A thought popped into Jack's brain almost instantly; he might have a chance of wriggling off the bed, and from there he'd be able to roll underneath, buying himself some time to get free of the tape. Caitlin was definitely getting changed out of her current attire and this was likely to be his only window. Cue frantic squirming, kicking and rolling as he tried to get himself to the edge of the covers before Caitlin returned her attention to him.

He was acutely aware of how ridiculous he must've looked, like a pathetic worm trying to inch its way across a teenage girl’s bed.

Just as his hopes dared to rise as he approached the edge of the bed, he heard her voice cry out, “What the fuck do you think you’re doing?”

The leviathan’s heavy footsteps thumped near as she swooped in to halt his progress and drag him back to the middle of the covers. Her huge face appeared in front of his, not exactly furious but more than a tad annoyed.

“Sneaky little bastard aren’t you?” she smiled evilly, looking down his body to where she was placing her left hand. He strained his heavily-bound neck to see, clocking an awe-inspiring view of her perfectly-developed bod in just a bra and panties. She waited for him to notice where she’d put her fingers; right in position to flick him where it would hurt the most.

Jack’s world exploded as Caitlin’s middle finger delivered a devastating blow to his nutsack; the poor boy screaming again and again in agony as the girl laughed cruelly, amused no end by his suffering.

“Stupid toyboy,” she mused.

“I hate you!” Jack screamed bitterly, “I fucking hate you!”

The big girl pulled a pouty face, pretending to take offence, slid her hands under his writhing form and lifted him in the air by the waist. He again had a front row view of her unbelievable body; pink hipster panties and a matching demi bra left little to the imagination - her tremendous physique seemingly pushing the bra in particular to breaking point.

The powerhouse redhead parked her mammoth backside down on the bed, and held him just in front of her, his feet hanging limply between her knees and his head right in front of hers.

“Can I let you in on a little secret?” she said piercingly, her face simultaneously stern and arresting framed by her long ginger locks. Jack didn’t gratify this with any kind of response, so the giant continued anyway.

“I could have any boy, hell, any man I want, with this body,” she boasted, deliberately pushing her elbows inwards to emphasise her prodigious tits and cleavage.

“However, I realised that fucking with guys was more fun than just fucking them,” she grinned, shaking her hair out of her eyes self-assuredly.

“Plus, none of them stack up where it counts,” she added, raising an eyebrow self-assuredly.

“Men are pricks, even you little Beta runts,” she went on, “It gets me off so much to humiliate you, to make you beg, it makes me feel… powerful.”

As she said this, he felt her flex her muscles, and looked on terrified as her arms, shoulders and neck bulged noticeably.

“Beg me to let you go, come on, it turns me on soooo bad.”

The enormous girl awaited a response, her intimidating physique almost unreal to behold.

“Y-you fucking psycho, you’re s-sick! W-why are you doing this to me?” came Jack’s desperate response, “I never hurt you, I n-never…”

Caitlin squeezed him forcibly, stopping him mid-stammer with a yelp, “Stop whinging, shrimp, don’t you get it? I want you to hate me, it gets me off, I don’t care about you or your feelings.”

Jack began to weep again, “And don’t be such a pussy either,” she growled threateningly, “Or I’ll give you something to really cry about.”

The giant girl idly squeezed and pressed the distraught boy with her controlling hands, causing him to twitch and squirm involuntarily as she sought out tender spots on his miniature body with her strong fingers and thumbs. She could almost place his whole backside in one oversized palm whilst prodding his ribs and torso relentlessly.

After tormenting him for a few moments as he blubbed, she decided to strip some of the tape from his legs, resting him carelessly against one of her forearms whilst ripping the tape off with the other arm. She left a tightly-wound band from his stomach to his shoulders that held his arms by his sides but left his wrists and hands relatively free. Jack spent a lot of the time meekly pleading for her to let him go between sobs, absolutely on the brink of submission and clinging to the hope that he might still be able to get out of this situation by some small miracle. The giantess’ features remained utterly unmoved.

