Felix Sinclair was dealing with a tricky predicament. He was invisible and stiff as a board, stuck in the back of a chorus recital room, secretly watching the Hufflepuff Honeybees practice for the upcoming chorus competition. With a faulty Freezing Charm holding Felix in place, he was unable to do anything but wait for it to wear off, and hope he wasn't discovered. He had managed to hide in a pile of seat cushions, but he had no idea how much time that would buy him.

The Honeybees were singing a circle in the center of the room, their voices resonating off the walls. Felix couldn't help but admit that they were talented, despite them being Ravenclaw's main competition. He listened in quiet admiration as they continued vocal warm-ups, their voices rising and falling in perfect harmony.

With a clap of her hands, Bridget Murphy silenced the singing. Felix's eyes narrowed as he watched the blonde section leader reach into her robes and withdraw four necklaces. Agnes Abernathy squealed as the items were produced, and was promptly hushed by the others.

"What are those?" Felix thought to himself, his curiosity piqued. The girls voices dropped to hushed tones. He strained to pick up the words.

"I figured we could use some extra help for the competition," Bridget whispered, handing out the necklaces to the other girls.

Fiona Finnegan took hers hesitantly. "Are you sure about this?" The youngest of the group, her blue eyes expressed concern.

"Don't be a knob, Fiona," one of the other girls, Maeve O'Sullivan spoke up as she put hers on. "We can't afford to lose." Fiona stuck out her tongue at Maeve but put the necklace on as well.

As he watched, Felix noticed something strange happening as each girl clasped the necklace around her neck. Their posture changed, spines straightening and chests puffing out as if they were suddenly more confident. Felix realized that the necklaces were improving the wearer's physical presence and charisma.

Felix's eyes widened as he recognized the spell. The girls were using necklaces with Enhancement Charms!

He felt vindicated now that he had caught them red-handed. However, his excitement soured as he remembered that he couldn't confront them due to the Freezing Charm. He struggled against its hold as the girls continued to practice, growing frustrated as he made no progress. Oblivious to Felix, the Honeybees continued their practicing with renewed vigor, the enhanced necklaces strengthening their voices tremendously.

As they sang, he felt himself being moved by the music, caught up in the melody and harmony. It was as if the music was pulsing through him, making his body vibrate with each note. He caught himself, realizing that the Enhancement Charm was making the music affect him. Despite knowing their voices were magically altered, he was quietly impressed with their singing. Assisted by the magical items, each girl's voice became stronger, able to sustain notes for minutes at a time.

Finally, the girls paused after singing for an hour straight. Having dozed off to the melodic sounds, Felix's eye snapped open in the silence. He willed his limbs to move, hoping the Freezing Charm had weakened, to no avail. He was still trapped.

Fiona sighed and rubbed her neck. "I can't believe we're still up this late," she complained. Agnes nodded in agreement, stifling a yawn.

Bridget turned to them with a glint in her eyes. "We can't give up now. We've been practicing for weeks, and the competition is only a few days away," she said, her voice filled with determination. "Let's take fifteen and then get back to it."

With Bridget's words of encouragement in their ears, the girls took a quick break. Felix watched nervously as they began to walk around the room. He wished he could move and escape, but he remained rooted to the spot.

Felix's pulse jumped as Fiona stood up and started walking in his direction. She was a beautiful girl with pale skin and red hair that cascaded down her back in loose waves. She was wearing a pink shirt and a pair of tight-fitting jeans under her school robes. As she approached Felix's hiding place, he could smell her perfume, and he felt a sharp pang of guilt knowing he would ruin their reputation with what he knew.

Fiona sat down on a pile of seat cushions next to Felix, stowing her charmed necklace in her pocket. She yawned and stretched out for a nap, unknowingly laying right beside Felix's invisible body. He could feel her warmth, and admired the cute redhead as she got comfortable beside him. Within a few minutes she was fast asleep, completely unaware of the invisible boy beside her. Felix realized that this was the closest he had ever been to a woman in his life, and he couldn't help but marvel at the exhilaration of being in such close proximity.

As Fiona slept, she rolled over to face Felix, her body almost brushing against his. She murmured something in her sleep and shifted her body even closer, draping an arm over him. The sweet, flowery scent of her perfume made his heart race, but he also felt terrified that she would wake up and see him. He lay there in beautiful terror, staring at her sleeping face close to his as he awaited being spotted.

Humming softly to herself as she walked by, Maeve O'Sullivan paused as she saw Fiona. Felix's heart leapt as he saw her eyes narrow, noticing Fiona's hand hovering in the air. Maeve screamed in shock, and Fiona jumped up startled. Felix's heart began to race in fear.

Maeve's expression was one of fright. "Fiona, what's happening? Your hand..." she stammered, pointing at where Fiona's arm was previously hovering.

Fiona looked at the empty space next to her and rolled her eyes. "Don't prank me like that, Maeve!" she pouted. Inches away, Felix's eyes darted nervously between them.

Maeve shook her head, her voice rising in pitch. "I'm not, I swear! There's something there!"

Fiona frowned. "Okay, Maeve, I get it. I shouldn't be sleeping during practice. But you don't have to scare me!" She then patted the area next to her, trying to prove a point. However, her hand landed on Felix's abdomen, trailing lightly down his stomach before brushing against his invisible privates, and she screamed in shock, jumping up.

"What the-?!" Fiona exclaimed, her blue eyes wide in fear as she looked around frantically. The other two girls quickly came running, their faces filled with worry.

Fiona's unexpected touch, coupled with the excitement of being caught inflamed Felix. He couldn't believe that he was becoming erect at a time like this. Fiona's hand had only brushed against him for a second, but Felix felt his manhood spring to life as if electrified.

