Emily practically bounced into therapy. She had a smile on her face and a pep in her step, she hadn’t felt this happy since she had first started having bladder problems. She actually couldn’t wait to get into Catherine’s office for once.
When the door to Catherine’s office opened Emily stood straight up. It looked like she caught her therapist by surprise with the eagerness with which she walked into the room. She strode in and then turned to watch Catherine close the door behind her.
“Hello, Emily, you se-… Oh!” Catherine was suddenly stopped as Emily wrapped her in a tight hug.
Emily didn’t care that the thick diaper she was wearing was pressed against Catherine’s legs. She didn’t even care that in such close proximity there was no way the therapist could miss the crinkles coming from her waist. When Emily pulled away, she could see that Catherine was almost too shocked to respond.
“Thank you!” Emily said cheerfully.
“Huh?” Catherine mumbled.
Emily walked further into the room and saw the toys on the floor. Without hesitation she stripped off her skirt to reveal the bottom of the onesie she was wearing underneath. Her blouse followed until the onesie was the only thing covering her diaper. It was a lime green colour with white borders and on the front it read “Mummy’s Angel” in baby block style letters. It was the first time Emily had worn and “little” clothes to therapy.
Emily wasted no time opening up the colouring book and playing. She saw Catherine’s feet come round the couch. The therapist remained standing for a few seconds before sitting down in her usual seat. Emily looked up at her and smiled.
“You seem very chipper today.” Catherine said. Her voice was almost suspicious.
“Uh huh.” Emily replied.
“Why’s that?” Catherine, who was much more used to the dour and quiet Emily asked.
Why was Emily in such a good mood? Well, it felt like everything had changed for her and it was all because of Catherine. After their last session where Catherine suggested that Emily try to be “good” things had improved dramatically. Emily hadn’t been spanked or punished in a week, instead she was getting plenty of praise and rewards. The more Amelia called her a good girl the better she felt. Each time those magic words left Amelia’s lips Emily stirred within her cage. Whilst the orgasm on the changing table had been the first in a long time, it hadn’t been the last.
Emily relayed all this to Catherine, though she omitted the sexual elements, and remarked about how much it seemed to have improved things. Catherine seemed relieved and pleased that the situation had stabilised. However, Emily could see there was a part of Catherine that was a little concerned.
“What’s wrong?” Emily asked as she put down the crayon she was using to colour a picture of a mermaid.
“Nothing’s wrong.” Catherine said with a small smile, “That’s an interesting outfit you’re wearing.”
“Mommy chose it.” Emily replied quite happily.
Emily had quickly gone back to colouring so she missed Catherine’s eyes nearly bulging out of her head. It had indeed been a quick turnaround in her personality. It felt like she had a new lease on life despite all the limitations on it. There was a part of her that was worried about it as well. She wasn’t used to feeling so good about herself, she worried this was some sort of manic phase and that it could come crashing down at any moment. Emily assumed that was what Catherine was concerned about as well.
Emily was OK though. What she had proven in the last week was that she wasn’t a burden and Amelia had noticed it. After all, a burden wouldn’t be called a good girl as often as she had been. A burden wouldn’t have had all the nice rewards Emily had been given.
Catherine started asking more details and taking notes. Emily told her about how she was doing everything Amelia said without question and how her wife appreciated and rewarded that behaviour. She described how she felt like she had found her place in the world.
Emily could see that Catherine still didn’t fully understand. That was alright, she was aware that it was a strange situation, it just happened to be one that worked for her. As she talked, she played with a couple of small dolls, undressing and re-dressing in different outfits. She was aware she was being more open than usual. Maybe it was just because she was in a good mood, but she had been feeling that way for days now.
“And you’re happy with everything?” Catherine asked, “I have to say it seems you’ve had quite a turnaround in attitude. Was there anything in particular that caused that?”
Emily remained quiet. Whilst she was being very open and was aware of the sexual relationship between her therapist and her wife, she didn’t really want to say that what had really changed her attitude was Amelia fingering her ass until she exploded. She just shrugged her shoulders. Fortunately, Catherine didn’t ask more questions on that subject.
“Out of interest, what seems to get you praised as a “good girl” exactly?” Catherine asked.
“Using my diapers, playing quietly, following rules, doing what Amelia tells me…” Emily said and trailed off as she tried to think if there was anything else.
“So… acting like a baby?” Catherine pushed.
Emily opened her mouth to refute that claim but, after thinking about it for a second, she realised Catherine was right. She got praise for acting like a baby, she was punished when she didn’t. She had long felt like a baby with the diapers and everything else that Amelia had brought into their relationship but it wasn’t often she heard someone else say it. Suddenly she felt a little less happy that she had been good.
“It’s OK.” Catherine said when Emily hadn’t responded for a few seconds, “We’ll move on. How has your anxiety been?”
The session went back to normal after that. Emily was happy to get away from the “baby” topic and focus on her mental health which she thought had improved a lot recently. Indeed, Catherine seemed pleased by the progress she had made and the more she talked about it the more her look of concern was replaced by a smile.
“I’m afraid that’s all we have time for.” Catherine said after a little while, “but I’m pleased that you seem happier.”
“Me too.” Emily said with a little smile.
Standing up with a flurry of crinkles, Emily took one step towards her clothes and froze. Her tummy muscles were pushing down and she could feel a warm and sticky mass spreading over her rear end. She stared in ahead in shock. She hadn’t even realised she needed to poop. It had simply happened too rapidly to react to.
“Emily? Is everything OK?” Catherine asked.
