Alice wanted to go hiking again the next day, but this time she wanted to be totally naked, no hiking boots. Knowing that that would slow us down I suggested a shorter hike, a loop that would take us to the edge of the hills. I reminded her that that trail took us by a waterfall to a stream that fed into the lake.

With Alice totally naked and me carrying the backpack with a towel, some food and other essentials we set out, waving to the 4 guys and Ted and Mary as we left. It was slow going with no chance of breaking sweat but Alice said that being 100 percent natural was a great feeling, like swimming naked.

Yes we did meet a few other people out walking and we did talk to some of them. One woman told us that she wished that she had Alice’s courage and her husband agreed.

When we got to the waterfall Alice was straight in and I’d remembered to take my phone so I photographed and videoed her thinking that I hoped that I remembered to move those images to my laptop before showing mum or dad the photos of our visit to the cabin.

After a while I stripped and joined Alice and we had just started fucking in the water when another young couple appeared. When they saw us in the water they decided to come on in as well. At one point I think that both girls were getting fucked in the water at the same time.

Alice had been in the water the longest and when she started getting cold we got out. They didn’t say anything but the couple stared at as as I got dressed then with Alice still naked, we set off walking again.

That night was another one where we were both trying to wear-out our sex organs.


The next morning was our last full day at the cabin and Alice wanted to spent it at the beach. What’s more, she was going to be totally naked regardless of who might be there.

Before we went there Alice just had to have an outdoor shower for the 4 guys who were sat on their veranda. From a distance I watched her shower then make herself cum for them then wave as she returned to the cabin.

We actually had a quiet day on the beach soaking up the sun and swimming in the lake. Alice got me to fuck her when we were in the water but it was unlikely that anyone saw what we were doing.

That evening we were invited over to the boys cabin and Alice put on a show for them making herself cum using both her fingers and a beer bottle. She let them take some more photographs of her as well.


Our going home day and Alice wanted to make the most of the few hours that we had left there so she waited until the 4 guys were on their veranda then led me out to the front where the guys could see us then she started kissing me and letting her hands wander. As she unfastened the belt of my shorts I knew what was coming and so did my cock. It was pointless objecting so I just went along with it and we fucked right in front of the 4 guys. Whenever I looked at Alice I saw that she was watching the 4 guys watching her.

After another loud orgasm she got up then went to the outside shower where she got herself clean then rubbed her pussy until she had another loud orgasm.

By that time I had gone inside, had a quick shower and was loading up the car. When Alice joined me she put her shower things into the car then we went over to the 4 guys to say goodbye. Dan gave Alice his email and phone number asking her to contact him if we were going up to the cabin again.

Alice got into the car and we drove off, Alice not even asking if I’d kept a dress out for her for if we stopped. It was only when she got out of the car at the service area and stood there totally naked that she remembered and asked me to get something for her to wear.

Mum was at home when we got there and she wanted to know if we’d had a good time. I told her that I’d show her the photos later when I found out which bag I’d left my phone in.

Shortly after we got back from the cabin I got a phone call Dylan telling me that Alice and I were invited to a ‘starting our last year at school’ party at another girl’s house, Annie’s, who we both knew but not really well. Dylan also told us that Annie’s parents wouldn’t be there. Alice immediately decided that somehow she wanted to get naked at that party and she asked me if I could think of a way that we could make it happen.

Alice suggested ‘truth or dare’ but somehow that didn’t seem to work for either of us. Maybe we didn’t have enough imagination. We thought and thought and eventually I hit on an idea and Alice thought that it could work. It was one that didn’t require much planning, only me downloading an app onto my phone and getting familiar with it. The only other thing was to sketch out a rough plan of what we (Alice) wanted to happen.

That done we got on with enjoying ourselves whenever mum and dad weren’t around.

We also went online and researched dogging, and in particular in our area of the country. We were both amazed by how many sites there were and couldn’t wait for mum to be away one night and for her to leave her car at home.

We didn’t have to wait long and we set off that evening with Alice bubbling over with excitement. We’d planned it so that we got there just after dark arrived and saw that it was a car park at the side of a small lake. It was set back from the main road so passing traffic wouldn’t see any lights of the cars coming and going.

There was 4 cars there spread out around the car park. Only one had any lights on and that was only the interior light. There were 4 men stood around that car presumably watching the action inside the car.

We parked up, Alice got naked and we waited, Alice getting quite impatient but I told her that we had to wait to be fair to the performing couple, or whatever.

