Chapter Index

    Ha Yuna was confident.

    “Chup, chuup… Tssop… Haa… Tssop…”

    She was confident that she wouldn’t leave the gym leader’s lips all day today. She was confident that she could suck his tongue and slurp his saliva.

    Even if she liked sweets, eating too many overly sweet desserts at once would make her feel nauseous.

    But this, the gym leader’s saliva, wasn’t like that.

    She didn’t get tired of it. It wasn’t greasy.

    Besides, it was just saliva after all, so there was no need to worry about gaining weight even if she ate a lot.

    So, Ha Yuna clung to the gym leader even more.

    ‘Just a little bit… just a tiny bit more…’

    She hugged his neck as if embracing a loved one, her small chest pressed so tightly that it was almost crushed.

    -Rub… Slide…

    “Chururp… Ahit…!”

    -Wiggle!

    When the gym leader’s hand, which was giving her a butt massage, subtly parted her buttocks, and lightly touched the most embarrassing hole in the middle as it passed by.

    Even she, who was lost in sweet saliva, felt a chilling pleasure spread throughout her body as if she had been electrocuted, and she trembled.

    But still, she didn’t take her lips off.

    It was finally then that she took her face away.

    “Whoaaa… Haa, haa…”

    Breathing roughly, drooling like a moron, she freed the gym leader’s lips.

    It wasn’t because she was tired of the sweetness.

    -Squeak…

    It was because the area between her legs was so itchy that she couldn’t stand it.

    She couldn’t control her body, which had become more excited than when she was crazy for the sweetness.

    ‘I want to masturbate…’

    Carnal desire took precedence.

    So she could drop her face, and in the meantime, she licked out her tongue as if regretting even the thread of saliva that was connected between her lips, which were still erotically linked.

    Now that she had regained some sanity, she realized.

    ‘Wait… I’m, I’m all wet… My, my panties and leggings…!’

    She knew she was getting wet. But she never imagined that her lower body would be so soaked that her bottoms would be completely wet.

    Her lower body was completely wet as if she had spilled water.

    It was clear that this wetness, her fluids, had touched the gym leader’s hand that was rubbing her butt.

    Thanks to that.

    -Hwaaaaa…!

    Ha Yuna’s face turned as red as an apple. She wanted to run to the bathroom or shower room right away, but she couldn’t bring herself to say the words.

    “Ah, uh, ah… Th-there… Ugh…”

    Stammering like an idiot in the most embarrassing situation of her life, she felt the embarrassment growing more and more in the face and gaze of the gym leader right in front of her.

    Her face was about to explode.

    “Yuna.”

    The gym leader’s gentle voice seeped into her ear.

    And.

    -Kiss… Lick

    “Eut…”

    He briefly kissed… no, he overlapped his lips. At the same time, he gently licked over her lips with his tongue.

    Had he finished the health check?

    “The members usually feel good when they receive this health check and massage. So everyone’s clothes get a little… very wet. It’s natural, so you don’t have to worry too much about it.”

    “R-really…? E-everyone is like that… right…?”

    “Of course. Rather, you have to show me this much of a reaction for me to think, ‘Ah, I did a good job.’.”

    To the gym leader’s confident words spoken in a gentle tone.

    “I see…”

    Ha Yuna felt relieved.

    If everyone else was like that, there was no reason to be embarrassed.

    No, of course, it was still embarrassing… but still.

    Thanks to this, she was able to calm down and speak calmly.

    “I’m going to take a sh-shower…!”

    “Yes, yes. Feel free to do so.”

    Feeling relieved was one thing, but she was in a hurry now.

    ***

    Ha Yuna quickly took off her clothes and went into the shower room.

    Her panties and leggings, soaked with fluids, drooped down, but now was not the time to worry about that.

    She went straight to the innermost part and sat down on the floor.

    “Eung…”

    The cold bathroom walls and floor touched her skin. But it wasn’t cold. Her body was not in a state to cool down with something like this.

    -Squeak…

    When she sat down and spread her legs wide, her vagina was clearly revealed, along with a vulgar sound of fluids.

