Masturbation in the Succubus's Lair
Rumble!! The succubus lay there reduced to a bloody pulp—a satisfying sight, to be sure—but Yuseong couldn't afford to let his guard down completely. The cave ceiling had started crumbling in a chain reaction.
The first time I met Laila, I pointed that out myself. Back then, he'd stopped her from unleashing a massive spell in those underground ruins. And now here he was, using a bomb to bring the whole cave down... Life sure had a way of throwing curveballs.
But... this was bad. The original plan was to rescue Laila somehow and bolt straight for the exit...
The succubus had kept whipping at him as he fled toward the outside only to circle back, leaving the passage to the exit badly damaged from her attacks. So when the cave began collapsing, that path gave way first, completely sealing it off.
"...Fuck."
Had he acted too rashly? No. His attacks couldn't pierce the succubus's defenses in the first place. She'd even withstood the full force of his trump card, the bomb. If the ceiling hadn't caved in, he'd be the one done for.
"Damn it."
Sweeping Laila into his arms, he bolted—not outward, but in the opposite direction. Deeper into the cave.
God, I hope the back didn't collapse too...!!
Exhausted and carrying Laila on his back, he couldn't pick up speed, but he gritted his teeth and kept moving. As he pushed on blindly, the vibrations and noise gradually faded.
"...Hah, is it over?"
A safe distance from the collapse, he cautiously tapped the walls, wary of a secondary cave-in, but thankfully, it seemed to have stopped completely.
The rock beetles stopped here too, so it should be fine, right? Their senses for danger are supposed to be sharp...
The moment he let out a sigh of relief, the tension drained away, and he collapsed to the ground.
"...I survived."
Once again. He'd made it out alive. Joy surged through him at the thought, but it quickly turned to self-recrimination as he clutched his head.
Why the hell did I do that?
Looking back coldly, his actions had been downright idiotic. In a situation where running would guarantee survival, he'd come up with some lame excuse to turn back and fight the succubus? And his "plan" to take her down was just detonating bombs to bury the cave... If it had gone wrong, he'd have been buried alive too.
And honestly, I got lucky that time. The succubus had held back more power than he'd realized; the moment he closed in, she'd unleashed something new. It was beyond his expectations. He'd have been done for. But...
Replication.
His replication ability, dwelling within him, had repelled that power. Without it, he'd be toast.
"...What the hell was that?"
He'd had no idea replication could do something like that. When Karen had scanned him with mana before, nothing happened... So why had it pushed back the succubus's energy this time?
I don't know.
Sighing at how much he still didn't understand about his own ability, he turned to Laila, collapsed nearby, and gave a wry smile.
"...Well, whatever."
In the end, his choice had saved her. It didn't feel all that bad. Besides, abandoning Laila—who'd tried to save him—would've pricked his conscience, no matter how much he prioritized his own survival.
"...Mm."
With the tension gone, fatigue crashed over him like a wave, drowsiness flooding in. Right—he'd burned through a ton of replication energy copying those disposable magic bombs.
Can't sleep yet. Who knows what's deeper in this cave...
Forcing his heavy eyelids open, he laid Laila down and drew his black iron sword. The succubus threat was over, but you never knew. There could be more dangers ahead.
Muffling his footsteps, he slipped past the rock beetles huddled in the shadows and ventured deeper. At the end, he found a space that felt oddly lived-in.
This place? The succubus's hangout?
It carried a faint trace of that sweet, cloying scent she'd exuded. Unbelievable for a cave: a plush bed, simple living tools scattered about. And a solid wall blocking further progress—the end of the line.
"...Hoo..."
He tapped the walls, checking for hidden spots or lurkers, but his senses picked up nothing. Letting out the breath he'd held, he realized he could breathe easily. Must be some hidden vent.
Rest here for now.
Tension melted away again, and overwhelming sleepiness hit. Stumbling over, he fetched Laila, placed her on what seemed like the succubus's bed, and spread a blanket from his subspace pouch on the hard floor before passing out cold.
Escape and rescue requests could wait.
⋯
...Mm♥
About thirty minutes after Yuseong collapsed from exhaustion.
