Akira threw the covers off and scrambled to check his phone. The alarm had gone off at 6:45 AM, but he’d slept straight through it.
"Damn it," he muttered, running his hand through his hair. His body still ached a bit from last night’s battle, but the health potion had done its job. He was functional, at least.
He stumbled to the door and carefully opened it, peering into the hallway. The apartment was quiet; there were no sounds of movement, no voices... nothing. He stepped out fully, looking around.
The kitchen was clean and empty. The main common room looked untouched since last night. The doors to Ayaka, Mia, Rina, and Aoi’s rooms were all closed. Not a single person in sight.
"They must all be at school," he concluded grimly, checking the time again. Nearly 11 AM now. Skipping school wasn’t what he’d planned, but showing up this late would just invite more scrutiny and questions he couldn’t answer.
"So none of them even came to wake me up," he thought aloud, rubbing his tired eyes.
"Nope, darling!" Ai chirped in his mind, her tone taking on a sudden, playful lilt. "I think Mia is still furious with you, and Ayaka probably left you to your well-earned recovery. Can’t say I blame her... you nearly died last night! So you’re basically home alone... though Mrs. Kasai seems to be home."
"Mrs. Kasai?" Akira blinked. "How do you know she’s home?"
"I can sense living beings within a certain radius, darling. Comes with the territory of being a demonic system. And she’s definitely home. Very much awake, too."
Akira sighed, deciding to make the best of his unexpected day off. He wandered into the kitchen and opened the refrigerator, scanning for breakfast options. Eggs, yes. Bread, yes. Milk... nothing.
"Great," he muttered. "No milk."
He stared at the fridge for a moment, then decided to go see Mrs. Mei and ask for some milk. It would also give him a chance to thank her again properly for letting him stay here. He’d been so exhausted last night he’d barely acknowledged her kindness.
He pulled on a clean shirt and a pair of sweats, forcing himself to move quietly down the hall and across the small landing to the other apartment door: Mrs Kasai’s personal residence.
He raised his hand to knock, but before his knuckles could connect, he paused, tilting his head.
There was a strange sound coming from the other side of the door. It was low, muffled, and almost rhythmic.
"What is that?" he whispered.
Akira pressed his ear closer to the door, trying to make out the sound. It was... breathing? Heavy breathing. Someone was definitely in there, and they were breathing hard.
He decided a soft knock was the best approach. Knock, knock.
No response. The sound continued, maybe even got a bit louder.
He tried again, knocking more firmly this time. Knock, knock, knock.
Still nothing. The breathing sound continued, uninterrupted.
"Maybe she can’t hear me?" he muttered, trying the knob.
It turned easily. Unlocked.
"Hello?" Akira called out, pushing the door open just enough to peer inside. "Mei-san? It’s Akira Kanzaki. Are you home?"
The apartment beyond was furnished in a far more traditional Japanese style than his own, very neat and filled with warm, wooden tones. Tatami mats, low furniture, paper screens. Silence met his question at first.
He called again, a little louder this time. "Mrs. Kasai? I just wanted to ask if you had any milk I could borrow?"
No answer.
He stepped inside fully, closing the door behind him out of habit. The breathing sound was louder now, clearer. It wasn’t just breathing; it was almost like... moaning? The sound seemed to be coming from the back of the apartment, near what must be the bedroom area.
"This is a bad idea," Akira muttered to himself. "I should just leave."
But curiosity, and something else, kept him moving forward. He walked past the open kitchen, pausing at the entrance to the hallway. He felt a weird, almost hypnotic pull toward the noise.
"Ahhhh..." The sound was unmistakable now... definitely a moan.
He realised, with a sudden surge of awareness, that he could actually perceive something in the air, like arousal. His new Essence sensitivity was picking up on it.
Without thinking, he activated his Lust Scan instinctually, testing his newly upgraded skills.
[LUST SCAN (LVL 1) - ACTIVATED]
A faint, pink-red glow appeared in his vision, outlining the back room like a heat signature. The glow wasn’t hostile or demonic; it was purely human but intensely focused... concentrated desire radiating from a single source.
"Oh, darling," Ai cooed in his mind. "Do you know what that is?"
Akira swallowed hard, his curiosity now battling with rising panic. "I... I think so."
"Well, don’t just stand there! Go investigate! This is perfect for building your Essence Siphon skills!"
"Ai, this is someone’s private moment. I should..."
