The Tank's True Nature

What the hell was this all of a sudden? Faced with a tall beauty demanding I punch her in the stomach, I felt my brain briefly short-circuit. Yeonji stepped toward me in nothing but a thin running shirt, her face faintly flushed — she looked embarrassed herself.

"My ability, Material Conversion, lets me transform my body. I can make it hard, or I can make it soft. That's how I tank."

So she wanted to demonstrate her power? Did that really mean I had to punch her in the gut? Even for a filthy pervert like me, a belly punch felt like a step too far. It wasn't moral guilt, exactly — more a sense that you don't go around smashing a beautiful work of art.

"Do you really have to confirm it that way?"

Sujin said what I'd been thinking. She looked pretty startled herself.

"A tank is the party's shield, so verifying that ability properly matters. The other members have to be able to trust the tank's power, too. That's the only way you can leave the vanguard to them. Don't worry about me. With my ability, Jaeseong could hit me as hard as he wants and I wouldn't get hurt. Jaeseong's stronger than Sujin, right?"

That last bit was a strangely pointed jab at my pride. I wasn't about to rise to that kind of bait, of course. But her reasoning did make a certain amount of sense. She had far more dungeon experience than we did — maybe she wasn't wrong.

"Ahem. Even so, hitting a woman in the stomach feels a bit... you know."

"We rented this ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠place so we could get in sync, didn't we? That means you and Sujin need to confirm my ability properly."

She was being so insistent I had no choice but to go along. Honestly, a rather wicked curiosity was needling at me too. A belly punch, huh... hmm, interesting. She was an ability user and a tank besides — a punch from me wasn't going to hurt her.

"Well then... I'm sorry, but I'll give it a try."

"Okay...!"

Something about her voice sounded a little excited. I threw a punch at Yeonji's abdomen. Naturally it wasn't a merciless haymaker — more of a playful tap.

Thuk!

The kind of hit that wouldn't even hurt an ordinary person. Yeonji frowned at my punch.

"Is that your full power?"

"Ah... no. It's not full power, but hitting you with everything I've got is a bit..."

"I'm being serious right now. Even if you beat me with everything you have, I won't get a scratch. If you're worried about me, you don't need to be."

Her voice sounded a little angry. Was this something to get angry about?

Does she think I was looking down on her? If so, the anger makes sense.

She was a Rank 9 Hunter. I was Rank 10. Strictly speaking, I was her inferior. Of course, I'd jacked up my stats and skill levels with Power of Sex, so my actual ability might well be above hers — but there was still a difference in the ranks the Association recognized.

Fine.

If that's how she wanted it, I'd take this seriously. When I'd tapped her stomach a moment ago, honestly, my dick had twitched a little. Even with my sadistic leanings, that had been light spanking at most — but this... I might be about to meet a side of myself I didn't know existed.

"Then I'll do it properly."

I spread my legs to shoulder width and drew one back. Sensing the seriousness in my stance, Yeonji took a deep breath. I clenched my fist and drove it into her stomach — the kind of power that would send an ordinary person's teeth flying if it connected with their face.

Fwoosh!

The instant my fist connected, Yeonji's belly stretched out like hot mozzarella cheese. An enormous elasticity wrapped around my hand. The springiness gently enveloped my fist and dispersed the force. For a moment, Yeonji became a rubber person. I understood why she'd been so confident.

"Hnn! Hehe! Is that the best you've got?"

Far from pain, Yeonji let out a sweet little moan as she spoke. Material Conversion. An ability made for tanking, through and through. Sujin, watching this, was so stunned her mouth hung open.

"That's not my best!"

Something competitive flared up in me, and I hit her stomach again. This time I put everything I had into it. I was certain she wouldn't get hurt.

Fwoooosh!

My fist sank even deeper into Yeonji's belly. But her body just stretched further to match how far I'd driven in. The rubber elasticity didn't diminish at all, and my attack didn't ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠seem to do any damage whatsoever. Instead, my deeply buried fist was shoved back by the restoring force of her taut body. I went flying backward like a pebble launched from a giant slingshot.

"Whoa!"

A rebound that went beyond mere defense. An incredible ability. Yeonji came over and offered me her hand.

"Oh my. I'm sorry. Are you okay?"

"I'm fine. That's some incredible defense, though. Like you said, I don't think I could lay a finger on you."

"Besides converting to rubber-like elasticity, I can also change to be as hard as steel."

Excellent. We spent the rest of the time testing each other's abilities. Having gained a reliable tank, I felt more secure myself. No — honestly, I was happier about something else. If I got Yeonji, wouldn't I be able to enjoy a huge variety of play? For example, using that magnificent elasticity on her ass...

I indulged in some very pleasant fantasies.

