Terra starts to feel the large jolt of energy dissipate within herself, and feels it all focus on her crotch. Her entire crotch tingled and grew very warm, with most of it focused on her pussy lips, clit, and everything else about it. She quickly began to pant as her pussy soaked itself. As the feeling continued and intensified, she felt a weird pressure. It wasn't like she felt when she really needed to pee, instead it was like her whole body was pushing out in her crotch.
When Terra managed to get enough control of herself and look down at her crotch, she gasped as she saw that her pussy was visibly swelling before her eyes, growing larger between her legs and pushing outwards becoming a bigger bulge. "O-oh!" She gasped as her cunt twitched, more pussy juices flooding onto the floor. It went from her regular sized crotch to something fist sized, able to take much larger insertions and becoming something that would look like a massive bulge in her pants.
Eventually the feeling began to slow down, letting Terra catch her breath.
