Over the Line

Ginny opened the door to the Transfiguration classroom and looked inside. Empty, as expected, save for a small melon on each of the desks that were lined up in front of the teacher's desk. She gave the corridor behind her a glance, making sure nobody saw her, and then sneaked inside. She checked her watch and closed the door; locking it from the inside with the spare key Professor McGonagall had given her earlier that day. She then quickly hurried over to the teacher's desk, crouching down next to it and inspecting it. Five drawers on each side of the desk and a big empty space in between, now occupied by a plain wooden chair without armrests. Ginny dragged the chair out a bit and crawled underneath the desk. After sitting up and leaning backwards against the back of the desk she pulled the chair back. And waited.

Ginny and Professor McGonagall had agreed earlier that week to do something out of the ordinary for a change. Professor McGonagall liked the idea of doing it where there was a slight risk of getting caught, and Ginny had immediately suggested the classroom.

She was going to sit underneath McGonagall's desk for an entire class, doing her very best to disturb McGonagall's teaching. McGonagall had been a bit hesitant of the idea at first, but had in the end let her lust take the better part of her. Hermione had thought they were both mad, though still demanded Ginny and McGonagall would add their memories to their Pensieve afterwards so that she would be able to masturbate to it later. The Pensieve had first just been between Hermione and Professor McGonagall, but as soon as they told Ginny about it, she had insisted on using it herself as well. That very same night all three of them had spent quite a pleasurable evening going through all the memories so far downloaded into the Pensieve since they had first begun to use it, doing each other as they watched. Hermione and McGonagall had first used the Pensieve only to send masturbation memories to each other during the holidays, but after Hermione had begun her fourth year, they had both agreed it was too entertaining a toy not to use it more often. Ginny's memories now filled quite a large portion of the Pensieve; she had quickly caught up with McGonagall and Hermione since she was easily the most sexually active. Even though she had sex with both Hermione and McGonagall several times a week, she still masturbated at least two times a day, finding new ways to pleasure herself quite as often. She fantasised about Harry mostly, as she thought he was sexy and probably had a big dick. If it was one thing Ginny longed for, it was to get to see his cock. She wanted to suck it, and she wanted him to fuck her. Though she was a bit reluctant about loosing her virginity. She had heard it hurt a lot.

Ginny checked her watch again. It was time. Indeed, the lock of the classroom door clicked, and the door swung open. There was a rush of footsteps from the students getting to their seats, and Ginny held her breath as she heard McGonagall's high-heeled shoes draw nearer. The chair was drawn out, and she glanced out and up. She caught McGonagall's eye, and could see she was sweating. She looked very nervous, but Ginny could tell she was quite horny as well. She leaned back, and let McGonagall sit down. Ginny immediately began to caress Professor McGonagall legs, paying special attention to the inside if her thighs. The students had quieted down now, and by the sound of it were getting their books out.

"Potter! Weasley! Put those away!" McGonagall barked suddenly. "Zonko's items are not allowed in class!"

"Honestly!" Hermione's voice said, apparently annoyed with her friends.

Ginny froze. This was Harry's and Ron's class? And Hermione's? She gave a terrified look up between McGonagall's legs. Had she deliberately chosen this class? McGonagall gave her a guilty smile hidden to the class behind the palm of her hand.

"Hermione insisted,' she mouthed.

Ginny hesitated, but was not going to back down now. She continued caressing Professor McGonagall's splendid thighs, as McGonagall began to speak. Her voice was quite steady.

"Good morning class. Today you are to transfigure the melons before you into grapes, with the procedure described in the homework due for today." Ginny now began kissing McGonagall's legs, very gently at first, but growing more and more hungry, and Ginny smiled inwardly as she noticed the very slight tremble in McGonagall's voice as she said, "You may begin."

Ginny was running her hands ceaselessly back and forth across McGonagall's thighs, and she had now gone from kissing to licking her legs, in long wet motions, leaving trails of saliva where she went. McGonagall rested her chin in her hands, hiding her mouth from view. And with good reason. Ginny had noticed her breathing getting quicker. Ginny lifted McGonagall's feet up, and took off her shoes, then sliding off each of her socks, very gently, and then placed them on the floor next to her. She kissed the upper side of McGonagall's toes, and licked all the way from her ankles to her knees. She reached around McGonagall's ass and kneaded it gently, before sliding her hands past the hem of her cloak and underneath her skirt. McGonagall spread her legs, allowing Ginny to stroke the wet spot on her panties a couple of times before reaching further and beginning to pull them off. She did it very slowly, so as to not make any sounds that would alert the class. She slid the panties over McGonagall's knees, ankles and feet, still very slowly, taking them off and bringing them up to her nose, sniffing them. She cherished the smell of her mentor on them, and rubbed them against her chin for a bit before putting them down on the floor next to McGonagall's shoes and socks, her attention on McGonagall again. Ginny place a hand on each of McGonagall's knees, and gently motioned for her to spread her legs further. As McGonagall parted her legs, her skirt slid further and further up towards her waist, revealing more and more of her thighs and, of course, her naked cunt. McGonagall parted her legs as much as the desk would allow her, giving Ginny plenty of room to manoeuvre her head between them.

