>Twilight's mouth was dry.
>She was on the outskirts of town, by a small wagon stop. Not a place many people went to willingly.
>Not a place she'd ever imagined herself going
>Especially not to this particular area of the stop
>The bathroom
>She slowly put a hoof on the door and opened it
>She had always wanted a foal.
>A little colt or filly to take care of, for her very own
>But she could never find the right guy
>No matter how hard she tried, there was never any stallion she really wanted to be her child's father
>Now she was going to take matters into her own hands
>She was in heat. She had been for a few days.
>And it was making her desire for a foal unbearable
>She took a few weak steps into the bathroom, building her resolve
>It was the best way for her to do this.
>She searched through the stalls until she found the one she wanted
>There, in the middle of the divider, was a large, round hole.
>Meekly, Twilight went inside and shut the door.

>She could feel herself getting wetter
>Was she-
>Was she really doing this?
>Well
>Apparently she was
>Twilight slowly turned herself around, pressing her pussy up against the hole
>She took shallow breaths, still nervous
>Now all she had to do was wait.
>Four minutes later, she heard the door to the bathroom open
>This was it
>Her whole body was tense with fear and anticipation
>She would finally be a mother
>Hopefully
>Well, assuming this Stallion used the stall next to her.
>She heard him approach
>He was definitely near her stall
>Please, c'mon...
>To Twilight's relief (well, that wasn't really the right word, since she was still utterly nervous, but it would have to do), she heard the Stall door next to her swing open
>"Wha- Celestia!"
>An unfamiliar voice rang through the bathroom
>Twilight's face turned an even darker shade of red
>She heard the Stallion next to her shuffling about. A few seconds later, she felt something press against her walls
>Twilight bit her lip as the stranger next to her took her virginity
>She continued to bite her lip, desperately trying not to make noise, as he continued to thrust
>Twilight came. A few seconds later, so did he
>His fertile seed flooded her womb
>Yes! Yes! Yes!
>She would finally be a mom!
>...Well, she would, but that Stallion would be able to tell that
>After all, he was the only one to visit the gloryhole
>What if he figured out it was hers?
>What if he wanted to take care of the kid with her?
>What if he was horrible?
>That wouldn't do
>Maybe...
>Maybe if she stayed for a few more stallions
>So it was untraceable

>Twilight stayed, pressed up against the stall wall, seed slowly leaking out of her, as the Stallion that had just fucked her walked out of the room and back to his friends at the bar attached to the stop
>Most of them didn't believe him when he said that there was a mare in the ol' Gloryhole. Even less believed him when he said she smelled like heat.
>He insisted. They called him a bullshitter. He insisted again.
>Finally, one of his buddies decided to check it out
>Twilight heard the door open again
>This time, the pony walked swiftly to the stall next to her
>"Oh- He wasn't a liar!"
>Twilight felt another stallion (another stranger) inside her
>This time, she moved as well, slowly moving her hips back and forth against the wall
>Maybe this would be the father of her foal...
>Just the thought got her wet
>Almost more than the sex
>This stallion lasted a bit longer. He rutted Twilight for a solid minute after she came until he too flooded her.
>Twilight smiled
>It felt good to be so filled
>So that was two. She figured that three would be safe enough, and she (and her newly-made foal) could get back to her life
>Meanwhile, the stranger in the stall next to her left, returning to the bar
>"He's not lyin'! There's a real mare!"
>Slowly, two ponies stood up from their place at the bar.
>"No way. I gotta go see this."
>The two made their way to the bathroom.
>Twilight tensed up again. C'mon... Last one...
>The first stallion entered the stall. Shortly afterward, he entered her.
>"He wasn't a liar!"
>Twilight froze
>Who- Who was he talking about?
>The horrible realization came over her
>Oh god
>One of the ponies who had- who had rutted her
>He had told others
>As the stranger came inside of her, she started to worry in earnest
>She had heard two ponies walk in
>So where was the-
>Her question was quickly answered as another pony became to thrust inside of her
>Oh god
>She couldn't leave
>They'd see who she was if she left
>She just had to wait it out.
>After this one, she'd leave. Leave with her foal.
>Who was the whole reason she came here in the first place
>Unfortunately for her, the first pony galloped back to the bar
>After three ponies, the entire place believed her
>And the patrons quickly formed a line

>Twilight tried to not panic as she heard ponies shuffle in
>This-
>This really wasn't that bad
>More potential fathers
>Nothing more
>But they just kept coming and coming!
>She felt semen drip out of her in earnest, whipped into a frothy mess by the other Stallions desperately thrusting into her
>This slowly dripped down her, until the entire back half of her body was messy
>At least twelve stallions had came inside her
>She herself had climaxed at least ten times, each more intense than the last
>She couldn't handle this any more
>The sensations were too intense
>But she couldn't just leave!
>And she doubted these stallions were going to just leave if she pulled back
>She would just have to endure it
>And endure it she did
>All four hours of it
>By the end, she could barely walk
>She stumbled out of the bathroom, her legs dripping with the semen of dozens of Stallions, and started the long trot home
>At least she had a foal
>That's all that mattered

>$(GESTATION_PERIOD) months later, Twilight held her foal in her forelegs
>He was a pegasus
>Apparently, his father was as well
>He had her eyes and mane, but his fur was much lighter -- Not purple, but a sky blue
>He was wonderful
>Though...
>Maybe he wanted a sibling?
>Twilight was totally satisfied with how things had turned out
>But the gloryhole seemed a bit inefficient
>Maybe she could put an add in the paper...
