Andromeda rubbed her thighs together, enjoying the feel of her thigh high stockings rubbing against her flesh as she observed Harry Potter.
She had tried to push the image of what he had done to Mrs. Dursley from her mind but involuntarily found her eyes drifting to his lips again. She felt another wave of heat flush through her groin and shifted her attention to the rest of her class, this was getting ridiculous!
She hadn't really considered herself sexually repressed until now, but once she got to counting, she realized it had been over ten years since Ted had last touched her, more fascinated with his accounting numbers than her body.
Now she didn't want to feel bitter at Ted, but the simple matter of the fact was that she had married him almost straight out of Hogwarts, still being a virgin to boot. Their sex life had been very basic and simple, something that hadn't really bothered her before. Seeing Mrs. Dursley in the throes of passion had shattered her world view, could a woman really feel like that?
Feeling her nipples sticking out like pencil erasers, easily visible through her thin shirt she realized her thoughts had been drifting again. Cursing mentally, she started correcting assignments while the children read, she needed to get her mind out of the gutter.
At least her plans to get to know Harry had gone well, their meetings had become an almost daily thing. She assumed he hadn't had much home schooling as he was behind on most school subjects.
This gave her a great excuse to keep him around after classes to work on subjects he was weak in. He really did make an excellent student, he paid absolute attention when she explained something, did everything as ordered and seemed to respond exceedingly well to praise.
His absolute obedience kept giving her flashbacks to last week when he had asked if she was 'stressed'. She had ignored his strange tone of voice then, but after getting an eyeful at their home she couldn't help thinking about what would happen if she should say otherwise now.
Harry clearly already saw her as an authority figure and obeyed her without question, leaving her slightly unsure on how to further cement her position of being in control of the future Lord Black. The fantasies she kept having when she glanced at his mouth made it abundantly clear what her libido wanted her to do.
Suddenly hearing the bell ring, she actually sighed in relief, her daydreams had left pussy wet again and she smiled happily as the kids bid her goodbye. As soon as the last one was out of the classroom, she hit the room with a silencing charm and placed a muggle-repelling charm on the door.
Andromeda had been feeling horny all day and could no longer contain herself, she couldn't even remember the last time she had masturbated but she simply had to get some release now.
After removing her jacket, she unbuttoned her shirt, revealing a generous D cup bust that was covered in a beige lace trimmed bra, which did nothing to hide her rock-hard nipples. She slid her hands up her taut stomach and lightly cupped her tits, beginning to gently roll her nipples in between her nimble fingers.
Feeling her pulse speed up, she unzipped her skirt, removing the restricting fabric and displaying a matching pair of silky beige panties and white thigh high stockings. Her excitement was showing as a large damp spot covering the entire front of her panties.
She slowly slid a perfectly manicured hand down over her smooth mound; hair removal spells had been popular among witches for hundreds of years before the muggles caught up.
Her breath sped up as her hand slipped over the soft folds, gently circling the moist lips and probing for entrance.
Dipping her long fingers into her pussy she brought some moisture to her clit and started to circle it with increasing pressure, causing a long breathy moan to escape her lips. Her fingers were slick with her wetness as they sped up, causing her breath to hitch as she inched ever closer to sweet completion.
It was to that scene one wide-eyed Harry Potter stepped into. The muggle-repelling wards had done nothing to slow him down and his knocking had gone unheard because of the silencing charm.
In his hurry to return to Aunt Petunia he had forgotten his bag again and was hoping to pick it up before Miss Brown locked the classroom for the day. His gasp of surprise was inside the silencing barrier, shocking Andromeda out of her fingering as her head snapped to him.
Having been raised to always be in control of her outward appearance, a necessity for a pureblooded woman growing up in Slytherin, her only obvious reaction was a deep flush that covered her cheeks.
Andromeda lifted an elegant eyebrow in obvious question to his barging in, not doing much to hide her irritation at having her orgasm ruined. She had been so close!
"And what exactly, do you think you're doing barging into my classroom Mister Potter?" Harry blushed as he realized he had in fact entered without permission, obviously interrupting his teacher.
The hard nipples, the musky smell and wetness that covered the front of Miss Brown's panties were obvious signs of what she was doing.
He had seen, smelled and tasted the same signs for well over a year and realized that Miss Brown had been trying to relieve some stress as well.
Aunt Petunia had told him that all women please themselves to relieve stress and the two he had met so far, Aunt Petunia and Aunt Marge had both been the same, so why not Miss Brown? Although he had to admit that Miss Brown was much prettier than both his Aunts'.
"I err, I forgot my bag and wanted to come and get it before you closed for the day." He stuttered out.
"And this gave you permission to enter my classroom at a whim?" She asked, her voice sounding like a whip.
