"Um, Riley."
"What?" Riley said as he explored his new body.
"I feel terrible ashamed of what I did with you." Nick shyly said.
"It's ok, we weren't in control of our bodies. It's not like we're gay or so."
"That's right. It was just a pre-programmed part, please don't tell my girlfriend about it." Nick begged.
"I won't and even if I do, she won't believe it." Riley said. "I still can't believe we're the Carlson twins!"
"Who?"
"It doesn't matter." Riley said. "Well, according to the TV, we're going to be in these bodies for 24 hours."
"Look!!" Nick shouted as he pointed at the TV screen. "There's a chronometer on the screen! We have 20 hours and a half left. Wait a minute... what's a chronometer?"
"That means we have until tomorrow sunset to turn back to our original bodies. What do you want to do meanwhile?"
"I don't know. I've never been an adult before." Nick said.
"What do you think if we put on some clothes and explore the hotel?" Riley said.
Nick looked down at his body and noticed that he was naked. In other circumstances he would be completely embarrassed, but after making out with his twin, Riley, he didn't feel ashamed of being seeing by him.
"There's a problem." Riley said as he looked in his bag. "None of my clothes fits me."
"I think I'm on the same." Nick replied. "I brought kids clothes no grown-up clothes."
"Maybe there's something we can use in these closets." Riley said as he opened them. "Look, there are different suits." Nick jumped out of the bed and went to look.
"Riley, those aren't suit. They're costumes!" Nick said. "Policeman, caveman, sailor... Look, there's even animal costumes in these corner!"
"So, do you want to try one of them?" Riley smirked at Nick.
"No, after seeing what the TV had done to us, I'm sure those costumes will change us again." Nick replied.
"Come on! Aren't you curious?" Riley said as he started to dress the cop uniform. "See, there's nothing strange about the- ohoohooah!"
When Riley finished dressing his muscles suddenly bulked up, his back broadened and a full goatee appeared on his face. He got a lot of police knowledge including their authoritative behavior.
"Woah! I didn't expect that happened." Riley said in a way more deeper voice as he looked at his huge biceps. "Now, it's you turn, kid."
"I told you I won't." Nick said as he turned around. "I'm going to take a shower."
However, cop Riley don't accept a No as answer and when his friend wasn't seeing him, he took a baby costume and suddenly jumped on him.
"Wait!! What are you doing?!!!" Nick struggled with Riley as he tried to avoid the diaper that he was putting on his crotch. However, with Riley's new skills he dominated his friend and managed to close the diaper around Nick's waist. Nick immediately stood up and tried to take it out but he suddenly stopped when he started to change.
"Oohoooh!!" Nick moaned as he felt his dick shrinking inside the diaper until he has a tiny baby dick. Then, his newly got body hair vanished until he had soft baby skin and finally he lost strength in his legs and fell on his butt. Inside his mind, he can still think like himself but outside he could only behave like a baby, babbling and barely speaking like one.
"That's better." Riley said. "I like when people cooperate." Nick didn't say a thing, he just smiled and clapped. "But I won't keep you as a baby all the time. I don't wanna change diapers! So, let's see if I found a better costume in the closet. Which one will I put on you?"
