Chapter 17 — Study (2) [18+]
Kim Ain stood up, and I lay down on the sofa.
She tried to get on top of me, but it was too narrow.
“It won’t work on the sofa. It’s too cramped.”
“Should we move to the bed?”
“No, let’s do it on the floor.”
The moment I lay on the floor, my back felt uncomfortable.
“Wait a second. My back hurts too much.”
“Really? Should I bring a blanket?”
“Yeah. I’ll get it.”
We were both so clumsy.
Still, we went through it one step at a time.
I spread the blanket on the floor.
I lay down on it. Kim Ain climbed on top of me, her D-cup breasts bouncing.
“I’m putting it in.”
She grabbed my cock and aligned it with her hole.
Sqqqqqueeeeze.
It went all the way in.
Her waist arched like a bow. She looked up at the ceiling and trembled as if she had been electrocuted.
“This position is way too deep!!”
“Does it hurt? It shouldn’t hurt. It’s perfectly fitted for you.”
“Huh?”
“Never mind. It doesn’t hurt, right?”
“Yeah. It feels good. But… how do I move from here?”
That was something she had to figure out herself.
We were both beginners, but I was slightly better. After all, I had watched a lot of visual materials.
I decided to lead her according to what I had seen.
“Spread your legs like you’re squatting, then try moving your hips up and down.”
“Like this?”
She spread her legs in an M shape.
In that position, she moved her ass up and down, slamming onto me.
Squish. Squish.
It was a new experience.
I wasn’t sure if it was intentional or just ergonomics, but every time she rose, her insides squeezed me tightly. It felt like her vaginal walls were milking my cock.
The way her breasts bounced up and down was amazing too. Every time Kim Ain moved, her breasts shook wildly.
This is great! So fucking good!
I reached out with both hands to grab her bouncing breasts.
“Kyaaak!!!”
The moment my cock slipped out of her hole, Kim Ain slammed back down.
It felt like it got bent. It probably didn’t, but that’s how it felt.
“Uwaaak!!!”
“Sorry! Are you okay?”
“It feels like my bone broke!”
“Is there even a bone there?”
“No, there isn’t. Anyway, I’m fine.”
“You’re fine?”
“Yeah! Keep going.”
The sight of my cock sliding in and out of Kim Ain’s pussy was incredibly lewd.
I wanted to keep watching it, so I told her to continue, but Kim Ain shook her head.
“It’s too tiring. Ah! I know what to do.”
“How?”
Kim Ain realigned my cock with her hole and slid it back in.
“After putting it in like this…”
She started sliding her hips back and forth instead of up and down. At first it was awkward and creaky.
But it only lasted a moment. Soon her upper body began to move like a wave.
Every time she did, her breasts jiggled wildly.
It looked like her back would hurt from all that shaking, so I grabbed them firmly with both hands.
“Ahhng!”
“Does it hurt?”
“It feels good! This feels so good!”
“Really? I liked the previous way better.”
“Ahh! Ahhng!”
Why are you stepping on the accelerator all by yourself?
She shook her pelvis back and forth like crazy.
Looking closely, she was rubbing her clitoris against my pubic bone.
Ah! It’s a hybrid erogenous zone.
Her hole was stimulated by my cock inside her treasure, and moving her pelvis back and forth stimulated her clit at the same time.
I gained another piece of sex knowledge.
“I don’t really like this position.”
The stimulation felt weaker for me. It wasn’t as good as when my cock was thrusting in and out of her pussy.
“Ah!”
“I don’t like it.”
“Ahk! Ahhng!!”
“I prefer the previous position.”
“Aaaaaah~~~~!!!!”
Are you a soprano?
She screamed by herself while shaking her hips wildly.
I want to enjoy it too!
Feeling frustrated, I squeezed her breasts hard and twisted her nipples, but I was overpowered.
Smack.
Kim Ain placed both hands on my chest as if performing CPR.
She didn’t press down to revive my breathing though. What she wanted to revive was my cock. She performed cock CPR by shaking her hips.
It’s already hard!!!
Because Kim Ain leaned her upper body toward me, I had a front-row view of her bouncing breasts, which was nice.
But I!!!
Still, I couldn’t make any demands.
Kim Ain’s eyes were completely glazed over. Like a crazy person.
The hands on my chest gripped so tightly they left marks.
“Does it feel that good?”
“Yeah. This is my first time feeling like this. It’s so good!!!”
“If it feels good for both of us, it’s even better. Want to change positions?”
“Aaaaaahng~~!!”
Found it. Kim Ain’s first movement. Woman on top.
Must be nice, finding a position you like.
Looks like the climax has arrived.
Thud.
Her hip movements suddenly stopped.
She squeezed my chest and screamed.
Drip.
I wasn’t sure if she had cum or if it was just a huge gush of love juice, but I could feel her fluids flowing down my thigh.
