The basement lights were dimmed low when Ethan Harlan’s phone lit up twice in quick succession, the screen glow cutting through the quiet hum of his monitors. He had just stepped out of the shower, towel slung low on his hips, water still tracing the defined ridges of his abs from the latest overnight upgrade. The first text was from Lily: a single shy emoji followed by Club room felt too empty today ... miss the way you make everything feel electric. The second came from Mia only moments later: Your place. Tonight. No excuses. I need what only you give me.

He stared at the messages, a slow smile tugging at his lips even as the familiar twist of guilt coiled low in his stomach. They’re both reaching for me at the same time, he thought, thumb hovering over the replies. Lily with that soft honesty that always anchors me, Mia with the fire she pretends isn’t burning her alive. Is this the app pulling strings, or have I actually become the center they can’t stay away from? The power rush answered first—hot, addictive, drowning the doubt in a fresh wave of raw want.

He typed back to both: Basement. Door’s open. Come over.

They arrived within minutes of each other, almost as if the Aura had synchronized their steps. Lily first, slipping in wearing an oversized sweater that slipped off one shoulder and a simple pleated skirt, her braid already loosening from the day’s nervous energy. She crossed the room and rose on her toes to kiss him, small hands sliding under the towel to trace the warm, solid lines of his chest. “I couldn’t stop thinking about yesterday,” she whispered against his mouth, the vanilla scent of her hair mixing with the faint, sweet musk already rising from her skin.

Before he could answer, the door opened again. Mia stepped inside still in her cheer uniform, ponytail swinging, skirt short enough to reveal the long, toned stretch of her thighs. Her eyes narrowed the instant they landed on Lily pressed close to him, a flicker of jealousy sharpening her features. “What the hell is she doing here?” The words came out sharp, but her body betrayed her—the way her nipples peaked instantly against the thin polo, the subtle press of her thighs together as the combined Aura hit them both in the confined space.

Lily stiffened, cheeks flushing, but she didn’t pull away. Instead she glanced at Ethan, then at Mia, the intrusive thought flashing clear in her mind: Watching him with her shouldn’t make me this wet ... but seeing the way her body reacts to him is making me ache in places I didn’t know could throb.

Mia’s own thoughts mirrored the shift, jealousy twisting fast into something darker and hungrier: She’s already touching him like she owns him ... and I want to see what he does to her. I want to watch him make her fall apart the way he does to me.

Ethan felt the tension crackle, then melt. He activated a light charisma nudge through the app, voice low and commanding. “No fighting tonight. You both want this. You both want me. Sit. Talk.” He gestured to the big sectional couch, dropping the towel and stretching out on his back across the wide cushions, cock already half-hard and thickening under their combined stares.

They obeyed, perching on either side of him at first. Conversation started awkward—school, the coding project, the public scene in the cafeteria—but the Aura thickened the air until words became touches. Lily’s hand brushed Mia’s knee. Mia’s fingers trailed up Ethan’s thigh. A charged silence fell, then Lily leaned across him and pressed her mouth to Mia’s in a tentative kiss that quickly turned hungry. Soft lips parted, tongues meeting in slow, exploratory strokes while Ethan watched, his cock now fully hard and resting heavy against his stomach.

“Kiss her the way you kiss me,” he murmured, guiding them. Their mouths moved together above him, breaths mingling, hands exploring each other’s bodies with growing boldness—Lily cupping Mia’s breast through her polo, Mia sliding her fingers under Lily’s sweater to find bare skin. The basement filled with the wet sounds of their kissing, soft gasps, the rustle of fabric as clothes began to come off.
