“Sure I guess we could try that.” You say a little less than enthusiastically.
“Perfect.” Your dad turned to the still open bathroom door.
“Hey Tim get over here, you’re not gonna believe this!” He yelled.
“Dad! At least let me change back first!”
“What for? You’re already in my body like I’m planning.”
Tim walked into the room.
“What is it dad?” Tim looked past your father and saw you in your torn clothes.
“Oh hey dad.” he was about to go back to talking to your real dad when he realized he just addressed him, twice.
“Wha wha wha who?????” Tim stuttered in confusion.
“Calm down son, I’m your real father. This handsome devil before you is actually your older brother.”
Dad then explained to Tim everything you told him about the socks.
“Awesome! Lemme go first!”
“Not so fast Timmothy. It was my idea, so your old man will be going first. Well.. “old man” for now.” He looked at you and playfully winked.
“Pass me your sneakers Tim.” Tim excitedly removed his shoes and handed them over to your dad. You did the same with the magic socks.
“Hmm so how am I going to fit into these?” He held out the child size pair of shoes.
“You can just try to fit some toes in.” You suggested.
Dad complied. You and Tim then stared at him until the changes began.
A few moments passed as you continued to wait in intense silence for the magic to happen. Maybe the socks had a cooldown period?
“Hey, I think I’m starting to feel something!”
Your father then let out a massive burp to Tim’s amusement.
Just then you noticed his gut start to recede a bit.
“Hey dad it’s starting!” You exclaimed.
His muscles quickly began to deflate like a balloon as the socks worked their strange magic on him. The shadow of your father’s (that he often shaved) faded away. His large feet even began to shrink and fit into Tim’s shoes! Your dad watched his strong hands as they lighted and smoothed with his regression. Pretty soon there was an exactly copy of Tim swimming in a grown man’s clothes.
“Dad you look just like me!!!” Tim said, positively jumping with excitement.
“Aw childhood, how I’ve missed you so.” Your dad lamented.
“Well, I better get out of these blanket-like clothes.” To your surprise, Dad began to strip right in front of you.
“Ew gross dad, come on. I don’t need to see that.”
You dad triumphantly puffed out his small chest. “Son we’re doing some real bonding here, no need to be embarrassed of your brother’s male form. Right Tim?” Tim happily nodded. They both definitely have no shame you thought to yourself.
“Okay Tim, you’re up!”
Now was the moment you were kinda dreading. You’re little brother Tim being in your body.
Your dad handed Tim the socks and grabbed the shoes you ditched in the bathroom before you transformed.
“You better undress a bit before the change son, wouldn’t want you tearing your clothes like “dad” here.” It was weird hearing Tim’s high pitched voice speak with your dad’s mannerisms.
“Ok dad, I mean me, uh I mean “Tim.” Tim struggled to reply.
He took off his shirt and shorts but thankfully left his underwear on.
He rushed to put on the socks and stuck his tiny feet into your shoes.
Oddly enough, Tim’s change seemed more noticeable right at the start. His feet quickly grew into your old shoes as his skinny body expanded. His smooth legs sprouted hair as well as his armpits. Not nearly as much you when you transformed into you father but still significant for Tim.
“Oh man this is feEls sO GOoD!” Tim’s voice cracked as he entered puberty.
His small underwear strained as it began to fill up with your old penis. His skinny figure began to gain some slight muscle mass. Soon the change was complete.
“Dad look at me! I’m a teenager now!”
“They grow up so fast.” Your father joked.
Tim pulled at the waistband of his now small underwear. “Check it out I have hair down there now!”
“Just wait until you make it harder and take off those tighty-whities before you tear them.” You give your dad a serious look but he doesn’t seem to notice.
It felt so embarrassing watching your 15 year old body being paraded around by Tim. You were just beginning to start working out too.
“Hey Tim, try this!” You dad then began gyrate his nude childish hips.
Tim copied you father. “Like this dad?”
You couldn’t believe it, he was making him helicopter your dick!
“Alright alright, you two nudists have had your fun. Can we all please agree to just put some clothes on now?” You sternly ask in your father’s booming voice.
“Jeez lighten up.” Teenage Tim whined in as you.
“No no, our father’s right. We better get used to our new roles for the time being.” Dad said.
