Lily Duolingo +18 by RougeFlair on Newgrounds
Duolinger is more than just a beneficial resource for those looking to learn a new language. It has also gained popularity among language aficionados. However, regrettably, it seems that even this popular platform is not exempt from the controversial Rule 34 principle.
Many have found that Duolingo ️ + Rule 34 fusion is out there. It could come as a surprise, but apparently, there are fan-made illustrations based on characters from Duolingo which adhere to the infamous rule that states "if it exists, there is porn of it."