    Cute pubic hair like fluff for a 23-year-old, and a slightly pink vulva covered in sticky liquid.

    A small bean that was definitely erect in the middle.

    Ha Yuna’s hands went to that part without hesitation.

    And.

    -Squeeze… Clench…

    “Ahig…!”

    -Squeak, squeaaak…!

    “Aah…! Here… I like here… Haat…”

    She started masturbating with familiar hand movements.

    One hand harassing her clitoris, and the other hand shoving the tip of her finger into her pussy.

    -Squeak, squeeaaak… Squeak…!

    “Hieut…! Haak, haa…! Aah… Hit…!”

    Unlike her youthful appearance, at this moment, she showed off the allure of an adult woman to the fullest, masturbating her pussy, drooling fluids, and squirting it out.

    ‘Masturbating in the gym shower… feels so good… aah…’

    Ha Yuna usually masturbated a lot. She liked masturbating. Living alone, she did it at least once every two days.

    She was addicted to this pleasurable sensation, but the environment itself was bound to be that way.

    As a VTuber targeting a male audience, she had dealt with many contents that men would be interested in.

    This included slightly erotic comics and animations, as well as chatting with some sexual jokes.

    At first, she only masturbated occasionally when she felt like it because of those things.

    However, as she lived alone, she gradually fell into thoughts and imaginations, and she, who wasn’t particularly interested in the interests that women in their early 20s generally had, gradually became more addicted to mature content.

    She started looking for erotic things on her own, and at some point, even porn. Of course, other girls her age might watch porn, but she did it much more often.

    As a result, she naturally masturbated, and as that continued for a long time, she often imagined various situations.

    Doing it outdoors, in a car, or secretly with a vibrator in a cafe, like she saw in internet stories…

    Of course, she had never actually done it, but she sometimes used that as a basis for masturbating.

    Ha Yuna was that interested in erotic things.

    And thanks to that, now.

    “Haaat… I… got excited by… the massage… Heut… If I open the door… there’s someone there…”

    -Squeak, squeeaaak… Squeak…!

    “Haa, aah, aah! Aheet…!”

    Ha Yuna, with her small nipples standing erect, was enjoying masturbation with a more erotic face than ever before, more excited than ever before.

    `

    The fact that she was excited by a man’s saliva and hands, even though it was a massage and health check.

    The fact that she was masturbating in the gym, a place of learning, not at home.

    The fact that the kind gym leader existed just one… no, two doors away.

    Made her pussy incredibly hot.

    Adding even more to that.

    ‘If… Haaat… If, if the gym leader opens that door and comes in… if he sees me spreading my legs and masturbating…’

    Adding situations that turn her on as imagination, sprinkling seasonings that add excitement and pleasure.

    -Squeak, squeak, squeak, squeak, squeak…!!!

    “Hig…! I, I’m going… I’m gonna cum…! Aaaaaah…!”

    -Pshooooo… Pshoot! Pffft…

    “Haaeeeee…”

    -Tremble Tremble

    In the end, she feels a blissful climax and ends up squirting.

    Squirting pussy water like a water gun, trembling with pleasure in the aftermath of pleasure, with her eyes rolled back and her tongue sticking out.

    “Th-this… is crazy…♡”

    While thinking that she should masturbate here again next time─

    And of course.

    “Just one more time…”

    -Squeaaak…!

    One time wasn’t enough.

    ***

    I was surprised.

    When I was busy licking here and there, lost in the woman’s lips and kiss, Ha Yuna suddenly rushed at me proactively and started sucking my tongue.

    But the surprise was only for a moment, and what followed was great pleasure and excitement.

    I was fulfilled both physically and mentally.

    The feeling of the woman actively sucking on my tongue, inserting her tongue and licking the inside of my mouth, was hard to put into words.

    Every moment was chilling, and I felt so good that I felt like I could stick my lips together and live like that for the rest of my life.

    So I was able to happily accept Ha Yuna’s kiss, which lasted for almost 30 minutes.

    I massaged her butt at the same time.

    Slyly.

    -Slide…

    “Chururp… Ahit…!”

    Touching her butthole too. I didn’t feel dirty at all.

