I Became the Yakuza's Babysitter (8)
The young lady improved with each passing day. Her once small and frail body grew larger by the day, and she had put on quite a bit of muscle too. She now carried a real sword with her and swung it with impressive skill.
Her growth was the boss’s happiness, and watching her filled me with deep emotion as well.
Thanks to my help, the boss could smile. Having repaid the favor, I couldn’t hide my joy and spent my days in what felt like constant happiness.
“Young lady? I don’t have any laundry…?”
It happened while I was passing by her room on the second floor during that happy routine, having stepped up there for a quick errand.
At first I climbed the stairs without thinking, but before I could even finish speaking, an uneasy feeling stopped me dead.
[Heuuu… Heuuu.]
If you misheard it, the sound was similar to pained moans. When I focused my hearing, I could also make out the wet splash of liquid.
I wasn’t a fool. As an adult who had already sold his body like a male prostitute, I instantly knew what it was.
The young lady’s already… doing this.
I froze in surprise at the sound of her masturbating, but I quickly pulled myself together and quietly headed back downstairs so I wouldn’t disturb her.
It wasn’t the first time I’d witnessed someone masturbating, but it didn’t stir any particular feelings in me. She felt like a little sister, so I genuinely felt nothing.
I simply realized the young lady had reached that age. The fact that I felt neither sexual desire nor anything else made it all the more strange.
I should stay downstairs at night from now on.
It seemed better not to pay any attention than to create an awkward situation where we’d both end up blushing.
A smile kept spreading across my face as I slipped my phone back into my pocket. It was already late anyway, and it would rain until morning.
I changed into an outer layer and finished preparing to head out.
I already bought condoms and medicine. Should I pick up a few skewers on the way?
Since she had just gotten home, she probably hadn’t eaten dinner yet. I decided to prepare something light for her.
“Welcome! It’s cold outside, so come this way quickly…!”
“First, take this. You have alcohol but no snacks. That’d be boring, right?”
“Wow… just like a god.”
Being Japanese, her reactions revealed her unique traits right from the start.
Stepping inside gave the place a very warm and cozy atmosphere.
Memories flooded back—of being fucked by Detective Shinoda on the futon spread out in that corner, of hugging each other tightly while showering in the small bathroom.
And the memories of her calling me over every night under the pretext of “training” only to take my creampies without a condom. This place felt far more like a love hotel than a mansion.
“The alcohol’s just beer cans. That okay?”
“Of course. I brought chicken skewers as a snack. They should go great together.”
We sat across from each other at the small table. Yui, sitting in a butterfly position in front of me, seemed used to this as she tore open the packaging and cracked open a cold beer.
When the foam rose, she quickly brought the can to her pretty lips and took a long gulp, then tore into the chicken while sporting a foam mustache.
“Kyaah~ This really is the best. Aren’t you eating, Sihyun-chan?”
“I’ll start now.”
Even as I grabbed a skewer, my eyes kept drifting to Detective Yui’s chest.
Since she was home, she wasn’t wearing a shirt or suit pants but a light tank top and short dolphin shorts. The sight of her voluptuous figure captured my gaze.
Fuck, that’s hot.
I took a swig of beer to soothe my burning throat.
“Kya. Uuugh, beer’s great but it makes you so bloated.”
“Then eat some snacks with it. Here, cheers~.”
“Cheers!”
Clink. We tapped our cans together and once again filled our empty stomachs with alcohol.
As we filled our bellies with beer and snacks, the grip I had on my sanity gradually weakened.
Shinoda Yui, who had been staring intently at me, spoke first.
“Sihyun-chan, can I ask you for one favor? It’s my once-in-a-lifetime wish.”
“Mmm~ I’ll at least hear you out.”
“There’s a play I want to try.”
A play she wanted to try. The tempting suggestion made me lean in as I brought the drink to my lips.
“Will you do it?”
“Just tell me first.”
“…Tell me you’ll do it first.”
What the hell does she want to do? Does she want to finger my ass or something?
I had occasionally heard rumors about perverts who liked men’s assholes.
Yui furrowed her brow, lost in thought for a moment, unable to meet my eyes.
“I’ll probably agree to most things… ugh, just say it.”
“P-pang… I want to try it.”
“What?”
Whether from embarrassment or the alcohol, Yui’s face was bright red as her words trailed off.
“I said I want to do pang-pang play!”
“Pang-pang? Uh, what’s that?”
