There is a series of several episodes (and counting) dedicated to these 'translated' videos of female idols. I thought the Yura one was the best example, hence my embedding it. Unfortunately for Nana fans, her video was removed due to copyright, but hopefully there's at least one girl that you like here.
These are arguably meant to make you laugh rather than turn you on, but the subbed parts are nicely punctuated with sexy dancey content, making these videos a solid choice for your "Fap Later" playlist. Admittedly, it is a slightly simple and repetitive kind of comedy, but even if you don't appreciate this style of humour you've got to give props to the creator for writing subs that fit beautifully with the facial expressions and body language of the girls.
The predictable whining in the comments is pretty funny too. We wouldn't be Anti Kpop-Fangirl without taking the odd jab at overly sensitive people getting wound up over trivial things, so here is the good stuff hand-picked from the plant of butthurt.
you dare compliment oppar? Not if you value your life.
Really? Someone's just having a bit of fun and making a joke that no one will take seriously (except fangirls, apparently), and they deserve eternal torture for that? Is it really a sin on par with rape and murder? On the contrary, the fap-gods will reward this person, in death, with exclusive fap material that would be unimaginable, here, on Earth.
This concludes the first IDGAF. From now on, I shall be accepting submissions for this series. I will publish any kpop fap material which is both good quality and from somewhere that isn't too obvious. Funny and creative stuff like in this article is a bonus too. Note that male fap material is ok, but the main focus will be females because of our audience. Please send submissions via ask.fm, twitter or email firstname.lastname@example.org. I promise not to hog it all to myself. May the fapgods bless your lustful souls!
P.S. Happy Cock (the uploader of the fine gifts above) is the first person I've seen to explicitly put the word 'fapcam' in a YouTube video title. I think it's great.
