She laid back on the bed hands in her pussy awaiting him to return. She could feel the metal speculum open her wide. Her clit hard. As she laid there her wetness grew in anticipation she had not followed directions and squirmed too
much. He had reached in to the bag of tricks grabbing a blindfold. He laid it over her eyes reminding her to keep the speculum in and her hands on her clit. He walked out to grab the machine that he enjoyed watching fuck her on his way back he grabbed some rope to keep her legs open and her pussy available.
He decided on a frog tie where she would really be left in a open position for him. He knew the submissive in her would allow him the ability to tie her in any position he saw fit. He bent her legs fully at the knees and bound the separately ankle-to-thigh, and also just behind the knee. He then tied her wrist in each side to the ankle thigh combination.
He slid between her legs knowing that she could not squirm. He was thrilled and excited to be able to taste it and watch her not be able to squirm out of his grasp. Grabbing her hips he bit down on her clit. Her hips flexing with no place to go. Her mouth open trying to be quiet with no idea who was in the other room. He could feel her legs shaking. Her wetness growing he wanted her wet enough that when he slipped the machine into her he would need no extra lubricants. He continued to enjoy the warmth of her lips. The moisture growing her moans slowly getting louder. The control of her body was all his. He slide out from between her legs slapping her pussy. Her mouth still wide open just on the verge of her orgasm that she wasn't yet permit to have yet.
He had to do a quick set of headshots but he planned to leave just the way she was With Her legs were open wide. He lined the machine up with her pussy moist enough to slide it in. He turned the speed up just to a medium speed reminding her to stay quiet. He slid the blindfold back over her eyes distracting her with nipples clamps on her nipples. Watching the get hard as he reached down putting the 3rd one on her clit. Her mouth moaning as he reminded her not to cum while he was gone fully knowing the predicament she was in would not allow that to happen. He knew he had planned to come back in and speed it up and enjoy what her pussy looked like. He walked out closing the door.
Her mind focused on the thrust of the machine counting the thrust. Trying to not focus on the fact her body ached to scream. The clamps feeling tighter as her nipples and clit became engorged. What felt like hours she heard the door quietly open and closed quickly. He turned off the machine but didn't remove it. He could feel the wetness dripping out of her as he whispered in her ear you didn't last not cumming I will have to figure out how to punish you for not listening. My client is switching outfits then I'll be back as he reached down and turn the machine up to full speed. Reminder don't make to much noise as he grabbed the chain connecting the clamps giving them a tug. I can make sure you stay quiet if need be as she felt the ball gag lay between her tits.
