I actually like this one. If it wasn't for the artist's horrible translations, having a guy in a "futanari high demand" type of job is an accomplishment all on its own. There could've been any other futa in his position. Nia also has a habit of making futanari having sex just seem so... boring. Makes it seem like being a futa in their world is terrible going by the expressions this futa has fucking her clients. Props to the dude fucking women in this world where futanaris are superior, regardless if it's an act of pity or not.
I think it's because sex scenes are what he draws the least, even if i think he's improved a lot since his early days, the scenes he draws are not very complex most of the time.
On the other topic, i kind of like that some futas just treat it as a job, of course they enjoy it but at some point you can't just focus on feeling if you have a line of women waiting every day to get pregnant and futas are in high demand because there's that many of them, then i get why some seem so bored, like the futanari doctor in the second chapter, out of all the futas in this series she seemed like she most "profesional", like it was just another procedure. The third one did seemed like ntr, thought