Finally the interior light of the car went off and we could see the men walking away from the car. As per what I had read on the internet I flashed the headlight of mum’s car then put the interior light on.

That was Alice’s cue and she clambered into the middle of the back seat and took her dress (which was all she was wearing) off. Then she wound down both back windows and started slowly toying with her clit while I gave her a running commentary on any men approaching the car.

I wasn’t surprised when the men that had been around the other car had seen my actions with the lights and had turned and started walking our way.

“Press the central locking Archie.” Alice commanded.

“Already done.” I replied.

Once I told Alice that there were 2 men at either side of the car Alice’s legs spread wider and her rubbing got faster.

In the car’s wing mirrors I could see the 4 men staring in at Alice as she brought herself to her first climax of the evening. In the interior mirror I could see Alice’s face and she was definitely enjoying herself.

Then Alice got onto her hands and knees across the seat giving the 2 men at one side a great view of her pussy and the 3 on the other side of her a good look at her face.

“Can we touch you luv?” One man asked.

“Yes please.” Alice replied.

Seconds later I heard Alice gasp as, presumably, one of the men was touching her pussy. In the other wing mirror I saw one man get his hard cock out and put it through the car window. Soon I heard slurping sounds from her mouth. Minutes later I saw a semi pull away from the window and another hard cock go inside. On the other side of the car I was sure that the arm going in now belonged to a different body.

Judging from the sounds that Alice was making I knew that she was about to cum again. And she did, and the sounds that she was making made me believe that she had just swallowed another load of male cum.

Alice slumped down onto the seat and I saw the men step back a bit. After a minute or so Alice leant forwards and whispered,

“Fuck me over the front of the car please Archie.”

What could I say or do? As I got out of the car and opened the back door I said to the men,

“No touching okay?

The still totally naked Alice got out and came round to the front of the car where she looked at me then bent over the front of the car, spreading her legs wide as she did so.

“Give it to me hard Bro.” Alice said as my cock first entered her.

And I did. I had been hard since I parked the car and I was relieved to be able to get some relief.

In and out I pounded her pussy. I wasn’t expecting to last long but it was long enough for Alice to cum again and I’m sure that I filled her as she was cumming.

As we stood up Alice loudly said,

“Thanks guys, that was fun. We’ll be back as soon as we can.”

We got back into the car and I turned the interior light off only to see the headlights of another car across the car park flash.

“So Alice, is that what you expected?” I asked.

“And more.” Alice replied, “I hope that mum leaves her car at home when she goes away again soon.”

“So next time Alice, do you want the men to fuck you as well?”

“I certainly do.”

“But only if they wear condoms.” I replied.

“Of course.”

“I’d better buy a big box of them then.”

We drove home with the windows open and Alice searching the glove box for a new air freshener that we knew mum kept in the car somewhere.

Before we went back to school we did got back there twice and yes, Alice did let the men there fuck her.

The day of the party arrived and Alice had to decide what to wear. There would only be our class members and maybe their significant others there, no parents. So Alice decided that she was free to wear as much or as little as she wanted. The only prop that we needed was my phone which I made sure was fully charged.

Alice wore a skater style micro skirt and a top that showed her pokies all the time and if she bent forwards would show anyone looking at the right angle her nice tits. Other than 3 inch heels that was it.

We got a taxi there arriving fashionably late, finding that there was plenty of alcohol there and quite a few people were already slightly happy. We started circulating and I soon heard comments about Alice and her migraines. The photos and videos had been shared.

I got asked what it was like living with a sister that sunbathed naked and had orgasms in her sleep.

“She’s my twin sister, I don’t think of her like that.” I lied.

I also got asked by a few guys that I hardly knew if they could round and play some Nintendo games. I stalled them.

I was grateful when some girls started dancing, Alice included, and quite a few guys went and sat on the floor round the side of the room.

Alice wasn’t the only girl there wearing a short skirt but hers was more ‘floaty’ and as soon as the music got lively Alice started getting quite lively and the guys sitting soon got to see that Alice wasn’t wearing any knickers.

The dancing went on for about half an hour then it was announced that the buffet was open. People got food and sat around talking, me sitting not far from Alice.

Alice asked a couple of girls what they’d been doing over the summer break and we had to listen to details of a few people’s holidays. When someone asked Alice she briefly told them that we’d been to dad’s cabin by the lake but didn’t go into any detail. Then she added that I’d started a new hobby that she thought was rubbish. Then the best introduction to what was planned was when one girl asked what my new hobby was.