Not even “mama” but “pang-pang.” I asked again, flustered by a term I’d never heard before. Realizing she had made an irreversible choice, Yui’s eyes spun as she seemed to lose her mind more and more.
“Pang-pang play means… I get held like a baby and suck on your cock while you thrust into me… No, what am I even saying? There’s no way this is real, haha. You’re not disappointed, are you? It’s okay if you hate it, just fuck me before we break up!!”
“Aish, shut up. Who said I wouldn’t do it? I don’t know what it is, but it sounds fun, so I’ll play along.”
“Huk, heuuu…”
Already heavily drunk, I shamelessly stripped off my top and laid out the futon.
Yui immediately pushed the table aside and approached me. Swallowing hard, she used my thigh as a pillow and laid her head down.
Her eyes, swollen with desire and anticipation, looked up at me as she stretched her arms out.
“Pa-pang~ Please stroke Yui-chan~.”
“…”
“Ahem…”
Even she seemed embarrassed by her own words; her face flushed as she turned her head away.
Since it looked fun, I decided to play along a little. I placed my hand on her burning forehead and stroked it.
“Does our Yui like this?”
“Heuuung~ Pang-pang. Yui-chan likes this so much.”
Whether the headpats felt good or not, she wore the purest, happiest smile I had ever seen. But I couldn’t just keep stroking her head forever.
Now that I was going along with the play, she grew bolder with her hands. She patted my chest, pressed it with her fingers, buried her nose in the cock swelling beside her face and inhaled its scent.
While pretending to be innocent, she looked at me with a baby-like smile and said,
“Pang-pang, I’m hungry… I want to suck on a protein-packed baby bottle.”
This crazy bitch.
Seeing Yui regress further and further into baby mode the more I indulged her, I responded by pulling out my cock.
The sight of my endlessly erect dick instantly captured the baby girl’s attention. It was a delicious-looking sausage dripping with sweet precum at the tip.
She quietly turned her head, buried her nose against it, then slowly brought her lips closer.
Chup, smack. She sucked the honey with her soft lips and held it in her mouth.
“Ah, be careful not to let your teeth touch.”
“Heuuung… I’m sorry, Pang-pang. Hnguuup.”
This time she stimulated the meat rod without letting her teeth touch it.
Her sticky lips scraped gently against the ridge of my glans like hooks. Her tongue slowly licked the back of the saliva-slicked shaft, gradually sucking out the air to create a vacuum.
“Ugh, that feels good.”
“Heuuung… Pang-pang.”
My moans seemed to act as fuel; Yui shook her head even more eagerly. Even while focused on the play, her technique improved bit by bit. I closed my eyes and simply enjoyed it.
The sincere baby girl’s fellatio. The way she put strength into her lips—intense yet painless—was incredibly cute.
“I’m going to cum.”
“Baby juice… it’s here!”
Along with a refreshing sensation, Yui’s cheeks puffed out. They gradually shrank, and soon the corners of her eyes curved upward too.
“Ah, fuck, I can’t hold back anymore!”
“Whoa…!”
After sucking my cock like a baby, she couldn’t contain her lust any longer. She pushed down on my shoulders and climbed on top in one swift motion.
“Where in the world is there a baby like this!”
“I don’t know, there must be one somewhere~ Waah, just give me the cock already!!”
Whether she had gone mad or the alcohol was talking, Yui spat out strange words and threw her dolphin shorts aside. The center of her panties was already soaked through with her juices, turning translucent.
They’re white.
In an instant I drove myself all the way in, past the distorted teddy bear drawn on the white cotton panties.
When I pressed firmly against the end of her womb, tentacle-like vaginal flesh coiled around me, once again proving this was a first-class pussy.
“Huuu, you dirty yakuza cock. I’ll purify it with my justice police pussy.”
“Ugh… that’s so cringey. I feel like I’m going to lose my erection.”
“Ah, shut up and just drink!”
Yui picked up one of the scattered cans and chugged the beer. Then she kissed me, passing the alcohol mouth-to-mouth.
Gulp, gulp. The smooth carbonation, the texture, and the alcoholic scent I felt in my throat.
We got drunk together, our heads spinning round and round.
“Huu, huu. Let’s fuck like crazy and I’ll take the day off tomorrow.”
“Ueeeh… I didn’t even plan on drinking that much…”
I was about to close my eyes as I watched Yui place her hands on her firm breasts to bounce her hips.

This is crybaby detective Shinoda Yui-chan…
