An Audacious Outing with Ayeon
After finishing that round of ejaculation and cleanup, we emerged from the alleyway.
We began walking toward our destination, looking reasonably normal—except for the fact that I was grinding my cock against Ayeon's ass right there on the street, all while kneading her breasts beneath her clothes.

"Hehe... O-Oppa... I'm so embarrassed..."
"But Ayeon, you're just too incredibly hot to resist, you know?"
"Ngh... Ah... Mmh..."
Ayeon walked with her head hung low, clearly torn between intense shame and sheer pleasure.
Squeeze, squeeze.
The outline of my hands was completely visible over her shirt, and because she was drenched in sweat, the raw shape of her breasts clung transparently to the fabric. With her mouth still stuffed full of my semen, she seemed even more aroused by the thought of people noticing the sticky white fluid dripping down her thighs.
Squish, squish.
They felt incredibly soft to the touch. When I pressed down and released, they bounced right back up.
Such a good girl, Ayeon, letting me grope her however I pleased right out in public.
The more I fondled them, the more her nipples hardened and her plump breasts swelled, drawing the eyes of everyone around us.
Even without the groping, her thighs and the corners of her mouth were overflowing with the semen she had taken from me. Sticky, pungent strands of my seed—far thicker and smellier than any normal man's—clung to her face and hair. It was so thick, dark, and abundant that there was absolutely no hiding it.
"How does it feel, Ayeon? I think those older guys are drooling over you."
"...Ngh... I-I don't know..."
Whether they heard us whispering or not, the men nearby couldn't help but react to the sight of her.
"Ahem..."
"*Gulp*..."
My hearing had definitely improved since my awakening. I could clearly hear the envious onlookers clearing their throats and smacking their lips in desire.
"Oh my... is she a pervert?"
"Look at that... is she an exhibitionist? Why are kids walking around like that these days?"
"No shame at all... she's an embarrassment to women. Jeez!"
"And why are her tits and ass so huge? She's so petite, did she get surgery or something?"
Insults and judgment swirled around Ayeon from the crowd.
"Mom! Why is that big sister sweating so much? Is she sick?"
"Shh! Don't look at that!"
People whispered and pointed at Ayeon's incredibly lewd state.
"Ngh... Ah... Ahh...!"
Other women watched us with dazed, flushed faces, clearly embarrassed yet unable to look away.
Ayeon tried to squirm and cover herself in shame, but—
Squirrrrrt! Squirt! Squirt!
"Ahhhhh! Oh God...!"
Her hips twitched violently as she squirted yet again. Her desperate, helpless state only fueled my sadistic urges.
Squeeze, squeeze.
After kneading her buttocks for a bit, I slipped my hand directly under the front of her skirt this time, openly fondling her pussy.
Ayeon instinctively moved her arms to cover where my hand had disappeared.
Not that it would actually hide anything, of course.
"Don't cover it."
"Mnh... Ah..."
"Good girl."
She obediently pulled her arms back, thrusting her chest and pelvis forward just as I wanted, making it easier for me to play with her pussy and breasts. In return, I made her slip her hand into my pants to stroke my cock.
To any onlooker, we were performing an incredibly obscene act right in the middle of the street. Yet, despite her overwhelming shame, my sweet Ayeon didn't offer a shred of resistance.
I shoved my fingers deep into her wet slit and began pumping them wildly.
Squelch! Squelch! Squelch! Squelch!
"Haaah! Mnh! Ah! N-Ngh...!"
Love juice flowed endlessly from Ayeon's pussy.
Of course, the passersby could see everything. Because I was standing behind her, reaching around to the front to openly finger her, it was glaringly obvious where my hand was and exactly what I was doing to her.
They could even see the white semen leaking out of her dripping wet folds.

"Her hand... Whoa... Where is his hand going...?"
"Right on the street... Oh my god, they've completely lost their minds!"
"I think that girl's hand is inside his pants too..."
"Wow... he's just thrusting his fingers in so rough like that...?"
"How can he treat a girl so roughly in public... *gulp*..."
"Is that... is that stuff leaking out of her what I think it is...?"
"But... why is there so much of it...?"
"There's no way she did that with just one guy, right...?"
Now, the insults had faded, replaced by gasps of awe and dumbfounded disbelief. Faced with such an outrageous spectacle and the blatant traces of semen, wild rumors and astonished whispers about Ayeon rippled through the crowd.