    The fact that I was touching this beautiful girl’s most embarrassing and secret part with my hands was just exciting.

    I was also turned on by the fact that she twitched and trembled every time I touched her, and let out rough breaths and groans.

    Then I also realized that Ha Yuna was drooling fluids from excitement.

    -Squish…

    Because her panties and leggings were completely wet, and it touched my hand on her butt.

    ‘I said my fluids have sweetness and excitement effects, right?’

    The effect was more powerful than I thought. Just how effective was it for her to cling to me and suck my tongue and wet her pussy like this? It doesn’t seem weak at all…

    Well, I’m happy, though.

    And in the end, when Ha Yuna, who realized that she was squirting pussy water, was embarrassed like Jung Ye-sol, I reassured her with similar nonsense.

    “Of course. Rather, you have to show me this much of a reaction for me to think, ‘Ah, I did a good job.’.”

    Yeah, yeah.

    They have to get this wet for me to think, ‘Ah, the gym raising system is working properly.’

    Anyway, Ha Yuna was relieved by my words and went into the shower room, and I also took that opportunity to relieve my excited body in the bathroom.

    While tasting Ha Yuna’s fluids left on my hand.

    “Delicious.”

    I didn’t really taste anything, but it was just delicious. Just like Ha Yuna’s saliva was delicious.

    After that, while waiting for Ha Yuna, whose shower was getting longer, I sat in front of the office computer.

    I was able to see the pop-up window filling the screen.

    ===============================

    “No, wow… just how good was it? She surpasses Jung Ye-sol with just one formal lesson? This is really easy.”

    Her strategy difficulty was seriously the lowest. I thought Jung Ye-sol was also rising steadily, but it was so much faster that it couldn’t be compared.

    As for me, it’s good because I can move forward quickly.

    “Hmm… Should I suck her pussy when she comes out of the shower? I’ll say the health check has to be done down there too.”

    With the idea of completing every corner of Ha Yuna today, now that things have turned out this way, and as my dick was swelling up.

    “Huh?”

    Physical Excitement: 34 (2)

    It was noticeable that the numbers had changed in real time. What that meant was clear.

    “She masturbated twice. I really have to suck her pussy once?”

    Daring to masturbate twice in the sacred gym shower room without the gym leader’s knowledge, this deserves a punishment… no, a reward.

    With that in mind, I waited for her while imagining what Ha Yuna’s breasts and pussy looked like, and what they would taste like.

    A little while later.

    “Gym Leadeeer…”

    “Yes, Yuna… Oh my, you look tired.”

    “Yes… I’m coming after work, so… I have to go home and sleep…”

    Seeing Ha Yuna, who was emitting warmth from her body and slurring her words with a melted face.

    “Pfft… Go in and rest. You worked hard exercising today.”

    I reflexively burst out laughing. Her appearance was so cute that my sexual desire subsided slightly.

    It’s a shame, but there’s nothing I can do.

    She’s a member who comes three times a week anyway, and I can taste her as an appetizer before meeting Lee Da-mi on Wednesday.

    “Give me the leggings. We wash all the members’ workout clothes here.”

    “Ah, th-that… Yes, yes… I’m sorry for getting them dirty…”

    “No, it’s okay. This is all a badge of honor. It means you worked hard and enjoyed it.”

    “…Hehe.”

    Ha Yuna smiled awkwardly, put her panties in her pocket, and handed me the leggings soaked with fluids. Her smiling face was so lovely that I wanted to kidnap her home.

    Hmm. I should masturbate with this once more when Ha Yuna leaves.

    I put it aside for a moment and got up from my seat. Then I gently stroked Ha Yuna’s butt, which was probably not wearing panties, over her jeans and said.

    “From now on, just take off your underwear when you work out. It’s easy to wash these workout clothes, but underwear is a bit inconvenient.”

    “Is it okay to do that…?”

    “Of course. When you come next time, I’ll finish the health check that I couldn’t do today.”

    “Th-thank you…”

    “Then, you worked hard. Go home safely.”

