(Hello. I've been away for a while, mostly working on short forms as tricias-captions on Tumblr. But they decided what they decided and I guess I'm back. Longer form requires less attention-deficit disorder. :-) So, I'm not sure what will come of it. Anyway, this is medium-length fiction for me. Hopefully one of a totally unconnected series. -Tricia, Feb 2019)

It'd been such a long time since my older sister and I had gone shopping together that I was delighted she suggested it. We kissed our husbands goodbye for the day, and Anne told little Melanie to behave for Daddy. Then we both got into her Jeep Cherokee and drove to the mall. It was good to have the time on the drive to catch up, I just forgot about everything else (and it's amazing that I forgot about _that_) and fell into old habits.
Things were great until we both chose a couple of dresses in Nordstrom's and took them into a changing room together. I lifted my dress over my head and Anne gave a sort of quiet fake whistle. "Woo hoo, Sis," she commented, "nice undies!" I was wearing a matching set of dark green push-up bra and thong from V's Secret. "I don't get to wear anything like that any more." She had on a front-opening pink bra on top and and boring old white cotton bikini panties down below.
"We should def go and buy you something new then. You deserve some. My gift," I said.
"You don't need to do that, Claire," Anne smiled.
"I know I don't, but I want to." I was glad I didn't have to tell her the story behind all my matching undies.
I turned to the hook where my try-on dresses were and reached for one. I pulled it on while Anne's pulled on hers and we traded comments when we turned to look at each other. I was definitely not going to buy mine, but Anne hers might work.
Then turned my back on her again, took off the first dress and reached for the next dress to try. Somehow, I managed to fumble it and dropped it on the floor. No matter, I bent over and picked it back up again, feeling that extra deepness from my butt plug that I always feel when bending. But I was used to that and didn't give it any thought.
But I should have been more cautious.
"Um, Claire?" Anne said with a strange tone to her voice.
"Yeah?"
"What's that shiny thing in your butt?"
Oh crap! I tried to pretend it wasn't there. "What do you mean?" I started to open the zipper on the next dress.
She was having none of it. She grabbed the back of my thong and pulled it away from me. "Oh my god! You have a green jewel sticking out of your ass!" Busted. Fuck.
"It's, um, a butt plug." I was very glad we were the only women in the changing area.
She pushed on it, giggling, I shivered visibly, making her giggle more. "What's this? Some kind of sex game with Paul?"
"Um, no. Paul's like totally lost interest. I think he's fucking some woman from his office."
"Oh, I'm sorry — though I know the story. So, what you do this as a sex game yourself? Or are you stepping out too with some guy?"
"Not some guy..." I was sure my face was bright red.
She looked me right in the face? "So, it's a woman? Claire? I never thought you were into women."
"It's Paul's sister," I said very quietly.
"Oh my god! Donna?"
"No, Devorra." Donna was Paul's biological sister. Devorra was adopted, African American.
"Oh my god. But that explains a lot." I wasn't sure what she meant, but I didn't really want to know.
"She's very dominant. She turned me out and made me her slave a week before Paul and I got married."
"Oh my god...."
"You are saying that a lot."
"So, she's your..."
"Mistress, yeah."
"And she makes you..."
"Do lots of things, yeah."
"Like?"
"Like the butt plug, which has to match the undies, which have to match each other. She's why I don't shave my underarms. She's why I do shave my cooch."
"You shave? Let me see!" I started to say no, but my sister just reached out and grabbed my thong and pushed it down and over my hips, making it fall to my ankles. "Oh, Sis, nice! And it looks smooth," she reached out and quickly ran her fingers over my mons, making me both shiver in pleasure and blush redder in embarrassment. "You must shave often."
"Every other day, no matter what's going on."
"Wow. Does she make you go down on her pussy?"
"Um, yeah. And her ass." I wasn't sure why I was volunteering that.
"We gotta get out of here and go someplace we can really talk. Get dressed!" It was a command, pure and simple, and Devorra had shown me how susceptible I was to a strong woman's commands. I bent to pull up my thong, but Anne stopped me. "Oh no, you little submissive slut of a sister. Take those off. In fact... she quickly pushed down her cotton panties and took them off before she pulled her original dress back on.
