In the underground training chamber of Blackfeather Manor, the walls were built of massive, cold, and hard obsidian, designed to absorb the majority of uncontrolled magical impacts. Jerry stood casually at one end of the training field, while Katherine stood twenty meters away on the opposite side.
She was still wearing the ink-black catsuit. In a situation requiring extensive movement, the constricting feel and the sound of friction generated by the suit were amplified several times over. She held her wand, looking at Jerry with a complex expression.
"Attack me with your strongest spell," Jerry's voice echoed in the empty training chamber. "Let me see the caliber of a Slytherin senior."
Katherine took a deep breath and raised her wand. As she lifted her arm, the tight catsuit contoured her upper body relentlessly. Her full breasts were tightly compressed and pushed up by the garment, creating a breathtaking curve that subtly trembled with her breathing.
"Stupefy!" she cried sharply, flicking her wrist. A red beam of light shot from her wand tip, heading straight for Jerry. To put more power into the strike, her body instinctively leaned forward, twisting her waist. This motion caused her perky bottom to protrude backward. The two generous, round cheeks, tightly encased in the rubber, strained into an inviting curve, even oscillating slightly from the force of the movement.
Jerry didn't even raise his wand. With a casual wave of his hand, an invisible barrier formed in front of him. The red light struck the shield and silently dissipated.
Her first attack failed, and a faint blush crept onto Katherine's cheeks. Disbelieving, she waved her wand again, this time quicker and with a greater range of motion. She stepped forward, lowered her stance, and thrust her wand upward from a tricky angle.
"Impedimenta!"
As she uttered the spell, her body was practically pulled into a fully drawn bow. Her breasts, pushed forward by the lean and the swing of her arm, were squeezed and jostled within the catsuit. Meanwhile, her protruding buttocks, constrained by the tight garment, were utterly revealed in their rounded, perky shape. Light reflecting off the slick rubber gave them an oily sheen, making the two soft cheeks, constantly shifting with her movements, even more captivating.
Jerry chuckled, watching Katherine's futile attacks. He casually cast a Shield Charm on himself. A milky white aura instantly enveloped him, like a form-fitting, flowing suit of armor, the glow subtly pulsing with his breath.
"I'll give you a chance," Jerry's voice was exceptionally clear in the training chamber. "If you can break this charm, you won't have to wear this suit until school starts. If you can't break it..." He didn't finish, but the playful look in his eyes said it all. "Then get ready to wear the gag until school starts."
This wager made Katherine's breathing catch in her throat. Temporary freedom or deeper humiliation—it all depended on her next performance. She had no choice.
"Impedimenta!" She shouted the spell again, but this time, her movements held a desperate resolve. To gather strength, Katherine lowered her body even more, her right leg pushing backward. This posture lifted her bottom high, the tight rubber suit constricting the two soft, generous cheeks even tighter, the crease between them almost invisible. As the spell was released, she twisted her waist hard, sending her entire bottom swinging in a highly sensual arc, the rubber friction emitting a "creaking" sound, as if in agony.
The red light hit Jerry's Shield Charm, merely causing a ripple before vanishing.
"Is that all the power you have?" Jerry's voice held a trace of mockery.
Katherine's face was flushed crimson. She quickly waved her wand again, a rapid succession of spells tumbling from her mouth.
"Stupefy! Petrificus Totalus!"
Katherine's movements became faster and more frantic. Every swing of her arm caused the two full, soft masses on her chest to violently jiggle under the pressure of the rubber suit. Their shape was squeezed, twisted, then quickly rebounded. The impressive volume was palpable even through the rubber. Katherine constantly changed her footwork and posture, sometimes sideways, sometimes forward-arched. With every exertion of force, her encased buttocks tightened behind her, the rounded silhouette reflecting the light from the obsidian walls, looking slick as if coated in oil.
Soon, a thin layer of sweat seeped from her skin, making the catsuit cling tighter and slicker to her body. Katherine could feel the rubber on her inner thighs rubbing with a sticky, shameful creak with every movement.
Katherine's breathing grew frantic, her chest heaving faster and faster. Yet, no matter how hard she tried, the spells were like stones sinking into the sea, unable to shake the thin aura surrounding Jerry in the slightest.
"Put some power into it. Think about when you cast Avada Kedavra before."
"I don't keep dead weight around."
The depletion of magic and the futility of the attacks made Katherine's body increasingly hot. Sweat practically saturated the inner layer of the catsuit, making every movement accompanied by a sticky, slick friction.
