Kayla is napping in bed, when her underwear is slowly pulled down. It's beneath her cheeks and an invisible being begins moving towards her butthole and begins to push its way in. This startles her awake and she tries to move away but her arms are pinned by her side and she is held in place. She feels something touching her butthole and cries out, begging for it to stop. She protests but it pushes its way in, further and further until it feels like it is all the way into her belly. Her body begins rocking as it thrusts inside behind her. She cries out and beg but it just thrusts even harder...

Kayla is napping in bed, when her underwear is slowly pulled down. It's beneath her cheeks and an invisible being begins moving towards her butthole and begins to push its way in. This startles her awake and she tries to move away but her arms are pinned by her side and she is held in place. She feels something touching her butthole and cries out, begging for it to stop. She protests but it pushes its way in, further and further until it feels like it is all the way into her belly. Her body begins rocking as it thrusts inside behind her. She cries out and beg but it just thrusts even harder causing it to hurt more, like her butt is tearing. She feels something sprayed deep inside her butt and almost all the way up into her intestines. It pulls out quickly all at once causing her to go right out.

Whatever has sprayed inside her butt has taken over her body, put her underwear back on, and flipped her onto her back. She hasn't come back to yet but her belly is moving slightly. The stuff inside her butt is making its way up to her intestines and up into her belly. Her belly continues to move and roll and then starts expanding. Her belly stays expanded and keeps moving. The new thing inside of her is ready to burst out.

This causes Kayla to come to. Her belly has stopped moving but is still fully expanded outwards. Her butt and belly are both in pain. She tries to move but her body is locked in place and then notices that her belly is big. Confused, she touches it which causes it to start to move again. Inside her something is moving and trying to burst out. She tries to get up and fails and her arms are pulled above her head and pinned. Stuck, she stares helplessly down at her large belly. Kayla begs and pleads but her belly keeps expanding and her bellybutton grows wider, something behind it ready to burst through. Her belly moves more now and she cries out, it is pushing outward and she can feel it tearing. She cries out as it bursts open.