"I'm sorry, I'm really sorry, but I can make it up to you Miss Brown!" She seemed very angry and Harry was terrified of what punishment he would get if he brought home a complaint, Aunt Petunia had told him she expected perfect behavior in school.
He had also always been told his place was to help Petunia manage her stress so why couldn't he simply do the same to Miss Brown?
Andromeda felt a strong twitch in her pussy at those words, she was still incredibly horny and the ruined orgasm had only heightened her lust. She was also very annoyed at the Potter child for interrupting her, further encouraging her to use him.
Flinging a locking charm at the door under the table she turned to him and said,
"Oh, and how would you do that?"
Her breath hitched as he quickly dropped down to his knees and crawled under the desk, coming up to her soaked panties. Feeling practiced hands grab onto her panties she automatically lifted her hips, watching the boy slide them down her long legs.
Harry showed no hesitation as he moved in, softly moving his tongue over her soaked folds. He found she had a familiar musky taste, with surprisingly sweet overtones and quickly started lapping up the mess she had left, licking the soft flesh while moving his hands up to help spread her puffy lips.
As she opened up, he dove in, burying his nose in her clit and swirling his tongue around her hot wet hole. Using the flat of his tongue he would run it up and down the walls of her pussy, probing into every crevice his mouth could reach, occasionally taking her puffy lips into his mouth to suck on.
He was surprised at how wet she was, he had to constantly swallow and slurp as she flooded his chin, a rosy glow spreading over her skin as she spread her legs even wider. Every lick and suck seemed to cause a small spasm in the soft flesh, her heat and heartbeat increasing the more he feasted on her pussy.
Her fluids were running down to her anus, forcing his tongue to dive in after them, licking the pliant flesh between the pussy and butt while occasionally delving into her musky hole.
Andromeda was in heaven, she had to be. Never in her life did she think anything could feel this good. The boys' hot tongue seemed to dance over her folds, teasing and enticing nerve endings, massaging the flesh and heating her core with every lick.
Nothing her hands had ever done came close, hell nothing Ted had ever done came close to the absolute bliss she was experiencing. She fumbled with her bra, freeing her breasts and lightly pinching the nipples as she massaged her silky skin.
Any guilt she had been carrying around evaporated as she felt his lips circle her clit, sucking gently while teasing it with his tongue.
It was simply too much and she saw stars flash through her eyes as she roughly grabbed his hair, grinding his face into her pussy.
He was clearly familiar with the reaction as this only lead to him speeding up further, dragging his hot tongue over her wet nub, making her legs quiver and breathy shouts escape Andromeda's lips.
"Oh god, oh god, oh god, eat it all you dirty boy! Ahhhhhhhhh that's it, that's iiiiiit!"
After spending over a decade in forced celibacy her orgasm almost knocked her out and caused Harry to swallow desperately lest he be drowned under her juices. Her stocking clad legs wrapped around his head, framing it in white lingerie as she tried to control her flailing limbs.
Harry was surprised at the vice-like grip her shapely legs held him in, crushing his face to her soft sopping mound and making it hard for him to breathe as he felt her drag her pussy up and down his face, wringing the last bit of pleasure out of his mouth.
Finally feeling the pleasure abate Andromeda relaxed her grip on Harrys' hair, enjoying the soft kisses and lapping he was giving her oversensitive pussy, sending out small shock waves through her body. The feel of his soft tongue running up and down her thighs, cleaning up her mess, was absolutely divine.
Harry hoped he had sufficiently placated Miss Brown as he did not want to bring home a complaint to Aunt Petunia under any circumstances. Just to make sure he also added,
"If you need a toilet, I am also available Miss Brown." Andromeda was still trying to regain her breath when she heard his words, causing her brain to short out.
When she pieced together what he meant she almost swallowed her tongue, she had never even considered using someone like that. The thought was definitively delightfully dirty and the power over him such a position offered was very enticing.
Looking into the expectant eyes of the future Lord Black she, however, decided this was enough for today, anymore and she wouldn't be able to walk straight.
"No thank you Harry, not today."
Pleased she wasn't calling him 'Mister Potter' anymore he still had to make sure,
"Will you be sending a complaint home Miss Brown?"
Seeing the worried eyes of the boy in front of her she understood he was worried about how Mrs. Dursley would react to a complaint. Smirking she realized this actually gave her a great opportunity to get some lasting power over the boy.
"No, I will however place you on probation. You will be spending time with me after the classes are over and you will be helping around in my classroom during recess. Now get going before your Aunt gets worried."
Relieved he quickly nodded, grabbed his bag and almost flew out the door with a "Thank you Miss Brown!"
Andromeda slumped in her chair, feeling better than she had in years as she realized this assignment of hers was actually turning out to be a lot of fun.
