Hard yaoi is always nice, but the plot of this story was a bit underdeveloped for my tastes. More than half of each chapter was composed of steamy sex scenes, which is hot on its own but unfortunately affected the character development of the seme and uke. Also, the characters' morals are low and they're very hedonistic (haha!) so I couldn't relate to the manga and it failed to engross me while I read it.
Pros: no girly uke, cool and semi-sadistic uke, hot sex scenes
Cons: poor character development, their love story felt rushed
I liked the extra best, it was funny and I hope it has
a sequel somewhere. :)
