Obsession Unlocked

The medical suite was cool and brightly lit. Dr. Glasscock had you both drop the short robes the moment the door sealed. You stood side by side on a low platform while she moved around you with a tablet and precise measuring tools, completely professional and completely unfazed.

“Hold still,” she murmured.

She measured Stephie first. Soft gloved fingers lifted, turned, and recorded. When she finished she stepped back and displayed the results on the wall screen.

Subject B – Stephie

Flaccid: 6.0 in length × 4.67 in girth

Erect (projected): 8.0 in length × 5.75 in girth

Then she turned to you. The same careful measurements. The numbers appeared beside Stephie’s a moment later.

Subject A – Guest

Flaccid: 3.3 in length × 3.5 in girth

Erect: 5.125 in length × 4.67 in girth

The two columns sat side by side in clean white text. The difference was immediate and brutal. Stephie’s soft cock was already longer and thicker than your fully hard one. Her projected erection dwarfed yours in every dimension. On her five-foot-three, one-hundred-twenty-pound frame the disparity looked even more extreme.

Dr. Glasscock tapped the screen once, highlighting the gap.

“Significant differential,” she said calmly. “We’ll proceed with the complementary optimization protocol.”

Two syringes of shimmering pearlescent fluid were prepared. The needle slid into your left thigh with a brief sting; the same injection went into Stephie’s. Cold fire spread upward into your groin. Your average cock gave a heavy twitch and began to harden fully, already leaking. Stephie’s thick cock, still only half-hard, swelled further under the serum until the heavy eight-inch length and nearly six-inch girth stood out obscenely from her slender hips.

“Informational reinforcement,” Dr. Glasscock said, dimming the lights. A large screen lit up at the foot of the platform. “Eyes forward. Do not look away.”

The video began.

Soft pink and lavender lighting. Slow, looping close-ups of a massive cock—thick, veined, heavy—resting against a small, toned, feminine body. Hands (sometimes masculine, sometimes feminine) stroking it, weighing it, struggling to wrap around the girth. The camera lingered on the way the heavy shaft looked on a petite frame, then cut to side-by-side comparisons with clearly smaller cocks.

A calm, layered female voice whispered over the footage:

Look how big it is on her…

So much bigger than yours…

You want to touch it again…

You need to touch it again…

Crave the weight…

Crave the size…

Her cock is better…

Her cock is what you think about now…

Every few seconds the screen flashed a clean graphic of Stephie’s exact measurements beside your own, the gap glowing softly. Intercut with the numbers were first-person shots of someone on their knees, staring up at a thick cock that looked identical to Stephie’s, the camera lingering on the way it dwarfed the viewer’s smaller hand.

Your own 5.125-inch cock strained and leaked. The serum made every pulse feel sharper, hungrier. The obsession that had started in the villa bathroom deepened with every loop of the video until it was no longer a new curiosity—it was a need. You could still feel the memory of her soft cock filling your hand, the weight of it, the heat. The video promised that hard it would be even more overwhelming, and the serum made that promise feel like the only thing that mattered.

Stephie watched the screen with parted lips, her massive cock fully hard now, eight thick inches standing heavily from her lithe body, the head already shiny. She glanced at you once and gave a small, knowing smile, clearly aware of how fixed your eyes had become on her.

The video continued for a long time—size comparisons, soft commands to crave, slow footage of smaller hands stroking thicker cocks—until the narration finally faded and the screen went dark.

Dr. Glasscock switched the lights back up. Both of you stood flushed and breathing harder.

“That’s enough for tonight,” she said. “Return to your villa. The serum will keep working. You’ll find your thoughts returning to the size differential frequently. That is intentional.”

The walk back felt even more unreal than the walk there. Every step made the heavy outline of Stephie’s cock move under her short robe. Your own average erection ached, feeling smaller with every remembered number on the screen. The hypnosis and the serum had done their work: the only thing you could think about was getting your hands on that eight-inch cock again, feeling the full 5.75-inch girth stretch your fingers, watching it look even more massive against her petite body.

Stephie noticed the way your eyes kept dropping. She let her hip brush yours deliberately, the thick shape under the robe pressing against your thigh for a long moment.

“Still can’t stop thinking about it?” she asked quietly, voice low and pleased. “Good. That means the first session worked.”

You walked the rest of the way in silence, the craving settled deep in your gut, your smaller cock straining against the robe, the Caribbean night air doing nothing to cool the heat under your skin as the villa came back into view. The obsession was no longer new. It was the only thing left in your head.

