Sister finds my toys pt3 (revised)

I awoke the next morning to the sound of my phone ringing. It was my sister Carol. Carol is two years older than Chris and six years old than I. Her news floored me.
I lay in bed, wide awake trying to decide if I should tell Chris before or after we did the deed. I decided to wait until after.
As a kid growing up in a rural New England town my folks had a puritan outlook on sex. In fact, it would have been difficult to define sex in our house at all, because it appeared to be non-existent. No word of sex was ever mentioned. Not the slightest inkling of sex; not even to accept that there was a difference between boys and girls. Even the word fart was not allowed. Fart was a vulgar swear word.
I had always assumed that my sisters, all four of them, subscribed to this sort of thinking and that they carried it into their adult lives. Then, along came Chris to blow that theory out of the water.
Carol’s call had me wide awake. Since sleeping in was past being an option I dragged myself out of bed and headed for the kitchen. I didn’t bother to get dressed. Clothes were no longer an issue with Chris and me. I got the coffee started.
A few minutes later Chris joined me.
“You’re up kind of early aren’t you?” she said. She was wearing panties, but no top. Her big, beautiful tits were there for all the world, or at least for me, to see.
“Yeah, I decided to get an early start today.”
Chris poured herself a cup of coffee, sipped a little bit, then sat down across from me.
“What’s so important that Mr. Stay-in-bed got up before me?”
Looking at my sister sitting across from me with her chest completely exposed was already having a real effect on my lower anatomy. My dick was start to twitch.
“I thought maybe we’d get started on your promise from last night.”
Even though Chris and I had no secrets anymore I still found it weird to use sexual slang when speaking to her. Obviously she didn’t suffer from the same problem.
“You mean when I promised that we’d fuck today?” she said. She had a serious expression on her face, but couldn’t hold it for long. She started to laugh.
“Little brother, after all that’s happened are you still unsure of saying, ’Fuck?’ Boy, Mom really had a big influence on you, didn’t she?”
Okay, I could play the game. Let’s see how she liked it.
“No, I’m okay with saying ‘Fuck’. I was trying to be polite. Let’s skip breakfast and go fuck.” I would never admit it, but it still felt weird saying fuck to my sister. And she knew it.
“Cool,” she said. “The way you ate my clit last night has me really ready to fuck your brains out. And don’t forget, you promised to show me how to fuck myself with the Rabbit toys. Oh yeah, and when we fuck I want to do it in front of your bedroom mirror so I can watch your big cock slide in and out of my wet cunt”. She stared at me grinning.
“Okay, okay you win. Mom’s rules are imbedded in my brain. Good grief. Where did you learn to talk like that?” I said.
Chris got up and came over to my side of the table. She looked down at the tent pole in my underwear.
“Seeing that,” she said pointing to my already hard cock, “has enlightened me to the finer points of sex to include, but not limited to, dirty talk. Now let’s go fuck.”
When we got to the bedroom Chris laid down on the bed. Her big tits fell, one to each side of her chest. Her areolas stretched a bit and her nipples were already hard. I was beginning to think I had created a sexual monster. But hey, monsters need love, too. I went to the closet and got the Rabbit toy.
“Okay,” I said, “this is how it works.”
I plugged the toy into the wall socket and pushed one of the little buttons on the control handle. The rubber dick part with the clear plastic in the center that showed the beads began to whir. The dick at the tip started to move in a circular rotation while the beads in the clear part bounced all around.
“Put your hand on it and feel the beads,” I said.
“Chris put her hand on the toy. “Oh wow! I can feel the beads like little, I don’t know what, but they feel like they just might do a good job on Miss Kitty.”
“Miss Kitty,” I said with raised eyebrows? “Sounds like a little of Mom is in you, too.”
I push the next button and the rabbit part of the toy started to buzz. “Feel that part,” I said.
Chris put her finger on the rabbit.
