The Beginning
Hermione eased her way into the classroom, a book clutched tightly in her hands. She’d found it in grimmauld place over the summer while visiting harry.
Alone briefly in the library, she’d picked the book up randomly, only realising what it was about when she saw the illustrations. At first, the images inside had shocked her, but her surprise quickly gave way to arousal. Awakening a need she’d never fully acknowledged.
She spent the rest of her summer reading the book and coming to terms with its contents and now she was at Hogwarts she could try it out.
There were hundreds of spells, each one more elaborate than the last. For now, she planned to use one of the simpler spells as a test.
First, of course, she needed to clean the room. She wasn’t as good as some of the teachers, but a bit of work with a levitation spell and a couple of cleaning charms soon had all the old desks moved back to give her some space and the floor cleaned.
Kicking off her shoes, she sat on the floor, her legs tucked beneath her. Hermione couldn’t help but picture her classmates sitting at the desks, watching everything she was about to do. The thought made her breath catch, her nipples hardening in arousal.
Giggling quietly to herself, she pushed the thought away for later and removed her jumper and tie, leaving her in just her blouse, skirt and tights. opening the book to her chosen spell and readied her wand.
She briefly considered taking her top off, but quickly decided it would be more fun with it on.
Focusing on what she wanted, she cast the spell. Her wand lit with a soft green glow and a pleasant warmth spread across her chest.
The heat built up in nipples, which were so hard it hurt and clearly visible through her blouse. Then her bra started to feel tight, the fabric pressing against her flesh.
Biting her lip to silence a moan, she looked down at her breasts. As she watched, they started to push forward, their outline becoming more defined as they grew.
As they grew, she squeezed her thighs together, trying to ignore the growing wetness as she needed to concentrate on the spell.
"Oh ... oh, it feels ... good!" she moaned. They continued to swell in small bursts. Her blouse slowly started to fill, the fabric pulling taut across her breasts.
Her bra straps were digging into her back, she could clearly see the outline of her breasts overflowing the cups. "I'm the same size as Susan!" she thought. As her blouse began to un-tuck itself from the front of her skirt.
Large gaps were visible between the buttons and her something was starting to creak. She squirmed as the delicious, pulling heaviness increased. With a quiet rip, the fabric joining the cups of bra gave way, her breasts surging forward into the blouse, threatening to pop the buttons from her blouse.
She couldn't resist the feeling anymore and she cupped a breast with her free and began squeezing and rolling it beneath her top. Her breathing was heavy as she felt her flesh push against her palm.
They're so full and heavy. The feel of the warm cotton material rubbing against her swollen nipples excited her even more, and she arched her back in sexual ecstasy. Katie and Anna couldn't believe what they were seeing.
It was getting hard to breath and She grunted as another growth spurt hit. Throwing her shoulders back she pushed her chest forward.
Come, on!
With loud snap, the middle two buttons tore away, shooting across the room. The sound alone was almost enough to push her over the edge and she crushed her thighs together in an effort to focus on the spell.
Screwing her eyes shut, Hermione knew it was no use, nothing was going to stop what was coming. She could feel it building, her sex throbbing with every growth-thud, thud, thud-
Orgasm hit her like a punch, she shuddered and moaned softly. Her eyes flew open as the last of the buttons gave way and her grip on the spell failed.
Panting, she tried to gather her thoughts.
“Okay,” she muttered, her voice thick with arousal, “I
might have overdone it.”
Shrugging her shoulders, she let the ruined remains of her shirt fall away, watching as the movement caused her breasts to jiggle.
They weren’t just big, they were huge, massive even. Yet despite that, they remained firm and perky, capped by her pink nipples. It was probably only because of the magic that she could still move despite the weight. Biting her lip, Hermione ran a hand over their surface, gasping at the sensation.
Then again, the spell wasn’t permanent so why shouldn’t she enjoy herself? She ran a hand over her breast again
There was a quiet knock at door. “Hermione, you in here?”
“Yes, you can come in Harry!” As door opened, she smirked at his startled gasp. “Close the door Harry … and make sure you lock it.”
Maybe she should see what else that spell could work on.
