Eunbi's Potent Lunch
Final exams would be a disaster if things continued like this.
I had barely scraped through midterms, but if this kept up until finals, my GPA would be completely ruined. Maintaining even a high 3.0 would become impossible, let alone anything in the 4.0 range.
Once that happened, I would have to find a way to push my younger sister and Jang Eunbi out of my life for good. I needed time to focus, even if it was only during exam period.
Suddenly, something struck me as odd.
Eunbi had stopped threatening me with photos or videos. At first she had openly blackmailed me with lines like “Phone? Photos? Videos? Audio files?” but lately she never brought any of that up.
After living with her for over a month, I had realized something: she had no real desire to spread my embarrassing pictures or destroy my future. She simply enjoyed toying with her seven-years-older senior. Ruining my life was never part of the plan.
I was certain she would never tell her father, nor post anything on the school bulletin board or send photos to my family. That much I could trust. It wasn’t what she wanted.
Even so, I still couldn’t resist her. No blackmail, no threats—yet whenever she said “Do this for me,” I obeyed without question.
If she told me to cross-dress, I put on women’s clothes. If she wanted photos, I let her take them. When she tapped my rear with the strap-on, I obediently lifted my hips and spread my legs. It was as if my body had learned to submit on its own.
Whether this was habit, my brain being ruled by pent-up lust, or something else entirely, I couldn’t tell.
……Surely I wasn’t starting to like Eunbi?
The thought made me shake my head violently. No. That couldn’t be it. How could I like a woman who blackmailed, feminized, and tormented me? It didn’t make sense. This wasn’t Stockholm syndrome—it was something else.
But the more I denied it, the more an uncomfortable feeling lingered in my chest.
While I was lost in thoughts of Eunbi, the saying “speak of the tiger and it appears” proved true. Footsteps approached the door.
Thud!
It was Eunbi. I no longer flinched when the door swung open so forcefully. My heart no longer skipped a beat. The lack of a knock had become her signature.
At this point, I almost preferred she skip the knock. When she did knock, I tensed up wondering if it might be someone else.
“Yahoo~ Senior, did you ace your last exam?”
Eunbi entered with a bright voice. Her outfit today was different from usual. She wore a cream-colored long knit sweater and black skinny jeans, covering almost her entire body instead of the usual crop tops and miniskirts. It made sense—mid-October had turned quite chilly, with temperatures dropping below 10°C in the mornings and evenings.
“No…… I didn’t do well……”
I answered with a sigh.
“I figured as much. Since you bombed the test and don’t have a single friend to eat with, I prepared a special lunchbox just for you, Senior. Hehe.”
Eunbi set two lunchboxes on the desk with a light tap. They were square containers wrapped in pink cloth and looked quite heavy.
“You made this?”
I asked in surprise. I had never heard that Eunbi could cook.
“Of course. Go on, eat everything. I won’t forgive leftovers.”
She smiled confidently. A faint warmth spread through me and my face flushed. She had gone out of her way to bring me lunch while I was feeling down after the exam. Was she finally treating me like a proper senior? After all the blackmail, cross-dressing, and humiliation, had her conscience finally kicked in?
I opened the lid with cautious hope.
For a moment, the contents seemed to glow.
The first compartment held neatly arranged grilled eel glistening with sauce, drizzled with sweet-savory soy glaze and sprinkled with sesame seeds. The second held golden-brown oyster pancakes. The third was packed with chive stir-fry loaded with shrimp. The fourth contained black bean simmered vegetables and garlic scape salad, with a curled baby octopus tucked in one corner.
The second lunchbox was similarly loaded: white rice, butter-grilled abalone, fresh clam salad, red ginseng extract, and even premium beef tartare.
……Weren’t all of these foods known for boosting stamina?
Eel, oysters, chives, garlic, baby octopus, abalone, clams, red ginseng, beef. It looked like someone had searched “foods that increase potency for men with erectile dysfunction” and dumped every result into these boxes.
“Um…… Eunbi……”
I asked in a trembling voice.
“This…… is it……”
“Yes?”
She tilted her head innocently, though the corner of her mouth curved upward.
“Enjoy your meal, Senior. You’ll need your strength. So lick every bit of sauce off the container with your tongue. Don’t leave a single drop behind.”
If the food had looked terrible, that line would have sounded like torture. But everything looked so appetizing that I let it slide.
“I can’t eat this much……”
“Here, say ah~”
Eunbi popped the metal spoon into her mouth and sucked on it. The silver utensil disappeared between her pink lips and came out glistening with her saliva. She scooped two pieces of eel onto the spoon and held it in front of my mouth.
Seeing the spoon coated in her spit killed my appetite.
“My arm’s getting tired. Hurry up. Say ah~”
“Ugh, don’t you have another spoon?”
This was basically an indirect kiss. She wanted me to eat with the spoon she had just sucked on?
“This is the only one I brought.”
She answered matter-of-factly.
“Come on, eat up. I’ll feed you everything.”
I looked around, but there really was no other spoon. No chopsticks either. Had she deliberately brought only one?
Left with no choice, I opened my mouth and took the spoon. The eel, along with Eunbi’s saliva, entered my mouth. The tender flesh melted on my tongue, and the sweet-savory sauce spread through my mouth. It tasted incredible. I couldn’t remember the last time I had eaten eel. It was expensive, something I never even dreamed of buying for myself.
