Fortunately for Alex, his body wasn't developed enough to react to whatever his mind was thinking about.
"Alex, I know your body is a little different, but you don't have to be ashamed of it, okay?"
Katherine tried to pep talk as she could feel Alex was still a little embarrassed being naked in front of his sister.
However, in reality, he was only embarrassed by being naked in front of her, as Katherine was the only one who was constantly looking at him.
"Yeah, Alex, we really don't mind you being here. You don't need to hide anything."
Sophia added as she moved closer, grabbing onto Alex's left arm before intertwining it with hers.
"Me too! I love bathing with Big Brother!"
Mary suddenly swam directly over to be on top of his lap, making Alex even more nervous.
But after a while, his mind was becoming numb to it, almost as if it had gotten used to being around their naked body.
"Thank you guys..."

After the bath, Katherine stayed behind to pour the water out as the three of them headed inside the wagon.
With the fresh pair of clothes on, the three felt much better as they walked for a bit in the cold air.
"The horses sleep so early... They must be really tired running all day."
Mary murmured as she approached them closer and closer until Sophia pulled her back, preventing her from patting their heads.
"Don't wake them up. We're about to sleep, too."
As the three of them walked inside the tent, Katherine was already waiting for them as she lay inside one of the two blankets.
"Wow... this is a lot more spacious than it looks from the outside..." Alex murmured as he bent down to touch the tent's mysterious wool-like carpet.
"Obviously, I spent a lot of money just on this tent back in the day... Come on, pick a spot."
With Katherine heading over to the tent flaps to zip the tent, the three quickly picked their spot on the soft mattress.
"Dang it, there's no pillow here," Sophia complained as her head fell directly onto the mattress.
"Here, you and Mary share a pillow, okay?"
Katherine pulled out two pillows from the thin air, handing one to Sophia before putting it on below herself.
"Come on, Alex, we can share a pillow. There's no need to be shy."
Without giving Alex any choice, Katherine forcefully dragged him next to her before letting him rest on the same pillow.
"Mom, I'm not a baby anymore," Alex complained as Katherine surrounded him with her soft body.
"You'll always be a baby to me. Okay, it's time to sleep."
The light in the room disappeared, falling into pitch black with only a faint moonlight piercing through the tent ceiling.
A few minutes later...
Alex was still awake, his heart racing as he could feel the same softness on his shoulder earlier in the horse wagon.
Katherine's warm body made him start to have a wild imagination once again.
It was even more severe this time, as her naked body from the shower earlier was still fresh in his memories.
Both fortunate and unfortunate, his body was still unable to release that kind of feeling, besides building frustration inside his head.
"Stop it, Alex. Katherine is your mom... I need to stop thinking about this."
Alex thought to himself as he shook his head, emptying his mind as he thought back to various grammar lessons Katherine had taught to distract himself.
After a while, his mind finally started to feel a hint of drowsiness, and he eventually fell asleep.

The next two days were a repeat of the same thing, except the scenery had changed from plain and forest into rocky mountains.
All three of the kids were in awe, as the mountain was so tall that they couldn't even see the peak.
When Katherine explained to the three that dragons once used the mountain as a nesting place, they were even more in awe.
But after a while, the mountain scenery soon became boring, and the road was filled with rocks and hills, which made it even more unpleasant.
Unfortunately for Alex, the fourth day of the trip brought an unpleasant surprise.
He woke early that morning, the sun barely above the horizon, unaware of what was waiting for him.
Everyone was still sleeping peacefully on the bed, but the leg cramps and wet underwear made it extremely uncomfortable.
"Mom..." Alex whispered as he tried to shake her shoulder gently.
"Hm?"
As Katherine opened her eyes, she was shocked to see Alex's face, which looked pale white and in pain.
"Alex, what's wrong?"
Katherine urgently asked as she immediately got up from the bed, pulling the blanket aside to check.
"I-I think I'm having my period." Alex shyly whispered, not wanting to wake up the other two.
