Beth, after waking up, considered her options. A deal with Satrin seemed possible with her new-found pearl - they were really rare, a trade for her plug seemed like a good deal for both parties, and Satrin didn't seem that keen on keeping the toy anyway, with its enchantment wasted and all.
A slight rumbling reminded her of her other problem - Ryiah, the slimegirl, still occupied her bowels, and was probably unsatisfied with Beth's lack of plugging. Beth tried to force the invader out of herself, pushing her hands onto her slightly boated belly while staining her abdomen, but nothing seemed to move - her anal muscles were waaay to stretched to work at this point, and pushing with just her hands was way less than enough. Resigning to the fact that the slime will consider her as her home for now, she replugged herself, then went to sleep. She wanted to be fresh, to have a clean head for her upcoming meeting with Satrin tomorrow.
Her sleep did not come easily, however. The thought that a living, sentient being was inside her ass kept her mind occupied - it was similar to being... pregnant. It was obviously different in many ways, but in the end, she would have to... give birth to someone after a while. It just happened to be anal instead of vaginal.
Fortunately, Ryiah seemed content of just being inside her for the moment, not really bothering her in any way aside from the fact that she overfilled Beth's insides. It dawned on Beth that her best bargaining chip against the slimegirl would be to imprison Ryiah inside herself. She didn't have the option to force the slime out on demand, but she could prevent her... passenger from leaving via her plug.
Still, she couldn't sleep. Deciding to let some steam off, her left hand found her unsurprisingly wet pussy, while her right went to rub her swollen belly. Getting additional mental stimulation from the fact that she was pretty much anally pregnant, it didn't take her much rubbing to reach a quick orgasm, calming her nerves and letting her sleep, finally. Her body was demanding more and more.
She awoke rested the next day, if somewhat horny. She seemed to be in a permanent state of arousal these days, amplified even more by the slimegirl in her ass. Speaking of which, Ryiah seemed to be active this time, moving around in her bowels, possibly trying to tell her that she wanted out. Deciding to test her theory, Beth left her plug in, imprisoning the slimegirl inside for the time being. She dressed up in her usual clothes, smiling as the waistband of her skirt squeezed her slightly bloated belly.
Riding to Stretchington only took a few hours. Beth decided to help Riyah, but only after she finished her own mission. The plan was to eject the slimegirl somewhere hidden in Stretchington, letting the blue girl wait somewhere safe - her kind was not necessarily welcome in the city. Her passenger didn't get the memo however, and tried to actively escape her fleshy prison. Beth could have none of that - birthing a slime (anally at that!) on the middle of the street would have been ridiculously embarrassing, and possibly dangerous. Riding past the now well-known hourglass-shaped guards, she let her entire weight rest on her plug, preventing any unwanted breakouts before the time came.
She was happy this time that the streets were mostly deserted. She didn't want to attract any unwanted attention as she finally found a hidden alley between two fancy mansions. She slid off her horse, then quickly slipped between the buildings, preventing the plug (and the slimegirl) from erupting between her buttocks with her hands. When she was sure no one was around, she let go.
The feeling as the huge metal plug shoot out of her ass, followed by a frightened slimegirl was hard to describe. It was devious, liberating and lewd at the same time. Ryiah was far from careful this time, she pretty much exploded out of Beth's butt, regaining her usual size in a rapid rate, giving her temporary home an additional stretch. Beth couldn't savor the feeling for long tough - Ryiah was visibly panicking, and was trying to ooze towards the streets, not even waiting for legs to properly form.
Beth didn't have any really good options at this point. It dawned on her that she should have consulted with the slimegirl before releasing her in the middle of the city, but it was way too late for that now. Since the Ryiah herself told Beth that she was not welcome here, and would probably get imprisoned as soon as she got caught, Beth did the only thing that could prevent that. With a quick spell, she froze the slimegirl solid.
She sincerely hoped that the freezing would cause no permanent harm to Ryiah - she did it to prevent an even worse scenario, after all. Most people seemed to only suffer from weakness and nausea after melting out - it certainly seemed a better option than being thrown into prison, or worse. Beth knelt besides the frozen oozegirl to examine her more closely, surprised by the fact that even the simple act of kneeling opened her ass so much that she felt a breeze in her insides.
