing Dudley in a huge hug. Ripper followed soon after, already growling and homing in on Harry.
Petunia insisted they leave quickly as she had little interest in listening to Marge complain about her 'deadbeat sister' again.
After showering Dudley with the usual bag of gifts, Marge turned her attention to the little freak, standing near the stairs staring at the floor.
"Boy! Move my things into the guestroom and unpack them, then unpack Ripper's things in the kitchen! Move!"
The boy moved quickly to fulfil her orders, surprising Marge as she was used to receiving a defiant glower or some muttering under his breath. Pleased that it seemed that Petunia had stepped up her discipline regarding the whelp she turned back to spoiling Dudley.
Once her things were unpacked, she had the freak prepare dinner, once again pleased at the lack of hesitation he showed when obeying orders. Even Ripper seemed to be less hostile towards him and the first word that came to her mind when observing the boy was... 'submissive'.
After dinner she laid Dudley down for his nap and had Harry perform various chores of her choosing, much to her surprise he still showed no defiance whatsoever.
She was certain he would snap at her when she ordered him to clean the toilet bowl with a small hand brush yet he once again quietly went about his work.
Little did she know Harry was intimately acquainted with the bowl, having been forced to lick the seat by Petunia when he let some of her fluids dribble on the couch earlier in the week, thus having to use a brush was really nothing special.
Marge was puzzled, she was a dog breeder herself and if she didn't know better someone had extensively 'trained' this boy, as his attitude seemed to have greatly changed since she last saw him. Ordering him to prepare some tea for her she sat down at the table,
"So boy, it would seem Petunia has finally decided to teach you your place."
She thought she saw a brief flash of surprise flit through his eyes before he quickly nodded. Intrigued she decided to explore a bit deeper,
"What all is it that you do around the house, it seems you are finally being useful seeing as they decided to let you have your own room?"
Harry was very unsure of what to tell her as Petunia had specifically said that things that happen within the Dursley household should stay inside the Dursley household. Marge was a Dursley however so he was afraid of lying to her.
Tentatively he started describing his chores, starting with the basic work he did around the house.
Marge hummed as she sipped her tea, listening to the boy describe his work until he mentioned 'helping his Aunt relax'.
"What was that boy? Helping Petunia relax?"
"I, err, please her as I have been taught. Aunt Petunia says all women have a great deal of stress and my job is to help alleviate her burden" Harry hesitantly replied.
Marge was very intrigued now, what all could Petunia have had that little freak do. Vernon was no doubt in the dark about this.
Her curiosity over what Petunia had been teaching him helped her make up her mind, putting her cup of tea down she simply said,
"Show me."
Harry froze for a split second before crawling under the table; almost six months of instant punishment whenever he hesitated to please his Aunt had made him quick to obey all order regarding his special chore. Moving his hands under her long skirt he quickly reached past her plump thighs and grabbed her panties.
Marge was so surprised by his sudden actions that she acted almost on autopilot, lifting her hips and letting the boy pull down her panties.
Harry gave her a brief glance of hesitation before doing as he was told, moving his head under her thick skirt.
Marge unlike Petunia was not shaved; however, she had fairly sparse hair around her much plumper pussy. He used his small hands to help spread her and started making long gentle licks up her slit.
Marge snapped out of her shock as she felt a hot tongue move up her nether lips, which much to her surprise felt very good. Not having had physical contact in decades, not to mention considering herself far too proper to ever ask anyone to perform oral sex on her she was floored by the sudden sensations spreading through her body.
Without even thinking about it a small moan slipped past her lips as she spread her legs wider and moved her hips closer to the edge of the chair, giving Harry better access to her pussy.
Harry used to seeing this reaction started flicking his tongue deep into her pussy, lapping at every nook and cranny and dutifully swallowing. Marge had a sourer taste than Petunia but he didn't let it affect him, as he had been punished enough times to not show any hesitation when pleasing her.
Soon he moved over to her clit, encircling it alternatively with his lips and tongue, giving gentle sucks and kisses all over her sensitive nub.
Marge couldn't believe the pleasure she was experiencing; Petunia had clearly been training the boy for a long time. When she felt his lips around her clit again while his tongue lapped at it, her orgasm hit like freight-train and she shuddered all around the boy's head, roughly pulling him into her pussy.
He showed no signs of being affected by her roughness and continued lapping at her sensitive flesh. Gasping for air and shuddering with aftershocks she pushed his head away, yet when he pulled back, she was very surprised to see both the chair and skirt being dry, the boy had swallowed everything!
The boy stayed on his knees in front of her clearly awaiting further orders. Gulping in deep heaving breaths Marge tried to compose herself, that had felt incredible.
"Is... is that all you do for your Aunt?" She asked breathlessly.
Seeing the boy hesitate briefly she snapped at him,
"Well! Out with it, if you lie to me, I'll take the cane to your buttocks boy!"
Clearly intimidated by the sudden threat Harry responded,
"No, uh, she also likes to use me as a, uh, toilet after pleasing her."
Shocked at Petunia's perversion Marge felt her jaw drop as she stared at the little boy. She did however have an overwhelming urge to pee herself after the treatment her pussy has just gotten, so she couldn't help the smirk that now replaced the gaping expression.
"Well then, get to it!"
Pleased to see the boy crawl back under her skirt she soon felt lips clamp around her pussy and slowly started to let loose into his willing mouth.
When her bladder emptied, she was delighted to feel his tongue cleaning up her pussy again, while he sucked out any fluids that were left behind.
"Boy, I think this weekend will be most interesting."
Had Harry seen her expression he would have shivered.
