【tsuppan】Why pants even in the mountains?

CG 13 types 13 pictures.
All sizes are 2000*1500.

One sheet for each of the 13 unmarked Idol X stars.
I drew this to see what it would look like if nature and pants were combined.
I tried to keep the poses relatively natural without thinking too much about the details.
A little less erotic.
The atmosphere is a little different from usual, so please see the sample.
I drew this without thinking about the difference, but I made a bonus for those who can make a difference.
