She tries but it harder than thought

Hermione dropped back onto her bed, fondling her tits and moaning. Pleasure was filling her mind and she felt that it was sweeping away more thoughts as she kept going. Finally, she had a powerful orgasm, laying there with her legs spread and panting slowly. Then she realized with slight panic that she was way too late already for her class and jumped up. She soon realized that most of her clothes were not fitting her body anymore but lucky, she could grab a bigger shirt from Lavender's wardrobe, realizing that she was way more busty than Hermuone had been.

The corridors were mostly empty, with most students in classes. Hermione somehow managed to sneak into the spellcraft class, sitting next to Ron. Professor Flitwick seemed not to care that she was late, probably not worried about Hermione's progress in his class.

Hermione herself was rather worried although. She was quickly realizing that she was struggling to follow the class. her head was filled with sexual thoughts and it seemed all the instructions the prfessor were giving were just immediately gone.

"You alright?" Ron asked as Hermione almost made Parvati's skirt catch fire when she messed up a spell.

"I ... yes," Hermione said as she noticed him staring a bit at her chest The attention made her horny and she feared if it would keep going, she would just bend over and suck him off. Glady the class ended and before someone could ask more questions, Hermione hurried out, trying to find Luna.

As she hadn't any luck, she finally came to the library and realized that maybe she could find a spell which reversed her state. It took an effort to sneak into the restricted section but finally, she managed it, almost tossing over a pile of books with her enhanced tits.

"Where is it?" she wondered and looked through some books for a Counterspell, realizing that she was struggling to understand all the instructions.
