Upstairs, Dustin had COD 25 blaring as loud as he could through a set of surround sound speakers mounted on the wall of his sweaty testosterone flavored room.
Ty stood at the edge of the doorway, listening to Dustin talk shit over a mic to other people he'd never meet in real life, and took a moment to reflect. Mark was now so small he was lost to human sight, June was shrunk and imprisoned in a bug jar, and here was Dustin lying belly down on his bed.
Ty recalled the day so far, the discovery of his abilities, Dustin's regressing, accidentally almost destroying the universe, the bizarre and satisfying sex and play with Eileen, and now the last few moments. He wondered if this is how God felt.
No matter, he shrugged.
He walked in front of Dustin, sizing him up, and smiled. He was totally invisible as if he didn't even exist. He could do whatever he wanted to Dustin, who had made his life so incredibly terrible for so long.
He suddenly knew what he was going to do.
He looked at Dustin, eagerly engrossed in electronic killing, and willed him to turn female. Just a little bit. Just a tiny little bit.
Dustin suddenly tingled all over and paused, still holding the controller, as his muscle tone shrank just a teensy little bit. He looked over himself, confused, and when back to his game, not realizing he had just lost his recent gains at the gym.
Ty waited for a while, thoroughly enjoying the slight difference, and gave Dustin another pulse of feminization. Dustin paused again, racked with tingling, and this time he lost significant bulk, his athletic muscle shrinking down all over. He was still a little buff, but his shoulders, chest, and biceps had lost enough that his shirt had gotten loose. His pants too, hung on a slimmer frame.
He heard Dustin tell his buddies he had to go piss and watched as Dustin sat up on the bed and realized something was wrong. He looked over his arms and especially his once prominant pecs and his jaw dropped. Perhaps Dustin wasn't that stupid after all, Ty laughed.
Dustin rose from the bed in disbelief and panic, and ran to the bathroom next door to Ty's room. He quickly pulled his shirt off and gasped as he saw that years of weight training and workouts had been erased.
"What the fuck?!" Dustin yelled, running his hands over smaller muscles. He had shrunk! Deflated! Oddly, his chest hair had lessened too.
Ty blushed, standing next to Dustin as he stared in the bathroom mirror and dropped his pants. His legs too, had lessened. The same thing was happening with the hair down below, too. Dustin gulped, seeing his package looked smaller too, and dropped his boxers.
Ty gaped in shock, he had seen Dustin walk by naked almost every morning, and his cock had been a considerable size, but now it was much much smaller!
"My..." Dustin trailed off, and to Ty's astonishment he quickly shut and locked the bathroom door, growing an erection that was substantially less than before.
"Oh my God..." Dustin stared in the mirror, stroking an at most five inch penis. "It's happening... it's finally happening to me..."
Ty blinked in shock and realized what was happening here. He gave Dustin another pulse of feminization and watched in startled delight as Dustin moaned with the tingling, even as his muscles slimmed further, body hair faded, and his frame began to dwindle. Dustin gripped a shrinking penis, now three inches long fully hard, and panted frantically, staring at a softer girly vision of himself in the mirror. "More!" He said in a higher pitched voice. "Please! More!"
Ty obliged happily, shifting Dustin further into womanhood. He grabbed the countertop with shrinking hands and cried out as the last hints of his manly body faded and he began to shrink. When Dustin opened his eyes, he was halfway between boy and girl, his body strange and adrogynous, flat without definition, and his face softened into the start of a woman.
It was his dick that was most incredible though. It had dwindled flat to his hairless groin and barely poked out above balls that had gone completely smooth. Dustin rubbed his crotch excitedly and blushed harder, touching his chest and newly sensitive nipples with pure erotic bliss.
Now Ty gave him the rest of it. Dustin squeeled and grabbed his/her groin as the slit of his former cock began to open up into the distinct slash of a pussy. His other hand busily rubbed his chest, encouraging it to grow, as he shrank shorter, smaller, and his body began to properly feminize.
Ty watched in amazement as Dustin's hair grew long, his face grew sleeker, and before long he was an attractive young woman with growing breasts and curves.
Dustin fell to the floor, moaning as he rubbed his new clit, and fingered his pussy as it grew deeper and deeper by the second. Ty urged Dustin's breasts to grow big and firm, and this seemed to drive to the developing girl into a frenzy as her waist cinched and her hips grew.
Before long, a beautiful young blonde now sat on the bathroom floor masturbating with wet slurps of her new pussy, small, cute, and busty. Ty watched as Dustin came with her first female orgasm and let out a raptured cry of release.
Slowly, Dustin panted to breath and stood, staring at herself in the mirror and offering a pouty pose, before breaking out into laughter and hugging herself tight.
"Fuck you, dad!" Dustin said, throwing her head back. "I hated football anyway!"
