Mira's walls fluttered around him as she rode him harder, her voice breaking into soft cries. Myra's thighs trembled against his ears, her juices coating his tongue and chin.
Noah kept pounding upward into Mira's tight, soaking pussy with everything he had, hips snapping up to meet every downward slam. His tongue delved deeper between Myra's slick inner folds, licking and sucking greedily at her clit while she ground down harder, moaning his name in that breathy, identical voice. The pleasure was overwhelming, their bodies moving in perfect sync around him, but something felt wrong. His muscles started to burn. His arms and legs grew heavier with every thrust, like invisible weights were being strapped to them.
He tried to push through it, gripping Mira's hips tighter and driving into her even faster, but the fatigue hit like a truck. A sharp headache bloomed behind his eyes, pounding in time with his racing heart.
Then the notification slammed into his vision, red and urgent.

____
Noah's eyes widened in panic even as Mira clenched around him and Myra cried out above his face. The warm glow from the optimization skill vanished instantly. His cock stayed hard for a few more frantic seconds, but the overwhelming wave of exhaustion crashed over him like a tidal wave. His thrusts slowed, his tongue grew sluggish against Myra's dripping folds.
He was losing consciousness fast.
In one last desperate burst of strength, Noah shoved Myra off his face, gasping for air. His vision blurred as he looked up at Mira still impaled on his cock, riding him with wild abandon. For a split second, something shifted in his sight. Horns curled from her forehead, dark leathery wings unfurled slightly behind her back, and a long, sinuous tail swayed behind her. The same demonic features flickered over Myra as she caught herself on the couch, eyes glowing with something far more dangerous than simple lust.
Then everything went black.
Noah collapsed back against the cushions, unconscious before his head fully hit the fabric.

The private room door remained closed far longer than expected.
Outside in the dimly lit hallway, Madam stood with her arms crossed, tapping her foot impatiently. Lena shifted nervously beside her, checking the ornate clock on the wall for the third time.
"It's been forty-five minutes already," Lena said, voice laced with concern. "They should have been done by now. Thirty minutes max, you told them. Should we check on them?"
Madam's eyes narrowed, a flicker of irritation crossing her elegant features. "Those two never know when to stop. If they've drained him completely…" She exhaled sharply, already turning toward the door. "Fine. Let's go in."
Lena nodded and reached for the handle.
The moment the door swung open, the scene inside hit them like a slap.
Both twins had fully shifted into their origin forms.
Mira's leathery wings were half-spread, sharp horns gleaming under the dim lights, and her tail lashed violently behind her. She was still straddling Noah's unconscious body, fangs bared as she leaned down toward his exposed throat, claws extended, clearly moments away from feeding. Myra crouched on the other side of the couch, her own tail whipping through the air, eyes locked on Noah with predatory hunger. The air in the room crackled with demonic energy, thick and heavy. The playful, teasing atmosphere from earlier had vanished entirely. They looked ready to tear into him and devour every last drop of his life force.
Madam's face twisted with pure, explosive fury.
"NO!" Her voice cracked like a whip through the room.
She moved faster than Lena had ever seen. In one fluid motion, Madam's hand shot out, fingers wrapping tightly around Mira's long, sinuous tail. With a roar of pure rage, she yanked hard and hurled the succubus twin across the room. Mira slammed into the far wall with a sickening thud, wings flaring out instinctively as she hit. Plaster cracked behind her.
The force of the throw was so violent that the thick load of cum Noah had poured deep inside Mira during their frantic fucking splashed out in a messy arc. White streaks splattered across the wall where she impacted, dripping slowly down the surface, while the floor around the couch was already covered in puddles and smears of it from their earlier intense session.
Myra snarled and lunged toward Noah's defenseless form, but Lena was already there, grabbing her by the horns and dragging her backward with surprising strength.
"What the hell do you two think you're doing?!" Madam shouted, her voice trembling with fury as she stalked toward the twins. Her eyes blazed with protective anger. "He is under my protection! You were supposed to test him, not try to eat him alive and shift in front of him like feral animals!"
Mira pushed herself up from the floor, rubbing her tail with a hiss, her demonic features still fully on display, cum still leaking down her thighs. Myra struggled against Lena's grip, tail thrashing wildly.
"He was so close…" Mira panted, voice layered with something darker now. "His energy… It was delicious. We couldn't stop."
"We almost had him," Myra added, licking her lips, eyes still fixed on Noah's sleeping face.
Madam's hand cracked across Mira's cheek in a sharp slap that echoed through the room. "You idiots. He's not some random client you can feed on without consequences. If he wakes up remembering any of this—"
She glanced down at Noah's limp, half-naked body, his pants still undone, cock softening against his thigh, the evidence of their wild session everywhere. The system notifications had long since faded from his vision, but the exhaustion was written all over him.
"Get them out of here," Madam ordered Lena coldly. "Lock them in the containment room until they calm down and shift back. I'll deal with them later."
Lena nodded quickly, already dragging a protesting Myra toward the door while Mira followed with a sulky glare, wings folding reluctantly against her back, more cum dripping onto the floor with every step.
Madam knelt beside Noah, gently pulling his pants back up and covering him with a nearby throw blanket. Her expression softened just a fraction as she brushed damp hair from his forehead, though the anger still simmered beneath the surface.
"Poor boy… you really are something else," she murmured. "Sleep now. We'll talk when you wake up."
The last thing Noah heard in his deep, forced sleep was the faint click of the door closing, leaving him alone in the quiet, cum-splattered room.
