"Brother's face is so cute when he tries to hide it."
Sophia's comment made Alex's face blush even harder. He tried to hide by submerging himself underwater, but Katherine pulled him back to the surface.
"Don't make fun of your brother... Let's get out of the water for a bit to scrub each other's backs now."
A loud water drop could be heard as the four of them got out of the bathtub before sitting down on the small wooden chairs nearby.
As Katherine grabbed a bar of soap and began scrubbing Alex's back, Sophia grabbed another bar and began scrubbing Mary's back.
After scrubbing for a while, the two of them shifted to the front before moving down to their legs.
"Mom, I can do this——"
"Not again. Come on, don't be shy."
Katherine's determination made Alex back down again as he let her clean his crotch area.
With the entire body scrubbed clean, Katherine began rinsing all the soap from Alex's body before handing the showerhead over to Sophia.
"Mom... Can I scrub your body?" Alex asked, feeling a little guilty for having Katherine clean up his body every time.
"Looks like my little boy is all grown up... How could I say no to that?"
Katherine turned around, letting Alex begin scrubbing her back with the bar of soap as she closed her eyes.
"You can put more weight on it. You're scrubbing it too lightly."
Alex began throwing in more elbow grease. Seeing her not comment on anything back, Alex maintained the scrubbing intensity until he finished her back.
"Sophia! Let me scrub you as well!" Mary excitedly pleaded, wanting to copy what Alex was doing for Katherine as Sophia finished rinsing her.
"Fine, but you better scrub hard enough——Ouch, don't scratch your fingernail on me."
"Sorry!"
As the other two just started scrubbing the other person's back, Alex was now at a crossroads.
But after a short silence, he made up his mind.
"Mom, can you turn around? I need to scrub the front, too."
Katherine didn't hesitate as she turned around to face Alex, with both of her hands on the side to let Alex reach every part of her body.
Alex quietly gulped down his saliva as he nervously moved his arm forward to begin scrubbing her chest and arms.
When he moved all the way down from her neck to her breasts, he noticed Katherine's face had seemingly turned a little red.
At first, he thought it was just the steamy room that caused her to blush. But he could hear a quiet, small moan when he moved the soap onto the tip.
Still, she doesn't ask Alex to stop, letting him finish scrubbing her upper body until he reaches down to her belly.
As he took the soap further down, Katherine was getting ready to ask him to stop. However, to her surprise, Alex skipped the crotch completely.
He just moved onto her legs, scrubbing her thighs all the way to her ankles, going as low as the back of her feet before stopping.
"Um, Mom, y-you can do the rest," Alex shyly replied as he handed the soap back to her, as there was only one part left on her body.
"Thank you, sweetie."
With a few fast scrubs around the crotch and the rear, Katherine signaled Alex to begin rinsing her body.
As the showerhead sprayed water onto her body, Alex's head was all over the place, unable to believe what he had just done.
In his mind, the image of the close-up look of her crotch when scrubbing near her thighs was glued into his mind.
The well-trimmed bush that covered her precious part. He wanted to push it open with his finger to reveal her deepest secrets.
"Alex?"
"Sorry!"
Alex quickly snapped back to reality as he resumed carefully rinsing Katherine's body, kicking all of his dirty thoughts out of his mind.

When the four of them were out of the shower, it was already ten o'clock at night.
"Mom, can we sleep together in your room today?" Mary suddenly pleaded just as Katherine was about to bring them back to their room.
After a short consideration, Katherine agreed to it.
"Only for today. Tomorrow, the three of you will have to sleep together in your room."
"Yay!"
As the four of them entered the master bedroom, Mary immediately jumped onto the bed, choosing to be on the far left side of the bed.
Meanwhile, Sophia picked the far right side of the bed, leaving Katherine and Alex sandwiched in the middle.
"Goodnight, everyone." Mary excitedly said out loud as she pulled up the blanket, closing her eyes.
"Goodnight."
As the light automatically turned off, everyone soon fell asleep on the bed except for one person.
This time, however, it wasn't Alex. Instead, it was Katherine who was still thinking about what had happened in the bathroom.
