Into the airducts.

With incredible care and precision Felicia had managed to take three screws off the vent. Now if she could just get the fourth one off, her and Peter would be golden.

Meanwhile Peter watched as his partner crotched on the top of a storage shelf pulling screws out of a vent. He had no idea such a thing was possible without superhuman abilities.

"I guess being a thief takes more talent than I thought." Peter whispered to himself.

"What was that Spider," Felicia said. "Are you admiring my ass."

"What? no!" Peter said defensively although his eyes immediately wandered down to her exposed cheeks. "I mean not initially."

Felicia giggled enjoying herself. It seemed as long as no one caught her Black Cat had no problem sneaking through a high security facility starkers. A feeling Peter wished he could share with her. He heard the sound of a door closing outside the storage room and instantly went to covering his junk. However no one came in.

"Relax," Felicia laughed. "A handful of people have access to this room and they only use it for storage at the beginning and end of their shifts."

"How do you get all this information?" Peter asked dropping his hands.

"All in good time my apprentice," She joked. "But first lets finish this heist." Felicia finally pulled the grate off the vent opening up the path to their first objective. They had to crawl through these vents to the special lab where the Alkanivorax was being kept. They had a short window before the scientists came to start their experiments with it so they had to hurry.

"Ladies first," Spidey said as he climbed up on the shelf.

"Always the gentleman." Black Cat said feigning gratitude as she climbed inside. "And of course your not just saying that because its part of the plan."

"I would never." Peter said following her in. "This time I do just want to look at your butt."

Peter was being more honest then he realized. As they crawled on their hands and knees, bent over Felicia's ass cheeks were spread out wide. Every minute detail of her posterior was mere inches from Peter's face, giggling every time Cat motioned forward. Pete couldn't help but stare trying to memorize the whole thing in the semi dark area. Eventually they reached their desination which Peter realized when Felicia stopped crawling and he slammed his face right into her soft buns.

"Woah," She squeaked. "Save it for the bedroom spider."

"R-right!" Peter said cringing at how wiped he sounded. "So is this it?"

"Yep," Felicia smirked, pulling off the vent grate and sticking her head into the room. She saw a stark white room with no windows and one entrance. There were a few lab stations housing various scientific equipment she knew nothing about. In the center of the room was cooling unit housing dozens of tube racks all filled with brightly colored liquids. "Clean lab 3. Where Roxxon experiments and stores this chemical of yours."

She focused on the floor and spotted several rows of distortion on the floor every few centimeters.

"They've got detection laser running across the floors just like the scamatics said." Black Cat smirked. "Normaly all I'd need was a few gadgets off my utility belt and a little grace to avoid them." She gentally tapped on her hips where her belt would be, making soft slamming sounds with each hit.

"Sadly, that's not an option." Peter replied.

"Nope," Felicia said trying to hide her excitment. "Fortunately I love to improvise. You ready partner."

"No but you're already going sooooo," Peter said watching Felicia start to lower herself into the room. She had first flipped herself onto her back and began pushing inching through the opening. Peter watched as Black Cat's head, torso, thighs, and ass disappeared and all that was left was her legs are Felicia hung upside down from the back of her knees. She was like a gymnast. A naked gymnast.

"Burrrr, you better be careful Spidey. Theres a draft in here."

Peter rolled his eyes as he too got into position rolling onto his back. This time however he wasn'tinching forward like Felicia he was wall crawling or ceiling crawling to be precise. Peter crawled from the top of the vent to the top of the lab. Finding himself spawled out right in front of Felicia.

"Wow," She said biting her lip, "was this what the crawl over here was like for you?"

"Alright, alright" Peter said nervously. "Let's just do this already. Try not to miss the landing."

"Don't insult me." She said right before swinging herself back and then forward with incredible ****. It pulled her off the grate, and for a few seconds, Black Cat was in the air until she was directly below Peter's bare back.

With speed that even empressed Spiderman, Felicia grabbed onto Peter, wrapping her arms around his neck and legs around his waist. She pressed her massive rack into his back just as.the full momentum of her leap was transfered into Peter's body. It did little to move the superhuman, yet Peter still found himself sticking there motionless.

"What would you call this? It's not exactly cowgirl style." Felicia whispered into his ear.

"Hard to say." Peter smiled as he began crawling across the ceiling. "Expecially when you consider we're probably the only two people who could do this.

"Hmm," Felicia pondered. "Then how about... The Wall Crawler?"

"Sorry baby that's trademarked." Spidey joked. "Maybe, The Clinging Cat?"

"Me-ow," Felicia said affirmatively. "Always so generous."

As the bantered Peter made it to the center of the room sticking right above the chemical cooler.

"Alright we're in position." Peter said.

"Here comes the fun part." Felicia replied as she began to reposition herself. Tightening her grip with her legs, Black Cat pulled her arms away from Peter's chest allowing herself to hang upside down. "You know maybe should just call it the upside down cowgirl." She then began inching her way forward until her big butt was sat right on his shoulder blades.

"I don't think it does it justice," Peter moaned. He felt immense pleasure as Felicia rubbed her ass against him. Despite the serious circumstances, he couldn't help but get hard. Regardless he continued the mission. Spidey places a lot of grip on his foot before removing his hands from the ceiling. His leg muscles tightened as even with his superhuman strength holding too people upside down with just his feet was a heavy load. Peter grabbed Felicia by the thighs as she untangled her legs. Trusting entirely in him to hold her up.

"You good?" Felicia asked.

"Hey," Peter replied. "Try not to be too impressed ok." From there Peter did two things. One he began to straighten up going from crotching on the ceiling to standing on it, and two he lowered his grip on Felicia's body from her thighs to her knees then calfs, then ankles. When he was done Peter was hanging from the ceiling by his toes holding Felicia so she was so close to the cooler she could breathe on it.

"Ok," Peter said strained, "your turn."

Felicia didn't reply she simply got to work. Arcing her back to get a better view, she examined the cooling unit for a second examining the small tumbler lock on its door. Felicia's eyes narrowed as she focused on the small mechanism, her fingers instinctively reaching for the lock's surface. With a delicate touch, she began to manipulate the pins, she had no tools or gadgets in her naked state, so she had to determine the combination from sound alone. The faint clicking and scraping echoed through the air as she worked, her hands moving with a precision that bordered on artistry.

As she worked, Peter's grip on her ankles remained firm, his toes digging deeper into the ceiling to compensate for the slight shifts in her weight. He could feel the tension in her body, the concentration radiating from her like a palpable ****.

With a final, delicate tweak of her fingers, the lock disengaged, emitting a soft click that seemed almost deafening in the stillness of the laboratory. The sound was immediately followed by a faint hiss of equalizing pressure, and then the door of the cooling unit swung open, its hinges creaking softly.

Felicia's hands moved with swift precision, reaching into the depths of the unit and withdrawing a small, unassuming vial filled with a viscous, amber liquid. The label on the vial read "Alkanivorax - High Concentration" in bold, black letters. She had no pockets, so Felicia was **** to hold the vial in her mouth, biting down gently to keep it in place. It was dangerous as the smallest crack was fill her mouth with the deadly agent, but like with all things, Felicia loved the danger. The Black Cat gave Peter a thumbs up signaling for him to pull her back up. Now they just had to get back into the ventilation system and no one would be the wiser.
