Ricky grows his new girlfriend!

"It was my idea!" Ricky reminds her, grinning. "Of course I will!"

"Well then, little guy," Natalie teases back, leaning in to flaunt her size advantage. Ricky's dick throbs as her hot, sweet breath washes over him, her sultry words like music to his ears. "I hope you're a big enough man to press that spacebar." She winks and turns away, walking in front of the gigantic ray before turning back to face him.

Fuck she's huge. And I'm about to make her even bigger, and who knows what else. He can't quick squash the feeling of anxiety welling up from within him. She'd selected just about every option his dad had programmed into this machine, and he had no idea what it was going to do to her... but he's not thinking with his head. He clambers up onto the keyboard, climbs atop the spacebar, and jumps with all his might.

The machine hums, crackles of energy surging up the cables and sparking between the fins of the ray, a ball of light building at the tip... and then like a bolt of lighting, it surges towards Natalie, contacting the tip of her cock and coursing through her body. She screams as the wildest pleasure she's ever known overwhelms every sense, consuming her mind completely with its sheer power!

Ricky watches, his heart pounding with arousal and fear as his longtime crush just stands there, electricity writhing across her body... and then he sees it. "Natalie! You're growing!"

It's barely noticeable at first, but it quickly intensifies, her body spurting upward an inch a second. Not just taller, Ricky realizes. Bigger in every way, and then some! Her breasts swell visibly, filling out, rounder and plumper with every passing moment. Her hips too, quickly widening beyond the formerly slim figure she'd held, along with her thighs. Those gigantic nuts of hers are almost visibly churning, their dark bulk swelling bigger and fuller along with her horsecock, the tip of which seems to be getting closer despite Natalie standing in place! It's throbbing wildly, her screams and moans of pleasure louder and louder!

She can't hold it back anymore! With a shriek from her, Natalie's cock bucks powerfully and fires an enormous jet of semen right into the machine's firing array, bolts of electricity following the cum right back to its source. The screen above Ricky flashes red, loud cracks and pops drowning out Natalie as smoke begins to billow from the machine. Spurt after spurt douses it, smothering any fire that might break out, what seems like an entire sea of jizz dripping from the machine and pooling onto the floor. Ricky just stares in shock as her growth wanes and her cock throbs, belching a last few shots of girl jizz onto the floor. "FUCK!" He screams, flopping back down onto the now-dead keyboard.

Natalie takes a bit to recover, her hands planted on her thighs as she pants through the afterglow of the biggest orgasm she'd ever had. "Ricky... Ricky, it worked!" She wheezes, a dumb smile on her face. "I'm bigger! I've gotta be... like... like..."

Her voice trails off as she looks up and sees the broken machine, smoke still rising from its cum-drenched carcass. "Oh, shit."
