Caleb unpacked the final items from his suite case and placed them on the bed. He was tired, and hungry. He spent the last hour settling into his room before pondering what he wanted to eat. He would go out to eat. It was also a great excuse for you to accompany him. Great idea, he thought to himself before leaving his room.
“Hey, pipsqueak, wanna go,” Caleb leaned in your doorway, frowning at your absence. Your bedroom light was on, warm vanilla scented candle lit, and your pillow lay at the end of the bed. “Pip?” he called out. No response.
“Where the heck did you go?” Caleb questioned to himself. That is when he noticed it. A book laying at beside the pillow at the end of your bed. “What could you be reading?” He ponders as he approaches the bed. The book was split open and faced down with the title gazing back at him. The front cover was monstrous furry creature (like a werewolf) embracing a beautiful young red-headed women, with the title, “My Downfall, the Monster inside me.”
A curious grin grew across his face as he picked up the book to inspect it. He turned it over to read the page you were on. “No idea you were into fantasy” he chuckled under his breath. That is when all the blood rushed through his body when he realized what scene you were on.
“Lucius’s razor-sharp fingertips dug into your hips, holding you firmly in place as his hot, wet tongue flicked over your nipples. The air was filled with the slick, obscene sounds of his relentless thrusts, each one sending shockwaves through your trembling body.”
As Caleb’s eyes scanned the text, a surge of heat pooled low in his abdomen. He had no idea you were into this kind of thing. In fact, he barely knew what you liked at all. The two of you had kissed twice—only twice—and never spoke of it again. You pretended it never happened, and he had respected your silence. He even gave you space for a few weeks while he returned to the fleet. He always assumed you were shy about these things. But this... this was beyond anything he could have imagined.
A sudden emotion crept up his spine, curling around his chest—jealousy. The book spoke of a monster with a massive cock while it plummeted a young woman. Was this what you fantasized about? The thought gnawed at him. How could you entertain the idea of someone—something—other than him? How was he supposed to compete with a fantasy?
Caleb snapped the book shut. At that exact moment, you walked into your room, soda in hand—only to freeze in place. His face flushed with a deep red, eyes wide with shock, the book trembling slightly in his grip. Before he could say anything, you stormed towards him – ripping the book from his hand.
“What the fuck Caleb! Do not snoop through my stuff.” You huff in annoyance, shoving the book under your pillow with a sharp motion. Your cheeks seared with hot embarrassment.
“Don’t snoop through your stuff? You left it out in the open.” He gestures towards the bed with his arm.
You roll your eyes, but deep down, embarrassment burns through you. Your heart pounds relentlessly—how much did he read? You had only stepped away for a soda before getting to the good part, but of course, Caleb had to snoop. Just this one time, really?
As you fume internally, you suddenly notice his eyes locked onto you. Unmoving. There is something in his gaze—something unreadable. It is as if he wants to say something but cannot force the words out. “What do you want?” You question.
Caleb’s gaze drags over you, slow and deliberate. His eyes darken with something unreadable, a flicker of curiosity dancing in them. He steps closer, towering over you, his presence suddenly heavier—more intense.
“I was going to ask if you wanted to grab some food…” His voice is lower than usual, edged with something husky, something almost teasing. “But it looks like you’re preoccupied.”
It’s different from his usual kindred tone—there’s something else laced in it. Something… sensual.
Your brows furrow, but before you can utter a word—you notice it. The height difference. It had never been a problem before. Why would it be? If anything, it was the reason behind your old nickname, 'Pipsqueak.' You’d always been significantly smaller than him, short enough to be teased most of your life. But Caleb had never let anyone ridicule you—he defended you, made you feel beautiful, made it clear that, in his eyes, you were perfect.
But now… now, as he loomed over you with that unreadable, almost menacing gaze, something felt different. The sheer size of him, the way he looked at you—it sent a shiver down your spine. Suddenly, you felt small in an entirely new way.
As if he could dominate you at any second. He looked like a monster compared to you.
A slow heat curled in your belly, pooling low between your legs.
Caleb gazed down at your tiny frame, a familiar sense of protectiveness stirring in his chest. You had always been so cute to him—adorable, even. But lately, it was more than that. Your curves teased him relentlessly, drawing his eyes no matter how hard he tried to resist. The way your hips hugged those sweat shorts. The way your tight white T-shirt clung to your breasts.
Maybe… just maybe, he could be the monster you craved.
Why lose yourself in fantasy when you had him—your fantasy?
