Crossover Anime: A Dimensional Journey Starting with Frilian

"Mengmeng, what are you saying!" Nana glared at Mengmeng, annoyed.

"That's right, my brother-in-law is family with us, what's there to care about?"

"Brother-in-law isn't sister! Let's hurry up and pick out some underwear!" Nana didn't want to miss the chance to turn her back on Shichen, so she quickly pulled Mengmeng along and started picking out underwear.

This lingerie store is great; they're very thoughtful. Every style is available in all sizes, so if you're not confident, you don't need to worry about needing help from the staff.

As girls, Nana and Mengmeng are quite interested in underwear, and even more interested in underwear from this planet.

The two began to carefully select their favorite styles.

"Chen, I also want to buy a bra." Lala looked at her two Mengmengs and couldn't help but say to Shi Chen.

"You want to buy underwear too? Really?" Shi Chen looked at her incredulously.

"Ugh~ Chen, what do you mean?" Lala playfully slapped him.

"Isn't this surprising? You clearly don't like wearing underwear." Shi Chen smiled.

At home, Lala would definitely sneak off her underwear; she didn't like it and preferred to be naked.

Wearing certain clothes at school is strictly required by the time of day.

"I don't like wearing it... but Chen, you like it~" Lala whispered.

"Hmm? For me?" Shi Chen couldn't help but chuckle.

"Then what else? Pick one out for me."

"It's possible, but I can't wear it myself."

"Huh? It really is in the store..."

"It's alright, I'll set up a barrier later," Shi Chen said softly, his tone full of temptation.

"Hmm..." Lala hesitated for a moment, then finally agreed.

Just then, Nana and Mengmeng also picked out their underwear and were about to try it on.

"Brother-in-law, sister, please wait for us a moment," Mengmeng said.

Nana went straight to the changing room, and she walked quite quickly.

"it is good."

Once the two entered the changing room, Shichen began selecting underwear for Lala.

With Lala's slender yet curvy figure and fair, rosy skin, any underwear is just an accessory, serving only as a backdrop.

So Shichen chose a very ordinary set of underwear—white with lace trim.

It's a bit plain and simple, but it should suit Lala very well.

Ignoring the gazes of the shop assistants in the distance, the two then walked together toward the changing room.

Shi Chen found a changing room a little distance away from Mengmeng and the others, and went in with Lala.

The space inside is quite large, enough for two people to move around freely; I wonder if it was prepared for certain individuals.

After checking, Shi Chen found no surveillance cameras or surveillance equipment, so he set up a barrier and began helping Lala change her clothes.

Lala was wearing her school uniform, and Shichen, who was already familiar with her, helped her take it off.

Lala pursed her lips, her pretty face flushed, her heart pounding, but she still held back, letting time dictate her actions.

She turned her back to him, raised her hands and feet, and finally took off all her gear. The changing room was immediately enveloped in a layer of pink light.

Lala truly lives up to her alien status; her skin is incredibly delicate, fair with a rosy glow, and its radiance is so captivating and mesmerizing.

Shichen put her equipment aside and gently hugged her from behind.

“Chen…?” Lala turned to look at him.

"Don't rush to change. Let me check if you've changed at all," Shi Chen said.

"Variety?"

"What if it develops?"

"How could it be so fast... um~" Lala's heart tightened before she could finish her sentence.

At the appointed time, she began to move her five fingers to check her development.

Lala couldn't stand up for more than a few seconds.

Shi Chen continued with his actions, sat on the stool, put Lala on his lap, and covered her mouth with a kiss.

Inside the changing room, he mumbled incoherently, but it was completely inaudible outside.

......

After changing into her underwear, Mengmeng felt it fit perfectly and left the changing room.

"Brother-in-law... um?"

She looked around but couldn't find the time, nor could her sister.

The two of them probably wouldn't have abandoned them, but just in case, she went to ask the shop assistant.

The shop assistant simply told her the time and Lala's location.

So, filled with curiosity, Mengmeng cautiously approached the door of the changing room where Shichen and Lala were.

There was no sound from outside the door, but Mengmeng didn't think nothing was happening inside.

Is it really necessary for us to go in together if we're not going to do something?

It must be the older sister who is holding back from making a sound.

Mengmeng was itching to know what was going on inside, but she couldn't just go in directly.

There was nothing to see outside.

She could only get close to the door, press her ear against it, and secretly listen to what was happening inside.

But we still didn't hear anything.

This is unreasonable.

No matter what, it's impossible for there to be absolutely no sound.

"Mengmeng, what are you doing?" Nana had finished trying on the clothes and noticed Mengmeng's strange behavior, so she walked over in confusion.

"Shh~" Mengmeng immediately reminded her to be quiet.

"What are you doing?" Nana asked, puzzled.

"My brother-in-law and sister are inside."

"Oh, they're inside... Huh?!" Nana realized what was happening, and her pretty face instantly turned red.

"Shhh, keep your voice down."

"Um... are my sister and him really inside?" Nana asked again, still in disbelief.

"real!"

"Then they're inside..."

"What do you think?"

"This is out in the open... Is that guy really that impatient?"

"After all, it's a lingerie store~"

"That's not possible..."

"This shows that my brother-in-law and sister are very much in love."

"...Then what are you doing here? You're not eavesdropping, are you?"

"I want to too... but I can't hear anything," Mengmeng said regretfully.

"Can't hear anything? Wait, what did you say? You really want to hear it? Are you serious?"

"Curious~"

"..."

Chapter 557 Mengmeng's Night Visit

"Mengmeng, what's wrong with you?" Nana grabbed Mengmeng's shoulders, staring intently into her eyes with a serious expression.

From the moment she arrived on this planet, she noticed that something was off about her twin sister.

Especially in terms of time of day.

It's like she's particularly curious about him!

No matter what it is!

I was particularly curious about the private matters between him and his sister.

Is this something a younger sister should be curious about?

Even if it's out of teenage curiosity, you shouldn't ask so directly!

Moreover, her attitude toward the time was clearly wrong!

We were completely unguarded with him, treating him with complete ease, as if... how could this be possible!

"Huh? What's wrong with me?" Mengmeng tilted her head, looking at Nana with confusion.

"You...you are...?" Nana hesitated, unable to finish her sentence.

"What am I?"

"...Never mind, it's nothing." Nana shook her head and gave up asking.

She thought about it and realized it was probably impossible. After all, that guy was her brother-in-law, and as his sister, she shouldn't have done that.

"Nana, you're so strange."

"Hmph, you're the one who's strange... Go away, what are you doing here?"

"Hey~ Aren't you curious? Don't you want to know how your sister is treated? Don't you want to know your sister's expression? Don't you want to know what your brother-in-law will do?"
