Desert Island BDSM Survival Game - Episode 4: Tutorial

Yumin slowly scanned the square. Most people were alone or paired up in twos. Over half the people here were familiar faces to him, but it seemed the others weren't so lucky.

"Suji sunbae, do you know anyone here?"

"Hmm, let me see. I know Jiwon, and Junyoung and Soyoung too. They're all from our department, right?"

"Yeah, that's right... What about you, Gayoung?"

"Me... That woman over there, Han Mikyung..."

Gayoung's expression soured as she spoke. They clearly weren't on friendly terms.

Yumin turned toward Minseo to ask her next, but she beat him to it.

"None."

Why is she so pouty? Yumin tilted his head slightly. Come to think of it, even during their tutoring sessions, she'd listen well most of the time but occasionally get like this.

The mission had begun. A stir rippled through the once-quiet square.

"What? Soyoung can't do it."

"Junyoung... What do we do..."

The couple who had been clinging tightly started making a fuss. Yumin knew them well—how could he forget? The man's name was Choi Junyoung, the woman's Seo Soyoung. As Suji had just mentioned, they were seniors and juniors from his department.

But Yumin couldn't forget them for reasons beyond that.

----------

As Yumin entered his second year of university, he grew close to Soyoung, a freshman, during the MT welcome trip and started dating her. She was his first girlfriend, and Yumin—timid when it came to women—did his best for her. His family situation meant he had to work for living expenses, so he couldn't always make time, but he squeezed in dates whenever he could. Yumin was happy. He finally understood why his classmates tried so hard to get girlfriends.

Their relationship progressed smoothly until Christmas. Jobs paid premium rates then, a golden opportunity for Yumin's living expenses. He lined up shifts for both Christmas Eve and Christmas Day.

He felt bad about it, though.

Relieved that Soyoung wasn't upset, Yumin finished his shift and headed to the subway. His little sister ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Gayoung was probably still up waiting. Even late at night, the streets teemed with couples. Yumin walked with a bittersweet smile.

Wait, is that Soyoung?

There she was, the girl who'd said she was home with family, smiling brightly. And she wasn't alone—Choi Junyoung, his department senior, was with her.

Yumin ducked into an alley without thinking. What was going on? A chance encounter? But she'd specifically said Christmas was family time.

He rushed home in a daze, gave Gayoung the small gift he'd prepared, and watched her beam with joy. After a quick shower, he lay in bed. But the image of Soyoung walking arm-in-arm with Junyoung kept him awake. It had to be a coincidence. Nothing more. He rationalized it over and over, but it gnawed at him. It was 1 a.m. Soyoung usually stayed up until 2, so he called her.

No answer—straight to voicemail. He tried again. After a long ring, it connected.

The call ended. Yumin's heart pounded. Even he, inexperienced with women and oblivious at times, knew that call was off.

He barely slept that night. The next morning, he called again—no answer until late afternoon.

He couldn't ask about the night before. Just small talk, then hung up.

Soyoung drifted away. By winter break's end, she dumped him.

Yumin had suspected, even braced himself, but it still hit hard. Worse was Junyoung's role. Yumin had treated the friendly senior like a big brother, confiding secrets—including about Soyoung.

Yumin's mindset was rigid: he wasn't ready to commit fully, so he avoided sex. He'd make it right when he could provide properly. Soyoung had given strong signals, but he held back his urges out of care.

Of course he wanted to. But he endured.

New semester: Soyoung and Junyoung started dating. Rumors spread—Yumin's "impotent," "won't even touch a woman offered on a platter." Source unknown, but likely from Soyoung, whispered among department women.

Shattered by his first girlfriend, Yumin swore off dating, distanced from classmates, and buried himself in studies.

----------

"What bullshit is that? She's not doing it."

Oh Juseok, called as the other participant, stormed over yelling. Over 180cm tall, burly, with a scarred left cheek making his face even fiercer.

Junyoung and Soyoung cowered but refused to let go, hugging tight.

Watching, Yumin found it oddly fascinating. Soyoung had dumped him easily for another man. Junyoung exploited her sexual frustrations. Yet their bond ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠seemed unbreakable. Was sex that crucial? Could he have kept her if they'd done it?

To Yumin now, they were strangers—worse than that. He watched their tug-of-war with interest. It might serve as a lesson if Gayoung, Suji, or Minseo faced something similar.

"No way. Soyoung absolutely can't. Angel, please swap the female participant."

Junyoung pleaded skyward as Juseok yanked Soyoung's arm toward the mission room. She resisted; Junyoung clung, refusing to release. Juseok, enraged, pulled hard, scooping Soyoung into his arms and kicking Junyoung's chest as he trailed.

Junyoung let go and crumpled.

Even Angel's usually cheerful voice turned stern. Missions were ironclad.

Banned from violence, Juseok tugged Soyoung, but she resisted, Junyoung clutching his leg despite his bruised chest. They failed to enter in time.

Yumin bid farewell to Gayoung, Suji, and Minseo, then returned to his cell. On the way, he pondered the incident. Three days' fasting was tough but survivable. If similar missions hit his group, they might dodge trouble by cooperating.

But he'd learn how wrong he was three days later.

----------

Angel's cruel words brooked no resistance from Junyoung and Soyoung. Juseok dragged Soyoung to the mission room. They tried to fight, but other participants—worn from three hungry days, irritable and on edge—berated them.

Junyoung reluctantly released her. Soyoung was hauled inside.

The door shut. The wall timer started at 00:29:59, ticking down. A bed rose from the floor center.

Furious from the prior failure and penalty, Juseok manhandled Soyoung, ripping off her top and bottoms. He shoved his cock into her mouth.

She writhed in agony, but he gripped her head with both hands, thrusting brutally back and forth.

"Urgh... Urrph..."

He hoisted her onto the bed, jammed two fingers into her dry pussy, and pistoned viciously.

"Ah... Aah... It hurts..."

No pleasure for her, but her body betrayed her, juices flowing protectively. Juseok rammed his cock in deep and pounded like the bed might break.

"Hngh... Please... gentler... gentler..."

"You bitch, you made me starve three days—makes my blood boil. Gentle? Fuck that."

He rutted harder, checking the clock, adjusting pace, tormenting her for nearly 20 minutes. Finally, he buried to the hilt and came inside.

Pulling out, he revealed her battered form: groin and ass beet-red, breasts bruised from rough kneading.

Unsated, Juseok mauled her breasts again. She cried out in near-scream.

"Tch. Shame. One round's not enough."

Juseok threw on his clothes haphazardly and left. Soyoung struggled up, dressed shakily, and staggered out on trembling legs.

Waiting Junyoung embraced her, but Angel's voice returned. They exchanged longing glances and parted to their cells.

Yumin returned too, deep in thought. Once triggered, missions were mandatory—no skipping. Was there no way to protect Gayoung, Suji, and Minseo?

He racked his brain, but no answers came.
