Ty adjusted his package against his pants, forgetting to adjust his clothing to his new size. But it wasn't just that, the girls trapped inside had a warm, churning effect on his entire crotch. He smirked and descended the stairs to find the source of the loud crashing noises, which so rudely interrupted his fuck session.
Dustin was struggling to open the door, of course Ty had put a magical lock on the deadbolt. With the broken window nearby Ty put 2 and 2 together. The 16 year old leaped back when he saw his god-like brother come down the stairs. "H-hey man! Shit I'm sorry about the window, but you can just fix it right?"
Ty rolled his eyes and then shot a glance at the broken window, the glass sharps leap back into place and fused together, eliciting a feminine scream from outside.
"Uh...should I ask or just use my power to find out who that is?"
Dustin answered swiftly, "It's Rebecca! You know? Becca from down the street?"
"Oh...oh sure, that girl you like."
"Y-yeah well I kinda told her a little of what you can do..."
Instantly the red headed girl was teleported inside, Ty chucked a bit at her further screams. "Hey, cut it out alright. Calm down a bit before I calm you down..."
The threat seemed to work, Becca bit her lip to keep quiet. A few deep breaths later and she seemed to grasp the situation.
"D-dustin said you..."
"Yeah yeah, I figured I give both of you a mind read while you were freaking out there. I'll do it, but you each owe me one big favor. And Dusty..."
Ty shot a glance at his little brother. "I do have to punish you for the window."
Becca gasped as her body filled with the strange, reality bending power. The slim girl's body filled out on almost every angle, her breasts steadily ballooning out from B cups into the DD range just as her ass, hips, and thighs gain a few inches of fat and muscle. Her button T-shirt and lacy white bra were straining to hold the mounds back. That thick butt giggled as her hip-bone expanded outwards, stretching her uniform skirt out to it's limit. The freckles of her skin are washed away as her skin takes a healthy tan, red hair replaced with sandy blonde. Ty left her green eyes, though, against her wishes.
The reformed girl flushed red, both the cheeks on her face and her exposed rump (her panties having wedged up in the wake of her butt's expansion, the skirt doing nothing to cover the luscious mounds) were painted red with embarrassment. "Ooh...oh god..." she even marveled at the change in her voice, slutty tones washing over every sound she made. "Oh my god...Ty! Th-thank you!" She rushed to hug him and planted a kiss on his cheek.
Dustin looked away, jealousy roiled up inside him as she threw herself at Ty. He was jealous of her affection, but more so jealous of Ty's ability to change the entire world to fit his desires. At least...at least for now Dustin was on Ty's good side, right? But it was then that he remembered Ty's threat of punishment for the window...shit.
Becca cooed and mewed against Ty's built frame, no doubt enjoying the feeling of his enlarged bulge against her belly. "Oh Dustin, we haven't really talked about your punishment yet, but Becca here probably has something to tell you. I think you wanted to be her perfect partner? Someone who could make her cum over and over again?"
The blonde-ified Becca gasped again, this time in horror. "Oh god, Dusty I'm so sorry!"
Dustin heart stopped when she spoke her next words...