After she’d peeled the last strip from his pant leg, she placed him on the floor like a little soldier just in front of her. Without the use of his arms, Jack didn’t feel very stable, but just as he was about to try and retreat cautiously, a large palm connected with his forehead and sent him tottering rearwards to fall flat on his ass on the carpet.

The leviathan chuckled heartily, her tree-like thighs rippling with muscularity as she stood up with her feet either side of his, it was like looking up at some gigantic, malevolent statue of a Roman Goddess. As the tiny captive tried to gain purchase on the floor with his flailing legs, Caitlin lowered one huge foot onto his body; her heel resting just above his crotch on the sensitive part of his belly, and her pink-capped toes at the top of his chest. She drummed her sizeable toes on his collar bone, the muscles in her lower leg undulating imposingly, and gradually increased the pressure on his chest.

Her hand snaked up her torso to one of her big boobs, cupping it suggestively as she glowered down at him, “I could crush you so easily, toyboy, you know that?”

Jack emitted a wobbly groan as she compacted his lungs with the ball of her foot, his little legs flopping limply as he tried to cope with the strain.

The enormous foot lifted off slightly, allowing him to breathe again, and slid heavily along his body towards his legs, grinding into his junk deliberately with the sole of her foot as it went. Its substantial weight then pressed down on his legs, pinning them against the carpet firmly enough to hinder their wriggling, her toes now resting on his groin.

“Please g-g-get off…” he stammered as she nudged the fly of his trousers with the pad of her big toe. The towering redhead just peered down at him, unsubtly pushing against his stiffening cock through his trousers with a toe the size of an elongated billiard ball.

“You know what, I bet you’re just as sick as you think I am,” she said confidently, “I bet you love this…”

“I d-don’t!” he yelled, “I’m scared, I’m hurt, I w-want to go home!”

His face turned slightly red with embarrassment as the stimulation downstairs began to have the desired effect.

“You’re lying, you little prick, this totally gets you off too,” she breathed, rubbing her nipple through her bra a little with her fingers as she leant directly over him.

“It d-doesn’t, please, you’re forcing me! This is like rape!” he wailed, twisting his body pitifully as his hard-on began to press harder against the fabric of his pants.

“I don’t think your microdick agrees, little Jack,” she sniggered, “Shall we see what he has to say?”

 “N-nooo…” he whined, but Caitlin was already lifting her foot off him and lowering herself down, tucking her well-built legs underneath her body as her long red hair swept across her face. Elephantine fingers attached themselves clumsily around him, effortlessly lifting him from the floor like a child’s baby doll, then dumping him unceremoniously on his back on a corner of the giant bed.

The duvet cover was thankfully very soft, cushioning the landing, but respite was brief as immediately an outstretched hand big enough to hold a 12-inch dinner plate forced his thighs flat whilst the other started to roughly yank off his shoes.

Jack yelled out in pain as he she twisted his ankle carelessly, plucking off his little socks and dropping them on the floor next to his shoes.

“Don’t undress me again, Caitlin! Please!” he pleaded despairingly.

“Shhh, peewee,” she soothed disingenuously, already sliding her suppressing hand up to his chest and grasping at his waistband with her invasive fingers. Despite his frantic wriggling, she easily tugged his britches down around his ankles, and before he knew it she had, for the second time in as many days, stripped him of his dignity in the most uncomplicated fashion.

The giant girl gasped in false amazement, aiming to be as disparaging as she possibly could.

“Oh tiny, is this for me?” she cooed, placing a heavy fingertip on his shaft and squishing it sideways onto his inner thigh, making him groan protractedly as the incompatible sensations of embarrassment and arousal battled in his mind. His penis was rock hard, painfully so; he’d never felt himself like this before.

The redhead suddenly laughed out loud, and he strained his neck to look down his body.

“Ha-ha! Your cock isn’t even as big as my pinkie!” she cackled, comparing his boner to her finger.

Humiliatingly, she was right, his little dick was perhaps slightly thicker than her smallest digit, but was nearly an inch shorter.

Smirking, the giant girl grasped his member lightly between thumb and middle finger and delicately pulled on his foreskin, causing Jack to moan as he felt her big index fingertip tap the head of his dick gently. His cock pulsed as she pinched more firmly, watching his face intently to savour the exact moment his pleasure became pain. His little mouth opened slightly as the soft noises he made became more high-pitched and strained as she gripped still harder, twisting it malevolently in her vice-like grip.