After noticing the blood down below, she immediately carried him out of the tent and into the wagon, then put him down on the wagon bench.
"Looks like you're going to be a fully grown girl now." Katherine joked as she started pulling his blood-stained pants.
"I-I don't want to be a girl."
Alex instantly pushed back, as he had already witnessed Sophia enduring a few days of pain every month for almost a year now.
"Too bad your body doesn't give you the choice... Ahem, Alex, I had been wondering about something..."
"What is it?"
Seeing Katherine's serious face made him a little nervous, but he tried his best to remain calm.
"Why do you want to be a boy so badly?"
The question caught Alex a little off guard as she pulled his pants aside before removing his blood-soaked underwear.
"I just want to be a man... I want to protect you guys like Dad."
Alex quickly made up an excuse, not wanting to admit that the fragmented memories of his previous life had chosen him to be a man.
"Aww, that's so kind. But you being a girl doesn't stop you from protecting us. You don't have to be a boy to protect somebody."
As Katherine began wiping the blood off his labia and thigh with a wet towel, she couldn't help but notice his cute little cock with a pair of small testicles above it.
"I just want to be a boy... Mom, are you done yet?" Alex shyly asked, looking a little embarrassed after noticing what she was staring at.
"Sorry. Ahem, do you remember how to use this, right?"
Katherine quickly pulled out the similar-looking pad that she had once given to Sophia when she had her first period.
"Y-Yeah..."
Alex nodded in agreement as Katherine turned back around to grab a fresh pair of underwear before attaching it.
But unfortunately, his underwear was way too big, leaving a clear gap that could cause leakage on the sides.
"Alex, you don't mind wearing Sophia's panties for a few days, right?"
Alex wanted to say no, but he nodded in agreement as there was no other choice unless he wanted his period blood to leak all over the place.
After Katherine headed back to the wagon to grab a pair of panties, she quickly attached a new pad to them before putting them on for him.
He could immediately feel it was a little too tight around the crotch. It was clear that the panties were not meant for someone with male genitalia.
"It's too tight, isn't it? Just hold on for a few days, okay? Mom will go buy a bigger size one for you."
Alex nodded his head as she gently lifted him up again, carrying him back into the tent as she muttered something.
Right before his eyes, the blood stain on the blanket and the mattress disappeared.
"Okay, let's just continue to sleep until the other two wake up... You can go back to sleep now."
Katherine gently laid Alex back down onto the mattress before covering them with the blanket.
A few hours later...
As everyone finally woke up from the mattress, all four of them immediately headed outside in silence to do their business.
But this time, Katherine went along with Alex, as she was still a little worried about his health despite his protest that he was fine.
After everyone met back up in the middle, Katherine started creating a bucket of water for them to freshen up.
With business taken care of, Katherine packed everything back with a snap of her finger before getting everyone back into the wagon.
"Alex is going to sit in front of me today. You two sit back inside for now, okay?"
Sophia didn't question it after noticing something was a little off about Alex, but Mary was clearly upset by the decision as she questioned why.
"Because your brother had his first period. He's in a little bit of pain right now." Katherine explains, not noticing Alex shaking his head to stop.
"Huh?"
Both of the girls fell into silence for a second as the horse wagon began to move forward.
But loud laughter could be heard right afterward, as they couldn't believe it had finally happened to Alex.
"Wait, you're serious? My brother, out of all people, got his first period?" Sophia asked out loud, not hiding her smile a single bit.
"Shut up! I don't want to hear you guys laugh."
Despite Alex angrily yelling back, the demand was fruitless as they kept on laughing until Katherine stepped in.
"Okay, enough laughing. Your brother is really hurt by it."
"Yeah, I bet he's hurt real bad." Mary joked, hiding her laugh a little this time as she kept on rubbing the salt onto the wound.
"Mary, I hope you know that one day you'll experience the same thing. And I'm going to be the first one to laugh at you——"
"Ahem, Alex, don't take your sister's word seriously. They are just joking with you."
"Hmph!"