"Expelliarmus!" Katherine shrieked. It was no longer a standard dueling spell but carried a desperate, ruthless intent. She abandoned the long-range confrontation and lunged at Jerry like a female leopard. Her idea was simple: if she could close the distance and disrupt his rhythm with a physical charge, she might find a slight opportunity.
As she rushed forward, her notably full, youthful breasts, tightly encased in the rubber, bounced and shook wildly across her chest due to the vigorous running, creating dizzying waves of flesh.
However, Jerry simply slid aside a step just as she reached him. Katherine's charge missed, and her body stumbled forward due to the immense momentum. The instant she passed him, a hand, with an irresistible force, accurately slapped her firm, round bottom.
"SMACK!"
A sharp, clear sound echoed in the empty training chamber. The palm didn't just bring sound; it brought a kneading. Through the layer of slick rubber, Jerry's fingers sank into her full buttock, grabbing a handful roughly. The surprising elasticity and softness made Katherine's body instantly twitch as if electrocuted. Her legs went weak, and she nearly collapsed to her knees.
A wave of humiliation surged to her head. She spun around abruptly, her wand pointing at Jerry, the tip glowing red.
But Jerry was faster. He stepped forward, instantly closing the distance. Katherine's vision blurred. The hand that had just violated her bottom had already reached for her chest.
"Ugh!" A muffled groan escaped her.
Jerry's small hand covered her left breast without ceremony. His fingers splayed, gripping and kneading hard. The substantial soft flesh was squeezed out of shape in his palm, some of it spilling out between his fingers. Through the thin layer of rubber, he could distinctly feel the astounding weight and softness.
Katherine's offensive spell choked in her throat, her body stiffening from the sudden violation. Jerry, however, seemed to have found an amusing toy. His other hand also covered her right breast. Both hands worked simultaneously, roughly handling the two large masses of soft flesh on her chest like spoils of war.
Jerry seemed to tire of the game. He let go, took a step back, and looked at the "maid" before him, who was subtly trembling with shame and panting. He casually waved his hand.
"Levicorpus." He didn't even use the standard incantation. An almost invisible magical pulse struck Katherine. Her body instantly lost all weight and drifted uncontrollably upward, her limbs flailing helplessly in the air, like a puppet on strings. The tight catsuit stretched her body's curves to the maximum due to gravity's pull.
Jerry gave a slight flick of his wrist. Katherine's body shot horizontally like a stone launched from a catapult, slamming heavily onto the ground at the other end of the training chamber.
"BANG!"
A dull, loud thud of flesh colliding with the stone floor. Katherine landed on her side first, then tumbled and slid seven or eight meters across the slick obsidian floor. During this, the two large burdens on Katherine's chest were the most obvious victims. With every roll and impact, they smacked heavily against the floor, compressed into flat shapes, then violently rebounded due to their immense elasticity, jiggling frantically within the rubber suit. Her bottom suffered the same treatment. Every collision with the ground caused the two round cheeks of soft flesh to violently undulate and slap.
Finally, Katherine lay face down, sprawled on the ground in a humiliating posture, her limbs spread out, her body twitching uncontrollably from the intense pain and the impact. The black rubber was covered in dust, tightly clinging to her heaving body, painting a picture of total defeat.
Jerry slowly walked over to Katherine. The sound of his leather shoes on the obsidian floor was exceptionally clear in the empty training chamber. He stopped by her head, looking down at the woman lying prone, her body curves utterly exposed.
From Katherine's angle, looking up, she could only see Jerry's slender calves. Further up was his face, still bearing a touch of youthful innocence, arguably even pretty. Yet, this thin, eleven-year-old body exerted a mountain-like pressure on her. The sheer contradiction gave her a dizzy, absurd feeling.
Jerry shook his head and let out a faint sigh. The sound was clear, not yet fully stripped of its childlike pitch, but the words he spoke were ice-cold.
"I'm starting to doubt the quality of Hogwarts' education." He looked down at Katherine, as if inspecting a flawed tool. "If a seventh-year student like you is considered one of Hogwarts' best, it's hard to imagine what you'll use to resist when Voldemort returns."
He lightly nudged Katherine's waist with the tip of his shoe. The touch made her body flinch. "Casting spells by shouting the incantation beforehand—anyone who didn't know better would think you were putting on a ridiculous magical performance on a stage." His tone was full of mockery. "You lost. Starting today, wear the gag outside of mealtimes and carefully reflect on what mistakes you made in the recent combat."