"Alex... He's growing up too fast." Katherine thought to herself as she started to realize something about Alex.
He had always seemed to be shy when he was naked, even when he was a little kid, when the concept of privacy shouldn't have been in his mind.
"Is it because he's ashamed of his body being different?"
Katherine started to develop theories in her head, looking for ways to explain Alex's behavior.
"If he's just a normal boy... Would he still act like this?"
After thinking for a bit, an idea suddenly appeared in her head as she thought back to the amount of time Alex kept staring at her body.
"He's your son, you idiot... He's probably curious about the differences between our bodies. Maybe it's time for me to give them the talk.
All three of them are almost at that age already. And it's not like there's a man in the family who could explain it to Alex either."
With these thoughts in her mind, Katherine soon fell asleep, still unable to decide what to do.
---
As Alex woke up early in the morning, he could feel someone wrapping their arms and legs around him.
But more importantly, his leg cramp was completely gone. No longer was he suffering from the period pain, free from the torture of what a woman had to endure.
"How do women endure this every month?"
Alex thought to himself as he shook Katherine's shoulder to wake her up, finding it a little hard to breathe inside her chest.
"Hm?"
"Mom, can you move your arm a little?"
"Nope, you're sleeping on the bed longer with me...."
Seeing Katherine refuse to let go, Alex didn't bother asking again. He simply moved up a little to breathe again.
Feeling the soft, smooth skin from touching him, Alex soon fell back asleep inside her warm embrace.
But now, Katherine was the one unable to fall asleep again as she felt something hard poking her thighs.
"It's just his morning wood. Just ignore it... He's just growing up."
Just as Katherine was about to get over it, Alex's body suddenly leaned forward, trying to sandwich the pointy thing in between her thighs.
"Alex?"
Katherine gently whispered, but she quickly realized Alex had fallen asleep already, as he had moved purely from his unconscious mind.
With no other way to move without waking him up, Katherine tried to move back a little but accidentally bumped into Mary.
"Whatever... It'll just go away on its own."
After ignoring it for a bit, Katherine's body eventually got used to it and soon fell back asleep.
A few hours later...
Katherine was the first one to wake up as the sun began to rise fully on the horizon, just as the clock hanging on the wall was one hour off from noon.
Despite her attempt not to wake any of them up yet, Alex was awakened by the movement.
As he slowly opened his eyes, he was a little stunned by what he saw.
Katherine stood in front of a full-body mirror, wearing only a pair of black panties, clearly thinking about what to wear.
He knew she never wore bras to sleep, noticing the amount of time she finished showering and didn't wear a bra afterward.
The only thing that always stood in the way was her pajama, the most evil invention in this world that he still couldn't understand.
Back to the mirror, seeing her in secret was making it more exciting than usual, despite having already seen her naked body for the thousandth time.
"I should probably wear the school uniform again... When did my bra become so tight?"
Katherine murmured to herself as Alex watched the mirror's reflection, showing the bra tightly squeezing her breasts a little before clipping on.
Next, she put on a knee-length skirt before grabbing something from the drawer that stunned Alex.
It was a pair of stockings.
"Stocking exists in this world!"
Alex's head started to run wild before calming back down as Katherine suddenly started taking them off.
"I can't wear this... I'm too old for this." Katherine murmured as she put the stocking back inside the drawer.
"You're not too old!"
Alex yelled inside his head as he continued to peep through the blanket, with eyes barely opened.
With the stocking gone, Katherine also removed the knee skirt before changing into a long black skirt that covered all the way to her ankles.
As she left the room and closed the door, Alex finally opened his eyes fully and thought back to what he had just seen.
"That school uniform! It's so cute——"
"Brother... Why are you staring at Mom like that?"
Alex was snapped out of his thoughts as he turned his head to the side, seeing Mary with her eyes wide open, staring right at his face.
"I was just curious about what the school uniform looks like. Ahem, I'm going back to sleep."
Alex quickly pulled the blanket back up, covering himself from his embarrassed face away from Mary.
"Why am I like this? Is it because of my body's hormones? Why am I getting turned on looking at Mom again?"
Unable to answer the question inside his head, he closed his eyes as he tried to fall back asleep.
