Service Club Senior's Masturbation Show
Ayoung attends the service club. The game never specifies exactly what they do, so I asked her about it.
She explained that they basically volunteer at orphanages, senior centers, and places like that.
To me, that sounds like something I'd never do—seems boring, and probably not many volunteers, right? But when I asked her, she said the service points are a huge boon for job hunting, so surprisingly, a lot of students participate.
Hmm... Well, the important thing is that the service club has a great sub-heroine character from the original story—not quite on Ayoung's level, but still.

That's right, her senior An Subin, the glasses-wearing senior with twin tails. She's got an incredibly youthful face and boasts chest size on par with Ayoung's.
Yep. A total loli big-tits character.
In the original, she and the whole service club, including Ayoung, get hypnotized and fail to recognize Jintae, turning her into a one-off event where she loses her virginity without much fanfare.
I'd just been watching from the sidelines, thinking, 'Loli big tits? This one's gotta be savored properly.' And now that Doctor X—the obstacle—is out of the picture, the chance to claim her has finally arrived.
"With that in mind, Ayoung, can't I hypnotize your service club senior?"
"No♥"
Ayoung refused with a refreshingly bright smile.
I clung to her, kneading her breasts as I pleaded. "Ayoung~♬"
"Aang♥ Really... You really want to do it with my senior too?"
"Yeah!"
Ayoung giggled at her husband's outrageous, beyond-common-sense request.
"Jintae-ya, your sex drive is way too strong♥"
"That's exactly why I want service from both you and your senior to relieve it."
Ayoung pondered helplessly for a moment before saying, "Fine, but on one condition♥"
"Condition?"
She laid out an astonishing condition.
"I'll be the one to hypnotize her for you."
"You'll do it yourself!?"
"Yeah♥ If I hypnotize Senior so she can serve you together with me, then I'll allow it♥"
Good lord... Ayoung personally hypnotizing a girl and offering her to me...
I'd never hypnotized anyone like that before, so I couldn't hide my shock.
Maybe it's because Mio and the others' love for me keeps growing? Whatever the case, this unexpected stroke of luck had me grinning ear to ear.
"Deal! I'll leave it to you, Ayoung! Make it the best service ever!!"
"Got it. Look forward to it, Jintae-ya♥"
And so, I gave Ayoung a separate hypnosis phone I'd prepared and taught her how to use it.
A few days later, she said she was ready.
Time to go claim that loli big-tits senior!
……………

……
I followed Ayoung there. The service club sub-room was a perfectly ordinary clubroom.
Just big enough for about six people, and there sat Senior Subin, wearing her glasses.
Drag
Click!
"Hello, Senior Subin."
"Oh! Ayoung, it's been a while. How've you been?"
She stood up, delighted to see Ayoung.
Holy shit, look at those jiggling tits. She looked way younger than in the game—especially her breasts, which seemed even fattier than Ayoung's, swinging heavily like pendulums.
Ignoring my leering gaze, Ayoung greeted her senior.
"Yes, we moved recently, so things were a bit hectic, but I've been well."
"Glad to hear the move went smoothly. But who's the guy behind you?"
Senior Subin spotted me, tilting her head with a big question mark.
Ayoung smiled and said, "Let me introduce him. This is my boyfriend, Jintae. He was curious about what the service club does, so I brought him along."
"Hello, Senior! I'm Kim Jintae. Nice to meet you!"
"Such a spirited boyfriend. I'm An Subin. Nice to meet you too."
She flashed a lively smile my way, full of the same happy energy as Ayoung's.
Do all service club girls have this vibe?
"Ayoung, you've been glowing lately, and club activities have been sparse. Guess that's why."
"S-Senior!?"
"It's a good thing! Spring has come for our Ayoung, so take good care of her, Jintae!"
She chatted happily with Ayoung and offered me a handshake. I gripped her hand firmly and replied, "Yes!"
"Hehe♥"
With that brief introduction over, Senior Subin turned to Ayoung. "So, what do you want to show your boyfriend?"
"It's not so much something to show as... I remembered what you said last time, Senior."
"Me?"
She tilted her head again with a question mark.
I had no idea what hypnosis Ayoung had planted, so I watched the scene unfold with bated breath, utterly thrilled.
"You said you wanted to try servicing a man, remember?"
"Me? D-Did I...?"
"Yes♥ You said you wanted to try [sexual service] on a man."
The moment Ayoung uttered the keyword "sexual service," Senior Subin's eyes flickered subtly.
That's the trigger, huh.
"[Sexual service]... Ah! Right, I did say that! Thanks for remembering, Ayoung!"
"Hehe♥ No biggie. Jintae's interested in sexual service too, so I brought him. Right, Jintae-ya♥?"
"Yeah! Super interested!!"
Ayoung gave her senior a seductive smile.
