I really wish the author continue his futanari story, page 13. Its such a waste to just end it there. Still trying to tweet it to him about it but it seems like he is too preoccupied with his horny housewife and ntr troupe, his current WIP doujin. Also, please check out his twitter and support him. It seems like he's always in and out of depression state.
The artist has resumed activity on twitter (although it seems like they no longer go by their old circle name). Mostly just female stuff with occasional femboy content./yaoi content.
