...my sister said okay. And now we sat there and talked about all sorts of things. I'm on the floor leaning against the wall and she's on the toilet. We've always had an easy time talking, and same now, all and no talking, plus a little more moaning and whining that she didn't want it like this.
When we've talked a little bit more and my sister's been alarming a little bit more...I came to think of one thing. Had heard someone say at school or at training I think, it was enough to have a finger up your ass...that can get most things going. And I'd just told her that as naturally as anything else we talk about.
And thought that, so... well, put your finger up and we can watch a movie and eat popcorn later.
I didn't think of anything sexy about this, right then. Just thought we should finish in here and see the movie.
"You can forget I'm putting my finger up my butt, where disgusting poop comes from. Forget that!"
"Then I guess I'll just have to put my finger up your disgusting ass, so we'll get out of here sometime."
"No, I really don't want to. And neither do you. Dirty ass that smells bad. No, let's talk instead and see if anything happens."
But now I was getting pretty tired of this, and I wanted to do other than hear her beeping sounds about her stomach. So I got up and started walking towards the door. Said I'd go play until she's done here. She didn't want that at all, wanted my company, and looked really pitiful when she said, "But put your finger up my ass then, but don't go... please."
Still, none of us had thought anything special about this, except for the filthy place where poo came from then. So my sister quickly turned around on the toilet, and sat there with her butt out.
Annoying how girls always are so good at hiding everything we guys want to watch. And she did now too, so I told her to bend over so I could get to it. A little more forward-leaning, I reached and took my index finger and put it against the hole. She jumped and clinched her butt cheeks. A little annoyed with what she was doing, I told her she could finger the hole up front while I was fingering the back. Then we both were busy on each side.
She didn't answer that, just slid back again...so the butt cheeks opened up and I could put my finger back.
When I massaged for a while with my finger outside and was going to poke it in, it didn't go that easy, too dry. So I took the finger and put it in my mouth, and back for massage and push in a little. Same again, a couple of times... finger a bit inside her butt and then back in my mouth. Then I noticed the smell...the smell of sisterly butthole and sisterly ass. And it started growing quite a bit in my pants, got really crowded in there.
Not just me who had reacted to the fingering in the back. My sister too, she was actually rubbing her front pretty energetic. Damn, I got horny. So I put my pants down a little bit so I could surreptitiously jack myself at the same time.
Now I hadn't fingered her for a while. While I pulled down my pants and also looked at her caressing and massaging herself, so she turned around a little bit and said, "What are you doing, why did you stop poking my butt? I think it feels pretty good, or I mean...think it feels better with the blocking, that it might help. Poke more with your finger in me."
