Version: 1

Spark lazed on her side, hoof on her cheek as she watched the unfolding drama below.

One of her micro friends, Swift, a pegasus, had invited her to spend a day with one of his other friends. This other pony, a strong earth pony named so creatively Smalls, owned a fair sized house on the edge of town.

Spark loved micros and was always eager to meet more. However, the situation had quickly soured when Smalls and Swift wanted to go swimming. But the pool in Smalls' backyard was currently empty. Winter was finally wrapped up and the earth pony had just now learned his pump was broken. An argument of how to solve this serious problem erupted.

Sparks wouldn't have minded watching a pair of cute little micros bicker if it weren't for a few insulting details:

One, she had come here expecting to take part in whatever activity and make a new micro friend.

Two, neither pony had even considered the pool could barely fit two of her hooves when they could easily have gone to the lake or the beach so she could swim with them.

And three, neither pony was asking her for input. There were a number of ways she could have helped in this situation. From suggesting they do something else to just letting her run home to get a bucket of water that would easily fill the pool for them.

But no. While her belly formed a literal wall beside the house, the two were somehow able to completely ignore her as they went back and forth whether to call a repairman or just buy a new pump.

At first Spark thought it was amusing. Then she got bored. Then she started to get frustrated. Finally, she was starting to get angry. More than an hour had passed and the two idiots still hadn't figured it out.

Nopony likes having their time wasted. And with all this talk of water she now had to pee too.

She could have just cut into the conversation, but now she didn't feel like spending time with her friends. Now she felt they needed to be taught a little lesson. Following that decision, her eyes were drawn to the empty pool and an evil idea came to her.

"Maybe we could just order the water," Smalls suggested. "There is a service of water trucks I could--"

"Well boys," Sparks cut in with her naturally much louder giant voice. "This has been fun, but I've got to get home soon." The huge mare began to stand, pulling her hooves across the grass and leaving ugly brown dirt grooves.

"Hey, watch the grass!" Smalls protested.

"Wait, you can't leave," Swift objected. "We haven't gotten to do anything yet."

"Yeah that's why I think I should go," Sparks mumbled, trying to hide her anger. For a moment. "I've got more important things to do then listen to you two ramble on."

Swift cringed, suddenly realizing he hadn't said a word to Sparks in... a while. "Oh, sorry."

The mare made a dramatic yawn and tapped her muzzle before giving the tiny pair a scowl. "You will be sorry in a moment. Inviting a girl over and making her sit in the hot sun all day?" She snorted.

Smalls stepped back, fear in his eyes. He didn't know her and she was a macro. This could get dangerous. "W-what are you going to do to us?"

She rolled her eyes. "Nothing. I just need some place to pee before I go cool off. Luckily, you have just the accommodations for me," she grinned evilly.

Smalls was confused. "I don't have a toilet in your size."

"Sure you do. Now if you don't mind, please look away while I do my business." With that, the large mare began to approach the still empty pool.

Smalls was confused as Spark's straddled the pool with her back legs, hanging her tail and backside over the empty concrete lined hole. Then the stallion's eyes widen with terror. "No wait!" he called. But it was too late. Sparks squatted and cast her tail to the side. Her pussy hovering a short distance above the bare pool and with two ponies watching, she let go.

For her it was only a dribble at first as a bit of embarrassment colored her cheeks. But she quickly felt the naughty pleasure rise in her chest. Swift stared as a fountain of yellow almost immediately turned into a waterfall. Smalls sputtered and protested, yet none of his not-words stopped his pool from filling with the golden liquid.

A faint steam wafted through the air. Each breath for the little ponies was tainted by ammonia. The pool level rose and rose, twisting and stirring as the huge mare continued to pee. It was a very long minute before her release began to slow to a drip.

Sparks sighed and stood up, quickly hopping around to see her work. The pool was a little low, but she was empty. Also, the two problem ponies were stunned. With a nod and a hum of satisfaction she began making her way home, a happy sway to her macro hips.

Smalls could only gawk in disgust at the mess as it stilled in his pool. "It's ruined. I'll never swim in it again," he cried.

Swift was silent, eying the urine filled hole with... curiosity...