"So, Senior, don't you want to practice sexual service on Jintae?"
"I'm game... but is it okay with your boyfriend?"
Ayoung turned to me. "Jintae-ya♥ Can you help Senior practice her sexual service?"
"If it's a request from Ayoung, of course I'll help!"
"Thanks, Jintae-ya♥"
With my permission right there in front of her, Ayoung turned back to Senior Subin.
"Then, Senior, practice sexual service on Jintae."
"Okay! But Ayoung, I've never done sexual service before. What should I start with?"
"Don't worry. I've given Jintae tons of sexual service, so I'll teach you well based on that experience♥"
"Thanks, Ayoung. You're the only reliable junior in the service club."
"Hehe♥ No biggie."
Senior Subin smiled so innocently, and my Ayoung smiled even brighter. It was heartwarming—and insanely hot.
"So, what now?"
"First things first: you have to please a man's eyes. Senior, you've masturbated before, right?"
"Masturbate? Of course!"
Ayoung approached her senior and pointed at me. "For starters, masturbate in front of Jintae to please his eyes♥"
"Got it, Ayoung. Just masturbate in front of your boyfriend, right?"
"Yes, and whisper..."
"Whisper...? Like, say stuff that turns guys on?"
"Exactly♥ Jintae will love it."
"Okay, Ayoung! I'll give it a shot!!"
With that, she sat in the chair across from mine—I wasn't even sitting yet.
"Okay, Ayoung's boyfriend... I mean, Jintae. I'm starting now, so watch closely. It's my first time, so don't say anything if it's weird... Here goes."
She seemed to recognize the situation as perfectly normal thanks to the hypnosis, but she still hesitated a bit, embarrassed and shy.
But she steeled herself, looked at me, and said, "Then, I'll start masturbating now."
With those words, she spread her legs.
Plain white cotton panties—nothing fancy, but they gave off that pure, untouched vibe that was incredibly erotic. And her pussy was so plump that the cameltoe visible through the fabric was no joke.
As I was thinking that, she continued. "My name is An Subin. I'm 21 years old, and my breasts are 91cm—E-cup. And..."
She gently rubbed her pussy as she spoke.
Damn, that hand motion is turning me on so hard...
"My pussy is still a virgin—never been used."
It wasn't her own idea; it was like she'd heard it from Ayoung and had no choice but to say it, her embarrassment making it all the hotter.
Senior Subin pinched her clit through her panties and explained, "Masturbation is mostly like this—stimulating the clit, or clitoris."
Through the thick mound and white panties, her pink pussy was vividly visible. It already looked like it was getting wet, and she started stimulating her clit.
"Like this, rubbing the clit... Aang♥ while imagining losing your virginity to a hot guy. Aaang♥"
Her face flushed with excitement from her own masturbation, wearing the full expression of a bitch in heat, the loli big-tits senior kept her eyes locked on me without looking away, fondling her pussy nonstop.
"Usually, I imagine losing it to a VTS V, but today, specially, I'll masturbate fantasizing about sex with Ayoung's boyfriend right in front of me. Haaang♥"
Without stopping, she looked at Ayoung and said, "Ayoung, I'm gonna masturbate imagining sex with your boyfriend—is that okay?"
"Of course, Senior Subin♥ Masturbate happily."
"Thanks! Time for the real deal!! Haang♥ Ang♥ Ang♥"
As if everything so far had been warmup, she started stimulating her clit even more intensely.
At the same time, Ayoung sidled up beside me. "Hold on, Jintae-ya. Let me pull out your cock to help Senior's masturbation♥"
Slide
My cock sprang out of my pants. Senior Subin stared at it in shock—way bigger than she'd imagined—but didn't stop masturbating.
"Haang♥ Wha— Ayoung's boyfriend's cock is huge!? Ang♥ Are all guys like that!? Aaang♥"
"Jintae's cock is special, Senior♥"
"Aaang♥ Losing my virginity to that thing would hurt so much, haang♥"
Ayoung smiled seductively at her senior while gently stroking my cock with her hand.
"Not at all. Jintae's cock feels amazing. Despite the size, it slips in soft and squishy, sticks to all the good spots, and stimulates them♥"
"Aang♥ R-Really that good?"
"Yes♥ So masturbate to climax feeling good, Senior, then join me in sexual service on Jintae's cock."
"Yeah♥ Got it... I'm cumming—cumming!!! Haaaang♥"
Pssshhhhhh!
Whether my cock really helped or not, the loli big-tits senior climaxed hard, soaking her white panties with her juices.
My cock was on the verge of exploding too—I wanted to shoot a load right then.
Ayoung read my mind, smiled slyly at Senior Subin, and said, "Senior, come over here and give Jintae a paizuri service together with me."
"Okay... Just a sec... Haa... Haa..."
The service in the service club was only just beginning.
