Harem Training System: Every Girl I Train Makes Me Stronger!

He began to move, and the rhythm was relentless. He wasn’t just fucking her; he was claiming her, each thrust deep, hard, and punishingly precise.

PLAP! PLAP! PLAP! CREAK!

The bedframe creaked violently beneath them, accompanied by the wet, rhythmic plap, plap, plap, and slap, slap, slap of his pelvis grinding against her swollen clit and thighs.

"Nnngh~! AHHHH! OH GOD!" Catherine’s screams dissolved into a stream of incoherent, high-pitched moans. "IT’S HEREEEEE~! IT’S HEREEEEE~!"

"OH FUCK, WILLIAM, IT’S HEREEEEE~!" Her hips bucked upward instinctively, trying to meet every punishing stroke, trying to swallow every inch of him. "AAAAHHHHH... AMAAAAAZZIIING~! OH FUCK, YES~!"

As the friction intensified, the heat between them became almost unbearable. The oil acted as a perfect lubricant, making every slide feel impossibly slick and searingly hot.

Catherine’s mind began to fracture under the pleasure, her voice taking on a delirious, theatrical quality as she leaned into the fantasy of her own arousal.

"E-excuse me... ahhnnn... what kind of effects will this... ahhnnn... have on my body?!" she cried out, her voice wavering between a sob and a moan as she slipped into her roleplay. "Am I... am I being corrupted?"

"Is this... ahhh~ fuck, is this magic?!"

"My insides feel like they’re melting! Nnnnngh~ I can feel you touching my soul, William!"

"Ahhnnn~ mmmph~ more! More of the magic! FUCK ME HARDER~!"

William didn’t give her a moment to breathe. He gripped her hips with bruising force, his fingers digging into her soft flesh to anchor her as he picked up the pace.

The sounds coming from her were a chaotic storm: wet squelches, guttural screams, and desperate, needy whines.

"You want to know what it’s doing to you?" he growled against her ear, his breath hot and ragged. "It’s turning you into mine."

"Every thrust is marking you."

"YES! YES~!" she shrieked, her voice cracking. "Mark me! Destroy me~! AAAAAHHHHH! OH GOD, YESSSS~!"

The friction between them had escalated beyond mere lust into something primal and almost competitive. Catherine, driven by a desperate need to keep him anchored to her, wrapped her powerful thighs around his waist.

She locked her ankles behind his lower back in a vice-like grip, her legs clamping down on his hips to ensure he couldn’t retreat even an inch. The position forced him even deeper, every thrust now carrying the full weight of his muscular frame.

William let out a guttural roar of approval. "Fuck, Catherine, you’re not letting me go, are you?"

To counter her grip and increase his own leverage, he planted both palms flat against the mattress beside her head. His triceps corded like steel cables as he pushed off the bed, using the floor as an anchor to drive his hips upward with devastating force.

The mattress groaned under the strain as he hammered into her.

"This is part of the treatment, remember?" William grunted between ragged breaths, his sweat dripping onto her chest. "This level of intensity... it’s going to raise your body temperature and burn off all that belly fat!"

"Think of it as the ultimate workout; it’s perfect if you’re on a diet!" He paused for a split second to glance down at her glistening, toned stomach before continuing his relentless assault. "But honestly? There’s nothing to burn."

"You’re already fucking perfect."

Catherine’s face flushed a deeper shade of crimson, her expression one of pure, unadulterated ecstasy mixed with genuine delight.

"Oh my—really—ahhh—mmmph—William!" she squealed, her voice climbing an octave. "You’re such a... ahhh~ dirty liar, but I love it! Nnnngh~ YES~ MORE~!"

William didn’t slow down; if anything, he became more methodical, each thrust aiming to hit that same sensitive spot deep inside her.

"Don’t just lie there taking it," he commanded, his voice dropping to a commanding growl. "Try to focus on the lower part of your belly."

"Right where I’m hitting you... Apply strength to it! Contract those muscles!"

"It’ll create a tightening effect that’ll make this feel insane for both of us!"

Catherine gasped, her eyes snapping open as she tried to process the instruction through the haze of pleasure. "Focus... lower belly... okay~ okay~ I’ll try~ ahhnnn~!"

She gritted her teeth, sucking air through her parted lips as she focused every ounce of her willpower on her pelvic floor muscles. She imagined herself squeezing around him, trying to trap his cock within her walls.

The effect was immediate.

William’s eyes widened as he felt her internal muscles suddenly constrict around his shaft. It wasn’t just a flutter; it was a powerful, rhythmic clenching that seemed to wrap around every ridge of his cock.

"Yes~ yes~ oh fuck~ yes~!" Catherine screamed, her head thrashing side to side. "Like~ like this? How is IIIT?"