Ryiah looked amazing the way she was, like a blue-tinted glass statue. Her legs were not formed yet, the freezing spell captured her in a state where her lower body was just a blob. From the waist up, however, she was perfectly formed, including her pretty face and monstrous boobs. She was quite a sight.
Beth's plan was to just leave Ryiah there, finish her own business with Satrin, then come and collect the (hopefully) warmed up slimegirl. She just hoped that the googirl will wait for her return. She quickly replugged herself, getting comfort from the way the wide, warm metal spread her insides, then adjusted her clothing. She wanted to look presentable for Satrin.
Finding her employer's mansion was easy, it was the biggest one around. The guards let her in without any hassle this time, either remembering her from her last visit, or just respecting the official sign embroidered on her clothing.
Beth was about to ask the guards for Satrin when she heard the master's cool and collected voice. He was talking to a young woman, who Beth guessed was his daughter. When he realized Beth was around, he turned his full attention to her.
"Took your sweet time, didn't you? Well, no matter, the important thing is that you succeeded. You did, didn't you?"
Beth could only nod.
"Good. Follow me, I have a few things to discuss." Not even waiting for her answer, he retreated to his personal chambers, leaving his frustrated daughter hanging. Beth did not loiter around, she followed him as fast as she could - she did not want to meet any more members of the Coast family, Satrin was already hard to manage. She entered the room.
Satrin was already waiting for her, sitting in a chair, and a padded table stood before him - something like a massage table.
"Give me the letter you were sent for, then lay down here. I have many things to do, I want to get this over with."
Beth did as she was told, handing him Gothar's letter with her right while making sure the recently found black pearl was in her pocket with her left. She really intended to keep her plug, and it was her best bargaining chip.
Satrin briefly examined the envelope, making sure the seal was unbroken. Satisfied, he motioned for Beth to lay down on the table. "Let me read this real quick. Make yourself comfortable and your ass available."
Beth could not help but blush - Satrin's nonchalant way of talking about her butt was embarrassing her. Still, she did as she was told - she lay down on the table, then hiked up her skirt to allow access to her backside. She felt terribly embarrassed, but she had little choice in the matter. At least she felt physically comfortable, the table was made with busty females in mind.
Satrin only took a few minutes to read the letter. When done, he turned his full attention to Beth - or, more precisely, to her fully packed butt.
"You seem to have changed the bottom part of my uniform. Trying to hide your recent modifications, hm? Why are you embarrassed to show it off when you seem to have no problem wearing your old shirt, showing a mile of cleavage? Well, no matter, it's none of my business anyways."
Beth couldn't help but chuckle - Satrin's standards, or rather, Stretchington's standards were totally different from hers. A large, shapely bust was something to be proud of while a monstrous butt plug was more like a secret shame. And her cleavage was far from daring, at least by Multipedete standards. Still, she saw no point in mentioning that. Her musings were cut short when Satrin removed her thong in a casual manner.
"That undergarment is just ridiculous at that point. I guess it still covers your genitals, but it breaks the immersion of your butt. Such a plain clothing should not be allowed to ruin the sight of this art. And... Would you look at that? You are way ahead of schedule. How come the plug is this size already?"
There was something really annoying about the way Satrin talked. Like Beth was not a living person, more like a piece of art - clay that could be (or rather, already has been) shaped. Still, Beth knew better than to take it personally - that attitude probably came with the job.
"I don't know the specifics. Gothar seemed to mess something up when he undid his own enchantment. I also met with a kitsune on my way there, who... sucked out most of my energy, and probably the ruby's as well."
Satrin nodded at that. "Yes, that would explain it. Gothar is nowhere near my level, but he doesn't make mistakes often. Props to you, you seem to have no trouble wearing even this advanced size. Bear with me while I dispel my enchant and examine your hole. It will only take a moment."
Beth felt Satrin's thin fingers grasp the toy nested between her buttocks, then felt them remove it with surprising ease. He worked with speed and precision, but he was still careful not to cause any pain or discomfort. Beth wondered how many asses this guy has plugged before.
