Sinister's underground lab was a labyrinth of steel and shadows, the air thick with the acrid scent of chemicals and the hum of advanced machinery. Rogue, the super-powered southern belle of the X-Men, and Harley Quinn, the cupid of crime, moved silently through the dimly lit corridors, their senses heightened and their nerves on edge. They had been tracking Mr. Sinister for weeks, following a trail of genetic experiments and evil plots that had led them to this secret laboratory just outside St. Louis.
As they crept into the lab, Harley could barely contain her excitement. Her signature pigtails bobbed with each step, and she glanced at Rogue with a wicked grin. "Ready to bust up some bad science, Roguey?"
Rogue nodded, smirking slightly. "Let's find Sinister and put an end to this, ah've had just about enough of crawling through abandoned buildings for one lifetime."
They crept deeper into the facility, their footsteps echoing softly against the metal floors. Sinister's lab was a maze of high-tech equipment and glowing vials, each containing unknown substances that pulsed with an eerie light. As a former Victorian eugenicist who had been enhanced by Apocalypse himself, Sinister was as deadly and unpredictable as his own work.
As the pair turned a corner, they found what they were looking for--a large, reinforced door marked with biohazard symbols.
"This has to be it," Harley whispered, her eyes gleaming with anticipation. She pulled out a set of lock picks, and within moments, the door swung open with a hiss.
Inside, the lab was a chaotic jumble of scientific equipment, computers, and containment units. In the centre of the room stood a massive cylindrical tank filled with a swirling, glowing liquid. Rogue's eyes narrowed as she spotted several vials labelled with strange symbols. She didn't catch the words "Bimbo Virus" below them.
"Looks like we found Sinister's latest experiment," Rogue muttered, her voice tinged with disgust. "Shame that swamp-rat's already gone. Let's sort this place out and take the evidence back, maybe the Justice League will be interested."
Harley nodded, already swinging her mallet at the nearest computer terminal. "You got it, partner!" she shouted, the system exploding in a shower of sparks.
Rogue laughed. She hadn't meant that they should destroy the place, but hanging out with Harley Quinn meant you sometimes had to roll with things. Rogue lifted up a flotation tank full of liquid and, using her mutant strength, threw it through a nearby wall causing debris to fall around them.
As the pair wrecked the lab, alarms blared to life, the room bathed in neon pink flashing lights as the place began to crumble. "Strange choice of colour for an alarm." She thought. "Better we'd not let everything get buried." She grabbed one of the vials, intending to secure it for evidence, but as she did, a large tank in the centre of the room exploded, sending a cloud of the glowing pink liquid into the air.
"Rogue, watch out!" Harley shouted, but it was too late. The mist enveloped them both, the strange substance clinging to their skin and seeping into their bodies.
Rogue gasped, feeling a sudden, overwhelming wave of heat and pleasure surge through her. Her thoughts grew hazy, her body tingling with an unfamiliar sensation. She looked over at Harley and saw the same expression of shock and arousal on her face.
"W-what's happenin' to us?" Rogue managed to gasp, her voice breathy and strained.
Harley, her usual playful demeanour replaced by a look of confusion and lust, shook her head. "I don't know, but it feels... kind of amazing..."