"You should what? Run away? After everything you’ve done, now you’re getting shy?"
Akira took a deep breath. His heart was pounding, but not from fear. Something about the concentrated lust in the air was affecting him, making his pulse quicken and his skin feel warm.
He crept down the hall, trying to be as quiet as possible. With every step, the sounds got clearer: soft moans, rhythmic breathing, and the faint rustle of clothing.
The door to the master bedroom was slightly open, just enough to see through if he positioned himself right.
He paused at the edge of the doorway, barely breathing, and peered around the frame.
Mei Kasai was sitting on the edge of her bed with her legs open wide. She was wearing only an oversized, thick white cotton robe that had fallen open from the waist down, revealing the pale skin of her thighs and...
Akira’s breath caught in his throat. His mind went blank for a moment, overwhelmed by what he was seeing.
The pink-red glow of his Lust Scan pulsed brighter, highlighting her form like a beacon of pure desire.
"Well," Ai purred in his mind. "This is certainly an interesting development, isn’t it, darling?"
Mei Kasai was sitting on the edge of her low bed, her thighs trembling around the thick purple vibrator buried deep inside her. One hand worked the toy in slow thrusts while the other pinched a stiff nipple through the cotton.
Akira watched her thighs clench as the vibrator hummed mercilessly against her swollen clit, her wetness coating the toy in thick, glistening streaks.
Her fingers twisted her nipple harder, the sharp pinch sending another wave of heat pulsing through her. A choked moan escaped her lips as her hips jerked.
The headphones clamped over her ears drowned the world in bass-heavy moans from whatever filthy audio she was lost in.
Akira’s upgraded Lust Scan flared pink across his vision.
[LUST SCAN COMPLETE]
[MEI KASAI – CURRENT CRAVING: "Mind-blowing sex, being taken hard by someone who won’t ask permission."]
[KINKS: None]
His cock throbbed painfully against his sweats.
[CHOICE DETECTED]
[A: INDULGE – Hide and begin manual Essence Siphon while observing. High risk of exposure; if caught, Affinity takes a significant hit. REWARD: +50 PP, +30 AFFINITY (Mei Kasai), +5 CONFIDENCE
[B: INTERVENE – Announce presence and apologise immediately. Low chance of success; High chance of immediate panic/anger. REWARD: +10 PP, +5 AFFINITY (Mei Kasai), +10 CONFIDENCE.]
[C: RETREAT – Pretend nothing happened. Low risk. REWARD: +1 CHARM.]
Akira’s answer was almost instant. She hasn’t seen or heard him yet. So he slid silently behind the tall wardrobe, dropping to his knees in the shadows.
"Ai... Essence Siphon, now," he hissed under his breath.
"Greedy boy," Ai purred. "Siphoning engaged."
He freed his aching cock, eyes locked on Mei’s slick fingers plunging the toy deeper into her wet pussy. He watched how her thighs trembled from the pleasure she was experiencing, closing and opening while she continued her actions.
Every moan she let out fed him.
[PP +1... +1... +1...]
Akira closed his eyes as his own pleasure also rose.
His cock throbbed in his grip, pre-cum smearing over his knuckles as he stroked himself faster.
The sight of her, flushed, trembling and her robe barely clinging to her shoulders, made his balls tighten. He could almost taste her from the musky scent of her arousal in the air.
Mei’s breath hitched as she dragged the vibrator down, circling her soaked entrance before pushing it inside with a gasp. Her free hand slid between her legs, fingers spreading her folds wide, teasing the swollen, sensitive flesh.
Akira’s hips bucked into his fist, his thumb pressing hard under the head. He watched her fuck herself with the toy, her tight walls gripping it hungrily, and imagined it was his cock instead.
Her moans grew louder, ragged. "Fuck!!!" she gasped, arching off the bed.
"Fuck, yes," he whispered, stroking fast, matching her rhythm. The essence poured into him like hot honey. "Keep going, Mei-san... just like that..."
Lost in his own bubble of pleasure, he didn’t realise when Mei tried to adjust the headphones, only to hear him. She ripped the headphones off one ear, gasping, "Who’s there?"
Her eyes snapped straight to the wardrobe gap, straight to him.
Akira’s hand froze mid-stroke, holding his big, hard cock in his fist.
Mei’s eyes widened in shock at this sight.
"Oh fuck," Akira cursed.
