This was really funny. I loved the choices the translator made, like "I will end you!" and all the "What the F*ck"s that kept popping in the latter part. Also, is this like a "Reverse Gay for Pay" situation, since the (formerly) straight girl pays her lesbian friend to have sex with her?
Plus, man, the dark-haired girl had some bad lovers. I mean, what kinda keep would just 'stick it it' without making sure their partner was ready? This reminds me of this web-coming I used to read where a lady says (something to effect of) "remember guys, there's more to it than just thrusting."
