WIP. WaB. Carla's nipplefuck scene Sketch (Patreon)

A sketch for the upcoming nipplefuck scene with Carla, that won the poll. 

I think that at first variant Krowly will be just pocking her nipple, and Carla wont be so enthusiastic. But latter, when we will get nipplefuck potion in game Krowly will be able to go all the way inside and Carla will love it a lot more. So I want her to have neutral expression on this one to increase the contrast :)
