My Sister and I share the same natal day. We 're not twins though. We just happened to be born on the same day, but one year apart. I guess Dad was a officious guy back then.
Shortly after I turned sixteen and Marilyn turned 15 I began to notice that my footling baby was n't so picayune anymore. At fifteen years old she had already developed a rather expectant tit and a very overnice, voluptuous body. She was around five base eight or nine and I guessed her to be somewhere near one hundred twenty dollar bill Ezra Loomis Pound. She kept her hair short and parted on the incline. She did n't wear a lot of makeup, but then again, she was only fifteen and mom and dad did n't approve of that sorting of affair. She had definitely grown into a nice looking young fair sex. For me, we 'd gone from being just blood brother and sis to her becoming the fantasy of my recently night jerk off sessions.
As much as I fantasized about her coming to my room for raw sex adventure I knew this was something that was limited to the realm of my highly-sexed imagination. Still, I enjoyed it even if only in my mind.
The first time `` it '' happened was purely by accident. Mom and Dad had gone out to a dinner party party and Marilyn was over at her friends theater, or so I thought. I was in my way, on my bed with my figurer proctor facing me, watching a really good smut clip. I had taken all of my dress off so as to really savour my time alone. I had poured some oil over my Harlan F. Stone hard cock and was slowly rubbing it up and down. Obviously, I was lost in the porn military action because I did n't hear Marilyn number home.
The way my room is set up the mirror on my dressing table gives a complete mirror image of my bedroom door.
So, here I was stroking my shaft in complete defection when I noticed a movement behind me. Marilyn was standing there.
My initial reaction was to draw the bedspread over myself, but something stopped me. Maybe it was shock or superfluity or maybe something else, but instead of panicking I continued to rub my prick while my babe simply stood there watching.
The fervor of Marilyn watching me jerk off was a bend on I had never thought about before. In all my fantasies I had never given a moments thought to her watching me.
Before I realized how far along I was I shot a vast stream of cum into the air. It landed on my breast and breadbasket. A second and third current hit me in the look and pectus. I had never cum so intemperate in my life.
As the last remnants of my orgasm dribbled into my deal I looked up to see that my sister was gone. She must have sneaked out because a few minutes later I heard the front door open loudly and Marilyn came in the home a second time.
I went into the privy and took a quick shower, dressed and went downstairs to see what was going to happen.
My sister was sitting on the lounge watching something on TV.
'' Thought you were over at your friends house, '' I said, not looking directly at her.
She continued to gaze at the TV. `` I was, but her mom came rest home and started in about her not cleaning her room so I left. What are you up to ? ``
So, we were n't going to recognize what had just happened. `` I was just hanging around watching some Youtube vids. ``
And that was the end of it until a workweek later.
Our folks had gone out again, but this time Marilyn stayed dwelling house. I had a plan to see just how far this was going to go. After all, I had thought of nix else all week.
My sister and I were watching TV when I said, `` I 'm going up to my room to watch out some clip ''.
She merely shrugged as if to say, so what. We 'd soon see if her shrug was for real.
I found a soundly recollective video cartridge holder to look out and as before I stripped down naked and laid on my bed. I was so mad I was afraid I 'd spoil my consignment before Marilyn had a chance to follow me upstairs. I did n't have to worry though because as soon as I oiled my cock and began to flick it she was in the doorway. This fourth dimension I said, `` Come on in. ``
At get-go it looked like she was going to run off. I thought for certain she knew I had seen her the terminal time, but I guess I was wrong. After a short hesitation she walked slowly into my elbow room.
I had to focus all of my attention on not cumming right then and there.
Marilyn stood directly over me.
'' You 're discussing, '' she said never taking her eyes off my dick.
I continued to jerk off without answering her.
'' Is it going to shoot soon ? '' she asked, her vocalism a little ragged.
'' Yeah, pretty soon, '' I managed to say.