“Hypnotism.” Alice said, “but he’s useless at it, he’s tried it on me a few times and it doesn’t work, I must not be susceptible to it, go on Archie, try it on me here and all these people here will prove to you that it doesn’t work.”

“No, not here, no one wants to see you dancing around and telling everyone all about your school days.”

A couple of the guys said that they did then more agreed and eventually I agreed that I would.

“This is going to work Alice and you’re the one who is going to look silly, I’m going to get you doing stupid things, what song do you want to sing?”

“Don’t be silly Bro, you will be the one looking silly. Come on then, get on with it.”

I got out my phone and navigated to the app which had coloured circle going round and round. Even I had to admit that staring at it was a bit hypnotic but both of us had stared at it and not got hypnotised.

Sticking the phone in front of Alice’s face I told her to concentrate on the display. After about 20 seconds I started saying what I had read on the internet was supposed to work including telling her to close her eyes which she did.

When I thought that It had been long enough for it to actually work I started giving Alice some control orders,

“Alice, when I clap my hands 3 times and say the word ‘Rhubarb’ you will wake up and remember nothing that has been said or you have done since I said the word ‘Pineapple’. When I, and only I, say the word Pineapple you will do everything that I, and only I, say IF I prefix it with the words ‘Simple Simon Says’. If I don’t prefix a command with ‘Simple Simon Says’ you will not do as I commanded and you. If I, and only I, say ‘Simple Simon Says Pineapple’ anytime from now on, even years from now, you will you will do every thing that ‘Simple Simon Says’ until I and only I clap my hands 3 times and say the word ‘Rhubarb’.

I turned to the others who were watching and I said,

“Okay what shall I tell her to do? I know, Simple Simon Says scratch your left ear with your right hand.”

Alice did it.

Now put your right little finger in you right nostril.

Alice did nothing.

Again I turned to the others and said,

“Who can think of something that Alice definitely wouldn’t do if she wasn’t hypnotised?”

The was silence for a couple of seconds then one girl said,

“Tell her to kiss you passionately, no girl would do that to her brother.”

“Really, you want my sister to make out with me?” I replied.

“Yes.” someone said.

“Okay then, I guess that I’ll find out what sort of a kisser she is. Simple Simon Says says kiss your brother passionately.”

Alice turned and put her hands on the sides of my head and started kissing me. We’d done that hundreds of times over that last few weeks and that time was just as good as all the other times.

When we broke the kiss I said,

“Okay, that was actually nice, I didn’t realise that she could kiss so good. Now, what else do you want me to get her to do next?”

There were a few silly suggestions that I ignored then came one that I just knew Alice would want to do, one of the guys wanted her to do a cartwheel.

As he said that I was looking at a couple of the girls and their expressions told me that they knew Alice was knickerless. No one objected so I said,

“You really want me to tell her to do a cartwheel? She sometimes doesn’t wear any knickers and I don’t want anyone to be upset or embarrassed if she hasn’t go any on tonight. I know that Alice certainly would be if she ever found out what you got me to make her do. She’d probably kill me as well.”

Again no one objected so I said,

“Simple Simon Says get to your feet Alice.”

She did.

“Simple Simon Says go over to that big space and do a cartwheel.”

Every eye was on Alice as she went and did the cartwheel and everyone got a flash of her bare pussy as she did it. A couple of the girls gasped when they saw that she was knickerless but most of the guys and some of the girls gave her a clap which she didn’t acknowledge.

“Alice really must be hypnotised,” one of the girls said, no girl would do a cartwheel if she didn’t have any knickers on.”

I kept a straight face and looked at Alice to see if her face cracked. It didn’t, she was just stood there waiting for her next command. Unfortunately for her, her skirt had fallen back into place so she wasn’t exposed.

“Okay guys, what would you like Alice to do now?” I asked.

After a short pause one of the few girls who I didn’t think much of said,

“Tell her to take her top off.”

There was some cheers from the guys and smiles from a few girls. One girl who I had seen Alice talking to quite a bit said,

“No, you can’t tell her to do that, it would be humiliating for her.”

Two replies to that came quickly from 2 of the boys, both reminding the girl that Alice was hypnotised and that she would never know. One of the boys adding,

“Unless you’re going to rat on Archie, in which case everyone else will be saying that it was your idea Jenny.”

Jenny wasn’t going to risk that so she shut up and another girl said,

“Go on Archie, tell her.”

“But she’s my sister, I can’t let her be topless at a party.”

“Stop being a wuss Archie,” Toby said, “tell her.”

“Okay, Alice, take your top off.”

Alice remained perfectly still.
