Things had been business as usual since my sister and I had our toilet adventure. As usual and also better...because she had been even more kind in several situations...and I the same back then.
At some point, my mother may have wondered what had happened between us, but let it go.
After all, things were really good. So, despite mom curiosity, she hadn't dug any more into it.
Now we were out at our country house all four of us. Or right now there were three of us, because dad was in town fixing things, and he was going to come out tomorrow again. So it was mom, my sister and me.
We ate pretty early in the afternoon...had just finished eating, and felt both of us a bit mischievous so we ran around the lawn in our swimwear chasing one another. A bit fun and very cozy to get hold of each other and petty wrestling.
We were thirsty from chasing and went into the house drinking water. And when we stood there by the tap, we saw the boxes of wine on the counter, that dad was now, among other things, in town to buy new ones.
Without hearing with sis, I drank the glass with water, and filled it up half with wine.
Took a couple of sips, and held out to my younger sister, who doubtfully took the glass...but slowly took a couple of sips, her too.
Back on the lawn, chasing. Although we were tired and a little dizzy from the wine...so it became less running and mostly wrestling now. And it certainly wasn't wrong, maybe embarrassing...but far from wrong.
The embarrassing thing was that when my sister straddled and tickled me, it was impossible not to poke her with my pretty hard dick. It often got hard when we wrestled, but mostly I could make sure she didn't notice it so clearly...but when she sat on me in a swimsuit, with my dick visibly hard in her crotch...like now, then it became embarrassing. Even more so of the top sticking out a little outside the swim trunks.
We slowed down our banter completely...paused and she looked strict and concentrated down her crotch.
Then she moved forward a bit...and back.
"Is your dick so hard because it likes when we wrestle and me sitting like this? You know it's wrong to think that way about your sister, right? It's your girlfriend who should make the dick hard."
"It's a bit difficult to control it sometimes. And right now, you're more of a good-looking girl in a nice swimsuit...than my little sister. You're very hot and sexy, sis.
This was the wine ruling, otherwise she wouldn't have done this, but she moved back a bit, and picked up my shorts...looked straight at the dick.
Looked at it and was about to take the other hand around it, when there was a noise, could be mom. So my sister dropped the shorts down quickly and got off me.
When she let them go, she let them down so they flicked at me and I moaned a little.
"Oh, I'm sorry bro. But I can make it up to you, because I want to see more of your dick who likes his little sister so much."
While she said the last thing, she stroked her hand outside my swim trunks.
"Let's go up to your room or my room...and sneak past the kitchen, so we can have another sip of wine."
What a naughty girl my little sister was, I thought, and didn't have time to think anymore before she moaned and pinched her legs.
"Does your stomach hurt, hard to poop again?", I was thinking a little hopeful of helping out again.
Not minding our age that both of us very well could do these activities ourselves.
"Well, not stomach ache. I tried to poop yesterday, and this morning...but it's big. And it hurts when I squeeze, trying to get it out. And I'm afraid it's going to hurt a lot. Scares me..."
"Do you want us to do the same thing again, that I put my finger in your poopy butt, to help you?"
"I don't know...now mom's here. And the poop feels closer now...you'll be messy if you put your finger up my ass."
"I like you, sis, and...we both like you lower down too. And I'd like to put my fingers in your ass. If they get messy from being inside your butthole...well, then I guess I'll just have to wipe them off and wash."
"I'd love to help you now, too, and I don't care that we're messing around, at all.
...and we can be in the outhouse...what luck or...?"
We had an old outhouse with a working 'stinky dry toilet', that dad was caring for.
Cared for mostly because he used to be able to sit there alone, and not be disturbed. Or that the usual toilet in the house was occupied for hours. If only the damn mosquitoes could disappear, he commented in swearing.
But now...if we went there...
Let's go over there, come on. Dad won't be here until tomorrow. And mom uses the toilet inside.
