Akira and Ayaka slipped out through a side exit, avoiding the main areas where SPIU agents were still conducting their investigation.

The walk took fifteen minutes, with both of them constantly checking over their shoulders for any sign of pursuit.

"This drain, how does it work?" Akira asked, breaking the silence.

Ayaka glanced at him, her lips curving into a slight, knowing smile. "I'm a succubus, remember? I act as a heat sink. Your body absorbed essence; I draw it out through... connection. Skin-to-skin, friction, binding our energies. It's the only way to siphon it safely without alerting their scanners."

Akira swallowed. "So, like a ritual? Sounds intense."

"Exactly," she replied, with a hint of seduction in her voice. "Desperate times call for it. We don't have much choice. If we don't purge this now, you're walking into a trap."

They pulled up to a warehouse, an old brick building with shattered windows and faded graffiti tags crawling up the walls like veins.

Ayaka led him inside, moving through dusty corridors to a back room cluttered with forgotten crates and shafts of dim light piercing through cracks in the ceiling.

"Here," she said, sliding a rusty bolt across the makeshift door to lock it. "Safe enough. No cameras, no people."

"Seems like you've been here before," Akira observed, but Ayaka ignored that.

"Strip down," she said instead. "We need maximum contact to make this efficient."

Akira hesitated for just a second, the unnatural warmth radiating from his skin making him feel exposed already. He peeled off his shirt, revealing his toned chest glistening with a thin sheen of sweat from the inner heat. "So how do you intend to do this exactly? Walk me through it."

"Like this," Ayaka whispered, stepping close and pressing her lips to his in a sudden, electric kiss.

Her mouth was soft yet insistent, tasting of sweet spice, like cinnamon mixed with something darker, more forbidden. She pushed him back against a sturdy crate, her hands roaming his bare chest, nails grazing his heated skin, sending sparks of sensation through him.

The contact was immediate relief and torment, stirring the fire essence deeper.

"Feel that?" she murmured against his lips. "Your essence is surging already. Let me take it, Akira. Trust me."

Akira groaned low in his throat, his hands instinctively finding her waist, pulling her closer until there was not even a breath of space between them. "Mmmm… your lips taste so good."

"I know," she murmured, trailing her lips to his neck, nipping lightly at the pulse point there, her teeth grazing just enough to draw a hiss from him. "Let me feed on you. I want… no, need more than just a kiss."

She unbuttoned her blouse slowly, revealing inch by inch of smooth, pale skin. Her black lace bra hugged her full, heavy breasts, the fabric straining against her hardened nipples.

The sight made Akira's mouth water, the heat in his core flaring in response.

Even in this desperate situation, he couldn't help but notice how beautiful she was… her demonic markings were slightly visible, tracing patterns across her shoulders and collarbone.

Her fingers worked his belt next, quickly sliding his pants down his thighs to reveal his hardening cock. It was already thick and veined, twitching in the cool air of the warehouse.

"See?" she said in a husky voice as she wrapped her cool hand around his shaft, stroking slowly from base to tip. "You're already responding. See how hard and full you are. Let me relieve you."

Akira's breath hitched, a jolt of pleasure shooting through him as her thumb circled the sensitive head, smearing the bead of precum that was gathering there. "Fuck, that feels good. Your hand... How much do we need? How long?"

"Until the excess drains completely," she said, her eyes locking onto his with dark intensity. She dropped to her knees on the dusty floor, her skirt riding up her thighs. "Skin-to-skin, friction… I'll suck it out first. Open your legs a bit."

Akira spread his stance, gripping the edge of the crate for support as she leaned in. Her tongue flicked out, tracing the underside of his cock from balls to tip, tasting the salty precum with a hum of approval.

The sensation was overwhelming: wet heat contrasting his inner blaze, her tongue flat and broad, lapping at the slit before swirling around the tip.

"Ayaka... deeper," he gasped, his fingers threading into her silky silver hair, urging her on without force.

She hummed in approval, her lips parting to take him in, inch by inch. Her mouth enveloped him, lips stretching around his girth as she slid down his shaft, her tongue pressing against the throbbing vein underneath.

Akira's hips bucked involuntarily, the friction building as she bobbed her head, cheeks hollowing with each suck. Saliva coated him, dripping down to his heavy balls, cooling the overheated skin there.

"Fuck, your mouth... so tight, so good," he groaned, watching her through half-lidded eyes.

"Mmm, your cock tastes just right," she pulled back briefly to say, her lips glistening with spit and precum, a string connecting her mouth to his cock. "Relax your hips, let me take control."

She dove back in, taking him deeper this time, the head of his cock bumping the back of her throat. She gagged slightly, the vibration sending waves of pleasure up his spine, but she didn't stop, relaxing her throat to swallow more.

Her hands joined in, one cupping his balls, rolling them gently, feeling their tightness. The other stroked the base of his shaft in rhythm with her mouth, twisting slightly for added friction.

"Ayaka, shit... don't stop," he urged in a strained voice, his hips thrusting gently into the warmth of her mouth.

"I don't plan to," she mumbled around him with muffled but clear words. She sped up, her head moving faster, slurping sounds filling the room as saliva dripped freely.

Her free hand slipped between her own thighs, rubbing her clit through her panties, her arousal soaking through the fabric. "You're so thick... filling my mouth. The essence is spicy-sweet now, mixing with you."

Akira's grip tightened in her hair, the pressure coiling low in his belly. The essence in him surged with each bob of her head, drawn out by the intimate connection, her succubus nature absorbing it like a sponge.

Too many sensations hit him all at once: the wet sound of her lips, the slight scrape of her teeth, and the cold trail of drool on his skin against the heat building inside.

"I'm getting close already," he warned, his balls drawing up tight. "Ayaka, if you keep that up..."

"Not yet," she pulled off with a pop, her hand still pumping his slick cock, keeping the friction steady. "We can't peak too soon. The drain needs layers… oral first, then more. Stand up straight; let me edge you a bit."

She rose slightly on her knees, angling her mouth to take him sideways, her tongue lashing the sensitive frenulum while her lips sucked the head like a lollipop. Akira's knees buckled; the tease was exquisite torture, and he felt his cock throbbing hard.

"Fuck, you're killing me," he panted, his cock twitching in her grasp. "It feels like... like you're pulling strings inside me."

"That's the binding starting," she whispered, kissing along his length, her breath cooling the wet skin. "Succubus trick… tease the flow, build it up. Now, touch me. Reciprocate; it strengthens the transfer."

Akira reached down and slid his hand under her bra to cup one full breast, his thumb touching the hard nipple. She moaned around his cock, and the vibration intensified everything. Her skin was soft, and her boobs were heavy in his palm. When he pinched her nipple, she drew in a deep breath and sucked harder.

"Yes, like that," she gasped, popping off again to guide his hand lower, under her skirt. "Feel how wet I am? That's from your heat turning me on."

His fingers found her soaked panties, clinging to her wetness. He pushed them aside to stroke her slick folds, parting the pink lips to circle her swollen clit. Ayaka bucked into his touch, her wet and hot pussy leaving a slick coating of juices on his fingers.

"Ayaka... you're drenched," he said, slipping a finger inside her tight channel, feeling the smooth walls clench. "So ready for more."

"We are," she agreed, standing fully now, her hand still stroking him. "But first, let's finish this phase. On your back, on that crate, Akira-kun. I want to ride your face while I suck you. Mutual drain."
