"Can..." Jen hesitated, "Can I join Betty's new program?"
All three women turned to look at Jen. Tracy looked at her and smiled. She was proud of her daughter's growth, even if she was more like a dog than a person most days. Alice looked to be in mild shock. She had been helping Betty feed and walk Mina for the past week and what she had seen of her training left her feeling awkward. Amelia just looked thoughtful.
"That might not be a bad idea." Amelia said, "Betty did say that Mina seemed to behave when you were around. Maybe with your help Betty can knock her into shape again. Are you sure you're up for it though? I understand that the training is somewhat intense."
"I can handle it." Jen said with more confidence than she actually felt. The remnant of the curse helping to spur her on.
"Is it alright with you?" Amelia turned to Tracy. "It would mean that Jen would probably have to stay here at least another month, if not longer."
"I don't mind." Tracy said. "My other daughter will be here too. It will be nice to have the house to myself for a while."
"Then it's settled." Amelia said. "Jen will be staying with us again to help Betty train Mina. Alice, why don't you take Jen to Betty's office and have her checked in. When you're done there I'm assigning you to be Emily's trainer. I know you prefer caretaking over training, but I need the best and right now you are it."
"Fine." Alice sighed. "But this means I get that raise you were promising. And if I'm going to be in charge of Emily then I want to have control of the program as well. I don't want to have to rely on you or Betty to relay orders to the other trainers and caretakers. If I'm going to do this then I'm going to do this right."
"Agreed. Stop by my office before you leave today and I'll have the paperwork ready for you to sign."
Satisfied, Alice stood and beckoned Jen to follow her as she left the room. Jen trotted after her, obeying the hand signal without thinking. They walked down a few hallways until they reached a familiar door. Alice opened it and Jen entered Betty's office. She was expecting to find Emily here being examined and fitted for her pads, but only Betty was present. She was meticulously picking apart the stitching on Jen's old pads under a large magnifying glass. She looked up at the intrusion.
"Jen wants to join your special class with Mina." Alice said. "Amelia approved it."
"Wonderful!" Betty's face lit up. "I had a feeling you would be interested! Come climb onto the exam table and I'll get you set up!"
Jen crawled to the large steel table in the middle of the room and stood to climb onto it. As she turned to sit she caught sight of Alice's face as she shut the door behind her. Her face was a bright pink with a band of red across her nose and cheeks. Jen wondered why.
"Up on all fours Jen," Betty commanded, "There's a bit of new kit I need to put on you for the training and I'll need to examine you for intake as well."
Jen got on her hands and knees. Betty grabbed a bunch of leather straps from her desk and threw them over Jen's back. The straps wrapped around her chest and shoulders like a harness. She looked down and saw that they seemed to frame her breasts, curving around the outside and passing down her sternum. Betty tightened the straps until they fitted snugly.
"Can you breathe alright?" she asked. "Not too tight around the ribs?"
"It's fine." Jen said. "What's it for?"
"So I can tie you down more easily. This special training of mine is like nothing you've ever experienced before. Ass up, please."
Jen arched her back so her ass was a little higher in the air. She gasped when she felt something wet and cold dribble onto her asshole. She was about to ask what it was when she felt something cold and hard press against her pucker.
"Just relax." Betty said calmly.
Jen found that difficult. Whatever Betty was putting into her was uncomfortably large. She whimpered as she felt her sphincter stretch to accept the object. Whatever it was, it was definitely too thick to be a thermometer and much too long for some kind of suppository. It seemed to get wider as it went. Jen's whimper turned into a pained whine.
"Almost... Got it!" Betty said triumphantly.
Jen felt her asshole close around the far end of the object. Wincing, she turned to see what Betty had done to her. She was surprised to see a fluffy brown dog's tail sprouting from between her ass cheeks. Betty held up a mirror.
"You like it?" she asked, "I had it custom made to match your hair. It will have to be taken out when you need to go number two, but otherwise it's designed for long-term wear. Give it a wag!"
Jen tentatively shook her hips. The tail swung back and forth and Jen felt something shift deep in her ass. She gasped at the mild pleasure it caused.
"It's weighted so every move it makes wiggles the plug. The happier you are, the happier you'll feel!"
Jen was barely paying attention. She had never realized that having something in your ass could feel so good. She shook her hips again, a bit harder this time, and was rewarded with waves of more pleasure. She felt something moving down her inner thigh and looked down to see what it was. A small trickle of fluid had dripped from her pussy and was running down her bare skin. Betty noticed it as well.
"I'm glad to see you're enjoying it." Betty said with a grin. "I've got a lot more for you to experience. Let's go see Mina and get you set up for morning activities."