"...Wh-where... is this...?"
Laila stirred on the bed, throat burning with thirst as she opened her eyes. What she saw: the dim cave ceiling. And a faint lingering aura of lustful magic.
Recalling the moments before she blacked out, she tried to piece things together despite her foggy mind.
Right. I tried to get that man out... against the succubus...
Memories surfaced: using her still-immature shadowless casting to bind the succubus's feet. So this was the succubus's lair?
"Ah♥..."
As she tried to think further, heat bloomed from her lower body, drawing a sweet sigh from her lips. She'd avoided more intake after the succubus fell, but the accumulated lust energy kept tormenting her. Mana had neutralized some while she had it, but now, drained dry, even that was gone.
"Ahh... ha...♥"
And the bed she lay on? The succubus's own. Unintentionally on Yuseong's part, but the lingering scent and pheromones worsened her condition.
'Th-this... isn't right...♥'
Unable to bear the throbbing, she whispered no even as her hand drifted to the hottest spot.
"Ahh!♥"
Her nipple, rock-hard even through her clothes, got a circling rub. A jolt of pleasure shot up her spine, clearing her head just a fraction.
Feeling her mind sharpen slightly, she moved her hand to the most intense throb, mimicking an illustration from a book she'd once glimpsed in her master's study.
-Drip...♥
Her stockings under her skirt were soaked black with juices. Pressing down hard as instinct urged.
-Press♥
"Haaang!!♥"
The moan burst out. Her head cleared more than from her breasts. Realizing this was her only relief, she worked her hands harder.
'My body... it's so weird...♥'
Yanking open her tight top, she exposed her lava-hot breasts. The cool air soothed her nipples briefly, but heat flared again, throbbing renewed.

Gripping and tugging her breasts, pressing her crotch through the stockings, Laila embraced the electric pleasure.
"Ahh... huut...♥"
Her clumsy touch—lifelong devotion to magic left her no experience. Just pressing hard from above. But she knew this was masturbation.
'I shouldn't... do this... Huh? Why not again...?♥'
Her mind, dreamlike from the lust energy. Her body, addicted, instinctively purged it. Laila savored her first masturbation.
Childish fumbling, but her hypersensitive body climaxed easily.
-Spurt!!♥
"Haaah...!!♥"
Stockings stickier, a moan of ecstasy escaped. Some lust energy expelled, she panted, finally able to look around.
Glancing under the bed, there he was, asleep.
'Why...? I sacrificed myself so he could escape...'
Last she saw: her shadowless spell succeeding as he turned to flee. The succubus clicking her tongue, abandoning pursuit for Laila.
So why was he here?
With some lust purged, her thoughts cleared a bit. But hearing her nearby, sleep-rumpled Yuseong cracked his eyes.
"...Laila...?"
She peered down from the bed; he couldn't yet see her state. Half-asleep and confused by her expression, he decided to share the good news first.
"You're awake? Must be disorienting... Anyway, Laila, don't worry. We took down that succubus."
No more threats—he meant to reassure her.
Laila blinked blankly, processing.
...Took down? Who? The succubus? How? Me? No, Yuseong—this guy? Detection magic said she had plenty left. And why was she here?
Skipping to the result left her reeling. As Yuseong yawned, about to explain—
-Throb♥
Her body heated again, lust energy unspent.
"...Ah."
Feeling the succubus's signature lust, her face hardened. Still present, so his claim was a lie. Him here impossibly. She pieced it together.
"It's a dream."
"...Laila?"
Yuseong called, alarmed by her unnatural expression, but she was convinced.
'Heard about it. Succubi trap prey in endless dreams.'
Her knowledge bolstered the theory.
Accepting it as a dream—
-Throb♥
"Ahh!!♥"
Throbbing intensified; mental brakes failed, urges she'd barely suppressed erupting.
-Stroke♥ Stroke♥
Dream logic eroded restraint; her hesitant motions flowed naturally now.
"...Huh? A dream?"
Her odd behavior spurred Yuseong up. He rubbed his eyes at the dizzying sight before him.
