Kira walked through the wide mall corridor, not believing her luck. Her asshole of a boyfriend was now her slave to do with as she liked, and she sure had some fantasies involving him.... She walked into a shop she had visited only a couple of times before. It was called "Magnolia's House of BDSM". It was a sex shop devoted to the more extreme forms of pleasure. Kira had poked around in the shop, never too serious, but it had piqued her interest, and she was now thinking she might like making her sex life a little more interesting.
Her thoughts were interrupted by a shop attendant. "Can I help you find anything?"
The attendant was a small, mousy girl with glasses. Honestly Kira was surprised to see someone like that working in a shop like this.
"Umm," Kira stammered, "Do guys have butt plugs, uh... that help expand what the ass can take?"
"Sure do! Follow me!" The girl, whose name tag read "Celina", led Kira to a nearby aisle.
Celina picked up a box and handed it to Kira. The box contained a set of 12 glass butt-plugs, each roughly turnip-shaped and increasing in diameter. The smallest was 3/4 inch and each butt-plug was bigger in size by about 1/4 inch, leaving the largest at just under 4 inches in diameter.
Celina explained "These butt-plugs are intended to be used one after the next. As the ass gets used to one you can increase the size up to the next one in line, until your ass can take the largest one. The glass is special too and expands slightly in the presence of heat. So the wearer's body heat will cause it to expand and gradually stretch the rectum.
Kira looked at the price: 200$. She had a credit card... it was worth it. "I'll take it," she said.
"Excellent," said Celina. The two went over to the counter and began checking out. "Would you like me to assist you in putting the first one in now?"
"Oh, no," said Kira. "These aren't for me, they're for my ex-boyfriend."
"Your ...EX... boyfriend?" asked Celina, surprised.
Kira explained. "Yes, he was such a jerk all the time, so I turned him into my slave. These butt-plugs will help me in punishing him, and having a little fun myself!"
"Ah, very good!" exclaimed Celina. "I always like when women dominate men..."
"Incidentally, you don't seem like the type of girl to work in a place like this..." commented Kira. "You're really into this kind of thing, then?"
"Well," Celina explained, "I like strong women; I admire them. I like when women don't take shit from others. I thought this would be a good place to find women like that, so I studied up and learned everything I could about extreme sex and BDSM, even though I'd never really been into those things before."
"I got the job without any trouble, actually," Celina continued. "It surprised me too. At first I thought Mistress Magnolia was going to want me to be a sub to her or something, but she told me that she believes I could make a good sub or a good dom, and I should just do what I like to do. She wasn't going to force me into anything. I appreciate her for that. So rather than be her sub directly, I help her find people she'd really have fun with, and I try to learn everything I can about the trade in the meantime."
"Sounds really nice," said Kira. "You've really got a good thing going then. Say, would you be interested in going to coffee with me? You seem really cool, and you're really cute!"
Celina blushed. "Uh, sure! That sounds great!" she said happily. "I can take my break now, and we can go together... if you like...?"
"Wonderful! Let's do it then!" said Kira.
Celina disappeared into the back of the shop for a moment to let her manager know that she was taking her break, then came back. The two girls headed out into the mall and toward a popular anthro-cafe.
-----
A short while later, Kira and Celina were chatting happily, smiling and laughing frequently and really enjoying each other's company. They discussed Kira's ex-boyfriend and how he had become her slave. They discussed Celina's newfound love for extreme sex. They talked about how they each had had enough with boys, and really wanted to go out with girls now. They talked about some fun fantasies about what they would do with their own slaves. It turned out, their interests were similar.
"I know!" said Kira brightly. "Why don't we get together and have fun? You, me, and my ex? We can have all sorts of fun with him and with each other... It'll be a blast!"
"I thought you'd never ask!" said Celina enthusiastically. "I'd love to! Let's do it tonight!"
"Shall we... consummate the plan...?" Kira motioned toward the private rooms available in all anthro-cafes.
"I'd like to... but, one thing..." said Celina slowly.
"What is it?" asked Kira.
"Well..." said Celina, "I've always wanted to try going anthro, but I never worked up to it. I feel like maybe tonight would be a good time to give it a try."
"Sure, why not?" said Kira happily. "What did you have in mind?"
"Well, see... I'm a very small person," said Celina. "I've always thought that if I would try an anthro-morph, it would be a very big animal. I think the contrast would be fun and interesting. ...Would a big morph be okay with you, Kira?"
"Hey, that sounds like fun! Go ahead, I'll still want to get in your panties, cutie!" said Kira in a sexy voice.
Celina blushed again. "Okay. I'm going to try a hippopotamus-morph! Are you up for that?"
"Absolutely!" Kira replied.
A few minutes later, after Celina had downed her morphing-coffee quickly, there sat an enormous hippopotamus-girl where Celina's tiny frame used to be. She had to have been 7 and a half feet tall, with a belly half that in width and huge bare breasts the size of beach balls. Her feet and hands were flat and her fingers were very short with thick nails, allowing for limited dexterity. Her head was huge and sported small eyes and cute, tiny ears, and her mouth opened wide when she spoke, revealing four enormous canine teeth and a long, wet tong. In the style of anthropomorphs, her dripping pussy was exposed and the scent coming from it overwhelmed Kira with thoughts of pleasure.
"You look divine!" said Kira.
"Thanks!" said Celina, in a surprisingly high, cute voice. "This feels great! Now let's get going; I'm so hot for you right now! I hope I'll be good for you as a hippo-morph."
"I've had anthro-morphs every now and then and enjoyed it," said Kira. "I'm sure you'll be wonderful. I'm the one who's worried about pleasing you; I'm not exactly used to using sex toys..."
"Don't worry; I'll teach you!" said Celina.
The human girl and the hippopotamus-morph girl headed into one of the back lounges and had themselves a night of wonderful lesbian bliss.
