((You and your friend Emi are on a camping trip. It would be as simple as that, except that when you first showed up to the campsite, there was already a girl there, alone. She seemed all too eager to join you and Emi on your camping exploits, so you two let her tag along. Exploits are had, smores are eaten, and you call it a night.))
You and Emi are currently sharing a tent, asleep after the events of the night. It's just like any other night spent in the middle of the woods, you in your sleeping bag and Emi in hers. It isn't until you're stirred from your sleep by the sound of grunting, blankets shifting, and the sound of... swallowing?
In the space just next to you, you can only watch as Tabitha has somehow invaded your tent, looks monstrous in her appearance with sharp claws and teeth, and is currently straddling Emi's waist. Instead of the scene looking romantic, you immediately notice the hungry look on Tabitha's face, and the fact her jaw is open at an inhuman size, looking about ready to wrap around Emi.
Tabitha stops her attempt at swallowing your friend when she notices you awake, her mouth closing back to normal size.
"Uh... hey, camp buddy! I was just trying to... eat your friend here, heh~"