“Haa…… Ah……”
She collapsed on top of my body. She was only breathing lightly.
I stroked her head. Her face was hot and drenched in sweat.
“Haa~ Haa~”
“Are you okay?”
“Huh? No, it was amazing. I’m tearing up.”
“It was that good?”
“Yeah.”
“How did it feel?”
“My whole body was tingling, my toes curled up… Ah. It was just too good. Haa… It still feels good.”
“But, you know…”
“Hmm?”
“What if we do it again right now?”
“I can’t right now. The aftershocks—Kyaaak!”
Kim Ain’s head jerked upward. Her waist arched like a bow.
No wonder. Because I moved. I grabbed her hips and thrust upward from below.
“Kyak! Not right now. Just wait until it calms down a bit—Kyaaak! Ah! Ahhng!”
When she tried to get off my body, I wrapped both arms around her back tightly, holding her in place.
Squish! Squish! Squish!
In that locked position, I thrust mercilessly into her.
“Wait. Ah! Juchan Oppa! Wait a second!”
She struggled while getting fucked. Whether from excitement or not, her vaginal walls squeezed my cock tightly, soft and warm.
Thud! Thud! Thud!
I increased the speed. I pounded her as fast as she had been moving earlier.
Kim Ain seemed to like it too.
She shoved her tongue into my mouth. She sucked wildly from the roof of my mouth to my gums.
I was already warmed up from the earlier blowjob and paizuri.
The urge to cum surged rapidly.
Spurt. Spurt.
I poured everything inside her.
Her hole contracted. I moved my hips slowly.
Spurt. Spurt.
I emptied everything into Kim Ain as if milking myself dry.
Round one was over.
***
The ceiling came into view.
Kim Ain was lying beside me, staring at the same ceiling.
“Are you okay?”
“I feel like I’m going to die. It was too good.”
When I looked at her face, her mouth was half open and there were tears.
Kim Ain lay there for a while before she got up.
She looked at my cock. It was covered in semen.
“I need to wash up.”
She wobbled as she stood and staggered toward the bathroom.
I followed the staggering Kim Ain and entered the bathroom with her.
Even the bathroom here is like a palace.
It feels like a hotel.
“It’s embarrassing. Turn your head.”
“Want me to wash you?”
“No, because I have to clean inside too. I’ll wash yours though.”
She put body wash on a shower towel and washed my cock for me.
“Now go out.”
“Okay.”
I started to leave but stopped.
When I turned around, I saw her aiming the showerhead at her pussy and washing it.
The sight was reflected in the mirror, and my cock immediately stood erect again.
Master. Doggy style! Doggy style!
Only this instinct remained.
That was me right now.
I stuck close behind Kim Ain. She looked back at me with a curious face.
“Why?”
“Just a second.”
I made her stand facing the mirror and placed both her hands on the sink.
“Ah. The mirror. You want to do it from behind?”
“Yeah.”
“Okay.”
She didn’t seem unwilling.
The yellow light was on.
But her posture was off. Her back was hunched.
“You have to do it the other way.”
I pressed on her lower back near the erector spinae, and she arched in the correct direction.
Her breasts were now fully visible in the mirror.
Squish.
I thrust all the way in at once.
Slap! Slap! Slap!
I pounded her hard enough to send waves through her ass cheeks.
I reached my left hand forward and grabbed one of her bouncing breasts. With my right hand, I firmly grabbed a handful of Kim Ain’s hair. It was the horse-riding position. I wondered if she would curse, but—
“Ah! Ahh! This position feels good too!”
She opened her mouth wide in satisfaction.
Really? Then let’s go harder.
Smack! Smack! Smack!
I slapped her ass while still holding her hair with one hand.
She still liked it.
Squeeze.
I grabbed both breasts tightly and played with her like a toy.
Slap! Slap!
The sound of flesh colliding filled the bathroom.
This was our second round of sex.
It lasted much longer than the first.
We went at it until we were both drenched in sweat and Kim Ain’s legs were trembling.
The urge to cum came rushing in.
“Huk! Huk! Can I cum inside?”
“I just washed… Do you want to cum in my mouth? You’ve never done that before, right? I want to try it.”
Student Kim Ain is truly a diligent person. Even at this moment, she’s focused on academic research.
Just what I wanted.
“Got it.”
Squish. I pulled my cock out.
I couldn’t make her kneel on the bathroom floor, so I sat her on the toilet.
I aimed my cock at her face and stroked it, but…
Hmm. I’ve become someone who can no longer be satisfied with just my hand. It’s not coming out.
Kim Ain, seeing this, smiled seductively.
“Want me to use my mouth?”
“Will you?”
“Or not.”
“Why are you looking at me with such curious eyes?”
“You said it yourself, Oppa. Men get really excited by visible stimulation.”