Betty helped Jen down off the table and attached a leash to her collar. She lead the teen out of her office and back up the corridor towards the lobby. About halfway there she turned down a smaller hallway lit by much dimmer lights. At the end of this hall was a heavy door that Betty unlocked with a key. On the other side was a small empty room with an identical door on the other side. Betty made sure the first door was shut securely before she unlocked the second one.
When the second door opened Jen was met with the strong odor of sex. It was unmistakable. She wrinkled her nose and followed Betty into the larger room beyond. The lights were even dimmer in here and Jen could see almost nothing. She could hear something though. A sort of rhythmic whirring and clicking sound. Betty fumbled along the wall for a moment until she found the light switch and flipped it on. Jen gasped loudly at the sight that greeted her.
Mina was up on a padded bench. She was on all fours had been strapped down tightly. She was wearing the training pads she'd had when Jen last saw her but was also now sporting a leather harness like the one Jen wore. Her eyes had been covered with a thick black blindfold, her ears had a set of headphones over them (with floppy dog ears on top), and a large ball gag kept her drooling mouth wide open. The real shock was the machine mounted behind her. Betty lead Jen around so she could get a better look.
It was unmistakably a sex machine. A piston on the front kept pumping a massive red dildo in and out of Mina's stretched cunt at an impressive pace. The bench beneath her was covered in a thick layer of fluid. Jen was wondering how so much could have come out of such a small body when she heard a click from the machine and the piston extended to its full length. With a squelching noise more thick white goop began pushing out of Mina past the giant invader as her stomach bulged slightly.
"Ok Jen, hop up here and we'll get you started as well."
Jen turned to find Betty patting the cushioned top of another identical bench. The machine on this one didn't have a dildo mounted yet, but Jen could see them on a rack behind it. The largest one was a true monster, almost three inches thick and a foot long. All of them were red and shaped like a dog's cock. Jen looked hopefully at the smallest, a tiny little stub compared to the others. With trepidation Jen clambered up onto the bench and placed her hands and knees in the spots Betty indicated. Several straps were brought up and attached to her new harness and then tightened so that her shoulders were pulled down against the backs of her hands. Two more straps were wrapped around each leg, completely immobilizing her.
"Comfortable?" Betty asked, stepping back into view. "I won't blindfold or gag you like I did with Mina, those are punishments, but you do need to wear a headset for your conditioning."
Betty held up a pair of headphones with furry ears on them.
"I'm going to give you a different program from Mina's, since you are actually well behaved."
She placed the headphones over Jen's ears and all the sounds of the room disappeared. She watched Betty's lips move, but not a single sound got through. Betty turned and pulled a wheeled cart over in front of Jen's face. On top of it was a small monitor. Betty turned it on and a cartoon started playing. It featured young women frolicking like puppies in a field, naked and free. A soothing voice started speaking through the headset, telling Jen to relax and watch the girls play.
Jen was just beginning to lose herself in the voice when she felt something bump against her pussy. She gasped as the pointed tip slid inside of her. She could tell it wasn't the small one she was hoping for, but it also wasn't the massive one she had been dreading. It inched its way forwards, filling her up perfectly and completely as if it had been made just for her. When it was fully inserted it paused for a brief moment then slid back out before reversing and plunging back in again. It started out slow, but quickly increased in pace until Jen felt like she was being thoroughly and properly fucked. She moaned loudly but could barely hear it through the headphones.
The voice in the headset drew her attention back to the screen. She tried hard to focus on it and saw that the scene had changed. It was still naked girls playing like dogs, but Jen could see that some of them had dog cocks where their clits should be. As she watched, the girls with cocks began mounting the other girls and fucking them with wild abandon. The dildo in her pussy seemed more real now. She swore she could feel the weight of one of these dog-dicked women pressing her down instead of the straps. The camera zoomed in on one pair and Jen watched as the girl on top drove her dick all the way to the hilt and held it there. As it did the machine mimicked the action on the screen and pushed the dildo as deep as it would go. Jen knew what was coming but was unable to prepare for the jet of hot liquid that shot deep inside of her as her pussy spasmed around the fake dick.
Her orgasm hadn't even finished when she felt the machine begin to move again.
"No!" she shouted. "No more!"
But the machine kept going.
She looked around frantically, but with her body tied down and the screen in her face she couldn't see much. She didn't know if Betty was still there or if she had been left here alone with Mina. The cartoon had now become an orgy of dog girls being fucked by other dog girls. Every once in a while it would focus on one pair and Jen would be treated to another blast of hot spunk. In between orgasms she would plead with Betty to release her, but no relief came. Eventually she lapsed into moaning punctuated by the occasional exhausted whine as she came again and again.
