Waaaahhhhh!!! What an artist! Usually, the artists draw girls in very girly clothes and then either "add erection" or "subtitle" the images with something like "Larry becomes Laura" (think of Peach of Andy). But here you can clearly see that they are boys, yet with a slight girly appearance (actually, at young age boys and girls can be easily confused).
Just noticed another thing. Usually, I get attracted by "girls with dicks". The reason is simple - I like girls, and I like cocks. But here, since these boys have a distinct male appearance (despite the female clothes, female postures, female behaviour), I do not get attracted by them. Yet I fantasize about being one of them (this is usually my ultimate fetish quality control 😁 )
