My sister is 6 years younger than me. We never spent a lot of time together. We each had different friends and boyfriends. Hers were too young for me and mine were to old for her. That was until I married a man 3 years younger than myself and 3 years older than her. It all started like this. We were both going to school and when I saw him I told my horny little sister to leave him alone he was mine. I think she took it as a challenge but I won. After we were married we went to another college town to finish school and she went home to work for a while.
We were going to school trying to get our degrees while living in an old run down house. One day I got a call from my sister Kate who said that she had a guy stalking her. After talking a while I found out that my sister had a love and weakness for the feel of a hard-on agents her body especially her ass. This didn't surprise me because I did too. And she being who she was liked to grind boys to there limit and watch there face as they cummed. Here is the funny thing as horny as she was, she only wanted to fuck the guy she was going to marry and not be "a horny slut" as she put it..
So one night after jogging with her boyfriend they started to get hot and heavy. She started lap dancing on his hard-on and soon was lost in the kissing, fondling of her breast, and the feel of the hard-on pressing agents her slit when all of a sudden he spun her onto the couch and had his bare dick in her face. This was the first one she had ever seen up close and hard and as she reached up to move it away form her mouth she said she had never felt something so soft and hard all at once. She said she could feel it throbbing in her hands and as she got a better look could not make herself let go. Soon she was rubbing it on her face and then light little kisses and then long kissed followed by licks until she was giving her first blow job. While she was sucking, his hand was working its way into her shorts. With a cock throbbing in her mouth and her hard clit being caresses she was lost in the moment.. She said that while she realized somewhere in the back of her mind that her sweats had come off and her legs were spread she did not expect what happen next., being a air head.
He pulled out of her mouth and then thrust it in her pussy and as he did she was lost in the feeling and let herself be fucked for the first time. The total mix of good and bad. After he cummed he left her there legs spread unsatisfied. Alone she started to feel and play with herself and explore her now gapping hole and taste their juices and then took herself over the edge again and again. I guess that she had played with herself but never actually brought herself all the way before. The next morning feeling guilty that she had gone all the way with a guy she really didn't want to marry she stopped seeing him and he got weird and she came to live with us.
Big Teaser Gets Embarrassed
When she got there I could tell she was a bit of an exhibitionist but then so was I. She used to wear big over sized tee shirts to bed and would get into them in the early evening. When she got there it was winter so under the tee she would wear her sweat bottoms. She would take ever chance to bend over in front of him and show of her tits. The shirts were so big it left nothing to the imagination. When we would play dice she would always sit across from him and every time she reached for the dice she would give him a show. Sometime she would sit there doggy style rolling dice, jiggling her tits with hard nipples and look up and smile at him.
I guess that in her way she had fallen for him.
One evening I borrowed a big shirt from Kate and we gave a 5 dice 4 nipple 2 sweat bottom show. I finally in teasing said to him if you would stop starring at our tits you might win once! Now he is very competitive. In this particular game he was never good at, so he retaliated back with something a little cutting and I looked over at my sister and told her to hold him down he needed tickling. Now he is very ticklish and so we over powered him easily.
I took off his shirt and warped it around his head and on went the wrestling and the tickling until he grabbed my sister from under her shirt. He grabbed her tits and said "tell your sister to stop tickling or else". He thought he had my tits in his hands . I thought if you only caressed them a little you would know you made a mistake. I said nothing and he began to roll her nipples like I love and by the look on Kate's face she was going to do nothing to stop it. "Or else what" I said, careful that my voice was coming from the right direction. At this point he slipped his hand down the front of her sweats and whispered in her ear no panties.
The look on her face was ecstasy and terror all in one. but she couldn't help it her legs spread and he ground his hard on against her ass. I quietly walked behind him and tickled for all I was worth. All of a sudden I looked up to the sound of a hand slapping skin. He had dropped to his knees and taken her sweat bottoms with him. He had pulled her sweats around her ankles and in a last attempt to retaliate for the endless tickling was waking her ass. I pulled the shirt off of his head. This left his face inches from her ass with cherry red hand prints on it.
All of a sudden he burst out "KATE I AM SORRY I THOUGHT YOU WERE." ... she spun around as his eyes became glued to her crotch. If he hadn't been so genuinely surprised he would of noticed that her legs were spread her hole glistening and her clit hard but the moment was so awkward that they both stood up to face each other. Her wet crotch was soon covered back by those sweats but her nipples pushing through the fabric of her shirt told everything about how she felt, and his dick pushing hard agents his sweats told the rest.
They could only make eye contact. It was a bizarre feeling of power and sheer slutty horniness. I said kiss and make up. They gave each other a peck . I said with such a half hearted kiss at least give each other a big hug so I know you both still like each other. As he hugged her I saw his tented shorts push against her stomach and her hard nipples push against his chest. At that I took him by the hand to the bedroom.
Sister Gets the Show
Now you might think this kind of stuff would make me jealous but instead I liked it. After a good tease by my sister the sex was always great. This night was even better than great, by a little moon light sucked we fucked each others brains out and as we fucked we heard a familiar sound, my sister finger fucking herself into oblivion.
The sound was usually a muffled sound of sighing, maybe a slap or two, a creak of the bed but always soft. This time it was louder and more intense. This time I could even hear the sound of pussy lips moving under wet fingers and the unmistakable sound of a wet hole opening and closing. These sounds are so quiet yet so sensual it only added to our pleasure as we 69ed away. Then I mounted that magnificent cock and road myself into my third oblivion. As I finished I thought how in the hell were these sounds so clear from my sister. The things you think of after sex.
After a few minutes the bathroom door quietly opened and she walked down the hall. I looked over to the wall separating the bedroom from the bathroom and saw the air vent. By the moon light I could make out the shadows of the bathroom sink. SHE HAD BEEN WATCHING. I went to whisper this into Rand's ear but he was asleep. As I sat there the feeling of having been watched as I sucked and fucked Rand was hot. It made me horny and I began to plot to have it happen again as I imagined over and over the scenes of that night.
The Sex Plot
As summer came, the sweat bottoms came off of Kate and I watched as her teasing became more intense, a flash of ass, a quick peak of pussy, a brush agents his cock. This made him fuck happy but I didn't mind because the thought of her watching made my pussy hungry for attention. And it got it. But for all the fucking as loud and long as we did it I never saw her shadow in the bathroom again. I needed it and I had an idea.
I went to the adult store. Boy talking about eyes. All guys all horny all looking at me. I bought a double ended gel dildo and a fuck magazine and took it home. I unwrapped the gel dildo and found myself kind of hot and horny I started to play with it and soon I was sliding it between my lips across my sensitive clit. Then it was in me and for the first time I understood my sisters new found love of masturbation. I began to flip through the pages and soon was lost in the fantasy of her watching like I was looking. I began to orgasmed hard as I turned the page and saw a threesome in action.
I cleaned the dildo up and went to the computer and typed this note.
"I love watching your tits when you bend over, your ass when you reach up, your pussy in the morning as you sit cross legged in the chair for breakfast, your wet hole, when I get a peek. I love the sound of your wet fingers dancing in you, it make me want to worship you. I'll leave the door open while we fuck, just know tonight I wish it were your pussy. Please come and watch"
I printed the note on one of the pictures I tore out of the magazine. It was a close up of a girl sucking a cock . I thought about signing it but I couldn't copy his signature so I attached this note to the dildo and slipped it on Kate's pillow.
