Out of Our Element

Yujin picks up a quick, three-day studio job to make a little cash, and it doesn't seem like much on the surface until she actually gets there. It's not a regular film, but an adult film, and even then she isn't too phased by it because she's mature enough to handle it. Or so she thinks. Because the real issue arises when one beautiful girl can't seem to stop blatantly locking eyes with her while doing the most erotic things Yujin has ever witnessed.

And when this girl takes very overt interest in her? Going as far to corner her? Yujin finds herself more tempted than she can bear.

Or

Yujin is a coffee-runner on a lesbian porno set and Wonyoung is one of the actresses.
