Hello all! Here's the sketch for next pic i just finished. Didn't draw a threesome for quite a while so i'm fixing it with this commission for @KDPKenn ,hope you'll like it. Should be done in next 5 days. Poll for next pic will be in a couple days so you can drop some options in comments and i'll see what i can add in it.
