Before you can say anything else Jack decides that he wants a turn with the socks. He rushes home to get some more shoes. He comes back a few minutes with a duffel bag full of them, pulling out a pair of wrestling shoes
"One of my buddies, Robert does wrestling and he left these at my house, I've always wondered what it would be like to be a wrestler" he says
He takes the socks and slides them on, next he slides on Roberts shoes. You watch as the Jacks changes begin, his body drops down until it's about until he's a few inches shorter than you are. His skin darkens to a bronze and his hair changes from curvy to wavy. His face becomes a bit rounder as his body starts putting on about 50 pounds worth of muscle. The last changed take effect until before you stands a rather small but ripped seventeen year old Hispanic boy.
"This feels almost natural it's like I actually am Robert" he says, in a voice deeper than either of your own.
"I Think it's part of the socks"
"Hey, what if we sink into these personas completely?" He asks
"Yeah let's do it"
You both close your eyes and relax your minds as you let your new personas take over. Before, being your father and brother required some effort to be convincing. But now, being Jack and Robert was as effortless as it was being yourselves.
"Hey Robert, what's up?"
"I'm good man how abou you?"
For the next few hours you and Robert catch up and played video games, for a while both of you even forgot that both of you were just pretending to be other people.
Eventually Robert popped the question
"Hey do you think it's time to go back to normal?"
"Sure" you reply
About ten minutes later you both were back in your own bodies, wondering what else to do next.
