Her cell block

Whimpering Katara gingerly waddled down the metal hall with the guards holding her wrists, her thighs were shiny and sticky with her juices

The inside of her thigh highs where darkened and while her skirt covered her embarrassingly red bottom her asshole was still plugged uncomfortably full with what the guard had call a 'small' plug leaving her to waddle as her hole twitched and spasmed

"Uugh~ may I-I...please have a moment to rest" Katara stuttered from being so full, adding please as she felt her warm rear twitch not wanting a repeat

"#negative you are being brought to your cell block, Notice the inspection and maintenance discipline you received counts as your morning set, please continue your respectful behavior and you should have a easy time#"

Katara remembered she'd have to go through this twice a day, she really hoped she could avoid having to get any extra attention

Walking forward they stopped infront of a glowing blue wall, looking up in wonder at the transparent wall her thoughts were interrupted by a guard

"#notice this **** field is both a durable wall and also a conceptual barrier, should you **** your way through you will become temporarily paralyzed and then punished heavily, your personal cell will also have one, blue coloring allows you to pass with a guards permission while red coloration will not allow any passing"

She stayed quiet as her collar made a bing! Noise and the guards pulled her through

A.N. okay first off, last chance to choose any prisoners, these are the ones I've decided on currently
