Plugg it

"I can plugg my peehole, using the AAA battery in my calculator!", Jessica thought. Proud of herself and her ingenuity, she opened her backpack and extracted the battery. She looked nurvously around to make sure nobody would notice, before she used some spit to wet the battery, lifted her skirt, found her urethra and started pushing it inside. Surprisingly easy, the battery started to slide inside her peephole. There was a little stinging sensation, due to the sensitive skin inside, but it wasn't that bad. To make sure it wouldn't fall out during the day's activities, she pushed it all the way inside, as far as she could get it, using her index finger.

Her mind was solely focused on preventing embarrassment. Whether inserting a battery far inside her could cause problems for her in the near future was far from her mind.
