Hermione breathed out to try calm herself, for the last few weeks she had dreaded going to her Magical Legislation classes, the structure was unlike other lessons, these were held in the Library, and once Professor Grey had given his lecture, the last thirty to forty-five minutes was spent reading through tomes of old legislation and laws upon which to write your paper on.

That when it had started to begin, Hermione had been trying to get a particularly large tome down from a high shelf when he had fallen from the ladder, but rather than falling to the floor and hurting herself, someone had caught her, looking up she found Professor Greys' eyes staring back, deep into her, she had never noticed before but they were grey also, but not a cold or dull grey, these seemed to have a heat behind them, coming back to herself she realised he had been holding her and staring at each other for nearly a whole minute, and Professor Grey had one hand, holding one of her buttocks firmly in his hand, underneath the skirt, she jumped out of his eyes, blushing all over and quickly said, "Thank you sir, erm I think I'll go back to my dormitory now, I don't need the library any more today".

Then she had scurried off to her dormitory, the whole way she could feel is strong hand on her ass and those fiery grey eyes burning into her.

By the time she crawled back through the portrait of the Fat Lady she was feeling less embarrassed about the situation, he didn't realise he was holding her butt, he was just holding her for so long because he wanted to make sure she was over the shock of falling before putting her down. But she had to admit the whole scenario had got her more than a little wet, so she rushed off up to the girl dormitory, she poked he head in the door checking it was clear then went in and stripped down to her underwear as she did so.

She loved being in her underwear, just walking around in nothing but this made her feel so sexy, these were her favourites a little red lace set with a thong and bustier that made her breasts look huge and round, they made her feel a little slutty, like some nymphomaniac that would fuck anything or anyone, but she new really she only wore them for herself.

She laid on her bed and started touching herself softly, one had rubbing her breasts through her bra, making her nipples start to go hard while the other stroked down her chest over her mound lightly brushing her pussy through the lace which she could feel where already wet, past her wetness and down to her thighs, she loved massaging her thighs, she had perfectly toned thigh which led to a lovely round ass which had received more than a few compliments in its time

she carried on this way for some time, getting her nipples hard so she could tweak and pull them through the bra making her gasp, massaging her thighs and brushing her hand lightly over her stomach and mound, she could feel herself losing control, getting to the point where being aroused takes over all reason, she reached into her top drawer and pulled out a rubber dildo, one of the few muggle items that she brought to school with her, along with a couple of other choice toys, this one was about eight inches long and fairly wide, and average sized penis, it had said on the box. She first put it in her mouth enjoying its silky texture and the feeling of its weight on her tongue then she led it down her body, over her breasts and towards her pussy, her wetness had soaked through the lace now and was clearly visible on them, knowing how she would look if anyone walked in made her feel so naughty and this always helped her along, she rubbed the dildo over her pussy through her thong to begin with loving the tease of the slight brush against her clit and over her sensitive lips.

She pulled the lace to one side and tease her pussy further, rubbing the tip of the dildo over her clit and down to her opening, she was moaning now and gasping when the tip touched her engorged clit. She pushed the cock deep into her getting all eight inches in and holding it there, then pulling it out she began to fuck herself, sliding the dildo into her pussy she pushed it all the way in and broght it nearly all the way back out again before pushing it back in again, she was getting close now but she wanted more, she knelt up on the bed, riding the dildo now letting it get deep, then she pulled out her wand, pointed it at the dildo and whispered, "engorgio", the dildo got bigger inside her, stretching her pussy and making her cry out, this was so good she could feel it filling her up, ending the spell before the dildo got too large she grabbed the now twelve inch dildo and getting onto all fours she fucked herself hard, she was getting really close now, she could feel the edge of her orgasm closing it, she stopped quickly and tore her bra off letting her breasts fall out, she grabbed a nipple in her spare had and started to twist and play with it, then like a wave crashing down she came, her juices flooding out of her pouring down her legs forcing past the engorged dildo to soil her bed sheets.

Flopping down onto the bed she was breathing heavily, it had been a while since she had orgasmed so hard, she pulled the dildo from herself and casting a spell "reducio" she shrank it back down to its normal size, next he stepped back from the bed looking at the mess she had made, he bra tossed on the bed which was now spotted with patches of her orgasm, she waved her wand and said "scurgify" and blinking the filth was gone and her bra was nicely folded on the bed, she collected this and her other clothes and re-dressed, depositing her toy back in her drawer and locking it with "colloportus", she left the dormitory and headed to her next lesson, feeling a lot more clear headed.
