The dead skins and dirt on the top layer of the water started evaporating along with the steam until the water was back to being warm.
As the four of them emerged from the water, they were a bit stunned by how they looked.
Katherine's skin was perfectly smooth, with the wrinkles gone and her face giving off a warm gesture.
Her voluptuous body and towering height added to an overwhelming motherly feeling to anyone who met her.
Meanwhile, Sophia looked like a perfectly crafted doll without any flaws, her small, petite body being the only outlier.
But there was no question that it was only a matter of time before she caught up, as she looked just like a younger version of Katherine.
Still, Sophia's facial details were sharply contrasted, as she was much more energetic and sharp than Katherine's warm and soft look.
Next, Mary went through the least amount of change compared to the other two.
She was just as cute as ever, with her body barely showing any signs of growth yet besides a small little bump on her chest.
The only significant change was her skin, which looked even more clear than before.
At the same time, her hair seemed to be longer than before. At least, that is what the three felt like from looking at her.
Lastly, Alex was the last one they turned their attention to.
His face was still the same as before, with a sharp yet feminine look that could easily pass off as a girl.
It was much closer to Sophia, albeit without the energetic part, as he looked more calm and collected.
Alex's body, however, went through a drastic change that shocked all three of the girls.
The muscle that had been developing had mostly vanished, with the body appearing much more feminine than before.
His body was becoming much more like Sophia's, being a petite version of Katherine.
Yet, there was one outlier that made his body look like the opposite of being feminine.
"A-Alex, your penis..." Katherine pointed out as the other two still looked a little stunned.
As he looked down, he was shocked to find his cock had grown much bigger than before.
It had gone from being an erect, small little pinky all the way to almost twice his index finger.
Not to mention, he still had plenty of time to grow, as his body had yet to finish maturing.
"I..."
"Ahem, let's get out of the shower now."
All three of the kids quickly agreed as they followed Katherine out of the bathtub and back into the tent.
As everyone put on a new pair of clothes, Alex was once again met with the dilemma he now faced.
In the end, he still chose to put them on, with the legging and the skirt together, before putting on a button shirt.
"Alex looks like a girl so much now..." Mary murmured, with Sophia nodding in agreement.
"Stop making fun of your brother. You three pack everything up. We're going to head back early."
Katherine intervened, with Alex looking over to Katherine with gratitude as his face blushes red.
"Thanks..."

The next day...
When the three of them were woken up, Katherine was in their room, flipping their blanket over.
"Stop sleeping, you piggies. It's already eight o'clock." Katherine yelled as all three of them slowly sat up from the bed.
"Isn't it only Sunday?" Alex yawned.
"You wish. We somehow slept through an entire day after the dungeon already.
Get up. You three need to get to school right now——"
"What? Didn't we go to bed on a Saturday?" Sophia questioned as she looked a little confused as well.
"No, you guys went to bed on a Sunday night. We slept for an entire day in the tent on Friday and then Saturday after we opened the chest.
When we took the shower, it was already Sunday night. Now get up and go eat breakfast——"
"But we have a three-day weekend, no?"
Mary's point suddenly made Katherine freeze for a second before she facepalmed herself.
"Oh, right... Um, get up and eat the breakfast anyway. You guys had been sleeping too much."
As Katherine left the room to wait in the kitchen, the three of them went to the restroom to freshen up.
After cleaning themselves, the three of them finally headed over to the kitchen to eat breakfast.
"What do you guys want to do today?" Katherine asked as the three of them began eating the noodles.
"Arena."
Seeing the same response from them, Katherine didn't bother to stop them as they drank the milk before finishing up the noodles.
"Bye, Mom!"
"Bye! Don't be so late, okay!"
With the house all to herself, Katherine headed back inside, passing the living room and into the hallway.
As she stood in front of the two-bedroom of the house, she started to consider modifying it.
It was only a matter of time before they wanted their room for some privacy, even though they said they didn't care about it.
She could notice a small awkwardness increasingly common between the two girls and Alex every time they took a shower together.
Especially after what she saw in the morning when she woke them up, with the blanket forming a small little tent.
It was clear Alex could not sleep with the other two together any longer, as her rational mind had finally realized the situation.
"I should just give each of them a room. If I make this room a little smaller, then cut the storage room in half for space..."
As Katherine began calculating, she was able to fit two brand-new rooms that were still linked to the bedroom hallway.
To make space for it, she simply had to cut the tail of the storage room into a rectangle rather than an L shape.
