Chapter Text

It was just after the pentathlon, all the players were scattered in their bunks.

Namgyu watched Mina from across the crowded dorm, his lip curled in disgust. She laughed too loud, swayed her hips too much when she walked, and somehow always got out of the games alive, even though she had the survival instincts of a carrot.

He told Thanos to not let her on the team, how she'd fuck them up too badly, but clearly his bestfriend didn't care about anything other than scoring the hot girl.

She was hot, Namgyu knew that. Probably one of the finest girls there. She was also an idiot.

And tonight, he was going to get rid of her.

He palmed the small pill between his fingers, the one he had managed to sneak out of Thanos's cross necklace. A little blue circle of promise.

“These pills are fucking crazy man!" Damn right they are, Thanos. Exactly what Namgyu needed. That's why he had asked for one in the pentathlon, but never took it. He saved it for someone.

Mina wasn’t smart, but she was strong. And strong people were dangerous in this place. If she was stumbling, unfocused, barely able to stand, she’d be easy prey in the next game. Eliminated. Finally.

“Mina,” he called, his voice dripping with fake charm. He sauntered over, offering her a blue pill. “You’ve been running yourself ragged. Here. Have this. It'll calm your nerves.”

She narrowed her eyes, but her ego was too big to ever suspect she was the target. She snatched the pill from his hand, downed it in one gulp, and rolled her eyes. “Don’t act like you care, Namgyu.”

He smirked as she turned away, her braids damn near whipping him in the face.

But within minutes, something strange happened.

Mina’s steps slowed, not with dizziness, but with heat. Her cheeks flushed, her breaths quickened. She pressed her thighs together, a sharp gasp escaping as though lightning had shot through her veins.

“What the…” she muttered, her hand clutching the nearest bunk. Her pupils widened, lips parting as a sudden, aching hunger took root deep inside her stomach. It wasn’t weakness. It wasn’t pain. It was need. Raw, carnal need.

Namgyu frowned, watching her sway toward the bathroom, her fingers digging into her own skin as if trying to hold herself back. This wasn’t what the pill was supposed to do...

Mina stumbled into the pastel, yet grimy hallway leading to the bathroom, her chest rising and falling rapidly. She creaked the door open and saw him.

Thanos.

The tall, broad-shouldered, purple haired man froze as his wet hands dripped into the sink, his dark eyes locking onto her. He had always liked her-- she obviously knew that, the man didn't exactly hide it. Mina always told him to leave her alone, that she didn't care about whatever pick up line he had for her, Thanos usually just ignored it and never stopped bothering her.

But he had never expected to see her like this. Her lips swollen, her gaze glazed over with desperate lust.

Her teal jacket was wrapped around her waist, defining her figure. The big numbers on her t-shirt, 196.

“Señorita?” he asked, smirking, but cautious. He tried to hide a chuckle before he asked, “Are you… good?”

She stalked toward him, her voice low, husky, dripping with hunger. "I'm good now.”

His throat bobbed. He should’ve backed away. He should’ve asked what was wrong. But as she pressed her body against his, the heat of her breath against his neck, his resolve faltered.

Was this Mina? He thought, the same girl who had always been turning him down?

Her hands were already tugging at his shirt, her tongue trailing the edge of his jaw. “I can’t… I can’t stop. You need to help me. Now.”

Thanos’s mind screamed confusion, but his body betrayed him, hardening, giving in, wanting her as much as she wanted to be taken.

“Mina…” he whispered, as her hand slid lower. “Changed your mind, huh?”

She only smirked, eyes half-lidded, voice a dangerous purr.

“Did I?”

And then, in the flickering light of the filthy bathroom, Mina’s body pressed into his chest, hot and desperate, her breath ragged as she pawed at his shirt.

“Wait—” he tried, but her mouth was already on his neck, wet and hungry, teeth scraping his skin. “This isn't how you usually are…” Even though Thanos was confused, he loved every second of it.

