He was surprised to see that instead of some adult stranger, a three year old boy walked into the nursery. Leaving the door open behind him the new toddler walked over to stand in front of the mesh wall of the playpen. Like him and Greg he was wearing nothing but a diaper. Being a whole year older the boy's body was more noticably defined with less baby fat, but even with the slight maturity also appear young enough that the disposable garment taped to his behind didn't seem out of place as usually children his age would be wearing pull-ups or some other kind of training pants. Also Bill had to admit he looked positively cute and adorable standing there in just his pampers. Blushing as he realized he was staring he quickly averted his gaze.
"You must be da new guys. My name's Derwick" he greeted with a lisp. "Now I know yoo must have awotta questions..."
Greg automatically interrupted the toddler, "Ya damn wight I got awotta queschins. First off why da hell are we baybees?"
The boy looked at him quizzically, "Beecuz dat's what you agreed to when yoo signed da Toys n Tots contract. Lemme guess ya didn't wead it?"
Both Bill and Greg shook their heads. They thought it was a simple experiment to earn some extra cash for college. Neither one of them expect this to happen. Although Bill was liking the turn of the events, he just didn't wish his roommate didn't have to suffer for his secret fantasy to come true.
"Well dat's unfortunate. Sowwie to tell you this but dese are going to be your new ages for a while" Derrick regretfully admitted.
"How wong we gonna be wike dis?" Bill asked hoping the regression would last a long time.
"Foreva...the serum da compenny have yoo is designed ta be permanent" Derrick revealed to Bill's delight and Greg's horror. The baby boy then waved his hands in a placating fashion, "Now don't werwee da Toys n Toys compenny will take care of everything and all yoo haftar do is test their producks. Doesn't dat sound good?"
Greg who was on the verge of years shouted back, "No, I wanna be an adult!"
Derrick sighed and scratched his head in confusion, "Dat's weird dat you're reacting wike dis, uswally they pick people who want to be dis young wike I did."
"You wanted to be a toddler?" Bill asked in surprise at finding another infantilist like himself.
"Sure did. Eva since high sckool I've wanted to go back to my diapa days. Den the compenny sent me an ad a month after my graduation which I responded to and dey made my dreams come troo" he grinned, showing off his little tiny baby teeth in a wide smile. Bill felt like doing the same as now he had the chance to re-experience his babyhood. And if what Derrick said about the serum was true he'd never have to leave. He'd never have to stop sucking his thumb or using a pacifier. He'd never have to give up drinking from a bottle or sippy cup. And he'd never have to get potty trained and could stay in his diapers until the end of time. All these thoughts made him internally smile at his new future as a baby. Meanwhile Greg had resumed hugging his legs, rocking back and forth as he whimpered.
Feeling bad for dragging his roommate into this, for Bill was partly responsible as the ad for the company had come in the mail just for him. However he convinced Greg to come along and do it with him. Now he was a two year old who had nothing to look forward to but peeing and pooping his pants.
He was about to say something to comfort the other when Derrick start acting funny. The older toddler was shifting lightly from foot to foot with an uncomfortable look on his face.
"Derwick, are yoo okay?" Bill asked out of concern.
"Yeah, I just need ta go potty but wike to hold it in for a bit." After finishing the sentence Derrick's frowny expression morphed into one of concentration. Then not two seconds later a look of relief appeared along with a smug grin. Strangely Bill recalled having seen a similar look like that before and it only took him a couple of seconds to remember where. It was the same look his baby cousin had when he made a number two in his diapers, having caught the moment during their last family visit. Tilting his head to the side he spied that the other's padding was now sitting lower than before. His suspicions were furthered confirmed when less than a minute later a stinky odor reached his nose, the smell obviously coming from Derrick's padded behind.
"Aww dere's nothin' wike dropping a nice big one in your diapa" Derrick openly remarked, looking quite proud about his messy accident.
The three year old then...
