## Chapter 6: Pilates & Yoga Instructor Ha Yeon-su (33 years old / Divorced ♡)
Oh?
I'm surprised by the sensation of sliding all the way in with one thrust, as if her pussy is eagerly swallowing my dick.
Since my lower half enlarged, this is the first pussy to accept me so easily without resistance.
This doesn't mean her pussy is loose like a whore's.
From her attractive appearance that draws men in, she seemed experienced, but rather than being stretched out, it feels like a perfect fit... truly like my personal onahole from a hentai manga.
Since this is my first time experiencing this, and my first time mixing bodies with Ha Yeon-su, I'm not sure how to describe it.
It might simply be the result of long foreplay.
At least the deepest part is still tight.
It feels like I could push in a bit more, but it seems no dick has properly poked her cervix before.
"...What's wrong?"
Surprised by the sensation of sliding in smoothly, I pause. Ha Yeon-su, who was pressing her forehead with the back of her hand, glances at me.
She must have wondered why I stopped moving.
"It's nothing. I'll start moving."
"Um... wait. Since it's so big, don't go too deep..."
Squelch... squish.
"Hngh?!"
"Hah, since it seems no one has reached the end before, I'll open you up."
"Ngh! Ngh! W-wait... Aah... Haah!"
"What's there to wait for? You're already dripping wet, so I'll inaugurate you properly and eat you up deliciously. Just keep your pussy there, instructor."
"Haa, hii! No! Y-you're too big!"
Despite her body twisting like an octopus, I finish developing her smoothly.
As I start thrusting, she wraps around me properly.
The abundant wetness makes penetration comfortable.
"Ah... there, ngh! It's starting to feel okay... Hah! Ungh, hng!"
Though she was saying it hurt terribly just moments ago, she seems to be feeling good now as love juices leak out with each thrust.
The instructor who was just teaching exercise at the academy is now soaking the bed sheets in a round circle below her crotch.
Now it's confirmed.
Ha Yeon-su isn't just lewd on the outside, but on the inside too.
Even her loud whore-like moans are perfect.
Is this what they call the best sexual compatibility?
But I don't dislike this Ha Yeon-su.
Perhaps because I've only fucked through blackmail until now, she's the best fuck - cooperative and sliding in smoothly.
Her body panting while forcibly giving in is the best. It's rewarding to see her face become happy with each thrust of my dick.
And the pleasure of looking at the best female body with wide hips bouncing on my dick.
With each thrust, the fruit ripens more deliciously.
"You really taste good, instructor... How many others have you given this delicious thing to?"
"Hah, d-don't say things like that..."
"How can I not when it's so delicious? It's driving me crazy how you keep moaning in pleasure despite being fucked under blackmail."
"It's not like thaa- Ah! N-no...!"
Her arms raised trembling, gripping the sheets by her head, aren't convincing.
I lower my head to bite her delicious-looking nape and earlobe.
"Haah...♥"
As I press down on her with my chest, giving an appropriate weight, she lets out an even more sensual moan, as if feeling secure.
Her body shakes as if reaching orgasm with each stimulation, so I can't stop the hip movements that pound into this delicious fuck.
"Good, since the instructor seems satisfied too, I'll cum for the first time soon."
As soon as I finish speaking, Ha Yeon-su closes her spread thighs and wraps her legs around my calves, gripping tightly.
At the same time, her thick pussy flesh closes tightly.
The vaginal pressure increases inside the pussy that had accepted me so easily, biting down on my dick.
"If you suddenly tighten like that!?"
"Hngh, hnnnnngh♥"
Ha Yeon-su seems to be reaching her climax after the long foreplay, wrapping around me as she orgasms.
Usually women stretch their legs out, but Ha Yeon-su hugs my shoulders tightly.
The vaginal pressure when her sloppy pussy cums is tremendous. Perhaps because of her trained body, though she calmly accepted my dick at first, when cumming she grips and squeezes tighter than a virgin.
Unable to withstand that pressure, I end up cumming everything without properly feeling the orgasm.
At this rate, I've been milked like a yogurt by Ha Yeon-su.