McGonagall was incredibly horny. Her gaze was locked on Ron. Your naughty sister is sitting underneath my desk, she thought, just as Ginny began to lick. McGonagall clenched her teeth, breathing as silently as she could through them, eyes still locked on Ron. Hermione was sitting next to him, as usual being the best in class and already having succeeded in the transfiguration. She was carelessly swapping back and forth between melon and grapefruit. She looked at McGonagall, and grinned when Harry and Ron weren't looking. McGonagall tried hard not to smile back. Ginny was letting only the tip of her tongue brush over McGonagall's slit, over and over again, tickling as much as giving pleasure. McGonagall was sweating, finding it very hard to stay silent, feeling a jolt of excitement whenever one of the students would glance at her, as if they knew exactly what was going on.

She slid down her chair for a bit, sitting on the edge of her seat. She was completely open now, naked from the waist down, and Ginny was through with the foreplay. She moved her mouth into position right beneath the entrance of McGonagall's pussy, and then leaned forward and used her whole tongue to lick it very roughly once, before penetrating it, beginning to slowly tonguefuck her.

McGonagall was shaking, and bit one of her fingers to stop herself from screaming. Ginny was now sticking her tongue inside her as far as she could go, moving upwards as she pulled out, licking her insides and bumping over McGonagall's clitoris every time. McGonagall quickly picked up her Transfiguration book, the teacher's edition, which she had on her desk, and hid her face behind it pretending to read it. She clenched her teeth the hardest she could, shutting her eyes even tighter as she came, trembling from head to toes. The area around Ginny's mouth was drenched in McGonagall's juices, and she bent her head forwards and sucked McGonagall's pussy as hard as she could, intending to swallow the next load.

"Are you all right professor?" Ginny heard Harry say, just as McGonagall's body relaxed.

McGonagall lowered the book and tried to look as normal as possible, a very hard task as her face was covered in sweat. Hermione was looking at the ceiling, apparently trying hard not to laugh.

"Yes P-Potter, I'm fine, thank you."

"You look a bit pale -" Ron said.

"I've just got a slight cold, that's all, now proceed with your transfiguration!" McGonagall barked.

Ginny looked up at McGonagall and grinned. Her mentor looked very tired indeed. She gave Ginny a glance before leaning forwards and placing her elbows on her desk, resting her head in her hands. Ginny herself leaned back and rested, as it was a bit tiring to have to sit underneath the desk, not being able to move very much. She longed to caress McGonagall's breasts, but she knew that would definitely be seen, and so she settled for touching her own. She caressed her own breasts, sliding her hands underneath her shirt and resting her head on the back of the teacher's desk. She moved her right hand down from her breast, and then rubbing the damp spot on her pants. She had been getting very horny, very wet indeed when she had licked McGonagall, and she desperately needed release. She slid her hand underneath her jeans and slid a finger inside herself at once. She almost gasped, but caught herself just in time when she remembered where she was. She brought her hand back up and sucked it for a bit, comparing the taste from McGonagall's. Her's tasted sweeter, but in Ginny's opinion it was the same thing as Butterbeer and pumpkin juice; they both tasted great in their own way.

McGonagall had leaned back again, and she seemed to have regained her breath. Ginny leaned forwards again, and looked up at her. She was hiding her mouth to the rest of the class again, and by the look of it, was mouthing for Ginny to keep going. Ginny grinned, and removed her own jeans and panties before sitting up on her toes, spreading her own legs as far apart as she could. She began licking McGonagall again, but this time she was fingering herself at the same time. McGonagall had been numbed a bit after her first orgasm, and was a lot more relaxed this time, purring rather than squirming. Ginny was using her right hand to rub back and forth her own pussy, and her left to penetrate McGonagall's, while teasing her clitoris with her tongue. Ginny wished she had brought a dildo that she could ride as she licked McGonagall. She moved her right hand down to her own pussy to join her left, and placed her mouth on McGonagall's whole pussy, beginning to simultaneously suck and penetrate it with her tongue.

McGonagall had casually slid one of her hands down form the desk and was caressing Ginny's head, massaging her neck. Ginny in turn sped up her treatment, once again making McGonagall lose breath. McGonagall slid her hand down from Ginny's neck and began to play with Ginny's naked breasts.

