My body ached from its use yesterday. I moved to Master and knelt by his bed. He was beginning to wake and reached over and grabbed a handful of my hair and pulled my head to his cock. It was semi-erect. My lips immediately sucked him in. I swirled my tongue around the head and licked feeling it grow inside my mouth.
It quickly began to become too much for my mouth but Master kept my nose to his pubic hair until I began to gag. He released my hair and allowed me to work his cock with my hands and mouth. I tried to take more of him down my throat but gagged each time.
Master pressed a button above his bed and the girl from yesterday entered the room. She moved beside me and rooted me out of the way and immediately buried Master's cock down her throat. She bobbed her head slightly, keeping the enormous cock all the way down her throat.
Master's hips were bucking and he began to grunt as his orgasm came and his cum pumped into the girl. I was ashamed and could not look as she had pleasured Master, where I could not.
Master gave some instructions to the girl and she led me to the far wall of Master's suite. She clipped the cuffs on my wrists to a hook on the wall. She placed a gag in the shape of a small penis to my mouth. It pressed into the back of my throat and gagged me. She cupped my breast and whispered into my ear to "relax and slow your breathing". I did as she instructed and my anxiety subsided. The girl then attached a very large spreader bar to my ankles and went back to Master.
Master told me that my inability to take his cock into my throat had displeased him. He instructed me that I would be wearing this penis gag so that my throat would become accustomed to having a cock in my throat. Now I was strapped to his wall in order to watch my slave sister Jennie be rewarded for her skills.
Master arose and moved toward me. Jennie followed and lay across a leather pad. Master came behind her and nudged her pussy with his still erect cock. Master's thick cock sliced the wet folds of Jennie's cunt. His movements were slow and steady, each gyration made her shudder. Her more than ample breasts swayed as she was fucked by our Master.
She whimpered with each stroke but met each one with equal force back into him. Master leaned forward and cupped her dangling breasts and pulled her back into him. She instantly became more vocal and threw her head from side to side. Master quickened his pace as Jennie became more out of control.
