Charlie rubs her stomach, as it gurgles. She whines and speaks apologetically "Sorry, but I'm not even going to try and hold this in." She then lets out a fart.

BRRPT~!

The fart is fairly short in length(1 1/2 seconds), though it is loud and rumbling. The fart quickly moves up and expands, after leaving Charlie's butt.

Charlie speaks up "That wasn't very relieving... I still have like... 16 farts left in the tank, provably all bigger than that one..."