"Haa... Haa... Haa..."
As her climax ends, Ha Yeon-su slowly separates.
Perhaps embarrassed by the situation and showing her orgasm face from the start, she subtly covers her face with the arms that were just embracing me and catches her breath.
As I pull away from Ha Yeon-su and remove my dick, semen hangs from the tip of the condom like fruit.
After pulling it off and tying it, I place it on the bedside table.
While resting briefly, I stroke Ha Yeon-su's trademark thighs and chat.
"Instructor, your tightening was killer... You instinctively milked the semen at the end, is that because you're at an age where you want to get pregnant soon?"
"I-it's not like that! It just happened... because it was my first time with something like that..."
"You like big dicks? You were moaning loudly throughout sex, you're clearly starved for men."
"...Shut up."
"At this rate, no one would know who was being blackmailed into sex."
"A-anyway! Is this enough now!?"
"Enough?"
I stand up with a start, or rather, an erection.
Until now I was just satisfying my personal sexual urges for Ha Yeon-su, but there are still missions to clear.
As my weakened club regains strength, Ha Yeon-su raises her upper body and covers her mouth.
"It got big again... You're going to do it again right away?"
"I've been holding back for five days since signing up for the academy. Counting each day I saved up, I can easily go five times in a row."
True to those words, as I change condoms, I return to the same full erection condition as when first seen.
Seeing that, Ha Yeon-su's gaze keeps flicking away but ultimately returns to the dick that stirred up her insides.
Unlike other BJs I've eaten, she's full of sexual desire and follows along well, so I make my next request.
"This time, the instructor will have to work a bit, okay?"
"Work...?"
"It's nothing much. Just show me what you usually do."
"...What I usually do?"
Ha Yeon-su's face shows half expectation, half foreboding.
"Come on, don't be nervous. It's simple, something you do every day at the academy."
The first sub-mission was clearly to have sex in yoga positions.
When I order that directly, Ha Yeon-su frowns, but after I whisper the magic word "Zero Two," she reluctantly agrees and slips out of bed.
Then she grabs one leg with her arm and lifts it back, while extending the other arm, demonstrating the standing pose - one of the most basic yoga moves.
From attending the academy, I've even memorized the names.
"...You mean like this?"
Even for a basic pose, a professional is different.
No, Ha Yeon-su is different.
She executes it gracefully while showing off her figure, drawing beautiful lines.
It's exactly like the professional Pilates instructor Ha Yeon-su I saw on stage, the very image I had to watch from afar until now, so I can't hold back.
"Hngh!?"
I immediately go behind her and insert into her pussy in the standing position.
There's a height difference, but it's manageable if I bend my knees slightly.
"Wait, you...!"
"Tsk tsk. Focus on the pose. This is also one of my demands in exchange for keeping quiet."
"B-but your thing is too big... Ah! It's hard to maintain the pose like this...!"
While complaining, she maintains her balance impressively like a pro.
She diligently carries out my unreasonable demands as if it's her own task.
"...Aah♥"
In return, though it's not much, I lick her nape with my tongue from behind and grab her breasts fully.
To stabilize her posture, my other hand holds Ha Yeon-su's stomach.
"You say that, but you're enduring well. Have you done this a lot with men?"
"Th-there's no way I have."
"Why not? It's a waste of talent after learning yoga."
"...This isn't why I learned it."
Soon after, she looks back, seemingly a bit unsure,
"There's no way anyone would make such a perverted request in the first place! You're the first to do something this crazy."
"Yet you're fulfilling that perverted request well."
"That's because I have no choice if I want to keep you quiet..."
"You even danced with your top exposed on adult broadcasts. Aren't you starting to enjoy this beyond blackmail, teacher?"
"..."
She avoids answering.
Since her face is turned away, I'll leave it to imagination whether it's affirmative or negative.
Anyway, she fulfills my request admirably.
Next, she takes a forward bending pose, and that folded position like an old-style phone arouses me again, so I fuck her just like that and cum once more.
The mission said to change positions three times, so after changing condoms, we take the bridge pose on the bed next.