"Am I doing it right~? Oh god, William, I can feel you inside me so much more now!"

"AHHHH~ mmmph~ hoouuuhhh~!" Her pussy felt like it was actively milking him, the wet squelching sounds becoming faster and more desperate as her contractions intensified.

William gritted his teeth so hard his jaw muscles bulged. The sensation was overwhelming; it felt like his cock was being squeezed by dozens of warm, velvet hands simultaneously.

The suction was immense, and he could feel the blood pooling at the tip of his cock, responding to the intense pressure. He felt like his cum was already halfway up his urethra, desperate to escape the punishing grip of her cunt.

"Fuck, Catherine..." he hissed through clenched teeth, his hips stuttering for a moment as he fought to maintain his rhythm. "That... that’s fucking incredible."

"But you’re cheating! You only tightened it a little, but it’s already making me feel like I’m about to cum!"

"Nooo~ don’t cum yet~!" she whined between moans, her legs tightening even harder around his hips, refusing to let him escape the delicious torment she was inflicting on him. "Keep going~ keep fucking me~ ahhhnnn~ mmmph~"

PLAP! PLAP! PLAPPPPP!

"YES~ RIGHT THERE~!"

The intensity in the room was reaching a fever pitch, the air thick with the scent of sweat, massage oil, and raw arousal. William was operating on pure instinct now, his body moving with a relentless, piston-like force that left no room for hesitation.

As he continued to hammer into her lower body, he reached up with his left arm, his large hand finding one of Catherine’s massive breasts. He squeezed it hard, his fingers sinking into the soft, pale flesh, rolling her nipple between his thumb and forefinger to keep her nerves screaming.

But he wasn’t done exploring her. While his hips maintained their punishing rhythm below, his right arm reached upward.

Catherine instinctively parted her lips, and William slid his fingers into her mouth. He didn’t hesitate, using his fingers to explore the slick heat of her inner cheeks and the sensitive underside of her tongue.

He teased the roof of her mouth, his knuckles brushing against her teeth as he worked to overwhelm every single one of her senses at once.

Catherine let out a muffled, delirious sound, a mix between a whimper and a purr. The dual stimulation was sending her into another dimension; her pussy was clamping around him in desperate waves while her mouth was being thoroughly invaded.

Despite the roughness, she felt an overwhelming sense of surrender, a deep relaxation that came from being completely claimed by him.

"Mmmph... nnnnh..." she managed to gurgle around his fingers, her eyes half-lidded and glazed with pleasure.

She pulled one of his fingers out just enough to speak, her voice dripping with honeyed need. "Umm... since you were so kind before..."

She paused to drag her tongue along his thumb, licking it with slow, deliberate strokes that made William’s cock twitch violently inside her. "Can I ask you... mmmph... to continue the facial massage from before?"

William froze for a heartbeat, a dark smirk spreading across his face. He knew exactly what she meant.

She wanted him to paint her face with his cum again, to claim her mouth as his canvas one more time.

Without needing another word, he shifted his weight. He released her breast and lunged forward, lowering his upper body until his chest pressed against hers. He captured her mouth in a kiss that was less of an embrace and more of an assault.

Their tongues tangled fiercely, tasting each other amidst the salt of their sweat. The kiss was desperate and hungry, a collision of mouths that drowned out everything else.

The room became a chaotic symphony of obscene sounds. Below them, the wet, rhythmic slap, squelch, slap of his cock driving into her pussy continued unabated, punctuated by the creaking of the bedframe.

Above them, the wet, sucking sounds of their deep, messy kiss mingled with Catherine’s muffled moans.

"Nnngh~ mmmph~ ahhhn~!" Catherine cried into his mouth, her hands flying up to grip the back of his neck, pulling him closer as if she wanted to merge their bodies entirely. "Yes~ fuck~ yes~!"

Every time William thrust deeper, a fresh wave of sound erupted from her, a guttural moan that turned into a high-pitched squeal when he hit her deepest spot.

"AAAAHHH~ NNNGH~ OH GOD, WILLIAM~!" The combination of the deep, internal friction and the overwhelming sensation of his mouth claiming hers pushed her to the brink of madness.

She was caught between two fires: the pounding heat between her legs and the consuming hunger of their kiss.

"Fuck, Catherine..." William growled against her lips, breaking the kiss just long enough to breathe before diving back in. "You’re going to be completely ruined by the time I’m done with you."

"Please~" she gasped, her voice breaking as she arched her back, her inner walls clenching around him in a frantic rhythm. "Ruin me—destroy me—!"

"AHHHHHH~ mmmph~ YES~ FUCK ME HARDEEERRRR~!"
