"You just go Jen, whenever you feel like it." Susan answered as Jen felt a small tingle come over her. Now she would just pee whenever she felt like it.
"Is there any reason I do that?" Jen asked, dreading the answer as Susan spoke up to answer her. "Yeah, you have the digestive system of a worm, so you eat something before pissing and shitting it out behind you." Susan said as Jen gaped at Susan just before the tingling came over her again.
Jenny held her stomach as she felt her insides simplify extremely her digestive system becoming one long tube from her mouth to her ass as Jen groaned from feeling the change. But that felt her with a strange question. "What do I eat?" Jen asked Susan, getting her answer quickly.
"You're basically a human worm Jen, every day when we get to school you find somewhere to start eating the dirt to burrow underground and fertilize it with your shit and piss." Susan said as Jen felt the tingle come over her, signifying the change as Jen knew what she was going to be doing after getting off the bus.
"If I'm a human worm, then why do I have arms and legs, wouldn't they get in the way?" Jen asked Susan, wondering what else had changed, she might as well make the most of it. "Well Jen, when you start to eat dirt your body changes to become more worm like, your arms fuse to your sides. But you don't have legs Jen, you have a tail remember? You should considering that your entire digestive system goes from your mouth to the tip of your tail." Susan answered as Jen felt the changes come over her.
Looking down she watched as her legs fused together and her felt her digestive system expand down them until a hole opened at the bottom of her new tail. From the waist up she was human, on the outside. Deciding not to ask anymore questions Jen remained silent for the rest of the bus trip until the bus came to a stop at the school.
Students started to pile off the bus, Jen being the last one off as she slid off the bus with her new tail. Knowing her new purpose Jen sighed before slithering over on her new tail to a nice green spot of dirt on the school lawn. Looking down at the grass Jen gulped before using her hands to pick up some of the dirt from the ground before sticking it in her mouth and chewing.
As Jen was chewing her arms fell limp to her sides before fusing to her body, leaving Jen limbless as dirt passed through her tube like digestive system. Putting her face the the dirt Jen continued to eat dirt as the dirt she had eaten just moments ago pooped out of her tail end.
After a few minutes Jen had eaten her way underground as she continued tunneling into the dirt. A sigh passed through her head as she resigned herself to doing this for a few hours until she could talk to someone about it.
