Bigger tits

You openly stare at Jess's rack as it bounces gently from the rough road.

"Hey, eyes front mister!" Jess protests, noticing your leering gaze.

"Calm down," you think at her, praying silently for success. Jess relaxes and goes back to driving. You breathe a sigh of relief.

"I wish she had huge tits, as big as her head," you think to yourself giddily.

Jess's chest swells rapidly, ballooning quickly to the size of cantaloupes with a fwoomping sound. Her white shirt is rapidly stretched to the limit as it tightens around her generous bust. Her buttons strain, struggling to hold each side of her shirt together. Gaps begin to widen around each button. Swelling breast flesh fights to spill through the holes. Jess adjusts her bra through her shirt, clearly uncomfortable with her new endowments, but still doesn't seem to notice anything has changed.

You aren't quite satisfied yet. Jess's melons are definitely big, but have the deflated and sagging look that naturally plagues mature women. While the front of her white office shirt is being stretched to the limit, the area covering her cleavage merely hangs limp.

"Would be nice if she filled out her shirt a bit more"

Jess's breasts inflate, filling the remaining space inside her shirt. The tops of her jugs rise upwards and push firmly against the limp fabric, stretching it taut. Two perfectly round spheres now rest heavily on Jess's chest, jostling enticingly with every bump in the road. Her full, healthy orbs look out of place against the rest of her aged appearance.

"I wish her body was 10 years younger"

You see the skin on Jess's face and arms tighten. Her wrinkles disappear and her hair regains a healthy sheen. She sits up straighter, and even seems to grow a little taller. Her enhanced jugs become perkier, bouncing even more noticeably than before with each disturbance from the road. Your cock begs for attention and you can't resist clutching it through your pants.

"What are you doing?!" Jess exclaims, not looking away from the road.

"You're aroused by me watching you," you think at her.

"Oh!"

Instantly, Jess's face flushes and her nipples spring to attention inside her shirt, tenting out the fabric. Her expression becomes pained and conflicted as she fights an internal battle of lust versus professionalism. You slide your pants down enough for your hard cock to pop out. You shimmy your hips so that it waves around, teasing Jess. She squirms in her seat, grinding her thighs together and moaning softly.

"You need to touch it"

She reaches over with one hand and gently grasps your cock, not daring to do anything else with it. The bumps in the road cause your dick to jostle in her hand arousingly. Your eyes lock onto Jess's huge jugs. They bounce in tandem with your cock.

"Grow your tits bigger, and notice it this time," you encourage her.

Her huge breasts obediently swell even larger. Jess's collar and first 2 shirt buttons explode off of her, pinging against the windshield. She gasps in shock and slams on the brakes. You brace yourself against the dash as the taxi comes to a screeching halt. A trailing car beeps angrily as it swerves around the obstruction.

"Did you do that?!" she asks amazed, still gripping your cock.

You nod.

"Do it again! It feels wonderful!" she demands. You grin excitedly at her.

"Bigger," you think at her tits.

Her jugs lurch forward again an inch. 2 more buttons ping off the windshield, exposing her valley of bubbling cleavage. Her shirt untucks itself at the waist, shifting up to cover her giant breasts. Jess curses lustfully and snakes her other hand between her thighs.

"The bigger your breasts get, the more horny you are," you tell her mentally.

Jess closes her eyes and rubs herself between her smushed thighs. At the same time, she begins slowly stroking your cock.

"Bigger" you command, speaking out loud this time.

Jess moans as her breasts instantly burst 3 more buttons off her top, pulsing up to the size of watermelons. Her thin black bra becomes visible at the center of her cleavage. She pinches an erect nipple between her fingers, groaning with pleasure.

"Pulse them a cup size larger each second until your bra snaps!" you practically shout.

As you described, Jess's breasts rapidly swell a full cup size larger, and then come to a wobbling halt. Jess bites her lip and strokes your cock faster.

A second passes and her jugs surge another cup size larger. The remaining buttons all burst off. Jess's shirt is draped over her humungous rack like an opened jacket.

Fwoomp - another surge. Jess moans louder and squirms in her seat. Her shirt completely loses its grip on her swelling jugs and is pushed to the side. The thin black bra underneath looks more like a bikini now, barely holding on to her supernatural orbs.

Then suddenly with a SNAP, Jess's breasts break free of her bra, jiggling wildly. She moans erotically as they continue growing. They swell into the steering wheel and squash against it, bubbling upwards. Jess pumps your cock furiously, looking at you with unbridled lust. You reach over and grab the side of her massive swelling breast, kneading the soft flesh in your palm. You skirt around and tease her erect nipple through the spokes of the steering wheel. Jess coos with intense approval as you flick your fingers over the spongy protrusion. You feel your balls churning.

"Cum," you tell her.

Instantly Jess emits a high pitched moan and her body shudders as she's wracked by orgasm. She doesn't stop pumping your cock and you feel your balls tighten.

You erupt, spewing rope after rope of cum all over the taxi dashboard. Your cock pulses away in Jess's hand, her stroking only slowing long after the last dregs of seed have spilled down your shaft.

"Wow... now that was somethin'" Jess breathes.

"Hell yeah," you agree, slumping back in your seat.
