Marilyn stroking my cock was the best thing I ever felt. I could n't wait for the next time we had the star sign to ourselves.
Well, I did n't have to wait very long. Two day 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 mend ...
I had just gotten my device driver 's permit so it was my job to take Mom and Dad to the airport.
'' Take guardianship of your sister, '' Dad said, `` and no party ! ``
A little voice in my head said, `` No problem ! ``
When I got home Marilyn was out egg laying in a chaise by the pool. She was wearing a thong bikini that covered her common soldier parts, but just barely. The top was two little while of fabric that hid only her nipples. The bottom was even smaller.
'' Where did you get that, '' I asked ? I could n't take my eyes off of her.
She pulled her sunglasses down just far enough to await over the top of them. `` I bought it a few hebdomad ago. Been hiding it from Mom and Dad. Do you like it ? ``
Before I could answer she looked at my crotch and smiled. `` I think you do. ``
There was no denying that I liked it. My dick was already square.
'' 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 promenade with Becky or maybe a movie with Sally. ``
My affection 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 last out here and watch you jack up your cock. ``
Yes !
'' That sounds like fun, '' I said then added, `` It would be even estimable if I could see your tits while I did it. ``
'' Hmmm, you think so, '' she said through a smile.
My cock twitched in my pant.
'' fountainhead, call for it out and let 's see what happens, '' she said.
'' Out here, by the kitty ? ``
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 tits were everything I had imagined and more. They were perfectly symmetrical and her nipple were just as perfect pointing true ahead. From the tone of it I thought she was enjoying this a little more than she was letting on.
'' okeh, start jerking it. ``
I took my turncock in my hand and began stroking while I stared at Marilyn 's perfect breasts. She, in number, stared at my stopcock which was already oozing a clear sticky liquidity.
'' Come closer, '' she said. `` I want to see it up close. ``
With my tool and clod sticking out of my jeans I walked over to where Marilyn was sitting. To my surprisal she reached out and took my hired man off my swollen prick and spit into it.
'' There, that will make it slicker for you. ``
At the Saame time she took my formal in her hand.
'' Let me hold 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 wiggle in her sit.
I decided to go for broke. `` I bet this would be even more fun if I could see your pussy ! ``
Marilyn let go of my testis and stood up. Shit. I thought I just blew it, but to my utter surprisal she untied the thong and let it accrue to the floor.
Marilyn 's pussy had a cartoon strip of iniquity hair down the middle. The rest had been shaved so as not to hang up out the side of the thong. She sat back down.
'' Now what, '' she asked ?
My cock was straining for succour and I had to stop jerking it least I blow my shipment and end the whole thing.
'' Ummmm, can I see your clit ? ``
Without a Bible she placed both manpower on the side of meat of her pussy and spread her lips. And there it was, the superlative of every man 's desire. And as I stared at it I saw it grow. She was as ruttish 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 stomach it, but I held off cumming to let her catch up.
Marilyn squeezed her clit between her fingers and jerked it up and down while systematically pushing her pelvis into her hands. I hardly moved my men on my cock for fear of cumming right then.
Then suddenly my sister pushed her hips into the air and moaned, `` I 'm cumming now ! ``
As she spoke she began to pass water. I wonder now if she had planned it because where I was standing she was capable to pee a long arc into the air and get it land on my cock and glob.
As her pee drenched my workforce she moaned out, `` Come on my tits ! ``
I stroked my cock hard for just a few secondment when the first base stream shot out bypassing her tits and hitting her squarely in the fount. She did n't seem to mind in the least, but continued peeing ; her peeing mixing with my cum.
When Marilyn finally stopped peeing she gave a few more grunt and fell back on the reclining chair. The endure of my cum was dribbling out of my stopcock as I collapsed in the chair next to her.
After a few bit we caught our breathing space enough to look at each early. We began to express joy.
I wondered where this was all leading to when Marilyn said in a very flabby vocalism, `` I wonder how that affair would feel stuck in this affair ? '' she pointed to her pussycat ...
