After Midnight (futa/female, underage, excessive size/cum, public)

Hey, folks. It's been really hard for me to write lately. I'd really like to add to my existing stories, and I am attempting to do so(slowly), but I have almost no inspiration. A while ago, I found the picture attached to this post, thought of a story to go with it, and decided to write it down, hoping it would get me out of my funk. Long story short: it didn't. Since then, I worked on it about 6 times, writing a paragraph or two each. Today, I decided to power through it to an acceptable stopping point so I could get it up here and hopefully get some feedback. As a result, I'm not sure if I'm as satisfied with it as I could be, but I don't think I would have gotten much done otherwise. I do have some plans for it, but I'm not confident that I'll be able to put them on paper. I WANT to, I'm just not sure if I'll get to it anytime soon.

Anyway, here's After Midnight:

A bell dinged, and the door slid open. Darla glanced around nervously as her mother led her across the platform and into the subway car. Seeing only a single woman seated inside, the 13-year-old let out a relieved breath. This morning, all the cars were crowded with weird people, and Darla didn’t like crowds one bit. When she grew up, she would move somewhere with no subways, so she wouldn’t have to ride one ever again.

She heard a familiar buzz, and looked back to her mother just as the tall woman pulled her cell phone out of her suit pocket. She peered down her nose critically at the caller ID display, like she always did, and put the phone to her ear.

“This is an important call, so don’t bother me until it’s over.” She grunted at Darla, and shifted her attention to whomever was on the other end of the line.

Darla frowned. Mommy was always in an important call. Even today! Mommy had taken her to the law firm for take-your-daughter-to-work day, sat her in the break room with a couple of magazines, and shut herself in her office. She had ended up working really late, longer than anyone else in the office- it was almost one o’clock at night now.

The subway began to move, and Darla’s mother reached up with one hand to grab a support handle. Darla wished she could reach them.

One stop went by, and then another. At one point, Darla’s mother took a packet of papers from her briefcase and began to argue with the mystery important person about them. Darla tried to follow the conversation, but it was too confusing.

Increasingly bored, the girl looked at her surroundings. Her eyes paused on various colorful advertisements before settling on the other woman in the car. She had been so quiet, Darla had forgotten about her...

The girl tilted her head. Now that she really looked at the woman, she noticed how beautiful she was. She was muscular but not overly so, and her skin was sleek and smooth. A medium-length crop of blond hair, damp with sweat or water, hung loosely across her ears