'' Does it finger good ? ``
'' Yeah, it feels material good. ``
'' Does it make you horny doing it in front line of me ? ``
I knodded.
Finally she admitted to seeing me cum the hebdomad before by saying,
'' Is it going to be as a lot as net time ? ``
Before I could answer I started cumming. I shot a huge stream into the air that went over my forefront and hit the headboard of my bed. A second shot went straight up and landed on my breadbasket. Several more hit me in the chest of drawers and legs. When I eventually stopped shooting I was drenched in my own cum.
Without a Word of God Marilyn walked out of the room, but returned a few moments later with a washrag. `` We 'd better get you cleaned up before Mom and Dad get home, '' she said and began wiping the cum off me. It took several trip to the bathroom for her to get me cleaned and I was thankful because I had cum so hard I did n't cause the energy to clean myself.
When she was done, she said in a angelic voice, `` secern me future prison term so I can watch from the beginning. ''
For the adjacent three calendar week we never got the star sign to ourselves. But I think this actually gave Marilyn time to get into it fully. It started with short innuendo, eye physical contact and debate brushing against me.
Finally after an infinity Mom and Dad went out one Friday evening.
I was in my room laying on my bed fully dressed when my sister came in.
'' What 's going on ? '' she asked, while avoiding looking at me.
'' Not much. How about you ? '' I pretended to read a book.
'' Lapp here, '' she said.
We got calm for a while then Marilyn spoke. `` So, you gon na do it tonight ? ``
I put the book down. `` I do n't live. I thought maybe you 'd do it for me ... ''
'' What do you signify ? You want me to jerk you off ? ``
'' Sure, why not '' ?
She shook her question. `` No way, Jose ! leave it. ``
'' OK, see ya later '', I said and went back to my book.
Marilyn looked surprised. `` I thought you said you were gon na do it ? ``
I put the book down for the arcsecond sentence. `` Oh, I am. But you 're not going to be there. ``
'' Fine, '' she said and stormed out of the room.
crap. Maybe I pushed it too far. I waited for a few minutes and was just about to call her back when she walked into my room.
'' I 've never done anything like this before, '' she said, as if I had thought otherwise.
I tried to act matter-of-factly, but my hired hand were shaking. When I slid my pants and underwear off and sat on my bed my dick sprung out. The head was red and swollen, the tool equally so.
Marilyn gasped. I could't charge her. It looked intemperate and mean.
'' What should I do, '' she asked ?
'' Well, you can pour some of this on it, '' I said handing her a bottle of oil.
Marilyn did as she was told.
'' Now put your hand around it like the grip on a handlebar and go up and down. ``
For a moment she paused, then took my cock in her velvet hand and began to stroke it up and down.
This was the first time a paw, early than my own, had been on my cock and it felt unbelievable.
As Marilyn stroked me up and down I arched my hips in clip to her drive. Her oiled hired hand felt like what I imagined a pussy would feel like and I fucked it as toilsome as I could.
Precum began to ooze from the tip of my engorged cock. Marilyn took my clump in one paw and continued to jerk me off with the former. I was n't going to last lots longer and I told her so. She laughed.
'' Do you desire me to discontinue, '' she said dropping my cock and testis ?
'' Oh hell no, '' I whimpered.
She took my cock back into her manus and started jerking it again.
'' I want to see it shoot a lot, '' she said.
To my surprisal my baby let her proper hired hand yank me as it had, but ran the palm tree of her left hand over the swollen dick head.
This was it. Before I could say anything a vast stream of cum shot out against her hand spraying us both with equalise amount. I moaned and Marilyn laughed.
With her left manus covered in cum she placed it back on my cock along with her right manus and resumed jerking me off with both.
I pushed into her bridge player as if my life history depended on it. She, in go, squeezed her hands tightly around my cock as hot cum flew everywhere.
I must have shot ten streams before I finally finished and collapsed onto the bed .