Suddenly there was a loud explosion, and Ginny stopped sucking McGonagall abruptly.

"There are spare melons over there in that cupboard, Longbottom," McGonagall said.

Ginny relaxed, and began to suck again. McGonagall had on the other hand never stopped caressing Ginny's breasts as she addressed Neville. Ginny inserted two fingers from each of her hands inside of herself and swirled her tongue around the inside of McGonagall's pussy, beginning to rub her mentors clit furiously back and forth her her tongue. McGonagall tensed up at this sudden speed up, and removed her hand from Ginny's breasts and grabbed the edge of her desk, knuckles going white. Her teeth were almost bared, and Harry was looking suspiciously at her. She was just about to push Ginny away from her and give her a sign to slow down when Ginny switched again, fucking McGonagall with her fingers and licking as fast and hard as she could at McGonagall's clitoris. McGonagall came, quickly pretending to drop her quill on the floor and bending down to fetch it. She gritted her teeth and shut her eyes as hard as she could. Ginny took her chance now that McGonagall's upper body was out of sight for the rest of the class and removed her hand from her own pussy, grabbing McGonagall's left breast roughly through her robes once, and then sliding her hand underneath them, ripping away McGonagall's bra. She grabbed McGonagall's other breast, enjoying the feel of her naked flesh in her hand. She pinched McGonagall's nipple quickly before withdrawing her hand, taking McGonagall's bra with her.

McGonagall slowly began to sit up again. That was one incredible orgasm, she thought, and braced herself for the class' looks. She was certain they had noticed her behaviour, and began thinking of excuses. Her head looked over the desk, and she was both surprised and relieved to see that the whole class were still doing their transformations, and not even Harry, who had been giving her strange looks for a while seemed any more suspicious. Hermione gave her an envious look and then proceeded helping Neville with his transfiguration. McGonagall straightened up, and placed the quill back on her desk. She was sweating all over, and felt very naked towards the class now that Ginny had stolen her bra. She glanced down at Ginny. She was hanging her head, and was breathing hard, though not loud enough for the class to hear. She had apparently climaxed too. McGonagall glanced at the class, and then reached one of her hands down to Ginny again. She placed it on Ginny's chin, making her look into her face. McGonagall gave a weary smile, and shut her legs together, signing that was enough for now. Ginny smiled, and settled back against the desk again.

The class was over soon, McGonagall thought. Most of the class had succeeded in making a grapefruit by now, though most were incomplete transfigurations. Potter's grapefruit still had the colour and pattern of a melon, and Weasley's looked more like an orange than a grapefruit. Longbottom's... Looked more like a cross between a turtle and a Quaffle than anything else. It had sprouted three different sized legs, and seemed to be doing it's best to scuttle away from him. Every time Hermione tried to show him how to do it right, the boy seemed to understand less, and even McGonagall had given up on him somewhere along his third year. She looked at Harry again. You could be so brilliant, she thought, if you only tried.

Of course, there hadn't been a year since Potter had begun Hogwarts that he hadn't had more important things to think about than schoolwork. His first year, with Voldemort on his tail, being the only one except for his friends who'd believe that the Philosophers stone was anything else than perfectly safe. Second year, suspected of being the heir of Slytherin, not daring to tell the teachers of the basilisk voice he heard for fear of being thought of as mad. Third year, his no good godfather after him and Dementors trying to suck out his soul. And this year, unwillingly made Hogwarts champion in the Triwizard Tournament. Poor boy... He couldn't seem to get a brake, could he? She looked over at Hermione. She was still desperately trying to teach Neville how to move his wand.

"No, no, no Neville, use your wrist when you make the wand flick, not your fing - "

KABOOOM!

"Never mind fetching another melon, Longbottom." McGonagall sighed. "The lesson will be over soon."

No sooner had she said that than the bell rang and the class began to gather up their things. Good timing too, McGonagall thought, as Ginny was had begun to caress her thighs again. She gave Hermione a glance, and she nodded back slightly.

"You go on ahead to lunch, I've got some things I want to ask Professor McGonagall about, " Hermione said to Harry and Ron, who gave her a wave before exiting out through the door with the rest of the class.

Hermione waved back and waited until the last of her classmates had left the classroom before closing the door. McGonagall backed away from the desk and Ginny crawled out. She settled against the side of it and Hermione could see her buttcheeks glisten with sweat.

"Ok, I'm soaking over here, when's your next class?" Hermione asked. Ginny, who had begun to masturbate where she was sitting, looked up at McGonagall, who was smiling.

"Would you lock the door please miss Granger?"