"Mnh... Ah... Ah... I'm coming... I'm coming! I'm cumming!"
Squirrrrrt! Squirt! Squirt! Hssss...
Overwhelmed by shame, Ayeon had fallen into a state of panic, unable to do anything but moan. Whenever she heard the crowd whispering, her trembling hand would squeeze my cock even tighter.
Her legs buckled, completely drained of strength, and she clung to my shaft just to keep her balance.
To keep her from collapsing forward, I buried my fingers deep inside her pussy while firmly cupping her breasts from below to support her weight.
Shuffling forward step by step, we slowly made our way to our destination.
The place we finally arrived at was a Piercing Shop!
It was a spot I had scouted out a while ago. I had passed by it once, but since I had no interest in piercings back then, I hadn't paid it much attention.
If I recalled correctly, it was a small, dimly lit shop that rarely had any customers.
True to my memory, there wasn't a soul in sight today either.
Though the location was unusual, Ayeon was so desperate to escape the public eye that she hurried inside without a word of complaint. Her brain was likely fried from the endless orgasms, completely saturated with shame and dopamine.
Since she still didn't even realize where we were, I decided to give her pussy a brief rest.
Plop!
The moment I slid my fingers out of her, Ayeon collapsed limply into a nearby chair.
Leaving Ayeon to catch her breath, I looked around the shop to ask about their piercing options.
Fitting for a piercing parlor, there was only one woman inside, sporting piercings on her ears and belly button.
Is that woman standing over there the owner?
"Excuse me... what kind of piercings do you do here?"
"Um... is it for the lady over there?"
The woman asked, staring at my stepsister, who lay completely exhausted in the chair, semen dripping from her pussy and her mouth still coated in it.
The woman's face was flushed with embarrassment. She had likely witnessed our entrance—me shamelessly kneading Ayeon's breasts and shoving my fingers inside her as we walked through the door.
"Yes... the girl sitting over there."
Even I felt a slight pang of embarrassment at having our degeneracy laid bare.
Of course, it was nothing compared to the sheer humiliation my stepsister was feeling.
"Ha... haha. You two are quite intense..."
"Haha, just a bit."
"Well... we do ears, tongue, nose, belly button, nipples, and... even genital piercings. We have a wide variety of options!"
Taking in our disheveled, highly sexual state, the woman immediately let us know that extreme piercings were on the table. She had clearly figured out what kind of service we were looking for.
Ayeon seemed to be regaining her senses.
Realizing where she was, she looked utterly bewildered.
"O-Oppa... don't tell me... the 'present' you mentioned is getting my body pierced?"
She stared at me, her face pale with anxiety and fear.
"Yeah, that's right, Ayeon. This is my gift to you."
"B-But... it looks like it'll hurt a lot... and it'll leave permanent holes..."
"I didn't do this for Hanna. I'm only doing this for you, Ayeon. Because you're special to me."
"...Only for me? What if... what if I say no?"
"Well, then I'll have no choice but to give it to Hanna instead. If you refuse, Hanna will be the first to get pierced."
Ayeon hesitated for a moment, her mind racing, before her expression hardened with resolve.
"I-I'll do it... I want to be first."
"Then where do you want to get pierced?"
"I... I'm fine with anywhere... My breasts...? I'll get it wherever you want!.."
I pondered for a moment. Nipples and tongue seemed like the perfect choices.
Having a metal bead on her tongue would surely provide a whole new kind of stimulation during blowjobs.
And as for her breasts, wouldn't it be incredibly hot if they jingled with little bells every time she moved?
"We'd like to do her nipples and tongue. What kind of designs do you have?"
"Let's see... For the nipples, we have straight barbells with beads on both ends, ones with little bells, hoops, chains... quite a few options."
"For the tongue, we only have straight barbells, but we have two end shapes: a heart or a standard bead."
Both hoops and bells sounded incredibly hot for her nipples. Struggling to choose between the two, I asked:
"Can we attach bells to the hoops?"
"Haha, of course we can. And what about her tongue?"
"Let's go with the heart shape for her tongue."
"Ah... *whew*... In that case... let's see... with these options... the total comes to 150,000 won."
Hmm, that was a bit pricier than I expected. Was it because it was her first time getting pierced?
"Alright. Can I pay now?"
"Yes... *sniff*... Just insert your card here and sign..."
I completed the payment as she instructed.
"Great! Please follow me right this way..."
