Right

"Hasn't failed me yet..." Anna mumbled to herself, crawling as fast as her body could manage on the metallic pathway. She turned the corner and discovered an exit to the vent that led to a long vertical shaft with a fan at the top and bottom, each covered by a metallic grate. Up near the top was another vent opening that seemed to have white light streaming out of it. Above her head was the beginning of an old dusty ladder that led up to it. The phone in her hand began to talk again.

"Get up there! Fast! I will do what I can to help!" It called out. She went to place the shorts and panties into her pocket...and only brushed her bare thighs. "...right." She said with disappointment. Where was she going to put these things?! She was able to stuff the phone into her other bra cup, but that left nowhere for the other items. "...guess this'll have to do..."

"Where the fuck..." Emily began, looking down to see no trace of anyone below. Turning to look upward though...she saw distinct shape of Anna's ass.

Practically flipping onto the first run, Emily began to fly upward, her athletic body far more in shape than Anna's. She quickly reached Anna's legs and grabbed onto her right shoe.

"Got you, you fucking pervert! Hand over my shit right now..." Before she could even finish, a hard pain rocketed through Anna's butt. "...or I will pull that cute butt right off the wall!"

By this point, Emily's one-piece uniform had begun to lift upward as well, revealing the lack of anything beneath. Sweat began to pool on Anna's forehead as she considered her options. Say no and try to escape? Try to reason? From the phone inside her bra, Anna could hear a muffled voice saying "...hang...on..."
