The house was advertised as a place that hosted "safe trips," sort of like for certain hallucinogenic experiences, but for transformation instead. They thought it sounded fun. There had been all sorts of videos of people transforming, interviews that made it sound satisfying, almost transcendental. There were some who seemed to regret it, and concerns that it might not be a reversible process, but proponents laughed it off as busybodies just getting in the way of a good time.
Their host, a reedy, nerdy looking guy, gently placed a tab on each of their tongues and told them to hold it there while it dissolved. They looked around at each other grinning with excitement. Next he told them to remove their clothes...this brought the mood down a bit, but he explained that they probably didn't want their shirts and pants all shredded as they grew, which made sense. None of them were really in any position to protest, with their tongues occupied and peer pressure kicking in...so one by one, they stripped. Their bodies tingled, and they giggled and pointed at each other as their noses turned up and expanded into pig snouts. They slowly ballooned in size as wiry hair spread across their forms, and they had to agree that the sensations were incredible. As pairs of teats sprouted along their torsos and their toes merged into hooves, their host once again had a suggestion: they should get down on all fours and feel what it's like to become truly piglike...they grunted in assent and dropped to all fours, looking from one to another in strange satisfaction, oblivious to their host quietly watching from behind...and oblivious to how they might feel in the morning, when they still hadn't changed back...
