Marilyn stroking my cock was the best thing I ever felt. I could n't wait for the side by side time we had the theater to ourselves.
Well, I did n't have to await very long. Two days later our parents announced that they were going to a business merging Dad had on the west coast and that Marilyn and I would be staying home. Oh tinker's dam ...
I had just gotten my number one wood 's license so it was my job to take Mom and Dad to the airport.
'' Take care of your sister, '' Dad said, `` and no company ! ``
A piddling voice in my forefront said, `` No trouble ! ``
When I got home Marilyn was out egg laying in a chaise by the kitty. She was wearing a G-string bikini that covered her common soldier parts, but just barely. The top was two little piece of fabric that hid only her mammilla. The bottom was even smaller.
'' Where did you get that, '' I asked ? I could n't consider my centre off of her.
She pulled her sunglasses down just far enough to look 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 respond she looked at my crotch 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 issue of factly.
Marilyn shrugged. `` I do n't know. I thought about going to the shopping mall with Becky or maybe a movie with Sally. ``
My heart 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 stay here and catch you jack your hammer. ``
Yes !
'' That sounds like fun, '' I said then added, `` It would be even better if I could see your tits while I did it. ``
'' Hmmm, you think so, '' she said through a smile.
My cock twitched in my trouser.
'' well, take it out and let 's see what happens, '' she said.
'' Out here, by the puddle ? ``
Marilyn looked around. `` Why not ? It 's just you and me out here. '' With that she reached can and untied the Bikini top letting it strike away.
Her breast were everything I had imagined and more. They were perfectly proportionate and her nipples were just as gross pointing straight ahead. From the feeling of it I thought she was enjoying this a little more than she was letting on.
'' okeh, start jerking it. ``
I took my cock in my hand and began stroking while I stared at Marilyn 's perfect bosom. She, in bit, stared at my cock which was already oozing a clear sticky liquid.
'' seminal fluid closer, '' she said. `` I want to see it up close. ``
With my putz and bollock sticking out of my jeans I walked over to where Marilyn was sitting. To my surprisal she reached out and took my hand off my swollen peter and spitting into it.
'' There, that will build it tricky for you. ``
At the same fourth dimension she took my balls in her script.
'' Let me view as these out of the way, '' she said with a smiling.
As much as my sister was trying to pretend this was a big joke 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 pussy ! ``
Marilyn let go of my globe and stood up. Shit. I thought I just blew it, but to my utter surprisal she untied the thong and let it fall to the floor.
Marilyn 's pussycat had a strip of sinister hair's-breadth down the middle. The respite had been shaved so as not to hang out the side of the thong. She sat back down.
'' Now what, '' she asked ?
My cock was straining for relief and I had to bar jerking it least I blow my warhead and end the whole thing.
'' Ummmm, can I see your clit ? ``
Without a countersign she placed both manus on the side 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 grow. She was as horny as I was. Then without me even asking she began to rub her button with her two index fingerbreadth.
'' I 'm warning you, '' she said, `` sometimes I pee when I come. ``
I could hardly stand it, but I held off cumming to let her trance up.
Marilyn squeezed her clit between her digit and jerked it up and down while systematically pushing her hip into her hands. I hardly moved my hands on my cock for fear of cumming rightfulness then.
Then suddenly my sister pushed her rose hip 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-bodied to piss a farsighted arc into the air and consume it set ashore on my peter and orb.
As her pee drenched my hands she moaned out, `` Come on my titty ! ``
I stroked my putz hard for just a few endorsement when the first stream shot out bypassing her mammilla and hitting her squarely in the fount. She did n't look to mind in the least, but continued peeing ; her piss mixing with my cum.
When Marilyn finally stopped peeing she gave a few Thomas More oink and fell back on the recliner. The endure of my cum was dribbling out of my cock as I collapsed in the death chair next to her.
After a few transactions we caught our hint 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 voice, `` I wonder how that thing would feel stuck in this affair ? '' she pointed to her snatch ...
