Johnny and Dukey moved through the house as fast as they could, even though Johnny was constantly stumbling due to his new huge feet.
"Ouch! My toes hurt!" Johnny yelled. "How can dad bear with their!"
"It's not just your dad." Dukey said. "All men grow their feet when they get older. It's a common thing!"
"I know but that's not what I meant." Johnny replied.
When they arrived to Susan and Mary's lab they looked them working on a big computer.
"Do you have any progress about what happened with dad and Johnny?" Susan asked.
"Not yet." Mary replied. "It doesn't make sense. The device is working properly and there aren't errors registered on the pc."
"Susan, Mary!" Dukey shouted. "We have a problem with Johnny!"
"Not now, Dukey." Susan said without apart her sight from the computer. "We're busy."
"Uhm... Hello?" Johnny said and his deep voice took her sisters attention who turned to look at him.
"Woah!" Susan said. "Is that you, Johnny?"
Johnny just smiled awkwardly.
"It looks like the device didn't change his mind with dad but made him older. Do you know if dad was affected in some way?" Mary asked.
"I have seen him and he looks normal." Dukey said. "But Johnny woke up like this and it looks that he is still changing!"
"What do you mean with that?" Mary said.
"Well..." Dukey said a little embarrassed. "His male thingy... It's swollen."
Susan and Mary didn't said anything but their faces turned red for a moment. For some reason Johnny turned red too. Talking about it with Dukey was ok, but they were his sisters. Girls... women.
"Ahem... I think we should take some samples and make some observations." Susan said. "I'll take care of Johnny. Mary, go with Dukey and check if dad has signs of secondary effects."
Mary and Dukey nodded and left the lab almost immediately.
"Ok, and what do I do?" Johnny asked his sister.
"Take off your clothes." Susan said. "I'll do some test."
Johnny began to take off his clothes. Susan can't avoid looking at her brother new frame. She thought he looked so mature and sexy with that body hair that he didn't have before. But what took almost all her attention was the huge bulge barely retained inside his briefs which he didn't took off.
"Ok. I'm ready." Johnny said as he instinctively covered his bulge behind his now big hands. His sisters had seen him in underwear before but for some reason he felt more exposed now.
"Ok... Johnny." Susan said as she tried to focus on the pc. "Please go inside this cabin. I'll begin the test."
