Chapter 25. I Can't Keep Up with a Kid's Stamina
After going over the edge from that orgasm control at the end of the rope tie play, I was utterly spent.
It wasn't because Chae-ah was exceptionally skilled.
She'd just tried to mimic the orgasm control I'd done to her during the rope tie and failed.
Simply put, my body couldn't handle this level of stimulation anymore.
I could blame it on quitting exercise entirely after retiring—my body had turned into absolute trash.
"Hah… haah…♡"
"Is the patient feeling worn out?"
"Can we… just rest a bit… before continuing?"
"Time for your shot now. It'll give you some energy, so hang in there just a little longer."
"Sh-shot…?"
Chae-ah had definitely said she was going to give me a shot in the butt.
But there was nothing in the shopping bag that looked like it could play the part of a syringe.
Just as I wondered what she'd use instead, her lips pressed against my ass.
"Chuuup…♡ Chuuuup…♡ How's that, patient? Doesn't hurt, right?"
Who would've thought a kiss on the ass would stand in for the shot.
"Y-yeah…♡"
I'd been worried she'd keep pushing without mercy, but thankfully, she was giving me a moment to catch my breath.
"Chuuuup…♡ Churp…♡"
"Ngh…♡"
"What's wrong, patient?"
I was just about to close my eyes and bury my face in the soft pillow.
But Chae-ah wasn't content with just kissing my ass—she started licking it with the tip of her tongue.
"N-nothing…"
I hadn't expected her to lick my ass, so a moan slipped out—not because it felt that good, but from surprise.
"Your ass tastes so good… I mean, it's so pretty."
Did she just almost say it tasted good?
"Gonna need to keep giving you shots like this."
"Nurse, that's against medical law."
"It's fine, patient. The more shots you get, the better they are. Chuuuup…♡ Churuuup…♡"
She pressed her lips to my ass again, sucking hard this time.
And she licked the flesh she'd drawn into her mouth.
"Hyah…♡"
Maybe because I'd only cum from clit stimulation earlier.
My whole body was hypersensitive now.
"Since you're a bit older, patient, you might need extra shots."
Even if I was starting to feel it a little, that was no comment to overlook.
"You, come here. Making fun of my age again…"
"Churuuuup…♡"
"Fuhi hyaaaang♥"
Just as I was about to make her pay for teasing my age, she pulled my panties aside and licked me all sticky and wet.
The subtle stimulation on my ass had been building, but the sudden intense lick made my body shudder as I let out a moan.
"Tastes so good…♡ Gonna give this spot a shot too."
"Th-there… why a shot…♡ Fuuhgruuut♥"
"It looks tired. That sticky stuff is a classic sign of fatigue."
In my head, role-play had an unspoken rule of maintaining at least a shred of realism.
But Chae-ah's version had thrown realism out the window ages ago.
She just slapped on whatever setting suited her whims.
"You're just… licking because you want to…"
"Churuuuup…♡ No way. Patient, let me lift your hips."
While I was lost in the trembling pleasure, she grabbed my pelvis and hoisted my ass up.
"Th-this…♡ It's kinda embarrassing…♡"
"I was in this position a little while ago, remember?"
Come to think of it, this was the pose I'd put her in when I was leading the role-play.
-Schlurp!
"Hngh…♡"
"Chuuuup…♡"
With just my ass raised high, her tongue on my pussy felt even more obscenely vivid.
"Patient, if you keep squirming, the shot might go in the wrong spot."
"Wr-wrong spot…?"
"Yeah, like… here, for example. Churuup…♡"
"Hiiiiiit♥"
Chae-ah's tongue hadn't touched my pussy.
It was the hole above it—my anus.
"Hey, you…♡"
"Churup… churuuup…♡"
"Hihyaaaang♥ D-don't lick there…♡"
"Why not, patient? You've used it a lot, haven't you?"
"Wh-who said I used it… a lot…♡"
If I masturbated ten times, maybe three involved anal.
But Chae-ah had misunderstood it as my main thing.
"Really? Well, anyway, you've probably used it more than me, so it should be fine. Churuuup…♡"
"Fuhyaaaang♥"
Chae-ah's tongue no longer lingered on my pussy—it stayed glued to my anus.
Here I was, getting rimmed by someone seven years younger.
It was pure humiliation.
Humiliating enough to bite my lip hard, but my body was welcoming her tongue all the same.
"Why… are you so good… at random stuff like this…♡"
"Churup… chuup…♡ churuuup…♡"
"Hnghigiiit♥"
She flicked her tongue tip over my anus, then spread it wide for sticky laps, flowing seamlessly into the rimjob.
All I'd ever felt back there was anal beads or an Aneros.
A rimjob was a first in my life—way too intense to handle.
"Look, honey, pussy juice is dripping down from your pussy?"
"Haa… hagruut…♡ St-stop licking…♡"
"Can I put a finger in, patient?"