A slow smirk tugged at his lips as he stepped forward, his presence overwhelming. You instinctively backed up, only to find yourself sinking onto the bed. Caleb followed, towering over you, his gaze burning with something new.
“Pipsqueak,” he murmured, voice smooth and husky, dripping with amusement, “do you read those books because of me?” He leaned in, close enough for his breath to ghost over your skin. “If you wanted to cross that line, you could have just asked.”
His words melted through you, leaving you utterly undone.
He cups your chin, drawing you into a deep, urgent kiss. His lips move over yours with a hunger that speaks of years of pent-up longing, his touch both possessive and desperate. His thigh slips between your legs as he presses his body flush against yours, the heat of him sinking into you. Every kiss, every touch, feels like he’s devouring you whole.
Your hands slip beneath his shirt, fingertips exploring the firm ridges of his abs, the sculpted lines of his chest, the solid curve of his shoulders. His body responds, pressing closer, the friction sending a delicious shiver through you. His mouth leaves yours, trailing down your jaw to your neck, his lips and tongue igniting fire along your skin. A breathy gasp escapes you, your body arching into him as heat pools low in your belly.
You have dreamt of this -of him- of the way he would feel against you again. But this… this is beyond anything you ever imagined.
“Mmghmm,” he groans against your skin, his voice thick with desire. “Fuck, baby -ah- I’ve wanted you for so long.”
Baby. You have never heard him call you that. His words alone send a sharp pulse of need straight to your core, your body aching for him. As he buries his face in your neck, you tilt your head, lips finding his ear. Slowly, you trace the shell with your tongue, savoring the way he shudders beneath your touch. Your fingers slide into his hair, gripping, tugging just enough to make him gasp.
And then, you feel it- the tension, the fire, the sheer desperation radiating between you. Neither of you can hold back much longer.
You both move in a frenzy, hands desperate, yanking at each other’s shirts until the fabric tears. Clothes hit the floor in seconds, leaving nothing between you. Caleb’s gaze drops to your bare chest, and something in him snaps. His jaw clenches, his breath shuddering as his fingers trail over your soft skin, almost reverent—almost broken.
His hand glides down your stomach, fingers teasing the edge of your shorts before slipping beneath the fabric. The moment he touches you, his breath hitches—his fingers pressing into the heat of your slick, aching core.
“Fuck,” he groans, his voice rough with desire.
A sharp gasp escapes you as his fingertips brush over your swollen clit, sending a pulse of pleasure through your body. Your hips shift instinctively, chasing his touch.
“Mnnghnn—Caleb,” you moan, your voice trembling as he circles the sensitive bundle of nerves, drawing out another needy whimper.
His eyes meet yours, and there’s darkness in them. His fingers circle your clit.
“Fuck, you’re so wet… but are you wet for me, or that monster you wanted to fuck?”
Your eyebrows crease, “Caleb, it’s just a fantasy book.”
Caleb’s fingers abruptly stop, leaving your core aching for more. “I want to be the only one who makes this pussy wet.”
He presses his fingers, dragging them around your opening. “Tell me baby,” he growls, “is this all for me?”
He begins to peel your shorts and underwear off. Your hands grip your thighs, “Y-yes.”
“Say it,” he dips his head towards your clit and traces his lips barely touching your clit, “say you’re mine.”
Your breath catches, the words escaping your twitching lips, “Oh god yes – I’m yours.”
His lips crash into your lips, feverously kissing your nerves while slipping one finger into your cunt. Overwhelmed and arching, you pant loudly in consuming pleasure. “Fuck Caleb - I want you so bad.”
“So fucking wet,” he groans, his tongue circling your clit in slow, teasing strokes. “I could play with this pussy all night.”
Just as the words leave his lips, he presses another finger inside you, the stretch sudden and deliciously overwhelming. His pace quickens, fingers curling right as his tongue works in sync, sending waves of pleasure crashing over you.
“Mmmghhmmm—C-Caleb, yes,” you cry out, your breath hitching as your body tightens around him, lost in the relentless pleasure he’s giving you.
Just as you are teetering on the edge, he suddenly stops, pulling his fingers from you, leaving you aching and desperate. A wicked smirk tugs at his lips as he stands, eyes dark with lust.
Without breaking eye contact, he hooks his fingers into the waistband of his pants and peels them off, letting them fall to the floor.
Your breath catches. He is huge—thick, veined, and heavy, his cock standing hard and proud, the swollen tip already glistening with need. The sheer size of him makes your thighs clench instinctively, heat pooling between them.