    “Yes…”

    She looked very tired, so I told her to go home quickly, but somehow Ha Yuna didn’t seem to be thinking of leaving right away and hesitated.

    “Eung……”

    She was looking at me, obviously wanting to say something.

    “Do you have anything you want to say?”

    When I asked directly why, Ha Yuna’s face turned red and she said in a small voice.

    “A-no… that is…”

    “Feel free to tell me. I’ll do anything if you need something or want something from me.”

    “Th-then… the health check… just now… the one you do with your mouth…”

    “Yes, yes.”

    “Can I do it one more time before I go…?”

    “Ah ha.”

    She wanted to suck on my delicious saliva one more time before leaving?

    Of course, that’s fine.

    “Yuna.”

    “W-well, if it’s too much trouble, it’s okay…”

    “Let me tell you again. Please ask for those things anytime. I will definitely, of course, do it for you.”

    “Eut…”

    “I’m not just saying this, but I’ll definitely do it for you even if you want it 100 times a day. This is something that Yuna can naturally ask for as a member of our gym. I’m really happy if you tell me this honestly.”

    “Then… you’ll do it now too…?

    “Of course. I can see that you’re healthy, but this also has the effect of calming your mind and body. Okay, look at me and stick out your tongue… Ah, should I stick it out for you?”

    “……Yes. Tongue… please…♡”

    I bent down slightly and stuck out my tongue.

    Then Ha Yuna hugged my neck right away.

    “Tssop… Chuup…”

    She bites my tongue with her lips and starts licking it with her small tongue.

    To this cute creature clinging to me like a puppy, I patted her butt lightly as before.

    Thanks to Ha Yuna’s good self-control, this health check wasn’t that long.

    However.

    “…Should I lend you some clothes?”

    “It’s, it’s okay! I can just tie my cardigan around my waist… My house is close too…”

    Because she got excited in that short time.

    Because she wasn’t wearing panties.

    Because the pants she was wearing were light-colored jeans.

    The fact that Ha Yuna’s pussy was wet was blatantly revealed on the outside.

    It was fortunate that her house was close.

    ***

    Tuesday.

    While spending time studying women’s bodies and sex on the internet to prepare for a possible situation on Wednesday, I received one bad news and two good news.

    First, the bad news is.

    ─Gym Leader… I’m sorry, but I have a big collab… no, a schedule that came up starting today… so I don’t think I can go tomorrow…

    “Really? You can come on Thursday.”

    ─That’s going to last until Thursday…

    “Then there’s nothing I can do. Let’s meet on Friday. If you want to get a refill, you can come more often on a day that’s convenient for you later.”

    ─Yes… I will…

    Ha Yuna is skipping Wednesday’s class.

    I was also disappointed, but somehow Ha Yuna’s voice sounded more sadly dejected than mine.

    But fortunately.

    The first piece of good news helped me forget this disappointment.

    ─Hello. Gym Leader?

    “Yes, Ye-sol. What’s up?”

    ─Is it okay if I stop by the gym for a bit today?

    “Yes? Ah, of course. As I told you before, you can feel free to use the gym facilities anytime. There are no other members’ reservations from now on today.”

    ─That’s… fortunate. Are you free, Gym Leader? Around 5 o’clock.

    “Me? I have time.”

    ─Then can I just get a massage separately today? I’ll pay more if I have to pay extra.

    “Of course you can… Massage? Not a class?”

    ─……Yes.

    “Haha, of course it’s okay. I always provide massages as a free service to my members, so I’m happy to give you one for free if you want. Please feel free to visit.”

    ─Thank you. See you later.

    “Yes, I’ll be waiting!”

    Jung Ye-sol was going to come to the gym this evening, on Tuesday.

    And it was because she wanted to get a massage from me, not for a self-defense class.

    I don’t know why she suddenly wanted a massage, but as for me, I could sacrifice (?) myself as much as the member wanted.

    It seemed like I would be able to taste Jung Ye-sol’s pussy before Lee Da-mi, before Ha Yuna.

    And the second piece of good news is.

    It finally arrived.

    That H toy.

    The item that made my heart flutter just by looking at the name, [Heat Perfume].