My response was a sharp glare.
I might've gotten swept up in the surprise and not refused the rimming properly, but anal fingering? No way—I had to shut that down hard.
"Aw, too bad. Guess we'll save it for next time. Churup…♡"
"Hyaaaaang♥"
-Slap!
She gave my anus one more sticky lick, then lightly smacked my ass.
Which sent me flopping back onto the bed.
"Now, what check-up should we do next?"
As I focused on steadying my ragged breaths and calming my body, Chae-ah pondered the next play.
The long deliberation suggested she was out of ideas.
Seizing the chance to regain control, that's when she yanked off my panties with both hands.
"Oh yeah, you never told me why you were wearing these panties."
"N-no special reason…"
"Really? So you wear ones like this all the time?"
"Of course not…"
"You gotta tell me why, patient."
Chae-ah twirled my panties on her finger with a leisurely smile.
I hesitated to explain because it was embarrassing.
When I'd stopped by the store to grab the nurse cosplay outfit, I'd found those panties bundled with it.
I'd meant to take just the outfit at first, but a weird anticipation bubbled up.
The thought that wearing those panties would make for an even dirtier role-play.
"If you don't tell me, we'll start another check-up."
It didn't fit her previous reluctant vibe at all, leaving me with no choice but to clamp my mouth shut.
"Guess not."
She shook her head and tossed the twirling panties to the floor.
"Final check-up, starting now."
She grabbed my legs, yanked them apart, and dove deep between them.
-Schlurp!
"Hnghruu…♡"
"Shall we rub together, patient?"
Soon, Chae-ah's pussy pressed against mine.
-Schlurp! Squish squish!
"Fuuuuk…♡"
"How's it feel, patient? Good?"
From the moment we touched, Chae-ah started grinding her hips up and down.
To make it more precise, she hooked one of my legs over her shoulder.
-Squish squish squish!
"Hhi hyaaaang♥ D-don't… grind so… fast right from the start…♡"
"Not like this?"
My words sparked pure curiosity in her.
"A bit more… clit to clit… m-move like that…♡"
-Schlurp! Schlurp! Squish squish!
"Like this? Haa…♡ Yeah…♡ Your clit crushing mine… fuuhgruuuk♥"
I'd assumed she'd just grind fast since our pussies were touching, so I gave advice.
I couldn't say exactly why—probably because my sensitized body craved the right stimulation.
"Feels good, patient?"
"Yeah…♡ This is pretty…♡ hyaaaaah♥"
-Schlup! Squish squish squish!
We adapted to grinding so our clits mashed together perfectly, and the pace quickened.
"Haa… hyahuuuk♥ Bumping clits like this… feels sooo good…?"
"Ch-Chae-ah… sl-slow down… a little…♡"
"Haaaaang♥ I'm already… gonna lose it…♡"
Now that she'd discovered clit-on-clit grinding, she brushed off my plea effortlessly.
She was heating up fast, and I was right on the brink too.
"This… feels too good…♡"
-Pahaaaang!
"Hehngruuuk♥"
We'd been grinding clit-to-clit up and down, but suddenly she slammed them together hard.
It was weaker than grinding, but our hypersensitive clits made it a problem.
-Schlurp! Squish squish! Paang! Pang pang pang!
"Ch-Chae-ah… you're too rough…♡ hyahgruuuk♥"
"L-like this… gonna cum… even faster…♡"
Every pussy clash nailed our clits dead-on.
Targeting one spot so relentlessly with that aggressive motion was pure talent.
"Hnghruuuk♥ Un-unni…♡ fuuhiyaaaang♥"
"Hihyaaaang♥"
-Pssshhh!
After relentlessly stimulating each other's clits, we cried out in unison, squirting jets of fluid.
Our spurting streams collided and splashed everywhere.
"Haa… haaut…♡ That was so good…♡"
Chae-ah ground our pussies a bit more before stopping and collapsing into my arms.
"Unni's pussy…♡ is the absolute best…♡"
"Hahk… haah…♡ D-did we… finish…?"
"Yeah…♡ Can't go anymore. Scissoring… takes way more stamina than I thought…♡"
Chae-ah kneaded my breasts softly and beamed up at me.
"Unni."
"Y-yeah…?"
"Did I… do good?"
Her expression was so radiantly bright I couldn't even tsundere my way out.
Guess that's what they mean by not spitting in the face of a smiling person.
"Yeah… you did great. Good job, my Chae-ah…♡"
I even stroked her hair to praise her, figuring she'd sulk endlessly if I said otherwise.
"Hehe. I really love you, unni."
"Maybe I should start exercising again…"
"Huh?"
"Nothing. Let's rest till the hourly room time's up, then head out."
"Okay, unni."
Getting out-stamined by Chae-ah every time had finally sparked some awareness about building my endurance.
