>>280499862Such a good idea for a manga but
1. It's not ecchi so it's wasted
2. It doesn't even try to make the genderbending incest relationship work (it flat out goes 'oh yeah she loved her brother sexually before and now he's a girl she still wants to fuck him but can't hide it because she has a cock now')
It would have been much better if it had been a regular romance manga with his(her) sister trying to get over her incestuous thoughts by fucking other girls with her cock. Also I dislike genderbending.
Give me a yuri manga but one of the characters is a futanari WITHOUT genderbending. Also if you're doing that gimmick go a bit harder on ecchi.
