Luna awoke from her disturbed slumber as she usually did: just as the sun was coming up. Thinking absolutely nothing of the dream she'd been having about Harry, she got dressed - barely registering the sticky residue that had been present on her underwear for the last few months. Creeping past the other girls, she headed for the staircase and descended to the common room.
Planting herself on the sofa and opening a book, she relaxed and found her thoughts unable to focus on the book; instead wandering away - to Harry. For the first time, she consciously imagined him fully nude, lying on a bed - his huge member twitching with lust. A surprise to herself: she had never imagined anyone naked! This was most unlike her - she was the quiet, quirky nerd that no one ever saw or spoke to. She wasn't a sexual person, was she? Blushing, she glanced around the empty common room, feeling a warmth growing… down there! She'd felt like this a couple of times before, but she had felt embarrassed about her urges and ignored her body. This time was different though; it was much more intense than before and she needed to do something about it - though she wasn't sure what. Pulling her skirt up, she felt a along her womanhood, sighing as the soft cotton of her panties rubbed gently against her. Her arousal grew, and she felt a wetness forming - causing the tips of her fingers to dampen. Feeling even more risqué than she even thought possible, she gently slipped a finger down the front of her underwear and moved her fingers along her skin, slowly discovering her anatomy as she felt the sensations of her labia being carefully teased apart and caressed. She was eager to find her clitoris - she'd heard some of the older boys talking about it, but had never gone looking. Still sitting up, and after a couple of minutes of exploring, her now drenched fingers happened to rub across a small, hard nub of flesh that sent a rush of pleasure so intense she reacted by quietly gasping and clamping her legs shut. Sure that this was it, she spread her legs wide and placed a finger on it deliberately - and felt an unexpectedly intense spike of joy emanating from her newly-discovered clitoris. Gasping for breath, trying not to make a sound, she felt a small trickle of fluid escape from… somewhere down there.
Desperate to continue, she began tenderly rubbing back and forth, sending wave after wave of uncontrollable nerve impulses into her very core, involuntarily twitching her hips with each stroke. Fully red in the face, Luna entered a trance, imagining it was Harry's finger doing this to her. Feeling more mystery fluid flowing out of her, she suddenly went tense and felt her breathing and heart rate go bonkers, trying to keep up with her pussy, which seemed to be twitching all on its own. Letting out increasingly strained gasps - she eventually lost herself in a tsunami of pleasure. Screwing her eyes tight shut, she rocked back and forth, addicted to the feeling of her finger touching her clit. After a few more seconds, her first ever orgasm subsided and she was forced to stop rubbing herself as it became uncomfortable. Removing her hand from her pants, she laid back into the sofa as she regained her breath, glowing with satisfaction.