“That’s right. That’s why I feel truly happy when your breasts bounce.”
“Then how about this?”
She spread her legs. Her whole body was wet.
She wiped the water off once, then placed her hand on her own treasure. She didn’t stop there.
Squish.
She inserted her own fingers.
“You’ll hurt yourself with your nails.”
“I always keep them trimmed, so it’s fine. Does it turn you on?”
Squish. Squish.
She pushed her fingers in and pulled them out.
My female friend is sitting on the toilet right in front of me masturbating?
And I’m jerking off in front of her?
We really are going all the way.
Kim Ain seemed to have the same thought and laughed with a dumbfounded expression.
“We really are a pair of crazy bitch and crazy bastard.”
“What does it matter? As long as we enjoy it. I don’t think I’ll ever forget today.”
“Me too. I don’t think you’ll ever forget it either, Oppa. Since you’re the one who taught me sex.”
“It’s more like we learned from each other.”
While talking, the masturbation began in earnest.
I fondled Kim Ain’s breasts while stroking my cock.
Kim Ain fondled her own breasts while fingering herself.
The situation was insanely erotic.
The urge to cum rose quickly.
“I’m about to cum!”
“Put it in my mouth.”
I did as she wished. My cock entered between her red lips.
Suck. Suck.
I didn’t even need to move. She moved on her own.
Spurt.
The moment the semen was fired.
Suuuuuck. Suuuuuuuuck.
Kim Ain sucked it all out. Literally.
“Oh. Wow! Woow!!!”
Eureka! Anastasia! Return of the light! Whatever it was, all of it!
It was insane pleasure. It felt like my soul was being sucked out.
Extreme ecstasy and ejaculation continued, and soon everything was drained.
Drip.
White liquid flowed out from the side of Kim Ain’s red lips.
She smiled brightly and opened her mouth.
“Ah~~~”
She showed me the white liquid filling her mouth.
“If it’s hard to swallow, you can spit it out.”
Gulp.
“Huh?”
Gulp. “Mmm. Hehehe. I swallowed it all.”
“You swallowed that?”
“Yeah. I said I’d taste it. You sucked mine too, Oppa.”
“You’re really nice at times like this. How did it taste?”
“It didn’t really have much flavor. A bit fishy? Huh? There’s more coming out.”
When the remaining liquid came out of the urethra, she licked it up with her tongue.
“Hehe. All eaten!”
Her bright smile was so cute.
I stroked her head.
Then she grabbed my balls.
“I’ll crush them.”
“Sorry.”
“Don’t cross the line.”
“Yes ma’am. But why did you want to eat it?”
“Me? Just because. I was curious about the taste, and I thought Oppa would like it. And today is the last day.”
“Wait? What do you mean today is the last day?”
“It’s not fun anymore.”
Suddenly? Did I fail to satisfy her?
That couldn’t be. My cock is a perfect fit for her!
Ah! Was I scammed?
I was about to summon the God of Losers when Kim Ain stood up, walked in front of the shower, and continued.
“Actually, doing it with Oppa felt like a deviation, so it was fun. That feeling of doing something I shouldn’t. Come here, I’ll wash you again.”
She carefully washed my cock and kept talking.
“But now it feels too natural.”
“Ah. So we did it too many times.”
“It’s more that my heart doesn’t race anymore. That feeling like I’m committing a sin? It’s completely gone.”
Not understanding, I grabbed her breasts.
“Wait, why do you need to feel like you’re sinning while having sex?”
“It felt good because it was like rebelling against my parents. But now even when I do it with Oppa, I don’t get that feeling. It feels like you’re someone I’m allowed to do it with. Maybe because we’ve gotten too close.”
There are all kinds of sex fantasies in the world, but I never thought rebellion during puberty would be one of them.
“Ah! There’s another reason!”
“What? I’m curious what kind of wild nonsense is coming next. Ack!!!”
“You wanna die?”
“No. So what is it?”
“You know that bet we made about the investment. To feel the maximum pleasure from that, I think it’s better if we stop doing it now.”
“I don’t quite follow?”
“If I absolutely refuse to let Oppa do it, and then you win the bet, you get to force me to become your slave, right? Just thinking about that situation makes my heart race so much!”
Are you a concept addict?
“To make that happen, you also need to be desperate. So that when I become your slave, you can say ‘You’re fucked. You’re dead!’”
“What exactly are you trying to do?”
Kim Ain pushed my back toward the outside.
“Go home now~ Bye!!!”
“You crazy bitch!!!”
In short, she meant to starve myself as much as possible before eating something delicious.
Still, kicking me out of the house right now feels too much, doesn’t it?
On the other hand, getting kicked out like this somehow makes me even more desperate for the slave play with Kim Ain.
I don’t know. This class was really difficult.
