Marilyn stroking my pecker was the effective matter I ever felt. I could n't wait for the next time we had the business firm to ourselves.
Well, I did n't have to waitress very long. Two days later our parents announced that they were going to a business meeting Dad had on the West coast and that Marilyn and I would be staying home. Oh darn ...
I had just gotten my driver 's license so it was my job to take Mom and Dad to the airport.
'' issue forethought of your sister, '' Dad said, `` and no company ! ``
A little voice in my mind said, `` No problem ! ``
When I got home Marilyn was out laying in a chaise by the pool. She was wearing a thong Bikini that covered her private parts, but just barely. The top was two little spot of fabric that hid only her mammilla. The behind was even smaller.
'' Where did you get that, '' I asked ? I could n't shoot my eyes off of her.
She pulled her sunglasses down just far enough to look over the top of them. `` I bought it a few weeks ago. Been hiding it from Mom and Dad. Do you like it ? ``
Before I could serve she looked at my fork and smiled. `` I think you do. ``
There was no denying that I liked it. My prick was already substantial.
'' So, what have you got planned for today ? '' I said matter of factly.
Marilyn shrugged. `` I do n't know. I thought about going to the mall with Becky or maybe a movie with Sally. ``
My pith sank. I was really hoping for another handjob.
She pushed her glasses back up and layed her head back on the chaise.
'' Or maybe I 'll just persist here and view you jack your dick. ``
Yes !
'' That sounds like fun, '' I said then added, `` It would be even better if I could see your breast while I did it. ``
'' Hmmm, you think so, '' she said through a smile.
My cock twitched in my pants.
'' Well, take it out and let 's see what happens, '' she said.
'' Out here, by the pool ? ``
Marilyn looked around. `` Why not ? It 's just you and me out here. '' With that she reached behind and untied the two-piece top letting it fall away.
Her bosom were everything I had imagined and more. They were perfectly symmetrical and her mammilla were just as arrant pointing unbowed ahead. From the looks of it I thought she was enjoying this a little more than she was letting on.
'' Okay, start jerking it. ``
I took my tool in my hand and began stroking while I stared at Marilyn 's unadulterated knocker. She, in turn, stared at my prick which was already oozing a earn embarrassing liquid.
'' Come closer, '' she said. `` I want to see it up close. ``
With my dick and orchis sticking out of my denim I walked over to where Marilyn was sitting. To my surprise she reached out and took my hand off my tumefy prick and spit into it.
'' There, that will make it silky for you. ``
At the same prison term she took my musket ball in her hand.
'' Let me apply these out of the way, '' she said with a grin.
As much as my Sister was trying to pretend this was a big joke for her she was also beginning t wriggle in her sit.
I decided to go for broke. `` I bet this would be even more fun if I could see your pussycat ! ``
Marilyn let go of my balls and stood up. bullshit. I thought I just blew it, but to my give tongue to surprise she untied the thong and let it return to the floor.
Marilyn 's kitty-cat had a striptease of dark hair down the middle. The rest had been shaved so as not to hang out the side of the thong. She sat back down.
'' Now what, '' she asked ?
My stopcock was straining for reliever and I had to stop jerking it least I blow my consignment and end the entirely affair.
'' Ummmm, can I see your clit ? ``
Without a word she placed both hired hand on the sides of her pussy and spread her lips. And there it was, the pinnacle of every man 's desire. And as I stared at it I saw it spring up. She was as randy as I was. Then without me even asking she began to rub her clit with her two index fingers.
'' I 'm warning you, '' she said, `` sometimes I pee when I come. ``
I could hardly fend it, but I held off cumming to let her enchant up.
Marilyn squeezed her clitoris between her fingers and jerked it up and down while systematically pushing her pelvic arch into her hands. I hardly moved my hands on my cock for fear of cumming right-hand then.
Then suddenly my sister pushed her articulatio coxae into the air and moaned, `` I 'm cumming now ! ``
As she spoke she began to piss. I wonder now if she had planned it because where I was standing she was capable to piss a long arc into the air and suffer it land on my cock and nut.
As her pee drenched my hands she moaned out, `` occur on my tits ! ``
I stroked my cock hard for just a few seconds when the first stream shooter out bypassing her mammilla and hitting her squarely in the face. She did n't seem to mind in the least, but continued pissing ; her piss mixing with my cum.
When Marilyn finally stopped peeing she gave a few more grunts and fell back on the reclining chair. The live of my cum was dribbling out of my cock as I collapsed in the chair next to her.
After a few second we caught our breathing space enough to bet at each former. We began to express mirth.
I wondered where this was all leading to when Marilyn said in a very sonant vocalisation, `` I wonder how that thing would find stuck in this thing ? '' she pointed to her snatch ...
