An Unexpected Encounter

Part 2

Hello Hello!

This is the second part of the story Late Night Encounter.

I would highly suggest reading that for context, so you're not completely lost with this story, but it can be a standalone.

I am going to hell for writing this.

TW: Birth, labor

Mabel walked down the beach, her hand over her swollen belly. It was mid afternoon the next day, and Mabel was exhausted. Last night had drained her energy and once she got home, she had spent all night asleep. Luckily, Dipper was busy reuniting with Wendy, so her several hour absence when she had gone into the cave went unnoticed.

Her belly, however, was harder to hide than she expected.

The swelling hadn't increased, but it was so hot out that wearing clothes that were thick and baggy enough to hide it was very uncomfortable. Luckily, Greasy's diner had gotten air conditioning, and she was able to stuff her face all morning. Despite eating the entire contents of the fridge the afternoon before, and then eating at Greasy's all morning, her hunger had barely subsided. She was about to order her 7th plate of food, but she had gotten a strange cramping feeling, so she had decided to head back to the cave.

As she walked, the cramping had been getting steadily more intense, to the point where she began to get concerned. It was like a shifting inside of her, as if the eggs were shaking.

She could see the cave in the distance, but a nagging feeling told her she needed to speed up. She began to walk faster, and then jogged, but almost immediately she felt a shift in her belly and the cramping grew far too intense.

She crumpled forward, clutching her stomach as she fell to her knees. She muttered a long string of expletives under her breath as she felt some of the most intense cramping she'd ever felt in her life. It wasn't painful so much as it was foreign, something she had never felt before. She couldn't bite back a moan as she got to her feet and began to stumble to the mouth of the cave.

"Oh god." She yelped, falling to her knees again. She was mere feet away from the cave, but she could feel something shifting. She put her hands between her legs and gasped. She had put on a skirt, and as soon as she touched her underwear, her heart started racing. It was soaked through, and not with her arousal. It was thicker than she was used to, and a little sticky, just like what the tentacles were coated in. She got back onto her feet and just barely managed to reach the cave before she felt an egg slip out of her stomach and begin to slip through her intestine. She screamed and fell to her knees, the pressure making her body tense up. She squeezed her thighs together, trying to keep herself from squirting as it worked its way through her body.

It got farther and farther, until suddenly, it stopped.

Mabel gasped and shifted her weight off her knees, instead laying against the cave wall. She rocked her hips from side to side, but the egg didn't budge an inch. It stayed right where it was, and she groaned in frustration. Just to test, she took a breath and clenched her muscles, pushing gently. The egg moved, and she slapped her hand to her mouth to hide her shriek as she squirted through her panties.

"F-fuck." She muttered. She tried to use the wall to stand up, but the pressure was too much. "Gotta get this one out first, I guess." She pushed again, harder this time, and she could feel it moving as it neared her asshole. She could feel the shifting with her hand as she clutched her stomach. "Ah, oh god, ohhhh, fuckkkk." She grit her teeth and pushed, the egg pressed against her tight ring of muscle. It wasn't moving.