"You're not the only one who's desperate tonight, baby," he murmurs, stroking himself slowly, teasing you with the sight. "Now, be a good girl and show me just how much you want this."
Your breath catches as he strokes himself, his thick, pulsing cock teasing your slick folds. The anticipation is unbearable. Caleb climbs over you, gripping your thighs as he lines himself up. The swollen head presses against your entrance, spreading you open inch by inch.
"Fuck," he groans, dragging the tip along your heat. "You’re so damn wet for me."
Then, with one slow, deliberate thrust, he fills you, stretching you around his sheer size. A gasp escapes you as pleasure and pressure intertwine, your body molding to fit him.
"That’s it, baby," he rasps, his breath hot against your skin. "Take all of me."
And then he moves—deep, slow, claiming you completely.
With a sudden jerk, he grabs your legs and lifts them onto his shoulders, folding you beneath him. The new angle has you gasping as he sinks even deeper, stretching you in ways that have your toes curling.
Then, without warning, he snaps his hips forward, picking up speed, fucking you hard and fast. His grip tightens on your thighs, holding you in place as he pounds into you, each thrust deep and unforgiving. The sound of skin slapping fills the air, mingling with your breathless moans and his ragged groans.
"Fuck" he growls, his voice thick with need. "You feel so damn good, taking me like this."
His pace is unrelenting, pushing you closer to the edge with every ruthless thrust.
He pauses for a moment, adjusting his angle, his thick length pressing even deeper. Then, with a sharp thrust, he slams into you again—this time hitting that perfect spot. A broken moan rips from your lips as pleasure explodes through you.
“There it is,” he groans, a wicked smirk playing on his lips. “Gunna cum for me baby?”
His pace turns ruthless, each thrust slamming against your g-spot, sending waves of ecstasy crashing through you. Your body tenses, the pressure coiling tight, ready to explode. Then—his cock slams into that perfect spot again, and you shatter.
A scream rips from your throat as pleasure crashes over you, raw and blinding. Your walls clench around him, gripping him in rhythmic pulses, dragging him deeper as your body trembles uncontrollably. Your nails rake down his back, your breath stuttering as wave after wave of ecstasy leaves you shaking, ruined, and completely his.
Caleb groans, feeling your walls tighten around him, milking his cock with every desperate pulse. His grip on your thighs tightens, his rhythm faltering for a moment as he watches you unravel beneath him.
“Fuck- just like that,” he growls, his voice rough and strained. “You’re so damn tight, baby. Squeezing me so fucking good.”
The sight of you—trembling, wrecked, completely lost in pleasure—pushes him closer to the edge. His thrusts turn frantic, desperate, chasing his own release as he watches you come undone beneath him.
Caleb’s thrusts turn wild, his cock throbbing as your tight, pulsing walls milk him mercilessly. A deep, broken groan rips from his chest as he slams in one last time, burying himself to the hilt.
“Fuck- take it, baby, gunna cum-” he growls, his grip bruising on your hips as he spills inside you, thick and hot. His whole body shudders, hips jerking as he fills you to the brim, his cum leaking out around his cock with every desperate pulse.
His head drops to your shoulder, his breath ragged, voice wrecked. “You’re so fucking perfect- made for me,” he mutters, his fingers still gripping your thighs, like he cannot bear to let go just yet.
Caleb rolls off you, but before the warmth between you fades, he pulls you into his arms, holding you close. His heartbeat is still erratic against your skin, his breath warm against your hair. Then, with a lazy grin, he lifts his pinky, hooking it around yours.
“Pinky promise it won’t be weird after this?” he teases, his voice husky but light. Your pinky meets his, locking in an eternal agreement. Your lifelong crush is now officially yours. He always was—deep down, you knew it—but hearing the words, feeling his touch, makes your heart ache in the best way. Every whispered promise, every possessive touch, every desperate kiss solidifies it. He’s yours. Finally. Completely.
And you never want to let go.
A teasing smile spreads across your lips. “I can’t believe you got jealous over one of my smut books.”
Caleb raises an eyebrow, a dark expression settling over his face. “One of your smut books?” His voice drops, rough and dangerous. “Just how many do you have?” Before you can answer, he rolls over top of you, pinning you beneath him. His weight is firm, commanding, making your breath hitch.
You squirm beneath him, heat rising to your cheeks. “I—I read them all the time,” you confess, voice barely above a whisper.
His lips curl into a wicked smirk. “All the time, huh?” He presses his hips against yours, his voice nothing but a taunt.
“Pipsqueak… tsk. Guess I’ll have to make you feel every single one of those books.”
