Marilyn stroking my cock was the upright thing I ever felt. I could n't wait for the side by side time we had the star sign to ourselves.
Well, I did n't induce to hold off very long. Two solar day later our parents announced that they were going to a clientele meeting Dad had on the Dame Rebecca West seacoast and that Marilyn and I would be staying home. Oh darn ...
I had just gotten my driver 's permission so it was my job to necessitate Mom and Dad to the airport.
'' takings caution of your sister, '' Dad said, `` and no parties ! ``
A little voice in my head said, `` No problem ! ``
When I got home Marilyn was out laying in a shay by the syndicate. She was wearing a thong bikini that covered her private percentage, but just barely. The top was two little dapple of textile that hid only her nipples. The tail was even minor.
'' Where did you get that, '' I asked ? I could n't lead 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 suffice she looked at my privates and smiled. `` I think you do. ``
There was no denying that I liked it. My dick was already self-coloured.
'' So, what have you got planned for today ? '' I said topic of factly.
Marilyn shrugged. `` I do n't know. I thought about going to the mall with Becky or maybe a movie with sallying forth. ``
My meat sank. I was really hoping for another handjob.
She pushed her deoxyephedrine back up and layed her head back on the chaise.
'' Or maybe I 'll just stay here and watch you jack your cock. ``
Yes !
'' That sounds like fun, '' I said then added, `` It would be even improve if I could see your boob while I did it. ``
'' Hmmm, you think so, '' she said through a smile.
My putz twitched in my knickers.
'' wellspring, 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 bikini top letting it fall away.
Her tit were everything I had imagined and more. They were perfectly symmetrical and her pap were just as perfect tense pointing straight ahead. From the looking at of it I thought she was enjoying this a little Sir Thomas More than she was letting on.
'' Okay, start jerking it. ``
I took my cock in my hand and began stroking while I stared at Marilyn 's consummate breasts. She, in turn, stared at my cock which was already oozing a well-defined sticky liquid.
'' Come closer, '' she said. `` I want to see it up close. ``
With my shaft and balls sticking out of my jeans I walked over to where Marilyn was sitting. To my surprise she reached out and took my hand off my swollen mother fucker and spit into it.
'' There, that will make it slicker for you. ``
At the same time she took my egg in her manus.
'' Let me agree these out of the way, '' she said with a smile.
As much as my sister was trying to pretend this was a big prank for her she was also beginning t squirm 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. Shit. I thought I just blew it, but to my unadulterated surprise she untied the thong and let it fall to the floor.
Marilyn 's pussy had a strip of drear hair down the midriff. The rest had been shaved so as not to hang out the side of the lash. She sat back down.
'' Now what, '' she asked ?
My hammer was straining for assuagement and I had to stop jerking it least I blow my load and end the whole thing.
'' Ummmm, can I see your clit ? ``
Without a word she placed both script on the face of her pussy and spread her sassing. And there it was, the summit of every man 's desire. And as I stared at it I saw it get. She was as steamy as I was. Then without me even asking she began to rub her clit with her two index fingerbreadth.
'' I 'm warning you, '' she said, `` sometimes I pee when I come. ``
I could hardly brook it, but I held off cumming to let her catch up.
Marilyn squeezed her clit between her finger's breadth and jerked it up and down while systematically pushing her hip into her hands. I hardly moved my hands on my cock for awe of cumming right then.
Then suddenly my sister pushed her pelvis 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 have it land on my cock and balls.
As her pee drenched my hands she moaned out, `` follow on my tits ! ``
I stroked my stopcock hard for just a few irregular when the showtime current dead reckoning out bypassing her tits and hitting her squarely in the face. She did n't appear to mind in the least, but continued pissing ; her piss mixing with my cum.
When Marilyn finally stopped peeing she gave a few more grunt and fell back on the recliner. The last of my cum was dribbling out of my cock as I collapsed in the chair next to her.
After a few minutes we caught our intimation enough to wait at each other. We began to laugh.
I wondered where this was all leading to when Marilyn said in a very soft voice, `` I wonder how that matter would experience stuck in this thing ? '' she pointed to her pussy ...
