Sunset once again felt the pressure build in the colon. A visit to the mare’s room should have been made before this game. Nonetheless, she finally had dialed in her accuracy at tossing the darts. Oh!! Her intestines twinged again. All that tossing technique would do her no good if she couldn’t keep her eyes on the prize. She tensed her asshole to keep it all in. Her lower colon was filled solid: any more being delivered there would push the older muck out of the other end whether she liked it or not.
 
Still, there was a game to play and stuffies to win. Too bad she couldn’t focus. If only that were a fart waiting for its way out. She knew better. Leaning forward was just what her insides craved. The tip of her turd pushed its way out. Sunset quickly clenched back up, but she could feel that some small part of it had released in her panties. More urgently, she wasn’t fully clenched: her sphincter kept pulsing between fully closed and slightly relaxed. The damage was already done and nature was going to have its way.
 
“In for a bit, in for a pounding, and out of my ponut,” Sunset thought as she leaned forward to relax, instinctively lifting her foot for balance. She’d have to walk around the park in pooped pants either way, so she may as well get a prize to show for her stains.
 
Unexpectedly, no further scat came (at least for the moment). Instead, a slow trickle of urine slowly soaked her panties and dribbled down her leg. One of the drops fell straight from her crotch onto the back of her hamstring. Its splash tensed her up just enough to release the log. Sunny silently moaned in ecstasy as her butthole relaxed. The feeling of poop rushing past its ridges was heavenly. She had long since forgotten about the presence of Spike and the bored caricature artist across the alley. Had she noticed, she would have seen Spike equally oblivious in his own world and the artist sketching the scene.
 
Back in the present, she felt the squish of the turd pushing its way between her cheeks. The unexpected stimulation coaxed her bladder into emptying itself the rest of the way with a satisfying hiss.
 
Sunset paused to take a few breaths. Her nerve endings no longer had urgent distractions from the game. Almost certainly, there was more poop to deposit, but that wouldn’t be in formation for deployment for at least another five minutes. Time to take advantage of the minutes of focused relaxation. The subtle weight shift from inside her abdomen to below her tail gave her just that much more leaning power as she threw the dart.
 
POP!!
 
Big smiles all around as the last bits of urine wrenched their way out of Sunset’s panties and down her legs. Victory was won, but at what cost?