It's a pose that looks like the Chinese character for "person" (人) from the side, similar to doggy style.
Ha Yeon-su's wonderful lower body and buttocks stand out, and I end up stupidly shaking my hips at the magnificent view.
"Hngh, ngh! H-how are you like this! You keep cumming again and again, yet you're still so vigorous...!"
"Must be youthful vigor! You're quite lustful yourself, teacher. How much drool is your lower mouth going to leak!"
"I-I'm only doing this because you're forcing me... I-it can't be helped..."
"Let's say that's true. By the way, our compatibility is no joke. It feels so fucking good every time I stir up your insides, instructor."
"..."
"Don't stop, keep letting me hear your pleasured voice!"
"Ngh! Hngh, unnngh!"
She trembles her thighs while maintaining that pose supported by her arms and toes.
Ha Yeon-su cums lightly. Because she tightens each time she cums, I end up cumming simultaneously again.
Squelch!
I place the used condom aside and tear open a new one to replace it.
The continuous difficult poses have tired me out quite a bit, but there's one last mission left.
The bed is soaked with sweat and love juices.
Ha Yeon-su lies on it covered in sweat, whispering with unfocused eyes:
"Haa... Haa... Still...?"
"This is the last one, so bear with it a little more. Just lie there and I'll do the moving."
I secretly grip my phone and approach, overlapping our bodies.
Unlike the intense sex before, I cover us with a thin blanket and slowly rotate my hips from her wide pelvis, as if savoring the taste.
"Mmm... Ah... Hmm...."
"Does it feel good?"
"I-it's not bad! ...Going slowly is nice in its own way."
"Good, since the instructor seems to be feeling good. I'll just take one shot."
"Take...? ...Ah!"
"Oh."
As soon as she sees the phone in my hand, she quickly turns her head.
Because of that, her face is blurred like a failed cat photo.
"What are you taking!"
"Don't worry. Just one commemorative photo."
"Delete it! Are you going to blackmail me again or leak it online?"
"Would I openly take blackmail material? I even covered us with a blanket somewhat politely."
"Delete it right now!"
Her wariness rises sharply as she gets serious.
"Don't be like that, trust me. If anything, my personal information should be at the academy, so you can report me later if it leaks."
"Why should I trust your... Ngh... Mmm...♥"
I soothe her by slowly rotating my hips as if being affectionate.
"This is the first time I've seen such fantastic lines, so I'm just taking a commemorative photo. Since this is the last time, can't I at least keep some fap material?"
"..."
"Besides, there's no way I'd carelessly show such a precious photo to others, right? Hm?"
"...Just one photo."
"Okay! I'll only take one."
I obtain permission without needing much persuasion.
Since I got permission, I even remove the blanket and sit up to take a proper photo.
But to obscure her identity, she covers her eyes with her hand.
Rather, that clumsy gesture makes Ha Yeon-su look more erotic.
Click!
The photo captures naked Ha Yeon-su embracing me with her waist wrapped around me.
It's quite an arousing image that I'll have to keep for personal collection.
Now the mission is completely cleared.
But since I've already opened a new condom, I might as well get my money's worth before leaving.
I lay Ha Yeon-su down just like that, cover us with the blanket like before, and slowly move my hips.
I savor the leisure and languidness reminiscent of married couple sex.
"Mmm... Ha. Huah... Ngh, unnngh! ...Haa."
Perhaps out of exhaustion, I cum with slightly looser tightening at the end.
I collapse beside her, also tired, and rest briefly to replenish my energy before getting up.
With lingering feelings, I knead Ha Yeon-su's breasts a little before gathering my clothes and bidding farewell.
"It felt good."
"..."
"Since you did well, I'll keep my promise and never reveal this for life. Don't get caught with your adult broadcast hobby and enjoy it diligently."
"W-wait!"
As I try to leave the room, she jumps up and hurriedly reaches out to stop me.
She remains frozen like a statue for a while before eventually saying "It's nothing..." and withdrawing her arm.
Though I feel regretful, I had to leave after seeing the [Mission Successful!] screen that appeared on my phone.
