Marilyn stroking my cock was the beneficial matter I ever felt. I could n't wait for the next time we had the house to ourselves.
Well, I did n't have to expect very long. Two mean solar day later our parents announced that they were going to a clientele meeting Dad had on the Occident coast and that Marilyn and I would be staying home plate. Oh darn ...
I had just gotten my driver 's licence so it was my job to take up Mom and Dad to the airport.
'' Take tutelage of your babe, '' Dad said, `` and no political party ! ``
A slight voice in my headspring said, `` No problem ! ``
When I got home Marilyn was out laying in a chaise by the pool. She was wearing a G-string Bikini that covered her private division, but just barely. The top was two little dapple of material that hid only her nipples. The bottom was even smaller.
'' Where did you get that, '' I asked ? I could n't conduct 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 reply 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 matter of factly.
Marilyn shrugged. `` I do n't know. I thought about going to the shopping center with Becky or maybe a pic with sallying forth. ``
My nerve sank. I was really hoping for another handjob.
She pushed her glasses back up and layed her question back on the chaise.
'' Or maybe I 'll just abide here and watch you jack your stopcock. ``
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 hammer twitched in my pants.
'' fountainhead, 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 nipple were everything I had imagined and more. They were perfectly symmetric and her nipples were just as arrant pointing heterosexual 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 cock in my hired man and began stroking while I stared at Marilyn 's double-dyed tit. She, in act, stared at my cock which was already oozing a clear viscid liquid.
'' Come finisher, '' she said. `` I want to see it up close. ``
With my cock and balls sticking out of my jeans I walked over to where Marilyn was sitting. To my surprise she reached out and took my hired hand off my swollen asshole and spittle into it.
'' There, that will make it slicker for you. ``
At the same sentence she took my balls in her hand.
'' Let me check these out of the way, '' she said with a grin.
As much as my sister was trying to venture 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 slit ! ``
Marilyn let go of my balls and stood up. poop. I thought I just blew it, but to my staring surprise she untied the thong and let it decrease to the floor.
Marilyn 's pussy had a strip of sorry 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 cock was straining for relief and I had to stop jerking it to the lowest degree I blow my loading and end the whole affair.
'' Ummmm, can I see your button ? ``
Without a give-and-take she placed both hands on the sides of her puss and spread her sass. 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 clit with her two forefinger fingers.
'' 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 catch up with up.
Marilyn squeezed her clit between her fingers and jerked it up and down while systematically pushing her pelvic girdle into her workforce. I hardly moved my script on my stopcock for fearfulness of cumming right on then.
Then suddenly my baby pushed her pelvic arch 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 receive it set down on my cock and balls.
As her pee drenched my hands she moaned out, `` come in on my tits ! ``
I stroked my peter hard for just a few arcsecond when the showtime stream shot out bypassing her breast and hitting her squarely in the face. She did n't look 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 last of my cum was dribbling out of my tool as I collapsed in the chair side by side to her.
After a few minutes we caught our breaths enough to wait at each other. We began to laugh.
I wondered where this was all leading to when Marilyn said in a very indulgent voice, `` I wonder how that thing would finger stuck in this matter ? '' she pointed to her snatch ...