Caitlin’s glee was cut short unexpectedly by the sound of her mobile phone ringing from the other end of the room; it was clear from her reaction that she needed to answer it.

Exhaling huffily, the girl stood up and grabbed it quickly, bringing it up to her ear but keeping her focus firmly on the bed – Jack dared not move a muscle, despite the awkwardness of his situation; pants round his ankles and naked from the waist down.

“Hey… yeah. Yep. Ok, whatever…” she clucked in a bored kind of way, cocking her hip and angling her head to her side.

“What… now?” she said incredulously, rolling her eyes, “…Ok, gimme a second already, god.”

She grabbed her sports bag, walked over to Jack and dropped it right onto his body and bare groin with a sickening thud, winding him.

“Don’t go anywhere,” she hissed down at him, holding the end of her phone away from her mouth as she did so. She opened the bedroom door, walked through it and closed it behind her, her voice trailing off as she walked through the house.

Caitlin’s bag wasn’t quite as heavy as Jack had made out; it wasn’t exactly light or anything but his over-exaggerated ‘oof’ had definitely sold the illusion.

Kicking madly, he wriggled his way out from underneath it, then rolled off the duvet cover onto the floor, landing on his feet and immediately letting his back fall against the side of the bed so he didn’t topple over. Despite having his arms pinned to his side with sports tape and his pants round his ankles, he could still try and shuffle around to find an exit or hiding place before she returned.

He was used to being dwarfed by Alpha-scale environments at school, but a teenage girl’s bedroom was a new experience entirely – he was completely out of his comfort zone here. Scanning around, he figured that hiding under the bed was way too obvious - she would find him within seconds - so he scuttled towards the en-suite to buy himself some time. His eyesight wasn’t so bad that he couldn’t see where he was going, but it was definitely hindering his ability to spot somewhere to hide.

He got through the door not a moment too soon, as Caitlin’s distant voice approached the bedroom door again and opened it, still in mid-conversation. Unfortunately, there was nowhere obvious to hide in the bathroom where he couldn’t be found very easily, as she didn’t have any kind of cupboard, just a small plastic bin that offered practically zero protection.

“Alright Mum, you don’t have to check up on me every 5 minutes,” her voice protested as she re-entered the room, closing the door and locking it behind her.

“K, bye then…. bye,” she said finally, her phone making a beep as the call disconnected.

“Where were we?” she announced ominously, closely followed by a hesitant “...huh?” as he heard her investigate the bag and lift it up.

“You little shit!” she yelled angrily, “You wait ‘til I find you!”

He felt the floor shake as the gigantic teenager dropped to the floor to check under the bed, and he could hear her arms sweeping around underneath it, bashing boxes and god-knows-what around in her haste.

Treading as carefully and quietly as he could, Jack made his way towards the shower door, which was left tantalisingly open – figuring he could hide behind the door and use the large towel draped onto it as cover. He was still absolutely petrified, because it was a pretty feeble hiding-place, but it was the best he could do in the circumstances.

“Where the fuck are you hiding?!” the increasingly irked giantess bellowed, moving on to the wardrobe, if the noises from the other room were anything to go by. He heard her throwing her clothes around the room, and then her shoes as she stormed around like an angry bear.

Jack tried to tread carefully as he stepped up and across the threshold of the shower. It wasn’t wet, but as it was a very smooth surface, it was hard to get a good foothold without the use of his arms for balance.

The din from the bedroom subsided suddenly, and he froze, trying not to make a sound.

“I know you’re still in here, boy,” the girl snarled menacingly, “And if you don’t come out soon, when I find you, I’ll use you for soccer practice.”

He swallowed audibly, inching his way carefully behind the towel. He heard the monstrous Alpha get to her feet and start throwing her clothes back into a pile.

“It’s only a matter of time before you fuck up...” she began, but never actually finished the sentence, as before she could, the unmistakeable echoed thud of a shampoo bottle falling over in a shower was heard from through the bathroom doorway.
