Try to put the plug in inconspicuously

(Chapter originally by Phantom Pen on writing.com)

I can do this. Makoto told herself. I just... need to position it, and sit. And try to live down the humiliation.

Makoto went to work preparing the plug for its perverse purpose, keeping her hands hidden inside the bag to avoid anybody seeing exactly what she was up to. The bottle of lubricant opened easily and eased its contents out into Makoto's hands and the plug she held. The substance felt unlike anything Makoto had dealt with before. It was slick, oily, and thicker than she had expected. Stranger still, her palms began to tingle slightly as she worked the lube across the entire surface of the plug; the sensation wasn't unpleasant, but certainly not what she'd been prepared for.

The bottle's contents ran out in short order, and Makoto knew there was no more delaying it. It was time to try and do what the letter said. Makoto looked around the train car once more to see if anybody was watching her, and thankfully the people scattered throughout the car didn't seem to be paying her any mind.

Makoto quickly withdrew the glistening plug from the bag and lifted her hips off her seat. The faster she did it, the less likely she was to be noticed, and this wasn't something she wanted to try explaining. Her trembling hand maneuvered the plug underneath her backside, blindly trying to position herself for the swiftest penetration possible.

Unable to check her aim and her hand struggling to stay still, Makoto lowered herself down. The moment her anus touched the tip of the plug, however, her body tensed and a hiss of surprise escaped her lips. Even trying to mentally prepare herself hadn't been enough to truly prepare the embarrassed girl for what she was doing.

Makoto caught motion out of the corner of her eye, and it looked like someone was looking her way to see what the noise had been about. With the fear of being seen in her scandalous position motivating her, Makoto **** herself to sit, hitting the seat with a soft thud and impaling herself on the lubed plug. She couldn't help but gasp as the oiled plug was introduced to its new home, and her cheeks burned with shame as she scanned the car once again.
