Sketch Commission for http://www.furaffinity.net/user/alonelywolf. He wanted a followup to his last commission (https://www.weasyl.com/submission/1069833/commission-cale-and-colin) with Cale free, having tied up Colin to worship his feet, while shoving his own back in his brother's face. Hope you like this, alonelywolf.
