In pain of course

"Nyaaaaahhh!!!" Blake leat out a cat-like screech as a sharp pain in her anus appeared, she thought that a bug had somehow managed to enter her pants.

Blake tries to get rid of it as she applies pressure between her cheeks, but that does not seem to work as she felt another sting.

"Hmmm? you ok there Blake? " Yang asked as she look towards her partner notcing her discomfort

"Ah-no, just some dirt enter my clothes, nothing more" Blake said, she does not want Yang to know that a bug had entered her rear end, she can already imagine the jokes about bugs and bottom.

"Yeah, I get ya, sometimes they manage to enter the scarf and my chest, and don't get me started on the hair-" as Yang went on her talk, Blake tries as best to get rid of whatever is entering her butthole, pinching with her fingers and even squeezing her butt cheeks, all in an attempt to squash the bug regardless of the gross sensation.

Unfortunately for her, the Butt Bug manages to enter more into her entrance, sending more waves of pain onto Blake's rectum.

"Dammit, the little thing is still in there, I gotta get back to Beacon and remove the little critter, hope I manage to get to the showers before Yang does." Blake was angry that the bug manage be stuck between her butt and causing some pain and itchiness that starts to come, but can do nothing but just go back to Beacon and get the little thing out in the showers, she is not going to pull down her pants in the forest, especially for Yang to see.

And so, she tries to walk by with Yang, the latter unaware of her companion's uncomfort.
