Ty had a good day at school, he got a B on his geometry test, and was walking out of the schools main doors to the bus. Normally Dustin, now Mei, waits for him outside to get back on the bus. "That's strange..." Ty thought to himself. "I wish Mei was here next to me." Ty states.
Next him appears Mei, who immediately slumps to the ground, laying on her side. Her ass is bright red, proof of it being abused all day. Cum seeps from her puffy cunt, which also appears to be glowing from abuse. Ty bends over and rolls her onto her back, revealing her perky tits and exposed midriff.
"Did I make it." Mei croaks, in an apparent fuck-stupor. "I'm afraid not. You didn't even make it half way there." Ty said flatly as he looked at the bold '22' tattooed below her navel. "I'm going to have to punish you extra hard."
. . .
Ty carries Mei up the stairs and into his room, her small body barely a burden on him. Mei had slept the entire bus ride, too exhausted from today's work to remain lucid. Ty had used this time to think of the next stage of her transformation. Resting her on the bed, Ty began to work on her body.
Ty starts on her quivering sex, still dripping cum from today. He wills her vagina to develop new muscles, which allow her to grip and pull cocks deep into her autonomously. The muscles can contract and squeeze semen into her uterus and any cum inside her will be stored and kept virile. This will slowly expand her belly instead of leaking. Concentrating, Ty focuses on her ovaries and blocks them, temporarily sterilizing her.
"Mei is now fully rested and awake." Tyler commands.
Immediately responding, Mei sits up and looks around. Slowly, the realization of what happened today hits her. "What did you do?" Mei cries, her big eyes wide in fear.
"Allow me to demonstrate." Ty replies. Ty wills each of his testicles to expand to the size of a bowling ball, filling to the brim with cum. Ty guides his manhood into her needy red cunt, which opens slightly to greet it.
"My cunt feels like it's tying itself in a knot!" Mei moans, as her pussy greedily sucks Ty's cock deep inside her.
"Oh that's really good." Ty exclaims, as continues to Mei milks his cock. Ty allows his balls to drain slowly into her, the contracting of her cunt drawing his spunk into her.
Over the course of 15 minutes, Ty's balls empty, and return to normal size, having deposited his entire load. Mei, awakening from her self fucking pussy's stupor, is greeted by a massive mound of flesh.
Mei attempts to sit up, but the weight of her new stomach prevents that. Mei cries out and rocks back and forth. Ty looks lustily over Mei's newly filled body. Her drum taut belly is crowned by her navel, which has been turned out by the swelling. Her heavy, cum filled belly makes her appear to be very pregnant.
Ty helps Mei to her feet, which is difficult due weight of her belly. Her tiny frame struggles to support the approximately two liters of cum stored inside her. "It's so heavy. How do I get it out?" She moans as she she unsuccessfully tries to wrap her arms around her belly.
"I might let you leak if you get too big, but for now it's permanent."
