I have to write about this because every detail is burned into my brain, was so hot and I still can't believe it happened.

Every year in autumn, my wife and I go on an extended weekend horse riding camp with our daughter who is now 13.

There are a few families who come every year and some who are new. This year there was a new family who are experienced riders Stuart, Caroline and their daughter Annabel (Annie). Caroline and Annie are the riders, Stuart was only there for a relaxing weekend and didn't ride. Annie is in her final year at high school so is 18 years old and could sit at the adults table and allowed to drink alcohol.

Annie is very beautiful, has a great figure, well, as much as you could see through the layers of clothes in the cold autumn, but she certainly filled out her jeans nicely. The women, including my wife, at various times commented on how beautiful she is.

As an older parent, in my early 60's, I was very careful not to ogle or come across as sleazy, but was taking as many photos of Annie as I could with my iPhone, everyone was always taking photos of everything all the time so it wasn't too hard. We did talk a few times about riding as it was her whole life, she was always up early helping with the horses and giving tips and help to the novice riders.

On the last night, a clear cold cloudless night, we had a huge bonfire after dinner, the kids were running around throwing sticks on and playing games and the Adults standing around drinking and talking.

At one point I needed to pee and with the bonfire casting a lot of light I walked some distance away behind a stand of trees to have a bush wee. When I finished I turned to head back and saw a figure in the dark about 10 feet away, I walked closer and saw in the starlight it was Annie.

She said "Hi, did you come over here for a wee too?"

I said "yes, did you?"

She said "yes, all done, but I'm quite cold now" and stepped really close "have you finished?"

"Yes thanks"

She stepped right up to me and slid her arms around my waist under my jacket pulling me  close and pressing her breasts against my chest.

"hmmm" She said "you're nice and warm" and rested her head on my shoulder. She was now pressing her whole body against me, she also was warm and smelled great, it was having an effect, I was glad I had both peed and put my penis away properly, as it was starting to grow.

She said "I saw you taking photos of me, do you think I'm pretty?"

Not sure where this was going, I decided to be as straight and honest as I could. "Yes, and you are, I hope you don't mind"

"No I don't mind, it kinda turns me on."

I thought "WHAT?"

My eyes had adjusted to the dark and I looked down to see her looking up at me, when she saw me look at her reached up and kissed me on the mouth.

We started to french kiss in earnest and she was rubbing my penis through my jeans with one hand, the other on my back pulling me close.

We stopped to catch our breath and she stepped back, unzipped her jacket, unbuttoned her shirt, took my hand and put it on her breast on her bra. I took the hint and slid my hand around her back under her shirt and unhooked her bra. Her breasts were firm and soft and wonderful with hard rubbery nipples.

She said "Oohh cold hands" and stepped close and we started kissing again.

No longer able to caress her breasts I reached down and with one hand undid her belt buckle, then the button on top of her jeans, then the zipper and slid my hand down inside her silky panties, finding her bushy pubic hair, continued down to her pussy sliding into her very wet, very hot slit.

Stooping slightly and still fervently french kissing her I started dipping my finger into her vaginal opening as far as I could, bringing the hot wetness up and circling her clitoris and back down again. She groaned into my mouth so I started using two fingers stooping further to get a better reach, she started to buck her hips against my hand, this allowed me to go deeper with my fingers with each stroke and press the palm of my hand against her pubic mound and clit.

At this point we're standing at an angle to each other, still kissing, one arm around each other, my hand down her jeans and her free hand rubbing my very hard cock through my jeans.

She got more fervent with her hips, breaking off the kiss, breathing heavy and started whispering

"Yes"

"Fuck"

"Oh God"

"Yes"

Bucking her hips harder she suddenly put both arms around me, turned and jammed my hand between us, hard up against my cock, squeezed her legs together and groaned as she came on my hand.

Fuck it was sexy

...and I had a huge boner.

After a moment when her breathing had returned to normal, she kissed me again, pulled my hand out of her pants and sucked the juices off my fingers and said

"Your turn"

She pulled her jeans up and did them up along with her belt, left her shirt and bra undone, pushed me against a tree so I had my back to the distant bonfire with the tree in between, squatted down, undid my belt and jeans, pulled them down, but left my boxers up, reached in through the fly and took out my hard cock and balls, holding my balls in one warm hand guided the cock into her mouth with the other and started to blow me. She was very good. almost gagging as she took me in as deep as possible. It was so hot, so sexy and so unbelievable that this totally gorgeous 18 year old girl was blowing me that I came without warning and filled her mouth with my cum... and then she swallowed it!

She stood up and giggled a bit and kissed me again, I could taste my own cum on her tongue and took advantage of her open top to caress both her breasts at the same time. She broke off the kiss pulled back and put her boobs back in the bra, reached behind and did it up, then buttoned her shirt, undid her belt and zip so she could tuck in the shirt, did the jeans up and zipped up her jacket.

Mesmerized I suddenly realized I was standing with my jeans at my ankles and my cock and balls in the cold air, my cock was still half hard. I put my equipment away, leaned down and pulled up my jeans, did them up, tucked in my shirt and zipped up my jacket and looked and she was gone.

I walked out from behind the stand of trees and made a bee line for the cooler with the beer, grabbed a beer and joined the group of adults talking with my wife. She said

"where have you been?"

"I needed to pee."

"Still having trouble with your prostate?"

"Yeah, it can take a while."

I noticed Annie talking to some other adults in another group with her parents. She never even looked in my direction for the rest of the evening.

The next morning the camp was over and we all went our separate ways.

I wonder if she'll be there next year.
