HAHA, very suprisingly well done.
At first i was just seeing video and was thinking blam, but as soon as you could see the slash animated shit, you can tell it's very high quality. The sick part is this is probably going to turn on alot of 13 year olds, watching this twisted tentical sex. Well done though, hentai isn't my thing at all, but I hope this animation gets the respect it definatly deserves.
