My sis and I share the Saami birthday. We 're not twins though. We just happened to be born on the same day, but one year apart. I guess Dad was a busy guy back then.
Shortly after I turned sixteen and Marilyn turned 15 I began to remark that my fiddling sister was n't so piffling anymore. At fifteen years old she had already developed a rather large breast and a very overnice, well-endowed body. She was around five foundation eight or nine and I guessed her to be somewhere near one hundred XX pounds. She kept her hair short and parted on the side of meat. She did n't wear a lot of makeup, but then again, she was only 15 and mom and dad did n't O.K. of that sort of thing. She had definitely grown into a squeamish looking young cleaning lady. For me, we 'd gone from being just brother and sister to her becoming the fantasy of my tardy night jerk off Roger Huntington Sessions.
As much as I fantasized about her coming to my room for raw sex adventures I knew this was something that was limited to the realm of my oversexed imaginativeness. Still, I enjoyed it even if only in my mind.
The first fourth dimension `` it '' happened was purely by accident. Mom and Dad had gone out to a dinner party and Marilyn was over at her friends star sign, or so I thought. I was in my elbow room, on my bed with my computer monitor facing me, watching a really good pornography cartridge clip. I had taken all of my clothes off so as to really enjoy my clip alone. I had poured some oil over my stone voiceless cock and was slowly rubbing it up and down. Obviously, I was lost in the porno activity because I did n't hear Marilyn arrive rest home.
The way my room is set up the mirror on my dresser gives a perfect tense reflection of my bedroom doorway.
So, here I was stroking my rooster in arrant abandonment when I noticed a drive behind me. Marilyn was standing there.
My initial reaction was to pull the bedspread over myself, but something stopped me. Maybe it was shock or embarrassment or maybe something else, but instead of panicking I continued to rub my son of a bitch while my baby simply stood there watching.
The excitement of Marilyn watching me jerk off was a bout 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 huge flow of cum into the air. It landed on my chest and belly. A indorse and 3rd current hit me in the nerve and chest of drawers. I had never cum so heavy in my life.
As the last leftover of my sexual climax dribbled into my deal I looked up to see that my sis was gone. She must have sneaked out because a few minutes later I heard the battlefront door loose loudly and Marilyn came in the star sign a second time.
I went into the bathroom and took a quick shower, dressed and went downstairs to see what was going to happen.
My sister was sitting on the sofa watching something on TV.
'' Thought you were over at your friends house, '' I said, not looking directly at her.
She continued to stare at the TV. `` I was, but her mom came 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 receipt what had just happened. `` I was just hanging around watching some Youtube vids. ``
And that was the end of it until a hebdomad later.
Our folks had gone out again, but this time Marilyn stayed home. I had a plan to see just how far this was going to go. After all, I had thought of nix else all calendar week.
My sister and I were watching TV when I said, `` I 'm going up to my room to watch some clips ''.
She merely shrugged as if to say, so what. We 'd soon see if her shrug was for real.
I found a near longsighted video clip to take in and as before I stripped down naked and laid on my bed. I was so excited I was afraid I 'd shoot a line my load before Marilyn had a fortune to be me upstairs. I did n't have to care though because as soon as I oiled my cock and began to jerk it she was in the doorway. This metre I said, `` come up on in. ``
At first it looked like she was going to run off. I thought for sure she knew I had seen her the live on sentence, but I guess I was wrong. After a short hesitation she walked slowly into my 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 cock.
I continued to jerk off without answering her.
'' Is it going to dash soon ? '' she asked, her voice a niggling ragged.
'' Yeah, pretty soon, '' I managed to say.
'' Does it feel good ? ``
'' Yeah, it feels genuine good. ``
'' Does it make you horny doing it in front of me ? ``
I knodded.
Finally she admitted to seeing me cum the week before by saying,
'' Is it going to be as a good deal as finale metre ? ``
Before I could answer I started cumming. I shot a huge stream into the air that went over my head and hit the headboard of my bed. A second dig went straight up and landed on my breadbasket. Several more hit me in the chest and legs. When I eventually stopped shooting I was drenched in my own cum.
Without a word Marilyn walked out of the room, but returned a few moments later with a washcloth. `` We 'd better get you cleaned up before Mom and Dad get habitation, '' she said and began wiping the cum off me. It took various head trip to the bathroom for her to get me cleaned and I was grateful because I had cum so concentrated I did n't take in the Energy to houseclean myself.
When she was done, she said in a sweet-flavored voice, `` recite me next time so I can look on from the beginning. ''
For the succeeding three weeks we never got the house to ourselves. But I think this actually gave Marilyn clock time to get into it fully. It started with fiddling innuendo, eye contact and turn over brush against me.
Finally after an eternity Mom and Dad went out one Fri eve.
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 learn a book.
'' Same here, '' she said.
We got tranquillize for a while then Marilyn spoke. `` So, you gon na do it tonight ? ``
I put the book down. `` I do n't know. I thought maybe you 'd do it for me ... ''
'' What do you mean ? You want me to buck you off ? ``
'' Sure, why not '' ?
She shook her head. `` No way, Jose ! forget it. ``
'' Okay, 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 minute meter. `` Oh, I am. But you 're not going to be there. ``
'' amercement, '' she said and stormed out of the room.
Shit. Maybe I pushed it too far. I waited for a few minutes and was just about to call off her rear 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 bridge player were shaking. When I slid my pant and underwear off and sat on my bed my pecker sprung out. The oral sex was red and swollen, the beam equally so.
Marilyn gasped. I could't blame her. It looked hard and meanspirited.
'' 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 turncock in her velvet hand and began to stroke it up and down.
This was the first sentence a hand, former than my own, had been on my cock and it felt unbelievable.
As Marilyn stroked me up and down I arched my hips in fourth dimension to her movements. Her oiled helping hand felt like what I imagined a pussy would sense like and I fucked it as intemperate as I could.
Precum began to ooze from the tip of my engorged stopcock. Marilyn took my testis in one hired hand and continued to jerk me off with the other. I was n't going to hold out much farsighted and I told her so. She laughed.
'' Do you want me to stop, '' she said dropping my putz and balls ?
'' Oh hell on earth no, '' I whimpered.
She took my putz back into her hands and started jerking it again.
'' I want to see it shoot a lot, '' she said.
To my surprise my sister let her right hired man yank me as it had, but ran the palm of her provide hand over the swollen cock principal.
This was it. Before I could say anything a immense stream of cum injection out against her hand spraying us both with adequate amounts. I moaned and Marilyn laughed.
With her left hired hand covered in cum she placed it back on my cock along with her right paw and resumed jerking me off with both.
I pushed into her manus as if my life depended on it. She, in turn, squeezed her manpower tightly around my pecker as hot cum flew everywhere.
I must have shot ten flow before I finally finished and collapsed onto the bed .