Emily was still staring off into the middle distance. She held her breath and bent over slightly as she pushed down. The sticky patch grew. She could feel the back of the diaper bulging out under her onesie, the lump growing bigger until she finally felt empty. Almost immediately upon finishing she started wetting herself as well.
This was far from the first time she had messed herself, of course, but it was the first time it had happened without her having any warning. As she slowly straightened up again, she remembered where she was. She was about to continue leaving when she felt a hand on her backside. Emily let out a little gasp as the stinky waste pressing against her backside was pressed a little closer to her skin.
“Did you know you needed to go?” Catherine asked quietly.
Emily shook her head. It didn’t seem like a therapeutic question; she wondered if it was borne entirely from morbid curiosity. She stepped away from Catherine and started picking up her clothes. She suddenly wanted to get out of the office as soon as possible. She felt ashamed.
“Emily.” Catherine said with a little more authority than the messy woman was used to, “Get dressed before leaving.”
Emily looked around. In her haste to get out of Catherine’s office, where all she could think about was running back to her Mommy and the car, she had nearly walked out of the private room in nothing but her onesie and soiled diaper. She stopped and started to pull her skirt on. However, once it was halfway up her legs she stopped. A strange calmness entered her and she turned back to Catherine. Red in the face and feeling embarrassed, Emily wasn’t sure what had come over her.
“Do… Do you want to change me?” Emily asked her therapist.
Emily could immediately see that Catherine was shocked. The therapist had seen Emily being changed, in fact she’d seen plenty of embarrassing moments for Emily, but she’d never been directly involved. But if Catherine was sleeping with Amelia, and Amelia was Emily’s Mommy… Didn’t it stand to reason that Catherine should be looking after her as well? She was only a baby after all. Catherine had said as much herself.
“I, erm… Well, I…” Catherine stuttered. Emily didn’t remember ever seeing her so nervous before. Certainly not in a professional setting.
“It’s OK.” Emily said as she pulled her skirt up, “Mommy can do it in the car, it’s just a bit more awkward.”
Emily’s words seemed to strike a chord with Catherine. The diapered woman was just picking up her bag and reaching out for the door when she was stopped.
“Wait.” Catherine said. Emily turned and looked at her wife’s lover. She seemed to be about to say something that was clearly against her better judgment, “Come here.”
Emily was now growing used to doing as she was told without questioning. She walked across the room back to the area where she had sat on the floor playing. Catherine seemed to still be having second thoughts. Emily was sure that there was nothing in the therapist’s handbook that mentioned changing your client’s diapers.
“Do you… have everything you need?” Catherine asked as she gestured to the bag in Emily’s hands.
“Yes.” Emily replied. She knew the therapist meant everything needed for a diaper change.
Catherine looked around and took a deep slow breath. Using her feet she nudged some of the toys to the side to create a space on the floor. Emily found Catherine’s obvious nervousness kind of cute, it felt like a strange reversal of roles, in that room it was almost always Emily feeling anxious and pushing her boundaries of comfort.
Emily opened her bag and handed it to Catherine. As she looked through the changing supplies, Emily wondered if Catherine had ever changed a diaper before, even one on a baby. As Catherine pulled out the changing mat, now slightly stained after continuous use, and laid it on the floor Emily started taking her skirt off again.
“Have you changed a diaper before?” Emily asked.
Catherine dropped the bag and seemed to go quite red in the face. It was not the reaction Emily had been expecting to such an innocent question. If Catherine had such a problem with doing this, she shouldn’t have stopped her from leaving the room just previously.
“A…A couple of times…” Catherine stuttered, “Why? What have you heard?”
“Nothing.” Emily frowned with confusion, “I was just curious.”
Catherine gave Emily a long searching look before continuing to get things ready. With the mat on the floor out came the diaper, wipes, and powder which Catherine placed to the side. Emily could now tell that her therapist was experienced, she knew just what she was doing and had a very similar technique to Amelia in the order she was doing everything. Emily unsnapped her onesie and lifted it over her head revealing that she hadn’t been wearing a bra and leaving her naked except for the bulging disposable.
“OK, if you want to lay down.” Catherine said, “I really shouldn’t be doing this. If it was anyone else…”
“But it’s me.” Emily gave Catherine a little smile as she laid down. She did her best to avoid sitting on the heavy weight in the back of her diaper though it was impossible to entirely avoid making a mess.
Emily laid back with her feet on the floor and her knees spread. The tapes on her diaper were torn off and the front was lowered. The stink got worse but Emily barely noticed it these days. Catherine certainly did though as she turned her face away. She soon regained her composure and got to the slow and laborious work.
Emily waited and enjoyed the cool wipes that were rubbed against her skin. The poop hadn’t been left long enough to get uncomfortable but it still felt wonderful to feel it get removed. She wondered what Catherine must’ve been thinking, she surely had never had a patient on the floor of her office like this. Despite that, she was doing a great job and Emily wondered idly how much practice she’d had.
After a couple of minutes, the messy diaper was balled up and pushed to the side. Emily sighed as she felt the fresh diaper get slipped underneath her. Few things felt as nice as a new disposable after spending time in wet or messy ones. A sprinkling of powder had Sam smelling like a baby before the front was pulled up between her legs and taped closed. Considering Catherine’s professed lack of experience, she had done a very good and efficient job.
“Is that alright?” Catherine asked nervously.
“Yeah, seems perfect.” Emily replied as she sat up.
Emily stood and before she could start getting herself dressed Catherine was snapping the onesie back together. She finished pulling on her clothes to find Catherine handing her the used diaper like a particularly stinky parcel delivery.
“You’ll need to take this with you.” Catherine said before retreating to the windows, “And I’ll need to air the room out a bit.”