Training was over. We'd spent the hours confirming each other's abilities, checking tactics, and working out how to handle unexpected situations. We used about five hours, and this godforsaken facility tacked on an extra hundred thousand won in rental fees for every five hours of use. Normally, using more would get you a discount — this place completely defied that common sense. Those bastards.

"Sujin. Want to head home first today? I've got a little errand to run."

"Huh? What kind of errand?"

"Heh. That's a secret. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I'll tell you when I get back."

Sujin had clearly been looking forward to going home and having sex — her face showed her displeasure — but she let me go without a word of complaint. She was already my love slave. Of course it would never happen, but even if I told her to sell her body, she'd obey. I sent Sujin off first and went looking for Yeonji.

"Yeonji. Good work today."

"Ah. You too, Jaeseong. Sujin... already left?"

"Yes. I should be heading out myself. Oh, come to think of it, you said your home was in Seoul?"

"It's close from here. About ten minutes by bus? Well, you should get going. Good work today."

I pretended to part ways with her, then pulled an item from my inventory.

I attached the Watching Eye to Yeonji and quietly followed her. The Watching Eye had a cloaking function, making it extremely convenient for covert tailing. On top of that, the footage transmitted remotely straight into my mind.

Earlier, when I'd punched her in the stomach, Yeonji had let out a peculiar sound. An ordinary person might not have noticed, but as a super-pervert, I could read the fetish packed into that voice.

She wasn't a normal person. My instincts were screaming it. Come to think of it, a normal person — even with an ability like that — probably wouldn't ask someone to punch them in the stomach.

A beauty with doll-like proportions hiding a filthy perversion? I couldn't stand not adding her to my collection. That's why I'd decided to follow her.

After parting from me, Yeonji suddenly headed for the restroom. With the Watching Eye, I could tail her while keeping plenty of distance. A women's restroom, huh. It was a space with a certain fetish appeal, but I wasn't that interested right now.

The Watching Eye followed her inside. Yeonji went into the stall at the far end.

Click!

After locking the door, Yeonji pulled her leggings down to her knees and sat on the toilet. And already, something surprising appeared.

No panties!? No wonder I couldn't see a panty line. I'd heard people wear thongs with leggings to avoid visible lines, but going completely commando? This is already looking interesting.

What's more, her pussy was a smooth, pale white. Sujin's was white too, but that was because she had atrichia — she didn't grow any hair down there at all. Yeonji, though, seemed to have gotten a wax. When I zoomed in with the Watching Eye, I could see traces of sparse hair growing back. Those traces were incredibly hot.

"Ahh...! Fuck. I was gonna wait until I got home, but I'm soaked. Gotta get it out here. Otherwise my leggings'll be drenched...!"

Yeonji clamped her left hand over her mouth and brought her right hand to the cleft of her pussy. The motion was as natural as a trained handler's — utterly practiced. That kind of boldness in a public place! This wasn't her first or second time.

"Hngh...! Fuck, that belly punch was so goddamn good! Yeah. That's how you gotta hit me — nice and meaty! Fuck, thank god he's different from those other little shits. That guy... his dick looked pretty big too. Should I just jump him? Fuck...! Doing it right next to his girlfriend would taste so fucking good, wouldn't it?"

Unlike when she talked to me, Yeonji muttered vulgar, filthy words as she masturbated — the sight was a complete shock. I held my breath and watched the footage.

"Those useless bastards. Fuck, there's a woman this delicious standing right next to them and not a single one of them makes a move. Fuck...! But that guy had potential. Hnnngh...! I bet he'd slam it into my pussy just as meaty, wouldn't he!? I wanna get fucked so bad! Hngh...!"

My cock started throbbing. This was the real deal. For something like this to walk right into my lap. This was fucking unbelievable. What kind of good karma had I accumulated in a past life? Had I saved a world from destruction or something? Or was the luck I'd invested finally paying off? I couldn't stop the corners of my mouth from curling up. Even an enlightened Buddha would scream with joy from every direction if he saw this.

My heart pounded, but my head stayed ice-cold. Don't ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠rush. Yeonji was already a cute little baby bird that had flown straight into my mouth. I spun the gears in my erotic-novel-author brain, drawing up a grand plan to devour her.

Honestly, that perverted woman would probably spread her pussy for me even if I barged into the stall and jumped her right now. But that was amateur thinking. The way to eat delicious food for a lifetime is simple: eat it little by little, and eat it with elegance. I wanted to devour Yeonji even more deliciously than I had Sujin.

Yeonji masturbated for a full thirty minutes before coming out of the restroom. Her face still looked unsatisfied. She'd definitely go home and jerk off like a monkey. Just imagining it, I leaked pre-cum.