The villa door closed behind you with a soft electronic click. The ocean stretched black and endless beyond the glass wall. Moonlight silvered the California King and the clear glass shower where this had all started only hours earlier.

Stephie didn’t bother with lights. She simply shrugged the short robe off her shoulders and let it fall. At five-foot-three and a lean one hundred twenty pounds, her slender, toned body looked almost fragile in the moonlight—until your eyes dropped between her thighs. The eight-inch cock hung heavy and half-hard, already thickening under your stare, the 5.75-inch girth looking almost brutal against her narrow hips. The thick head was already shiny.

Your own 5.125-inch cock strained against the robe, leaking steadily. The serum and the hypnosis video still pulsed behind your eyes. Her cock is better. Her cock is what you think about now.

Stephie noticed the direction of your gaze and gave a small, crooked smile.

“Go ahead,” she said quietly. “You’ve been dying to since the bathroom.”

You dropped to your knees so fast the impact stung. Up close the size difference was even more overwhelming. Her cock was already longer soft than yours was hard; fully hard it would dwarf you completely. You wrapped both hands around the thick shaft—fingers unable to meet around the girth—and simply held the weight of it for a long moment, feeling it pulse and swell in your grip.

Stephie watched you from above, one hand resting lightly on your head, blonde hair falling around her face.

“Look at you,” she murmured. “My average little work husband on his knees for the bigger cock. Never thought I’d see the day.”

You leaned in and pressed your lips to the thick head, kissing it once, then again, tasting clean skin and the first bead of precum. The scent of her filled your nose—soap, heat, and something musky that the serum made intoxicating. You opened your mouth and took the head inside. Even just the tip stretched your lips wide. The heavy weight of it on your tongue made your own smaller cock throb and leak onto the floor between your knees.

You tried to take more. The thick shaft pushed your jaw open further; the 5.75-inch girth forced your lips into a tight, shiny ring. You only managed a few inches before the head nudged the back of your throat and you gagged. Spit ran down the remaining length. Stephie sighed above you, hips giving a small, encouraging push.

“That’s it. Worship it. You’ve been obsessed since you first saw it. Show me how much you need it.”

You obeyed. Wet, sloppy, desperate. Both hands stroked the thick inches you couldn’t fit in your mouth while you sucked on the head like it was the only thing that mattered. Every time you glanced up you saw the same impossible contrast: her petite, toned body and the massive cock stretching your lips. Every time you glanced down you saw your own average cock—five and an eighth inches—looking almost delicate in comparison, shiny with precum and completely ignored.

Stephie grew fully hard under your attention. The full eight inches stood out from her slender hips like a weapon, the thick veins standing out under the stretched skin, the head flushed dark and constantly leaking onto your tongue. She began to rock her hips in short, shallow thrusts, fucking your mouth with just the first third of her cock while you moaned around it like a man starving.

“Look at the size difference,” she whispered, one hand tightening in your hair. “Eight inches. Almost six around. And you’re barely over five. No wonder you can’t stop thinking about it. No wonder the serum made you crave it so bad.”

You whimpered around her cock, the sound wet and needy. Your own smaller cock bounced against your stomach with every movement, untouched, aching. The humiliation of the size gap only fed the craving. You wanted to stay on your knees. You wanted to feel the weight of her on your tongue until your jaw locked. You wanted the thick head to push deeper even if it made you choke.

Stephie pulled free with a wet sound, a thick string of spit connecting your bottom lip to her cock. She was breathing harder now, the massive shaft glistening from root to tip.

“Bed,” she said. “On your back. I want to watch your face while you keep worshipping it.”

You scrambled onto the California King. She climbed over you, knees bracketing your ribs, and let the heavy cock rest against your lips again. From this angle it looked even larger, the thick shaft rising from her small, toned body like it belonged to someone twice her size. You opened your mouth and took her back in, hands stroking the remaining length, eyes locked on the place where her slender hips met the impossible girth.

Stephie fucked your mouth in slow, controlled strokes, never giving you more than you could take, but never letting you forget how much bigger she was. Every few thrusts she pulled back just far enough for you to see the shiny, spit-slick shaft and the way it dwarfed your own leaking cock below. The visual made your average dick twitch and spill another clear bead onto your stomach.

“Good boy,” she murmured, voice low and pleased. “Keep sucking. Keep craving it. This is what the first session was for.”

You stayed there for a long time—mouth stretched, hands worshipping what you couldn’t swallow, smaller cock untouched and desperate—while the ocean murmured beyond the glass and the serum kept the obsession burning hotter with every thick, heavy pulse against your tongue.
