I Came to a World Where the Concept of Chastity is Reversed, so I Tried to Change my Job to a Playboy, but the Interference is Intense. Please Help me.

Chapter 19: “But I’m Not Mentally Prepared for That…”

I entered the bathroom with Umi, my heart pounding.

I braced myself, thinking she might do something else after that, but nothing much happened.

We relaxed side by side in the tub.

I was the first one out of the bathroom, starting to dry my hair with a dryer.

Umi, wearing a cute pink pajama set, emerged from the bathroom later and headed toward the kitchen.

“Onii-chan, do you want something to drink?”

“Yeah.”

“How about some tea?”

“Sure,”

Umi fetched two glasses from the kitchen and poured cold tea from the fridge. She brought them over to me.

“Thanks,”

“Onii-chan, your hair’s still damp!”

“That’s fine for guys with short hair,”

“It’s not good like that,”

“Thanks… But I’m not very good at this,”

“I’ll show you how it’s done. Watch carefully,”

“Alright, I’ll leave it to you,” I decided, thinking it would be beneficial for me to learn how to dry a girl’s hair.

“Leave it to me!” she replied cheerfully.

Once my hair was dry, Umi handed me the dryer and instructed me on the proper way to dry my hair.

“So this is how it’s done, huh?”

“Yup! See you tomorrow!”

“So you’re only going to dry my hair?”

“I’ll help you with your bath too!”

“Won’t my reasoning crumble if you do that?”

“Wouldn’t that be good?”

“Are you a demon?”

“I’m your sister,” she giggled.

“Umm… I think it’s too soon to cross that line, don’t you think?”

“I don’t want to get pregnant so early too, so I’ll hold off on that line for now,” Umi assured me.

“That’s responsible of you.”

“We’re not doing the real thing yet.”

“What about everything else, then…?”

“Why not do it since we’re going to eventually?”

“So, you’re planning on starting seed provision once we’re in high school?”

“Yeah, more or less.”

“By yourself?”

“Hmm…”

“What do you use for your… umm… ‘snack’ then?”

“I let the beast loose in my mind.”

“If you keep the beast confined in your mind, it’ll be miserable.”

“You want me to let it out…?”

“Why don’t you let it roam free at my place and Shigure’s? We’ll take good care of it!”

“That’d lead to us crossing the line immediately!”

“I don’t want to get pregnant yet, so as long as you wear a condom, it’s fine!”

“…”

“Onii-chan, give up already. I know you treasure us, and we’ll eventually do the real thing anyway, so what’s the big deal?”

“But… ever since we came to my room, you’ve been handling me rather casually!”

“That’s because you keep stalling and making excuses! You’re such a wuss! How did you even have a girlfriend before?”

Umi’s psychological attack dealt critical damage to my heart.

I fell to the ground, but Umi wasn’t done yet. She sat next to me, continuing her relentless verbal assault.

“You know, while the previous Onii-chan was a hikikomori, I read many shoujo manga to think about men. There was a protagonist just like you, and I was so irritated because I kept thinking, ‘When is he going to make a move?'”

Umi, please! My HP is at zero!

“I know you’re embarrassed, but since a lady’s inviting you, you should respond appropriately, understand?”

“Y-yes…”

“So, let’s go?”

“Go where?”

“To my room, right? We’re sleeping in my room.”

“Ah, yeah… OK.”

I stood up with Umi’s help and headed to her room. As we entered, Umi wouldn’t let me get ready for bed.

“Come on, Onii-chan, it’s time for our daily routine.”

“Daily routine?”

“Sit on the bed, Onii-chan.”

I sat on the bed as instructed. Then, Umi casually sat on my lap, pressing her back against my chest. The scent of her freshly washed body was strong, and I couldn’t help but notice.

“Is that OK with you, Onii-chan?”

“What’s about to happen?”

“You remember when we played the King’s Game and I said you used to massage my chest, right?”

“Yeah, I remember that.”

“So, are you going to do it now?”

“Huh? You’re not serious, are you?”

“And why not?”

“…”

“You’re really going to do it then?”

“Which would you prefer in a wife, big breasts or small breasts?”

” Bigger breasts, for sure.”

“So, you know what to do, right?”

With that, Umi discarded her pajama top. Her full breasts, emphasized by a gray sports bra, were more than enough to tantalize the beast within me that had been starved for too long.

Realizing there was no escape, I began obediently massaging Umi’s chest.

“Finally, you’re touching them! How do you like my breasts?”

“They’re, they’re truly wonderful!”

“Good! But if you’re going to do it, then…”

Umi grabbed my hand and forcibly inserted it into her bra.

“W-What’s this, the real thing?”

Soft! They’re not inferior to God’s breasts, Umi’s are divine!

“This feels better, right?”

“It’s the best!”

“Mufu fu~! So, we’ll train them from now on, OK?”

“H-Hypothetically speaking…”

“But for now, we shouldn’t let this go big as well to train it, right~?”
