In the bedroom.

It took Michael a few minutes to stow the dishes and clean up the kitchen. We he was done, he walked to the bedroom, but before he opened the door, he got down on his knees and gingerly opened it. The room was dimly lit, and the blinds and curtains were pulled, leaving the room in near-total darkness. At first, he didn't see Mistress Alex until his eyes were somewhat adjusted, and a dark figure rose from the comfy chair in the corner of the room. Her body was silhouetted in the dim light. He saw and felt the rough material touch him when she got closer. Mistress Alex had changed outfit from strict headmistress to sultry witch. She wore a black coat with a hood, and underneath she wore a leather corset, leather gloves, stockings and knee-high leather boots. And with those boots, she gently stepped on his exposed penis.

"You've been such a horny dog since I walked into this filthy apartment today that I don't think you deserve to be a **** but a dog." She grabs hold of Michael's hair and guides him to the bed where a couple of items are lying.

"I'm going to transform your sorry excuse of a human into the dog you are." Grabbing the first object tells him to make a fist, and then she wraps his hand in electrical tape. She makes a couple of passes until it is firmly wrapped, then she takes the other hand and repeats the procedure. She inspects his hands which are now mitts.

"Aw, look at these cute paws!" she then makes him get on the bed, where she tapes his legs together, making him walk on his knees. She picked up the next item and held it in her hand. She brushes his hair from his face and meats his eyes.

"You ready to finish the transformation?" Michael nods his head resigned, and Mistress Alex fidgets with the made of neoprene and shaped like a dog's head. She holds it in front of him so he gets a good look at the mask before she puts it on.

"Cute, isn't it? She opens the hood and slips it onto his head. Adjusting it, so everything aligns and picks up the last article. A collar, she fastened it around his neck.

"There all done. Don't you look cute and now to finish the transformation." Mistress Alex spoke a short incantation before she pushed him over so he lay on his back. She grabbed his cock.

"Is puppy horny?" Michael was on his back with all appendages in the air. He barked an affirmative sound, and Mistress Alex started jerking the cock hard.

"Good puppies know that they only cum when their owners let, don't they." Michael barked again. Mistress Alex jerked him hard, and Michael was whimpering. And she continued to jerk him until the whimpering had reached a fever pitch, then she stopped. The whimpering became whining and half-barking as she once again denied him. She did so a couple more times, and for each time, Michael whining became more animalistic. After what must have been the tenth or eleventh time, she brought him to the edge. There were no more whimpering, only animalistic grunts, Michael eyes were that of some other being.

Sarah was shocked. Part three of this evening was complete. What had started with putting Michael into subspace, making him suggestible and empty. The tearing down of his persona at dinner and now replacing that with another was complete. She hadn't believed the posts online that said it was possible. The being in her hands was a being that had given up total control to her. Her own **** puppet. He would do whatever she wanted. She got up to the headboard of the bed. She lay back and opened her legs.

"Come here, boy, fuck me until I let you come." Michael got on all fours and bounded up to her. She had to help him insert his dick into her because he couldn't do anything delicate with his curled-up and bound hands. But when it was in her, he started to work her like a bitch in heat. Michael fucked her for minutes, and for each minute that passed, his moaning became more and more guttural and animalistic. She wondered what his expression was like under that mask but imagined that it was a grim expression with gritted teeth, nose flaring and burned eyes. Sarah had cum three times before she felt overstimulation set in. She wanted to stop and take a break, but Michael didn't or most likely couldn't stop. She had to slap him before he heeded her, and now Mistress Alex was pissed. She towered over him, looking most displeased and Michael cowered and pathetically whimpered.

"Bad doggy!" she roared and continued.

"I thought I could trust you, but you're just another bitch!" Michael cowered even more, knowing he screwed up.

"I had planned such a nice finally for tonight, but then you horny fucking bitch ruined everything." She got up and exited the bedroom. Michael sat there on his hand and knees. He heard her walking down the hall and opened the suitcase. Michael sat there waiting, scared shitless for Mistress Alex to return. It took a minute for her to return, and her expression had not changed when she did.
