I have my slave tightly bound and helpless. I also have put a hood over his head and added the luxury of a tight gag over his mouth so he can't speak. This also restricts his breathing. He has been alone and in this position all morning. I arrive to hear his pathetic groans. I know he wants to be free, however I have other plans for him. Before that, I'm going to give him a little treat. His cock is hard, and I think I'll milk him like a cow. Would you like to cum slut? As I tell this to him and touch his cock, he squeals and moans like a little calf. I begin by sliding a bowl under his cock to catch his milk. As he struggles and squirms in his bondage. It's not long before he starts to quirt milk into his bowl. I decide not to allow him the luxury of a full orgasm and let go his cock go. He whines and groans, knowing he can't cum properly. His suffering is going to continue as I leave him gagging for more. Perhaps I will come back this afternoon to check on him...
