She uses her head

Nicole spent the next few minutes experimenting with the puzzle. She would need to keep both buttons pressed at all times to keep the key exposed.

The buttons were too high for her to reach with her feet, although the voice and her other anonymous viewers were no doubt thrilled about the flashes of her naked ass these attempts provided them.

She then tried holding one button with a hand and the other with her head, leaving an arm free to maneuver in the box, but she found that she could not contort her body to wrap around and grab the key, though again, she realized that trying to keep her breasts contained in their lacy prison was probably wildly entertaining for her audience.

Unable to see another way, Nicole placed one hand on each of the buttons, and bent over slightly to place her head in the box. She would have to use her mouth.

She first tried to maneuver her head around the side of the rubber cock, but found the box too narrow. Her options exhausted, she wrapped her full lips around the shaft, moved her head down its length, and found, to her surprise and frustration, the key was STILL out of reach, although just barely.

"Looks like our future cocksleeve needs a little practice" Chimed the voice.

Nicole begrudgingly took the hint, pulled back, and reconsidered her approach. Sticking her tongue out, she dived down the cock again. This time she could touch it, but not enough to manipulate it. She needed more room.

Suddenly it hit her. She had seen porn before. She needed to take the cock down her throat for this to work. Not a lot, but just enough. Almost eagerly, she set to work moving her lips up and down the length of the simulated penis building up lubrication for her deep dive, unaware of how whoreish she looked or how enticingly her tits bobbed in her bra as she did so.

Eventually, she felt confident in her preparation and took a deep breath, then plunged her head down on the cock, managing to envelop the keyring and briefly bring it forward, before a loud "GRK" signaling the presence of her gag reflex required her to return to the surface for air. But her strategy had worked, the key had moved forward, so she set back to work.

Another ten minutes of sucking, some running mascara and some near misses of vomit later, Nicole held the key in her hand. Near euphoric from the lack of oxygen during her ordeal and the sheer effort it had taken, she was secretly proud of how well she had taken that cock.

"Yeah I've got nothing", the voice said. "That was fucking hot. I'm gonna need a minute "

Nicole savoured the silence, cleaned the spit, snot and mascara from her body as best she could, caught her breath, and prepared to move on.
