"How is this change going to work Jesse?" Nick asked as Jesse smirked. "Well the more we have to change our forms, the faster the change will be, since it has to compensate for time I guess. I don't think anything will happen today though, but tomorrow, maybe something." Jesse said with a shrug as Nick nodded. "Well... good night then." Nick said as he went in his room. "Night Nick." Jesse said, going back in his room and laying on the bed and falling asleep.
The next day both boys woke up rather late, since it was a Sunday. Nick slowly got out of bed as he walked out of his room, Jesse already standing outside his leaning against the wall. "Anything change yet Jesse?" Nick asked with a yawn as Jesse nodded slightly. "Wait what?" Nick said noticing the nod as Jesse slowly started to pull his pants down. Nick blinked as he looked at Jesse's crotch. His dick had shrunken immensely, to the point where it was practically a nub and his balls were tiny. "Did you check yourself?" Jesse asked as Nick gulped before slowly pulling his own pants down and allowing Jesse a look.
"I think we match right now." Jesse said quietly as Nick gasped, grasping as his tiny dick with a whimper as Jesse shook his head. "Whatever we're changing into, it's going to be a drastic change." Jesse said quietly as Nick nodded. It was at that moment Jesse's eyes went wide as Nick felt his tiny dick quiver.
Almost in sync the remains of their dicks and balls shot up into their bodies. Nick grasping at the currently bare skin as Jesse shook his head. "Nick calm down." Jesse said as Nick slowly calmed down. "This is a major change Jesse. I mean we're both becoming chicks!" Nick said in a panic as Jesse shrugged. "So, no one with notice." Jesse said as Nick sighed. "That's not the point Jesse." Nick said quietly as he slowly walked away to get something to eat.
Jesse slowly looked down at his own bare crotch, touching the bare skin and feeling nothing but his fingers against it as he sighed. "Looks like we're changing at the same rate, so we might be similar, at least in some respects." Jesse whispered as he walked towards the kitchen herself, still without his pants.
As Nick and Jesse slowly ate their breakfast, neither noticed as a few more minor changes happened. Their hips had extended outwards slightly, and their nipples had started to become more puffy. Neither was a girl yet, but it would change soon enough. The two were silent through out most of their day as they slowly changed. During the second day they would become more feminine, before becoming full girls on the third. By the time both of them went to bed, Nick and Jesse had small A-cup breasts, longer hair and slightly changed faces, appearing more androgynous.
When Nick awoke he yawned slightly as he go up and looked in the mirror. During the night his chest had expanded slightly to a B cup set, leaving him to touch his breasts lightly as he felt down in his pants, his crotch still bare, but now more sensitive as he blushed slightly from the touch.
Walking out of his room Jesse was already at the table, eating his cereal and looking similar to Nick, both of them feminine looking boys at the moment, but they could pass as girls easily. Neither spoke as they continued going about their day, changing more and more until one final dam broke while Jesse had been in the shower and Nick had been trying to use the toilet.
Both of them had their vagina's open at the same time, both feeling immense pleasure at the feeling as Jesse sat down in the shower and started fingering herself, her D cup breasts heavy yet perky on her chest as Nick blushed from the feeling her vagina now gave her, her own D cup slightly distracting as both girls remained silent to each other, until Nick felt and Jesse started pleasuring herself in the shower again.
That night both girls had gone to sleep fully female. Both were sporting DD cup breasts and long hair among other changes that made them female. Their wardrobe along with reality had already shifted for them thankful as the first changes of the inhuman kind began to appear while they slept, where the two girls started to diverge.
Jesse's ass crack had sealed shut as it puckered slightly, her ass swelling slightly as she slept as small purple hairs appeared on her lower body, not enough to be noticeable, but they were there. Nick however had a small clump of yellow hairs form above her butt, starting to form a tail as her hair started to turn yellow and small brown hairs appeared on her legs.
The next day when both girls awoke they had instantly started checking themselves for changes. Nick slowly turning around and feeling the start of her new tail as she held a strand of his changing hair. "Just what am I becoming?" Nick whispered to herself as in her room, Jesse was examining her own change.
Jesse had her hands on her slightly swelled ass as she looked at her now puckered and pointed asshole with a grin. She felt a small amount of pressure near her butt that she knew she could force at anytime. It wasn't much right now but it would grow, the start of her spider silk.
"Jesse?" Nick asked as she knocked on the door, Jesse opening it with a smile, still naked as Nick averted her eyes. "We both have the same stuff Nick, just come in and don't be shy." Jesse said, leading her into her room before touching Nick's tail. "Growing a tail huh?" Jesse asked as Nick nodded. "I got my own surprise." Jesse said as she turned around, showing Nick her swelling and puckered ass. "Really Jesse?" Nick asked as she averted her eyes again. "Open your dam eyes and watch." Jesse said to him as Nick slowly peeked at Jesse's ass, Jesse grunting as she pushed.
Nick's mouth dropped wide open as a small strand of white forced itself out of Jesse's puckered asshole, Jesse grabbing it before holding the strand in front of Nick. "Spider silk. I'm becoming a drider, part human, part spider." Jesse said with a smile as Nick crossed her arms over her chest. "And what am I?" She asked as Jesse smirked. "Probably a centaur, look on the bright side, we'll be part animal." Jesse said with a smile as Nick groaned and walked out of Jesse's room as she continued to play with herself and her new butthole.
The day went on as the changes progressed, hair becoming more visible on both Nick and Jesse as they avoided each other. Jesse's butt had swelled even larger as Nick's tail grew, becoming full length by the night when they spoke to each other again.
Nick frowned as she looked at Jesse's new abdomen. She had a large bulge behind her with bits of purple hair covering it as Jesse smiled at Nick, looking at her now brown and hair covered legs and her full length tail that was swishing about behind her angrily. "Darn it Jesse, we're freaks." Nick commented as she held her nose. "Not in this reality. Stuff like this is common Nick." Jesse said as she made mention of the change she had caused to reality. "Great..." Nick huffed as she stomped off to her room, Jesse going to her own to sleep as well. For tomorrow would just be more changes.
