Kotetsu's new undies (Patreon)

When do you think Barnaby is going to realize that using his powers in such state is only making Kotetsu's ass grow bigger and bigger? 

Here is the drawing for Kotetsu and Barnaby, who got third place in the last poll. The patron who submited their entry got to choose the kink they wanted to see them featuring (in this case, Underwear transformation) I felt like making a fart version too so I asked for their permission (which will be exclusive to patreon)

I hope you all like it!