Hearing the word "gag," Katherine's body subtly twitched, a stifled whimper escaping her throat. Jerry seemed not to notice her reaction, continuing in his flat, childlike voice to utter words that chilled her to the bone.
"Tomorrow, if you still can't break this Shield Charm, which is frailer than a potato chip!" He squatted down, leaning close to her ear, his warm breath fanning her earlobe. "I will place a small, cute little gift... inside your ass."
That threat, delivered in a boy's clear voice, was like an ice pick stabbing Katherine's nerve endings. She lay motionless on the ground, yet her body showed a subtle reaction to the lightly spoken words. After a while, she managed to raise her head, looking up at the slender boy squatting before her. Fear, humiliation, and a massive, incomprehensible confusion intertwined, making her ask a question in a shaky, hoarse voice:
"Are you really only... eleven years old?"
It was understandable why she would ask. The image from the bathroom still echoed in her mind: the massive presence, vaguely visible in the warm steam, almost as thick as a grown man's arm. That unnatural grandeur, contrasted with the childish face before her, created the most bizarre juxtaposition. Coupled with the magical strength he had just displayed, easily crushing a seventh-year student like her... all of it made her question whether the being before her was truly just a boy.
Hearing her question, Jerry grinned. It was a pure, unadulterated smile on his handsome face, yet it made Katherine's heart pound. Jerry didn't answer but stood up, offering his response through action.
The moment he unzipped his pants, the monstrous object, confined for too long by the tight trousers, eagerly broke free. It didn't slide out slowly; it sprung forward violently, with an almost lifelike force. Katherine didn't even have time to react, only feeling a warm, heavy weight against the side of her cheek.
The enormous shaft had slapped directly against her face. The tip of the head brushed past her nose, and the shaft rested firmly against her cheek. A rush of warm, vibrantly alive flesh, mixed with the faint scent of skin and hormones unique to a boy, instantly enveloped her. This was completely unlike the cold, stiff silicone feel of the previous gag. This was alive, warm, and subtly throbbing right next to her cheek.
She froze completely, forgetting even to breathe. Her vision was consumed by the massive shaft, which blocked out half her sight. She could clearly see the raised blue veins on it, and feel the texture of the skin—delicate yet resilient. The absurd idea was now terrifyingly real.
This was not a mold from the gag inside the mask. The object on the gag was a cold, lifeless replica. The object now pressing against her face was the terrifyingly powerful, living original. The warm, resilient sensation pressed tightly against Katherine's cheek. The subtle throbbing constantly reminded her that this was a living thing belonging to a young boy.
Her reason screamed in denial, trying to attribute it all to some advanced Transfiguration or a cruel magical prank. But the sensory impact was so direct, so undeniable.
In the midst of the chaos, a nearly instinctive action to confirm the reality occurred. Katherine's tongue, without her control, slipped out between her lips. With a barely noticeable hesitation, she tentatively licked the coarse shaft. Her moist tongue surface met the warm skin. A faint salty, musky taste, mixed with the unique scent of a young male, instantly spread across her taste buds.
This taste and touch shattered the last sliver of hope in her heart. This was not an illusion. This was real.
And the instant she completed this confirming action, Katherine distinctly felt Jerry's body tense uncontrollably. A heavily suppressed moan, straddling the line between boy and man, escaped from deep in his throat.
Katherine was stunned. She had only licked it. Before she had even begun to act, his reaction was this intense?
A wild, daring thought flashed through her confused mind like lightning. Katherine tried again, her tongue clumsily scraping the surface.
"Mm!" This time, Jerry's reaction was even more obvious. His slender body violently shuddered. His hands instinctively clenched into fists, as if struggling to restrain something. The enormous object pressing against her face also began to throb with greater intensity.
Katherine had finally found it! This seemingly omnipotent, unfathomable boy, this figure like a demon lord, possessed a body with a deadly sensitivity appropriate for his age! He simply couldn't control such intense stimulation!
She'd found it! She'd found his weakness!
Jerry could feel the hot, wet touch on his body and saw Katherine's eyes, now completely unfocused because they had confirmed the truth. As if to conceal something, he moved his hips again, letting the colossal object gently rub against her tender cheek, before slowly straightening up.
"Now," he asked softly in his still-clear boy's voice, close to her ear, "do you still think I'm a child, Scholastica? Even though I truly am only eleven."
A smile slowly bloomed on Katherine's face. It was a faint smile, carrying the clear understanding of someone who had seen through everything.
"Yes!" Katherine spoke, her voice hoarse and low, yet tinged with an unprecedented emotion. She smiled and said, "I'm sure of it, my Little Master!"
