Tar cringed as warm jizz flooded her mouth. This load was thinner than the last, less bitter, almost like a really salty shot of milk that had been left on the counter for a day. She raced to swallow it before any could spill out. It took forever to clean out of her fur.

Usually, they withdrew quickly after they had finished. This one lingered a little longer, content to let Tar suckle gently on the tip until the very final drops of ejaculate had been washed away. She felt it tug softly backwards, and opened her mouth. The shrinking cock withdrew from the gloryhole. A male voice grunted something that might have been 'thank,' followed by hooves on tiles and a stall door swinging open and shut.

She wiped her mouth with a hoof, and looked around the bathroom stall. Same as ever. Stupid graffiti. Out of toilet paper. Filthy toilet. Piss-stained floor. Hole in the wall...

She jumped as a dick suddenly intruded through the wall, and scowled with recognition. It was her pervert math teacher's cock, the familiar pattern of mottled pink on the side a dead giveaway. He must spend half his wages on the gloryhole, she thought. Opening her mouth, she moved forward to take it in, and cringed at the unusual musky-honey taste. He'd obviously just finished fucking another student...

The teacher finished quickly, his smaller load still enough to fill her mouth, and withdrew to be replaced by another dick. Tar continued to suck cocks, small ones and long ones, jock dicks and nerd dicks, every horny little fuck-up in the school with enough pocket change to fill the admission fare. Her withers ached from holding herself in this position, and her tongue was completely numb. She felt a mixture of boredom and disgust as a random shaft coated her teeth, gums and tongue with the thickest load yet. In this tiny place, she couldn't even tell what time it was. It might not even be second period yet...

After licking the ropey jizz clean of the cock, he withdrew, and was not replaced. There was an insistent knock at the stall door. Tar slid the lock, and opened up. Petunia and Blueberry glared down at her.

"H-hey," said Tar, nervous and hopeful. "Are - are we finished for the day?"

Blueberry rolled her eyes, and Petunia laughed derisively. "'Are we finished for the day?'" mocked Petunia, "As if! Pig. Idiot."

"We wanted to say you're taking too long," said Blueberry. "They're not finishing fast enough. If you don't stop slacking, you're gonna have to miss lunch."

Tar felt an icy pang of rejection in her gut. "I'm trying my best, guys, I don't know how to do it any better..."

"Well, maybe some dumb coal-colored slut should have thought about that before she threw up all over my best friend's six-hundred bit prom dress, huh?"

"I - I'm..." Tar cringed, and looked down. "I'm sorry..."

"Relax, idiot," said Blueberry. "The next guy is paying triple. He's got a weird request, but you'll be okay. As long as you remember to swallow..."

Tar nodded, eager to prove herself useful. "Of c-course!"

The mares rolled their eyes and shut the stall door. Bits changed hooves, and a cock slipped through the hole. This one wasn't even hard yet. Tar sighed. It would take a while...

She wrapped her lips around it and a second later her mouth filled with hot, salty piss. She froze, unable to move, unable to spit it out, unable to drink it down. The stallion cut his flow off before the pressure forced it out of his mouth, but he was clearly waiting.

"As long as you remember to swallow..."

The piss, and her dignity, slipped down Tar's throat. She heard a sigh and the flow continued. This time she was faster, drinking down the musky liquid, feeling conflicted and worthless. She'd already swallowed cum, and that didn't taste any better. It probably tasted worse.

But then, every slut in Canterlot High had tasted cum at some point. Not even the skankiest, lowliest, most desperate-for-attention whore would drink a stallion's piss. That wouldn't make you a slut. It would make her a urinal.

She closed her eyes in shame as she drank the flow of brackish, yellow liquid directly from the source. Once the piss had tapered off, she kept her mouth there, expecting him to withdraw. He didn't. Instead, she felt the tell-tale twitch of a cock beginning to harden.

It was going to be a long day indeed...
