The art above is the first sketch of a hucow player being bound and milked in the dairy. This image when complete will be used in multiple places where the player is milked in this way (standard milking, and the dairy job). The artist Silverjile has once againgraciously cleared me posting the early versions here.
If you want to see more of their work, you can find it through the following NSFW link here.
P.S. Sorry for the delay regarding this, I had a hard time explaining exactly what I wanted (strangely it was very hard to find hucow bondage references similar to what I was looking for, as hucow's are normally bound standing with their arms bound upwards). Hopefully the artwork should pick back up a little quicker now :)
