The Incubus System Chapter 1394. Incubus Biology

“I can’t sleep…”

The words slipped out into the dark like a confession no one was meant to hear. The ceiling above me stared back, pale under the dim city glow leaking through my curtains. The fan spun lazily, blades whispering through the air with a rhythm that should have been soothing. Instead it just counted seconds. Loud. Endless. Annoying.

I rolled onto my side. Then my back. Then my other side. The mattress still held faint warmth and scent from earlier, ghost memories of tangled limbs and breathless laughter, but even that didn’t drag me into sleep. If anything it made my skin itch with leftover energy.

Yeah, dammit. I couldn’t even feel sleepy.

Maybe I did have too much sex tonight. Which, honestly, sounded ridiculous. For most people that would be the fastest ticket straight into unconsciousness. For me? It was like someone shoved fresh fuel into a furnace.

Incubus biology. Sex equals power. Power equals stamina. Stamina equals being wide awake at one in the morning staring at my ceiling like a depressed philosopher who just discovered caffeine for the first time.

I sat up with a groan, running a hand through my hair. My pajamas hung loosely on me, the soft cotton cool against my overheated skin.

I padded barefoot across the floor and pushed my window open. The night air slipped in immediately, brushing my face with that crisp city scent mixed with distant rain and asphalt. The sky stretched dark and deep above the rooftops. Stars were faint here. Light pollution turned them into shy little pinpricks instead of blazing constellations.

I leaned against the frame, arms folded.

I felt… restless. Not horny. Not hungry. Not angry.

Just… untethered.

And without thinking, one name slipped out.

“Emma…”

I blinked, then sighed at myself. Of all people… she was the one my brain picked when I needed to talk.

Weird.

Or maybe not.

I rubbed the back of my neck and glanced at the clock again. Still stupidly late. Still stupidly awake. I exhaled slowly and raised my hand, fingers curling slightly as I used my skills.

[You have opened a portal.]

I didn’t even bother changing clothes. Pajamas, messy hair, bare feet. If she was asleep, I would just peek. Maybe watch her breathing like a certified creep and then leave.

Totally normal incubus behavior.

I stepped through.

The temperature changed instantly. Warmer. Softer. Scented.

Emma’s room always smelled like fresh flowers, and something sweet that reminded me of vanilla and pine sap. The lighting was dim but elegant. Soft golden lamps glowed against pale wooden walls carved with delicate elven patterns. Her carpet was thick enough that my footsteps made no sound when I landed.

And yeah.

Her room was massive.

My room looked like a slightly upgraded dorm closet compared to this. Silk sheets folded perfectly. Pillows arranged like she expected royalty to sleep there.

Except… the bed was untouched.

Neat. Smooth. Cold.

I frowned.

Then the bathroom door clicked open.

Steam rolled out first, carrying the scent of herbal soap and warm water. Emma stepped out, hair still damp, bathrobe tied loosely around her waist. Droplets clung to her collarbone and slid slowly down her neck.

She froze when she saw me.

Her eyes widened. Her lips parted slightly.

“Ethan…” she whispered.

I raised a hand casually. “Just showering? This late?”

She blinked. Then laughed softly, the tension melting out of her shoulders. “I just finished patrol. Demon hunter schedule, remember?”

Right.

She tilted her head, studying me. A slow smile tugged at her lips. “Never thought I would come home and find an actual demon standing in my room instead.”

I grinned. “I’m your favorite demon though.”

I stepped closer, the carpet muffling every movement. She didn’t back away. Never did. I leaned down and pressed a soft kiss to her forehead.

She giggled, cheeks flushing faintly as she leaned into the touch. “So what brings you here?”

Her eyebrow lifted slightly. Mischief already forming.

“Sex?” she added sweetly.

I opened my mouth automatically. Then stopped.

Because honestly?

I had no idea.

“I…” I hesitated. Which, for me, was already suspicious behavior. “I don’t know.”

She blinked again. That softness in her gaze deepened immediately.

“I just…” I scratched my cheek awkwardly. “I feel like talking.”

Her smile turned warm enough to physically hurt. “Talking? Just talking?”

I shrugged. “Sex is also fine with me. But yeah. After what happened in the college today… I think I need to talk.”

Emma stepped forward without hesitation. Her arms wrapped around my waist, pulling me into a hug that was gentle but firm enough to ground me. Her cheek pressed against my chest, damp hair brushing my jaw.

“You came to the right place,” she murmured.

I exhaled slowly, resting my chin on her head.

She pulled back slightly and tugged my sleeve. “Come sit.”

I let her guide me toward her bed. The mattress dipped softly when we sat, ridiculously comfortable compared to mine. The sheets smelled like lavender and something faintly sweet, probably her fabric oil again. The texture alone made my muscles loosen just a little, which annoyed me because I had been perfectly composed two seconds ago.

She tucked her legs beneath her, robe shifting just enough to show glimpses of smooth thigh, pale skin catching the warm glow of her bedside lamp. But her attention never drifted from my face. Emma always did that. Made you feel like the rest of the room didn’t exist.

She studied me for a second, then her expression softened.

“Tea?” she asked gently. “I have chamomile. It helps you relax.”

I blinked at her, then gave a small nod. “Yeah… I’d like that. Thank you.”

Her smile brightened instantly. Not the teasing one. The soft, domestic one that honestly felt more dangerous to my composure than anything seductive ever could.

She slipped off the bed and padded toward the small tea counter built along the far wall of her room.

I leaned back slightly, watching her move.
