Ethan leaned back against the cold brick wall outside the art studio. The air was still thick with the remnants of Naomi's scent—her lips, her gasps, her whispered threats.

But there was no time to bask in it.

His HUD flashed again, pulsing crimson.

[Target(s) Detected: Aria & Alina Devaux]

Compatibility: 87% (Aria), 89% (Alina)

Emotional State: Curious. Mischievous. Testing boundaries.

Arousal: 12% (Aria), 15% (Alina) – increasing rapidly.

Twins. Identical. Dangerous.

He remembered the gossip—French exchange students, impossibly elegant, rumored to have broken more hearts than anyone else on campus combined.

Now they were watching him.

Westwood University – Art Building – 10:03 PM

Aria lounged on the deep red velvet couch near the sculpture wing, her legs crossed lazily, a book in her lap that she wasn't reading.

Alina stood at the window, her reflection gazing back at her in the glass. Both wore fitted leather jackets over silky camisoles and mini skirts that caught the studio light just enough to highlight their curves.

Ethan's system buzzed in his ear.

[Sin Insight Activated]

Aria: Craves control. Responds to confident resistance.

Alina: Craves chaos. Responds to risky stimulation.

Great. Two puzzles, one solution. And no room for error.

He stepped inside with practiced calm.

"Evening, ladies."

Aria raised a brow. "Evening? It's nearly midnight."

"Then it's the perfect time for secrets," Ethan said.

Alina smiled, twisting a strand of platinum-blonde hair around her finger. "You're the one they call mysterious, aren't you?"

"Depends. Who's asking?"

"The Devaux twins," Aria said, rising from the couch. Her gaze held fire and frost at once.

"We've heard about you," Alina added, sauntering forward. "Naomi can't stop blushing when your name comes up."

Ethan smirked. "She's not the only one who blushes around me."

[Target Arousal: Aria – 18% → 30% | Alina – 22% → 35%]

"You think you can handle both of us?" Aria challenged.

"I don't think," Ethan replied. "I know."

Aria exchanged a glance with her sister.

Alina grinned. "Game on."

[System Alert: Twin Quest Initiated. Fail Condition: One twin dissatisfied or discovers favoritism.]

Ethan moved to the middle of the room as the twins circled him slowly, like predators studying prey.

He turned to Aria first.

"You look like you want control," he whispered.

She smirked. "And you look like you want to lose it."

He reached for her hand, bringing it to his chest. "Then take it."

She pushed him against a canvas-covered wall, hard enough to rattle the brushes.

"Don't tempt me."

Alina came up behind him, fingers gliding up his spine. "But temptation is the point, isn't it?"

[Dual Arousal Increase: Aria – 41%, Alina – 47%]

His heart pounded, but he kept control.

He turned to Alina now, letting his hand trail up her thigh. "You like chaos?"

She bit her lip. "Make me scream without touching me. That's your challenge."

"Accepted."

He leaned close to her ear, voice like silk. "Picture my hands. Slow. Sliding beneath that skirt. Fingertips tracing every inch, teasing without mercy."

She shuddered.

"Now imagine I stop—right when you're about to lose control."

Alina gasped, eyes fluttering shut.

[Target Arousal: 62%]

He turned to Aria again, pulling her closer by her belt.

"You want control? Then make me beg."

Aria's breath caught. "You're... dangerous."

"No. I'm honest."

And he dropped to his knees.

Aria's dominance flared—she straddled his thigh, grinding gently, her breath hitching.

Alina sat atop the desk behind him, her hand slipping between her own thighs, lips parted as she watched.

[Mission Progress: 48%... 63%... 77%...]

Then Ethan stood suddenly.

"Let's play a real game."

He grabbed two silk ties from the art supply bin.

"Tie me up," he challenged.

The twins exchanged wicked smiles.

Minutes later, Ethan was bound to a chair with his hands behind him. His shirt was gone, his chest glistening with sweat.

Aria sat on his lap, rocking slowly, while Alina straddled the table beside him, whispering dirty fantasies into his ear.

The control dynamic had flipped, but Ethan was still in command.

"You're both so close," he whispered. "But who's going to finish first?"

[Target Arousal: Aria – 89% | Alina – 92%]

Aria's fingers dug into his chest.

Alina's hand slipped into her panties.

The room was hot. Charged. Electric.

[System: Lust Aura II Activated]

The girls cried out almost in sync, trembling against him.

[Mission Complete: Twin Temptation]

[Level Up: Ethan Cross – Level 4]

Later, Ethan stood at the sink in the art room bathroom, splashing cold water on his face.

His reflection stared back at him, flushed but victorious.

Two girls. Two seductions. One power boost.
