It was finally playtime. I was always so sexually excited when these sessions started, never knowing what Master had planned for me. He always mixed it up to keep me guessing. My lack of foresight only added to my feeling of erotic helplessness, a form of mental foreplay.
Master commanded me to strip before kneeling next to his desk. An enticing pink satin box sat next to him. He had already selected the toys for today. He reached in and simply handed me my large butt plug and the tube of lube. I dutifully dribbled a generous strip of shiny transparent lube down the length of the rubber penis. I fingerpainted it to smear the lubricant around, lovingly coating every surface with its slippery goo. I then bent over and lined up the plug with my sphincter. I pushed out with my ass, and as I relaxed, it sucked a bit of the plug in. I pushed out again and again, and the rubber phallus entered me deeper with every pause. The plug always feels so much larger in my ass than it looks when sitting in my hand! I let out a grunt as my sphincter finally settled around the neck of the silicone dick.
Master smiled as he looked down at me. He clearly enjoyed the show I put on. The next toy was my remote-controlled bullet vibrator, already merrily buzzing away in a low-medium setting. I knew the delightful toy would get me excited, but these vibrations weren't strong enough to orgasm to. This setting induced a teasing foreplay. I smiled as I nestled it right on my clit. I loved where this was headed!
Master reached into the box again, and pulled out my gleaming stainless steel chastity belt. Pink rubber coated all the edges, giving it a feminine touch. I noticed the key wasn't in the lock. I wrapped the belt around my waist. I ran the rear cable over the plug, pulling it between my legs and sealed the vibrator beneath its metal front plate. As I yanked to snap the crotch strap shut, I grunted as the plug was forced a bit deeper in my ass. The ominous "click" let both of us know my fate was sealed. I ran my hands up and down the metal plate. I couldn't touch the vibrator buzzing away underneath, much as I wanted to.
