I woke up and looked at the grey light of morning filtering through the windows. The sun wasn't quite up which meant that Mom and Dad would be asleep for a while longer. I felt Paris curled up behind me, one arm draped over my hips. I felt her naked body pressing into my exposed skin and sighed. I grabbed her arm, gently. I wanted to enjoy this. To relish in it. I felt her free arm snake under my body and pull me close to her so that both her arms were wrapped around my midsection.
"You awake yet?" She whispered.
"Shhhh," I whispered. "If I'm dreaming, I don't want to wake up yet."
She pressed her body into mine and squeezed against me. "Not a dream."
I rolled on the bed to look at her smiled. Her hair was still a mess from last night, as I'm sure mine was, but even mussed and looking every bit as haggard from a not-quite-full night's sleep, she looked more amazing than ever.
"Hey Baby Phee," She said.
"Hey there, Big Sis."
She pushed some hair out of my face. "Have a good night?"
I couldn't put together the words to describe how amazing it was. "The best ever."
"Any regrets?"
"Only that we didn't do this sooner."
She smiled and kissed me. It wasn't the soul crushing kiss from last night, but it still made me hyper-aware of our naked bodies pressed so closely together. Well, almost naked bodies. I was still wearing the red bralette from the previous night, and I felt our combined cum dried and covering my belly and chest.
"Can I ask you something?" Paris said.
"Anything."
"When was the first time you fantasized about me?"
"Ages ago. You had gone out on a date with Tommy Borren and left a bunch of your clothes laying around. I went into your room to look for something and just saw them there. That was the first time I tried on your clothes too. I imagined you finding me like that, trying on your clothes and teaching me to be your little sister, before deciding that little sisters needed to learn to kiss."
"That's a while back," Paris said. "That's before," she waved her hand in a vague gesture, "this."
I nodded. "Yeah." I grabbed her hand and held it between us. "And you? When did you first fantasize about me?"
"In college. My roommates were talking about fetishes and weird turn ons after drinking too much. One of them said she always got so wet for her brother. She knew nothing would ever come of it, but it didn't stop her from fantasizing. And of course, I started to fantasize then."
She looked down at the bra and ran one finger along the edge. I shivered at the touch.
"And the clothes?"
I shrugged. "As long as I can remember. Anyone else in the family?" I asked with a half grin.
"Everyone else. You?"
I nodded. "Everyone else."
We giggled and snuggled together a moment longer. "How much do we tell Mom and Dad?" I asked after a moment.
Paris shrugged. "We don't have to tell them anything. For now this is ours. Just us. And we should get cleaned up before they wake up. I need a shower and so do you."
I pointed to my wash basin by the window. "I'm all set. Mom is used to me cleaning up in here."
Paris got out of bed. I stared at her naked body while she put on her bra and thong from the previous night. She looked magnificent, still half covered in my dried cum and her hair an absolute mess.
"You're beautiful," I said. "Paris, do you think we could sleep together again tonight? Not fool around, not if you aren't up for it, but just, sleep together?"
"Yeah, but in my room. Your bed is too small."
That day I wore a dark brown thong and matching bra. My nipples seemed even larger and puffier than the previous day and I was worried that they would be oddly visible if I didn't put on something to hide them. I put on a pair of jean shorts from the collection as well since none of mine seemed to fit anymore, and a simple dark t-shirt that would be sure to cover the bra. I didn't realize that I had never taken the butterfly necklace off and it nestled itself over my shirt and bra right where my cleavage should have been.
Paris wolf whistled at me when I entered the kitchen for breakfast. It was an expression I was hard pressed not to emulate. She was dressed almost identically to me, except that she wore a tanktop that exposed her lack of bra quite clearly.
"Stop that," Mom said. She looked at me and nodded approvingly. "At least the clothes fit you. I'm sorry there isn't anything more your style, but you look good Baby Phee." She turned to Dad. "Don't you think so Dear?"
Dad I realized, had been staring at me the moment I entered the room. "Yeah. It looks good on you kiddo."
The morning passed normally. Paris and I were trying not to flirt with each other. I could tell when she was thinking of last night, or some other fantasy because she got a glassy look in her eyes and whatever she was working on took a little longer than normal. For my part, I spent a lot of time hoping that my hard on didn't pop out of the shorts I was wearing. They were women's shorts, shorter than what I normally wore and made to hug my ass and hips. My bulge would pop out the top if I let it get to hard pointing upwards, and it would absolutely pop out the bottom of the leg if I let it get too hard going that way.
After lunch, Paris came over to me and leaned down next to me while I was weeding. "Nice thong, Baby Phee," she whispered into my ear. "Showing it off on purpose?"
My eyes went wide. I looked around in a panic.