Once the spoon was empty, Eunbi put it back in her mouth and sucked on it like ice cream. Then she loaded it with oyster pancake and brought it to my lips again.
Was she planning to keep feeding me like this the entire time?
Every bite followed the same pattern: Eunbi sucked the spoon, I ate, she sucked it again. The indirect kiss repeated endlessly.
While I was still chewing the eel thoroughly, the spoon loaded with oyster pancake returned to my mouth.
“Here, say ah~”
“Mmm, mmph. Wait…… just let me finish this first.”
The eel was still in my mouth. I tried to chew and swallow properly, but Eunbi urged me on.
“Why are you chewing so long?”
“I’ve always been the type to chew thoroughly……”
It was a habit since childhood. I usually needed at least thirty chews before I could swallow, but I never expected that habit to backfire in this situation.
“Sigh, you really are high-maintenance, Senior.”
Eunbi let out a breath and smiled strangely.
“Fine. I’ll chew it for you too.”
……What?
She took the oyster pancake from the spoon and put it into her own mouth. She began chewing slowly, her cheeks puffing out and then hollowing again.
Surely…… she wasn’t planning to feed me the way I was imagining?
After chewing thoroughly, she leaned her face closer to mine. Her eyes curved like crescent moons and her lips parted slightly.
“Open wide and receive it, Senior.”
Her face was now so close I could feel her breath. Her eyes stared straight into mine. The moment our lips met, something soft and warm was pushed into my mouth.
It was the oyster pancake she had been chewing.
Ugh…… Honestly, it was disgusting. The thought of eating food that had been chewed by someone else and coated in their saliva triggered an instinctive revulsion. The mushy, wet texture spread across my tongue, mixing the unique briny taste of oyster with something sweet. I couldn’t tell if it was the sauce or Eunbi’s saliva.
Yet strangely, it wasn’t only disgust I felt.
Mixed in with the revulsion was the warmth of her body temperature, the sensation of her lips, and an indescribable sense of intimacy. It was like a baby bird receiving food from its mother—though that comparison felt wrong somehow……
Whatever it was, a complicated emotion I couldn’t explain with simple disgust stirred in my chest.
Gulp.
Before I knew it, I had swallowed. I should have spat it out, but I missed the timing. Or, to be honest, maybe I hadn’t wanted to spit it out at all.
“How is it? Tasty, right?”
Eunbi asked, licking her lips. The corners of her mouth were lifted in clear enjoyment.
“……”
I couldn’t answer. My face burned all the way to my ears and my heart pounded wildly. I couldn’t tell if it was from shame or something else.
“Next is the abalone~”
She placed the abalone in her mouth and spoke while moving her teeth up and down. Was she planning to do this until both lunchboxes were empty?
The two containers suddenly felt enormous.
We repeated the process—Eunbi chewing, me receiving—fifty times. At first the revulsion was strong, but after about ten repetitions it dulled. By twenty it had become familiar, and after thirty it felt almost natural. I was once again reminded how terrifying human adaptability could be. Or perhaps this was less adaptability and more resignation.
Eel, oyster pancake, chive stir-fry, abalone, fresh clams, baby octopus, red ginseng, beef tartare…… Every stamina-boosting food passed through Eunbi’s mouth before entering mine. She never tired of chewing thoroughly for me, and I obediently accepted everything.
By the time I was so full I truly couldn’t eat another bite, the lunchboxes were completely empty. My stomach was so bloated that breathing felt uncomfortable.
“Senior, how was it? My cooking’s pretty good, right?”
Eunbi asked while tidying up the empty containers, looking pleased with herself.
“Yeah…… it was good……”
I answered half-heartedly. To be honest, the taste had been strange rather than simply delicious. Because I hadn’t chewed the food myself and instead received it pre-chewed by Eunbi, the flavors were all distorted. The richness of the eel, the crispiness of the oyster pancake, the chewiness of the abalone—everything had become muted, replaced by the common taste of Eunbi’s saliva in every dish. Sweet, yet faintly briny. I couldn’t decide if that was a good thing or not.
“I’m glad you liked it. I’ll make it for you again next time.”
She smiled brightly.
……She was planning to feed me like this again? Honestly, next time I just wanted to chew my own food.
After finishing the meal and zoning out for about ten minutes, something strange began happening to my body. My blood flow felt off. It was as if all the blood in my body was rushing toward one place—specifically, my lower half. My heart raced, my temperature rose, and my face grew hot.
Was this really happening just because I ate stamina-boosting foods? No matter how good eel and oysters were for that purpose, the effect was far too dramatic for ordinary food.
“Senior, what’s wrong?”
Eunbi asked, tilting her head. Her expression was innocent, but her lips were slightly upturned.
“No, something feels…… weird……”
My breathing grew shallow.
Ugh…… What was this……? It was too strange…… And dangerous……
I shouldn’t stay here in this state. Instinctive warning lights were flashing in my mind.
“Is the effect already kicking in?”
Eunbi said with admiration.
“Pretty effective, huh.”
“What…… what are you talking about?”
“Ah, actually, I ground up about five Viagra pills and sprinkled them in while cooking.”
“What?!”
Viagra? Five pills? Ground up and sprinkled in?
Everything suddenly made sense. A collection of potency foods plus Viagra was bound to produce this reaction. What I had eaten wasn’t food—it was a bomb.
