Michael looked through the camera lens, watching the expressions on Violets face as she continued to tighten her sphincter on the hard rubber plug. Powerone would love these pictures, watching as Violet attempted to please him.

“NNNO, now what, it burns, is it broken?” she screamed as she felt a burning sensation in her asshole, spreading from the butt plug and slowly sliding deeper into her anal tract. Her hands went to her ass, attempting to pull the plug from her ass.

Michael was quicker, slapping her hands out of the way. “Don’t you dare, or we start all over again. It is just the other test of your abilities. If you don’t grip the butt plug tight enough, it will release a liquid. This liquid is like Ben-Gay, it burns and gets worse the longer it is on the skin.” Michael smiled as he said it. The liquid came out each time she squeezed the plug. There was a reservoir of it inside the plug and the harder she squeezed, the more that came out. Violet would never realize that no matter how hard she tried to squeeze tighter to prevent the discharge of the fluid, she was really causing more to come out. It was only drops at a time but the anal tract is a very delicate lining and the liquid was very caustic. 

It felt like gasoline was being poured in her asshole, the burning pain getting worse. She gripped the butt plug tight, her face contoured in pain as she tried to stop the burning. It kept getting worse, Violet not sure if she stopped the flow and the burning was from before or she still was not gripping it tight enough and it was still leaking into her rectum. “OOOOOWWW,” she screamed again, the shock returning again. She had been so tense and concentrating on squeezing tighter that she forgot to count the thirty seconds in between and was rewarded by a sharp stinging shock in her rectum. 

“You must pay attention Violet, you have to do both, grip it tight and also at the right interval.” Michael sat down on the bed beside her, making sure the camera could still see the pained expression on her face as she endured. “There, there, you can do it Violet,” his hand stroking her ass cheeks, feeling her muscles tighten, knowing that she was gripping the butt plug.

“Please, please, it’s still burning, please make it stop.” She begged him, her anal tract now on fire from the fluid leaked in it. She felt his fingers running up and down her ass slit, felt them bump up against the butt plug buried deep inside her rectum. 

Michael traced his fingers around her swollen and enlarged anal opening, stretched wide to accommodate the massive butt plug trapped inside her. “Tighter, Violet, grip it tighter,” feeling her ass muscles clenching and unclenching. “Yes, that’s a good girl, I know the fluid must be stopping by now. It just takes a while for the burning to stop. It gets worse before it gets better, but I know you can do it. I know you want to please Powerone.”

Michael sat down near her head, making sure that the camera recorded every groan and moan, every facial expression as the fluid continued to burn her anal tract, as the butt plug continued to shock her rectum. “You’re doing good Violet, I can see you are doing well.”

“AAAAH,” another violet shock running up her rectum, her sphincter clenching uncontrollably from the pain. Michael had lulled her with his words and she lost count. Pay attention, Violet, don’t be distracted, she thought.

Michael’s hands ran up and down her flanks, feeling a sheen of sweat beginning to form from the exertion. It had only been ten minutes, she had so much more time to go. Michael pulled his hands back, feeling the movements of her hips. He watched her ass, a slight pulling up, almost like she was fucking the butt plug inside her. 

Violet felt him get up and move back behind her. She knew how exposed she must look, her legs spread wide, her pussy open. She could feel the wetness between her legs. She began to pump her hips up and down, it seemed to relieve some of the cramping of the large butt plug inside her and the burning was not as bad. She knew how it must look, but she had to stop some of the pain. She imagined that it was Powerone inside her, making her fuck onto his big cock, forcing her to masturbate his powerful tool with her sphincter.

She jumped when she heard a knock on the door, knowing that anyone at the front door could see her naked body. “Don’t answer the door, please. OWWWW,” forgetting to tighten on the butt plug, her rectum shocked again. It was getting very painful now, her sphincter clenching tightly whenever her rectum was shocked.

Michael was already at the door, opening it, the outside light shining brightly into the room, Violets naked body in the direct view of the door. A delivery boy holding a bag was surprised at the scene before him. He was about the same age as Violet, a university student earning money delivering food. 

Violet began to get up, her hands trying to cover her naked ass, sitting up on the low bed. “AAAAAHHH,” the shocking butt plug shooting off in her rectum, Violet too upset about her nudity to worry about the pain shooting in her asshole. She could feel the butt plug twisting painfully inside her asshole as she tried to cover her nakedness.

“What do you think you are doing,” slapping her hard on the ass, pushing her back down on the bed. “You’re not finished yet. It’s only my dinner, nothing to worry about, I’m sure the young man has seen naked young ladies before.”

“You don’t mind, do you,” he asked the shocked delivery body.

“AAAh, duh, nnnno, I guess not,” stammered at the unexpected scene before him. He had seen many strange things while making deliveries, but this was the most erotic. He guessed her to be about his age, maybe even a student at the same university. Not real cute, but naked, she looked good. Hell, you put a bag over their head and they all look alike! He wasn’t sure what she was doing, but he didn’t care, his eyes feasting on her naked body, his cock bulging out the front of his pants.

“Now Violet, calm down, you’re going to scare the poor boy,” stroking her face after pushing her back down on her stomach. He could hear her groans, knowing that she was not gripping the butt plug and the electrical charges were almost continuous and increasing in current. “Now pay attention,” whispering into her ear, “get back to squeezing the butt plug with your sphincter before the electricity fries your rectum.” He saw the muscles in her ass contracting, knowing that she had begun to grip the plug again. “Good girl, now look back at the camera again.”

Violet turned her head back to the camera but was met by the stare of the delivery boy. She started to turn her head away.

“No, keep staring at the camera,” pushing her back over again, making her face the delivery boy.

He smiled at her, as he saw the older man rubbing his hands sensuously over her young body. What the fuck has this guy got that she allows him to do that? He followed his hands and saw the butt plug sticking out of her asshole, her asscheeks unable to hide the large instrument. What did he have stuck up her ass?

“I’ll be with you in a moment, you don’t mind waiting for a second, do you?” Michael smiled, seeing the bulge in the boy’s pants. No he would wait all day as long as he could ogle Violets naked body. He saw him nod yes.

“Now Violet, pay attention to your training. Squeeze, hold, squeeze and release. Wait 30 seconds and begin again. I know the electricity is painful now, but it is your fault. You disobeyed too many times. Are you all right? Are you going to obey?”

“Yes,” she said quietly, paying attention to her sphincter training, not wanting any more of the shocks in her rectum. “The burning, it’s getting worse, please make it stop,” she begged, her anal tract now burning from the caustic fluid dripping down inside her. 

“Squeeze tighter, you know the rules. Now I want you to spread your legs open again. Powerone wants to be able to see your pussy and asshole in the video. Can you do that for me, Violet, show the camera your sex?”

“Make him go first, please, not in front of him,” she begged. She was rewarded with a sharp slap on her ass, the cheek turning red instantly.
