The Test Is Over, So I Thought We Could Finally Have Some Thick, Passionate Sex With Jisu... Or So I Thought...
The two-week exam period—which could be called long if it felt long, or short if it felt short—had flown by in the blink of an eye.
Unlike that first day when we’d pushed studying to the back burner and spent the morning doing filthy things, from the very next day onward we threw ourselves into our studies with real focus.
We still shared deep skinship like morning kisses and goodnight kisses, but we never crossed the line into anything truly lewd like a uterine kiss.
Because of that, we were both left aching with unfulfilled desire, craving each other’s bodies yet unable to have them. Still, we endured it for the sake of good grades and studied hard.
Time passed like that, and only after Jisu’s final exam—the one scheduled latest of all—finally ended…
…were we able to throw off the shackles that had been binding us and truly take each other.
“You worked hard on your exams, Jisu. They’re all over now.”
“Yeah! I still have my final project left, but the exams are done, so I’m finally free!!”
“Good, good. Then shall we go out for dinner, Jisu? I’ll buy you something delicious…”
“Stop changing the subject, Haru. You’re all prepared, right?”
“…Well, I did bring all the tools over, but…”
“I see~. Then get everything ready while I take a shower.”
“Okay…”
After giving me a light kiss on the cheek, Jisu headed for the bathroom. I turned toward the bed to finish the preparations, just as she’d ordered.
All the tools for torment were already laid out. Now I just had to tie myself up so I couldn’t move.
First, I put a gag in my mouth so I couldn’t speak, then covered my eyes with a blindfold.
Next, I spread my legs and locked them into the shackles connected to both edges of the bed. I cuffed my wrists and threaded the chain through the ring attached to the headboard.
With a sharp click, I confirmed the cuffs and ring were properly connected.
Now I couldn’t lower my arms even if I wanted to, and I couldn’t move my legs no matter how hard I tried.
And since I was, of course, completely naked, I couldn’t hide any of my most private parts. It was an utterly humiliating position.
You might be wondering—who the hell am I tying up while Jisu is in the shower?
As if I would ever bring another woman into our home and tie her up.
Obviously, I had tied myself up.
Then why, you ask, am I tying up my own body instead of tying Jisu up and training her?
To explain that, we need to go back two days.
Two days ago, right in the middle of exam season.
I was lying on the bed, rolling around while staring at my phone.
“I’m so bored…”
Unlike Jisu, who still had two exams left, I had finished all of mine yesterday. There weren’t even any final projects this time, so with the exams over, I was completely liberated.
But since my girlfriend still had tests to take, I had no choice but to continue my life of forced abstinence.
“God, I want to have sex so bad!!”
Now that the driving force of exam studying had disappeared, maintaining this involuntary celibacy was pure torture. If it were still a dangerous time and we genuinely had to hold back, it might have been easier to endure.
But after the procedure where she got an implant specifically so we could have raw, passionate sex whenever we wanted, that “dangerous time” no longer existed for her.
We had thrown all the condoms away. It was now completely fine to creampie her any time. We had promised that once exams were over, we would spend twenty-four hours a day glued together having thick, intense sessions. I could have filled her pussy until there wasn’t a single day it wasn’t dripping with cum.
But all of that was only permitted two days from now—after Jisu finished her last exam.
Right now, all I could do was miserably wait for her with my poor, directionless cock trapped inside my pants.
“Ha… I haven’t even been able to jerk off for two whole weeks…”
The promise Jisu and I had made: no lewd acts during exam period.
That obviously included watching porn.
For someone who had been having thick, passionate sex with his girlfriend every single day, being told to go two weeks without even jerking off was harder than plucking a star from the sky.
In the end, I couldn’t hold out and had secretly taken care of myself once or twice while imagining our sticky moments together, but the guilt hit me so hard that I stopped right away.
“Ugh, guess I’ll just play some games…”
I briefly considered secretly watching porn, but it felt genuinely wrong to do that behind Jisu’s back, so I gave up on the idea immediately.
How could I watch porn when I had a girlfriend who prepared all kinds of cosplays and situational roleplays just to make sure sex with her never got boring? That would make me human garbage who didn’t value her feelings.
With that thought, I headed to the computer room to play games instead.
While Jisu was out taking her test, I wanted to feel her scent even a little, so I sat in her chair and turned on the computer.
I was looking for the icon on the desktop to play a quick round of League when something caught my eye—an unfamiliar image file sitting on the edge of the screen.
“What the hell is this?”
I absentmindedly clicked it open—and nearly jumped out of my skin.
Inside was a single erotic comic that appeared to have been drawn by Jisu herself.
“W-what the—?!”
Startled, I immediately moved the mouse toward the X to close it, but I couldn’t bring myself to click.
