Justin waddled up behind Laura, and stuck his snout into her wet sex. She squealed in surprise, and tried to move away from him. But her body wouldn't respond, and Laura was frozen in place as Justin started eating her out. He made loud snorts as he licked the sow pussy in front of him. He tasted her juice, smelled her lust, and watched her balls swell.
Justin was gone, all that remained was the boar. Laura sensed this, and knew her last chance to save her humanity was to get as far away from the pig behind her. Or else she'd turn into a mindless sow, a dirty animal just like him. Using all her will power, Laura kicked her hooves back. She was able to knock the Justin-boar over and run. She could get back up to her hind legs, so she ran on all fours, not caring that her teats were waving about as she did. Laura fled down the stairs and into the basement. She locked the door as best she could with hoof-hands.
The boar grunted and bellowed in protest, not understanding that his sow wasn't interested in copulating. Meanwhile, Laura was looking at herself in a piece of shattered glass. She was more pig than human. Her body barreled, big piggy teats hanging obscenely from her stomach and chest. Her curly tail hung above her chubby ass and balls. Her porcine cock held taught against her breasts. Laura felt like crying, but knew she'd probably start snorting like a pig.
So she lay on the floor, exhausted and resigned that her fate was to live life as a pig. Upstairs, Justin-boar was ramming his tusks against the solid oak door to no avail. He was so concerned about getting to Laura, he didn't notice his body changing. He was so in need of a vagina, his body created one. His balls dropped lower in order to make room for his new sow vagina. A sharp sucking sensation pulled the flesh inside, creating a slit. The slit grew deeper and deeper, until it was a fully functioning vagina.
Justin-boar felt his new sex heat up, growing wet and bringing new sensations to his mind. He squealed in excitement and thrusted his ass up. Now he wasn't just focused on rutting, he wanted to be rutted. His pussy was big and wet, in need of a pig cock.
Laura heard Justin's squeals, and her pig mind reacted. The boar sounded in distress, something was wrong. Should Laura go to his aid? Boar or not, Justin was still her boyfriend. If he was in trouble, the right thing to do would be to help him. Laura slowly climbed the stairs, pausing before turning the knob. She could still hear Justin squealing. To her porcine ears, it sounded like he was crying out for help.
Throwing the door open and expecting to see Justin lying there in pain, Laura was instead greeted with the sight of a huge, puffy pig cunt dripping juice onto the hardwood floor. Justin had a vagina, a female vagina. But that wasn't even the worst part. The worst was Laura immediately rammed into his virgin pig slit.
They both cried out as Laura's cock filled Justin's new snatch. She broke through his hymen, and then pressed in so deep her cock touched the end of his slit. Laura pumped in and out, her balls bouncing off Justin's ass the entire time. Her own breasts rubbed Justin's back, leaking milk. It had an effect on him, the milk. His skin soaked it up, and Justin began to grow breasts of his own. Eight small nubs grew first, his piggy nipples. Then flesh rounded and swelled behind them, forming sow teats.
The two pigs came together, seed and wetness spilling out of their organs. The humans were gone, all that was left were hermaphroditic pigs. Laura and Justin ceased to exists, animal lust and desire controlling their minds.