“I don’t care,” she growled, her voice breaking between panting gasps. Her hands slid lower, cupping him through his pants, her nails digging in. “You want me. You tell me all the time. Don't complain.”

He was already hard, his restraint unraveling with every second her body rubbed against his. The drug had turned her into something feral.

Mina shoved him against the sink, her eyes wild, lips parted as she dropped to her knees. Thanos’s breath hitched as her hands tugged at his waistband.

"Mmm, you want this, right?" She looked up at him like a pornstar with her fawn eyes.

"Yes." Thanos answered without hesitation, "Fuck yes. Give it to me, señorita."

As soon as he answered, Mina yanked his tracksuit pants down along with his boxers, making his cock spring up, slapping against his stomach, dripping with precum.

She didn’t wait. Her lips wrapped around him, hot, wet, desperate. Her tongue slid along his length messily, her throat taking him deeper than he thought possible. Her moans vibrated against him, sending shocks through his spine.

He grabbed the edge of the sink, knuckles white. “Slow down… fuck, you’re gonna--”

But she didn’t slow. Drool spilled down her chin, dripping onto her shirt as she devoured him, needy and unashamed. Her eyes looked up, glassy and lust-drunk, and that was it, his last shred of control shattered.

“Mina…” he groaned, fisting her brown locs and yanking her up by her hair to meet his face.

His mouth crashed onto hers, tasting himself on her tongue as he spun her around, pressing her against the sink.

She arched her back, grinding against him. “Do it. Don’t make me beg.”

With one sharp pull, he yanked her pants down, baring her slick heat. His hand slid between her thighs, fingers teasing, already coated in her wetness. She cried out, bucking against him.

"Nah. Come on, show me how much you want it." He demanded.

“Please, Thanos… please… do it already."

Her begging sent him over the edge. He pushed inside her in one rough thrust, both of them gasping at the intensity. Mina clawed at the mirror, her nails screeching across the glass as he pounded her.

The bathroom echoed with the sound of skin on skin, her moans growing louder, rawer, "Thanos.." she moaned, gasping, losing her breath.

Every thrust was deep, mean, his tattooed hands were gripping her waist hard enough to bruise.

“Fuck, you feel so good" Thanos growled, his lips on her shoulder, biting down hard enough to make her whimper. “I didn't know you had it in you.."

“Please, just shut the fuck up and keep going...” Mina begged, the drug fueling every ounce of her feral lust. Her hair clung to her sweaty face, her body shuddering as she met his thrusts with her own.

He chuckled "Look at that, telling me to fuck off all the time, now you're just begging for my cock inside of you."

Their reflection in the cracked mirror showed it all, Mina’s eyes glazed, Thanos’s face twisted with pleasure as he pounded into her. It was filthy and raw.

And when she came, it was explosive, her moan loud enough to be a scream echoing off the walls, Thanos clamped a hand over her mouth so no one would overhear. Her body convulsed, clenching around him. Thanos followed right after, groaning her name as he slid his shaft out and spilled all over her.

For a moment, it silent except for their ragged breaths.

Mina slumped against the sink, her chest heaving, sweat dripping down her skin. Thanos leaned over her, forehead pressed to her shoulder, trying to steady himself.

Mina finally lifted her head, dragging her pants back up, her lips curling into a smile.

“So, what was that about?” Thanos asked, his chest still rising and falling as he lifted his shirt to wipe the sweat off his face.

"Namgyu was right." She giggled through her teeth, "That pill really does relieve stress."

Thanos's face dropped and went cold. "Pill? He gave you a fucking pill?"

"Hm? Yeah?"

He cursed under his breath, "That asshole.."

Mina tightened her ponytail in the mirror, twirling her braids, fixing up her hair. She cleaned herself up aswell.

Thanos stared at her in admiration, like she was the only girl he'd ever seen. She was so beautiful.

But Mina? She paid no mind to him. she turned and walked out the door, slamming it shut behind her, ignoring him.