To someone who had been forced into long-term abstinence, even one piece of arousing adult art was an overwhelmingly powerful temptation.
And more than anything, Jisu had drawn it so damn well that my eyes were glued to it before I even realized what I was doing.
“Whoa… holy shit…”
The story itself was fairly simple: a virgin guy gets devoured by a succubus who shows up at his house one day.
But the way she depicted the actual devouring was no joke. I already knew from watching her work that she was an incredibly talented illustrator, but this piece was so good it would have made even me—who had always sworn he’d never be interested in adult comics—rip my pants off instantly.
“This is insane… and she expects me to hold back after seeing this?”
Jisu had told me not to watch porn, but this wasn’t porn, right? It was just a comic. Plus, it wasn’t drawn by some other woman—it was drawn by Jisu herself. So I wasn’t even looking at another girl.
Rationalizing it like that, I finally gave in to my long-pent-up desire and started stroking.
At the time, I had no idea.
What kind of catastrophe would befall me simply because I had opened that file…
“Haru, I’m home~.”
I had relieved myself thanks to Jisu’s drawing and was feeling a bit refreshed, focusing on my game, when she returned from her test.
She must have changed and showered as soon as she got home, because the Jisu who sat down beside me smelled pleasantly of body wash.
“What are you doing~? Playing games?”
“Yeah. I got bored waiting for you, Jisu…”
“I see. Just relax, Haru~. I won’t bother you.”
“No, it’s fine. You just came back from a test. I can’t just sit here ignoring you to play games.”
Right as my character died, I turned my head and gave her a light kiss on the lips.
Of course, Jisu was very respectful of me when I was gaming. Even if I stayed glued to the screen, she wouldn’t complain. But she never disliked my kisses either, so I always made sure to pay attention to her whenever I had a spare moment, even mid-game.
As expected, she seemed to like the kiss. She let out a happy little laugh and sat down beside me.
“By the way, were you just playing games the whole time I was taking my test?”
“Huh? Uh, yeah, pretty much. I think I played about two games.”
“I see~. You didn’t do anything weird behind my back, did you?”
“O-of course not. I just played games like a good boy.”
“Hmm~. Really?”
Jisu stood up, walked over to me, placed a hand on my shoulder, and continued.
“Your reaction seems a little off for that to be true, Haru.”
A chill ran down my spine. When I looked at her, she was staring at me with a strange smile.
Did she… notice that I jerked off to the comic?
Goosebumps erupted all over my body, but I tried my best to stay calm.
I had cleaned up perfectly, so there was no way she could know I had masturbated. And even if she suspected something, I hadn’t searched the internet, so there wouldn’t be any search history. There was no way for her to find out.
Unless… the file access log was still there.
“Did you know, Haru? Computers keep a record of file usage.”
“What…?”
“And there’s even a function that lets you search it? It’s pretty cool, right~? I’ll show you.”
Since the game had just ended anyway, I had no choice but to let her take the mouse.
With practiced movements, she opened the Run window, typed “recent,” and hit Enter.
And then…
“J-Jisu…”
She slowly scrolled through the recent files, then double-clicked the comic file I had opened. The image of the woman I had just been indebted to appeared on screen, and cold sweat poured down my back.
Jisu smiled as she scrolled through the entire comic, then looked at me and said.
“Haru~.”
“Y-yes…?”
“Be honest. How many times did you jerk off?”
“…O-once.”
“Really?”
“Yes…”
When I lowered my head, she slipped her hand into my pants and began fondling my cock.
As it started to harden under her touch, she gave a mysterious smile and nodded.
“Doesn’t seem like you’re lying~, Haru.”
“J-Jisu… look, it’s just that…”
“You remember our promise, right? I won’t listen to any excuses, Haru.”
I quietly nodded.
We had agreed that if I got caught watching porn, I would be punished after exams were over.
I could have argued that this wasn’t porn, it was just an erotic comic, but I had a feeling that would only increase the number of punishments I received, so I kept my mouth shut.
“I said I would tie your whole body up and milk ten times the amount of semen you stole from me, remember?”
“Yes…”
“But since our Haru was honest with me, I’ll go a little easy on you~.”
She looked at me with a wicked expression.
“Let’s make it seven rounds of milking.”
“Excuse me…?”
No matter how you looked at it, seven times was still way too much…
I wasn’t the protagonist of some erotic novel. If I came seven times, I might actually die…
But there was no way my inner screams could reach Jisu.
“On the day exams end, prepare all the training tools, tie up your own hands and feet, and lie on the bed waiting for me.”
“Yes…”
In the end, overwhelmed by her intensity, I had no choice but to accept my fate of being milked dry.
