I'm having a really hard time figuring out what the artist thought the point of this picture was supposed to be. Hazumi and Kurumi are the same VA, I guess that has something to do with it.

Wait... Where is the penis? The Last few times I saw this pic there was a huge dick hanging out of her panties.

This is one of several pictures, one version of the picture Hazumi has a penis, another one is pantsu-less and no penis

I think the idea behind this one is to show the difficulty Hazumu has with being a girl. For example not spreading your legs while wearing a mini-skirt

Basically she still is acting in guy mode. After being changed so abruptly by aliens I am sure Hazumu would've had this sort of problem at first. That is until it is corrected by Tomari who often lectured Hazumu on how to behave like a girl.
