"Worm digestive system!" one man in the crowd called out.
Jen beamed, turning towards the man. Its eyes were filled with lust at the idea, and it accepted. The crowd quieted down as the changes took place, no outside change evident. Jen felt her insides twist, her intestines straightening out into a straight line, her stomach shifting up into a crop and gizzard. Her pussy mouth also changed, morphing from a vagina to the jawless, pink mouth of a worm. It complimented her cock head nicely.
"Dirt! I need dirt!" it called out, a pile dropping from the ceiling before her. She maneuvered herself on her horse rear-leg "arms" and dug into the dirt, the crowd going wild. It tasted so good; she felt it passing through her drastically simplified digestive tract, a mix of dirt and cum squirting out of both of her butts. Her front butt was actually squirting it back into the dirt pile, which Fucktoy found deliciously disgusting.
"Hey, how about an elephant trunk instead of a dick!" another one called out, curious how the extra length and versatility of the trunk would affect Fucktoy. It accepted immediately, somewhat disgusted by its cock head anyway. The changes soon began, her neck and head turning grey. Wrinkles formed as muscles became noticeable underneath, the trunk bulking up in front of everyone's eyes. Fucktoy noticed a shadow cast over its vision as two finger-like growths grew on the top and bottom of her face, it pushing out into the tentacle-like appendage. A full 8 feet long, it whipped it around, letting out elephant-like cries through its jawless worm mouth.
"I guess he's back to being an it, then!" someone else called out. Fucktoy loved being called "it," its humanity all but gone even in name. As Fucktoy dug back into the dirt pile using its new prehensile elephant trunk head and neck, someone else called out...
