She rode on the city bus' back bumper for quite a few city blocks, before hopping off, spotting a public bathroom and shower nearby. She was already starting to feel the previous days' activities, especially in her rear and jaw, as she stumbled into the thankfully empty facilities, slumping into one of the shower stalls. It took her few minutes of resting before she managed to regain enough strength to finally work out the plug from her mouth, leaving her jaws quite sore and stiff. She was still leaking steady stream of cum from her backside, making her eye the plug with slight distaste, and then positioning it against her tailhole before her weight against it, making it slide into her anus with a quick pop. She spent bit time cleaning up herself, as well pawing at the padlock locking away her pussy behind this chastity shield... and contemplating how to undo all these piercings and locks on her body, before she felt a sudden electrical shock in her pussy! It wasn't much, but it as enough to drive her onto her knees... she must still be in the range of the tracker, if only slightly! Or it was another function of it, as the electric shock was quite weakened. Still, better get further away, she thought as she gathered her still attached chains and started a quick walk out into the dark. Couple more city blocks might do the trick...
