Wrestling And Horse Racing With Sister

I grew up with a sister who was only about a year and a half younger than me.

In our house hitting or hurting girls wasn't allowed which was something my sister took advantage of regularly.

If she was bored, and I was by myself, doing something quietly such as reading a book she would snatch the book away from me and run off with it. I, of course, would run after her to try and get my book back. Although catching her was easy, getting the book back was more difficult as I wasn't allowed to hurt her. This would result in a wrestling match where, after a struggle, I might finally get the book back, but with my place in the book lost.

There came a time when she grew a lovely pair of little titties and I started to notice them. It didn't take her long to realise the new found power that having breasts gave her.

It was a warm summer and every time our parents were out of the house she'd change into shorts with a loose T-shirt and no bra, or a bikini. The bikini top was a little too large for her little titties.

If she caught me looking at her titties then she'd give them a wiggle which would show her nipples through the T-shirt, and that would give me a hard-on which made an obvious bulge in my clothing.

Sometimes she would get a little bolder and lift up her T-shirt giving me a quick flash of her little titties.

One day she appeared in her T-shirt and shorts while I was reading a book. I looked up and she pulled the T-shirt tight across her titties so her nipples stood out. My cock grew instantly hard at this sight.

Then, while my attention was diverted, she snatched the book from me and ran off. I managed to catch her and got one hand around her wrist where she had the book in her hand. I tried to grab the book with my other hand, and she clamped her free hand around my wrist to stop me grabbing the book.

As we wrestled she was moving my arm which she was holding by the wrist. Suddenly she moved it so my hand was on her breast and held it there for a second. Then she pushed my hand away and said, "Naughty naughty." Having not felt a girl's breast before it made my already erect cock rock hard. After a little bit more wrestling my hand was propelled towards her breast again, and this time she kept it there a little longer. She looked at the bulge in my trousers, said, "Naughty naughty," and pushed my hand away again.

A long time ago she'd worked out that if she looped one of her legs behind mine, and gave me a shove, I'd go down. This time I landed flat on my back with her on top of me. She grabbed both my wrists to hold me down, and sat astride me. She moved so that she was sitting on my hard cock and leaned forward. When she leaned forward I could see down her T-shirt which enabled me to see her bare titties. She looked down her T-shirt to make sure they were in view and gave them a little wiggle then looked back at me and said, "You're my horse and we're in a race." With that she started making horse riding movements rubbing herself against my hard-on.

As she rocked backwards and forwards on my cock she started giving me a horse racing commentary. Every time she overtook another horse she'd rock backwards and forwards faster. Every time we went over a jump she'd rub herself round and round on my cock as well as backwards and forwards. While she was doing this I was looking down her T-shirt watching her little titties moving around now with the nipples really sticking out.

By this time I was getting quite close to cumming from all the visual and physical stimulation I was getting, and my sister seemed to be getting a bit out of breath as she was breathing heavily.

Then she started gripping my wrists tightly, and I felt her legs tense up. She was riding me quite fast now, and she said, "I'm going to win," and was pressing herself hard against my cock as she rode me. "Yes, I'm going to win," she said. Her movements got suddenly jerky and she said, "Oh yes, I'm winning, I'm winning," and as she said that I started to cum in my underwear. She collapsed jerkily on top of me for a moment or two. Then when she'd recovered got off me, threw my book at me and went away. I had to go to my room to clean up the mess in my underwear.

Over the next two or three weeks it happened a couple of times more, and I wondered if she could feel my cock's muscle movements when I orgasmed. I soon had my question answered as after another race she asked, "Did you win too?" to which I answered, "yes," and she said, "it feels good doesn't it?"

After that she didn't bother with the wrestling, she'd make sure I knew she hadn't got a bra on by leaning over me so I could see down her T-shirt. When the bulge appeared in my trousers she'd say, "Let's play horse racing," and tell me to lay down.

One hot day I was in the garden wearing just my swimming trunks, and she came out wearing her bikini. She leaned forward over me and I could see her titties down her loose bikini top. She looked down it herself to make sure I could see them and then smiled at me. A big bulge appeared in my swimming trunks which she looked at and said, "Did I do that?" My cock just reached the elastic of the waist band and lifted the elastic away from my body. "I think you want to play horse racing again," she said and pulled me into the house then pushed me on to the floor. She straddled me with her bikini bottoms in contact with my trunks. Her pussy was on my hard cock with only two thin strips of material between them. She started rubbing her pussy up and down my cock without the horse racing commentary this time. She kept moving around a little, obviously trying to get the best place of contact. As she rode me her little titties were popping in and out of view with the motion of her slightly loose bikini top. Then they popped right out and she left them there for me to see. I was getting close to cumming again seeing her bare titties with her nipples sticking out, and her pussy rubbing against my cock. She grabbed my hand and put it on one of her exposed breasts and squeezed it. "Do it like that," she said as she squeezed my hand onto her breast. By now she was breathing heavily and I could feel her legs tensing around my body. I squeezed her little titty gently, feeling the hard nipple against my hand. "Oh," she said, "I think I'm going to win," as she sped up the movement of her pussy against my very hard cock. "Yes I'm going to win!" she said as she rubbed her pussy round and round and up and down on my cock. She suddenly went stiff and said, "Oh I'm winning, I'm winning," and her body started jerking a little. That made me cum, and as my cock was almost sticking out of the top of my swimming trunks my cum spurted out over my stomach. She kept wriggling on my cock for a short while then she looked down at the sticky mess on my stomach and said, "Is that what happens when you win?" and put her finger tip into it and kept sliding it around until I got a tissue to mop it up.

We had a few more horse races that summer, but when the weather got colder it stopped, and never happened again.