Agnes Abernathy rushed over, her eyes wide with concern. She knelt down and cautiously touched at the air until she also encountered Felix's invisible erection, hesitantly taking it into her hands in an attempt to understand what it was. "It might be a Boggart!" Agnes exclaimed, her voice trembling with fear. Her shaking hands remained loosely clasped around Felix, and he felt himself growing harder at all the sudden attention upon his lower half.

Bridget was skeptical. "No, no, no," she disagreed, shaking her head. "A Boggart isn't invisible. It just takes the shape of your worst fear."

Maeve got down next to Agnes and grabbed the invisible object from her. Felix's breathing increased as the dark-haired girl's fingers encircled his shaft, squeezing in a much tighter grip. Maeve massaged Felix's flesh thoughtfully as she figured out what it was. Being the most "experienced" of the four girls, it didn't take her long to piece things together. She froze in shock and jumped up.

"It's a boy!" she screamed. The other girls gasped in shock and stepped back.

Cold fear began to creep up on Felix as he pondered his situation. He expected the girls to use all sorts of nasty curses and hexes on him once they pieced together he was spying.

Amazingly, Bridget was still skeptical. "But why is he invisible?" she asked. She stomped over and decisively grabbed Felix's privates. "And why is this the only part that's moving?"

A brief silence ensued as the girls huddled together, whispering and throwing confused looks at the invisible object in Bridget's hand. Felix's senses were on high alert as he watched his captors frown at him thoughtfully, but a small part of him was intensely focused on the warm feeling of Bridget's hand holding his erection tightly.

Completely unaware of her effect on him, Bridget absentmindedly toyed with the object in her hands, running her fingers up and down his sides as she gauged its length. The blonde Irish girl's face looked bold and determined as she focused intently on the spongy flesh in her hands. The sensation radiated through Felix, and he squirmed, starting in shock as he realized his body moved slightly. The Freezing Spell was starting to wear off!

With desperation, Felix began to struggle against the waning spell. Still fairly effective, the weakened spell kept his legs and arms pinned, but Felix was able to move his hips slightly. Bridget jumped as she felt the invisible object move for the first time. She doubled her grip on it, taking Felix's rod in both hands. With little pressure, she was able to easily hold Felix in place, resisting his efforts easily as he thrusted against her.

"He's starting to wake up!" she warned. Felix's heart raced as he tried to think of a way to escape. With a renewed burst of strength, he attempted to break free from Bridget's grip but it was no use, the golden-haired girl had her hands wrapped snugly around the base of his shaft, pressing firmly downwards. The struggle was one-sided, Felix's hips feebly raising off the floor as Bridget squeezed her hands together around his cock, pressing him back to the floor. She continuously adjusted her grip, shifting her hands to maintain her grip as the invisible mass below her squirmed. Felix found the conflict exhilarating, watching the determined look on Bridget's face as she fumbled blindly to keep his member secured in her tight hands. Capturing Felix's stiff rod once again in a vice-like grip, she forced him back to the floor as she looked to the other girls for help.

"We should report this to the Headmaster," Agnes said, her voice rising with fear.

"We should let him go," Fiona said, biting her lip nervously.

"We should beat him up for watching us!" Bridget said, tightening her grip on Felix. An involuntary gasp escaped him as the blonde section leader squeezed even tighter. He continued to struggle frantically, hoping he could weaken the spell faster with his efforts.

Thinking he was attempting to escape, Bridget swung a leg over his torso, straddling Felix and using her entire weight to keep him held to the ground. Her school robes flowed out and behind her, covering Felix's entire head in darkness as she sat on him. Felix felt the weight of her body bounce against his chest, knocking the breath out of him. He gasped for air, chest straining beneath Bridget's weight as she settled into position on top of him. Her jean shorts rubbed uncomfortably against his chin and he struggled to move his head, but even the weakening Freezing Charm was still strong enough to hold him.

Bridget used the leverage from her new position to press down on Felix with her behind, leaning backwards so that the majority of her weight sat upon Felix's chest. By breathing shallowly through his nose Felix was able to survive, but the air underneath Bridget's robes was quickly filled with the smell of her. The strong feminine scent emanating from her shorts invaded his nose, and he found it difficult to focus on escaping while inhaling mouthful after mouthful of Bridget's aroma. Her hands continued their forceful movements on his cock, and Felix found himself secretly enjoying the feeling of thrusting against Bridget's hands as she struggled to restrain his erection.

"Ideas, girls!" Bridget exclaimed, sweat glistening on her forehead. She couldn't tell whether it was her sweaty palms or not, but the invisible member was becoming slippery in her hands, making it tough to hold her intruder down.

Through Bridget's thick school robes obscuring his face, Felix could hear muffled conversations coming from the other Hufflepuff girls. After a while, Maeve's voice cut through clearly.

"We should interrogate it and figure out what it knows," she declared.

The other girls looked at each other. Felix paused too, laying still in Bridget's grip as he heard the words. Bridget sensed the pause and caught Felix by surprise, squeezing his cock tightly with her small hands and forcing him back down to the floor.

"But what if it's dangerous?" Agnes asked nervously, eying Bridget's crouched position on top of Felix.

Fiona agreed, her red curls bouncing as she nodded. "We don't even know what it is. It could fight back."

Maeve stood her ground. "Well, we won't know anything unless we do something. We need to figure out what it is and what it's doing here."

Felix felt a cold bolt of fear hit him as he heard no further objections to Maeve's suggestion. He didn't know what they were going to do to him, but he knew he didn't want to find out. He lay in the darkness underneath Bridget's robes, hoping that he could get free of the spell and escape before things got worse.
