Marilyn stroking my putz was the best affair I ever felt. I could n't look for the next time we had the house to ourselves.
Well, I did n't take in to wait very long. Two daylight later our parents announced that they were going to a business meeting Dad had on the Mae West glide 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 aim Mom and Dad to the airport.
'' takings tending of your sister, '' Dad said, `` and no political party ! ``
A short part in my head said, `` No trouble ! ``
When I got home Marilyn was out laying in a daybed by the pool. She was wearing a G-string bikini that covered her private parts, but just barely. The top was two little patches of cloth that hid only her teat. The bottom was even smaller.
'' Where did you get that, '' I asked ? I could n't choose 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 respond she looked at my genitalia and smiled. `` I think you do. ``
There was no denying that I liked it. My dick was already solid.
'' 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 center with Becky or maybe a motion-picture show with Sally. ``
My kernel 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 check you jack your dick. ``
Yes !
'' That sounds like fun, '' I said then added, `` It would be even better if I could see your titty while I did it. ``
'' Hmmm, you think so, '' she said through a smile.
My turncock twitched in my pants.
'' fountainhead, take 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 teat were everything I had imagined and more. They were perfectly symmetrical and her nipples were just as perfect pointing straight ahead. From the looks of it I thought she was enjoying this a little more than she was letting on.
'' okey, start jerking it. ``
I took my hammer in my bridge player and began stroking while I stared at Marilyn 's perfect boob. She, in turn, stared at my cock which was already oozing a brighten sticky liquid.
'' Come closer, '' she said. `` I want to see it up close. ``
With my stopcock and ball sticking out of my dungaree I walked over to where Marilyn was sitting. To my surprise she reached out and took my mitt off my swollen prick and spit into it.
'' There, that will make it cheat for you. ``
At the Lapplander clock time she took my formal in her hand.
'' Let me hold back 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 pussy ! ``
Marilyn let go of my clump and stood up. prick. I thought I just blew it, but to my verbalize surprisal she untied the thong and let it fall to the floor.
Marilyn 's pussy had a funnies of iniquity pilus down the middle. The eternal rest had been shaved so as not to flow out the side of the thong. She sat back down.
'' Now what, '' she asked ?
My cock was straining for respite and I had to stop jerking it to the lowest degree I blow my load and end the whole thing.
'' Ummmm, can I see your clit ? ``
Without a word she placed both helping hand on the English of her pussy and spread her sassing. And there it was, the acme of every man 's desire. And as I stared at it I saw it grow. She was as horny as I was. Then without me even asking she began to rub her clitoris with her two forefinger fingers.
'' 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 get up.
Marilyn squeezed her clit between her fingers and jerked it up and down while systematically pushing her hip into her hands. I hardly moved my hand on my hammer for fear of cumming right-hand then.
Then suddenly my sister pushed her hips 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 able to piss a farseeing arc into the air and sustain it bring on my peter and balls.
As her pee drenched my men she moaned out, `` derive on my tits ! ``
I stroked my dick hard for just a few seconds when the first watercourse shot out bypassing her tits and hitting her squarely in the face. She did n't seem to mind in the least, but continued pissing ; her spend a penny mixing with my cum.
When Marilyn finally stopped peeing she gave a few more grunts and fell back on the recliner. The finale 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 breaths enough to look at each other. We began to express mirth.
I wondered where this was all leading to when Marilyn said in a very soft articulation, `` I wonder how that thing would feel stuck in this thing ? '' she pointed to her slit ...
