I opened the door slowly, knowing the squeaking sound would add to her discomfort. She was blindfolded and collared, being led by a chain leash. We had driven to a secluded business park and it was close to midnight. "Take your clothes off", I simply said. She has no issues with compliance and a few moments later, she was sitting the passenger seat naked. I snatched my "special bag" from the back seat and pulled out a heavy blindfold. I grabbed her by the hair and forced the blindfold over her head, covering her eyes. Allowing her some comfort, I let her adjust it before getting her out of the car. Standing there naked except for a blindfold. The air was cool, but not cold. Clearly, she was excited and nervous. I could see goosebumps on her arms. I quickly bound her arms behind her and snapped on a heavy metal collar and chain. Not her favorite, I know, but it is mine! I snapped the small lock in place. “No escape for you tonight, slut!”. 

We entered the room and I could immediately smell the candles. I led her quickly to a second room. She stayed close to me so she could feel my presence next to her. She started to speak, but I was not interested in what my slut had to say right now, so I quickly put a leather gag in her mouth. The room was warm. In the center sat a single chair. Around the outside of the room were various appliances. “Appliances”, that’s as good a word as any. A few whips and floggers, as well as ropes of various lengths hung on the wall to set the mood. I sat her on the chair. Above the chair fastened to the ceiling were many hooks - also with rope hanging from them. I attached one of the ropes to her bindings, drawing her arms back and up slightly. She could no longer sit and she bent forward. I slipped ropes on her ankles and drew her feet apart. I could hear her breathing and I could smell her sex. I pulled a flogger from the wall and toyed with her, trailing the light leather straps across her back and ass - then snap. She stiffened and squirmed. I wanted to hear her pleas so I removed the gag. I rubbed the rising red marks on her ass before I again - snap. She winced and tried to get free. I raised her arms a little more so she could not move at all. Then back to gently rubbing the new welts on her ass. With each rub came a brush across her pussy, a finger slipping into her, lingering there before it is replaced with yet another snap. My own erection was being tamed by my heavy black jeans - and I wanted to have a little different kind of fun with my little slut! I removed my clothes and stood behind her - watching her breathing. From my "special bag" I pulled my favorite toy, plugged it in and turned it on. Again, I rubbed the swells on her ass, putting the vibrator on the back of my hand as I moved toward her pussy. "Do not cum" I said and I pressed against her swollen clit. "Oh please Master" she squealed. "NO". She came anyway - I knew she would. "Now you've done it", I said. 

What happens next?
