Purely a work of fiction
Hope you enjoy reading it

It was a hot sunny day and Paul my 15 and Bob my 16 year old brothers and I their 14 year old sister were home alone as our parents had gone to work for the day.
None of us wanted to stay home in our flat for the day so we all decided we would go for a walk in the near by woods. As it was hot both my bros wore shorts and t shirts, and I wore a light summer dress.
We left home and made our way the short distance to the woods, it was usually quite a busy place but today it was surprisingly very quiet and there were a lot of paths that did not get used very much even on a busy day.
These paths my bros and I knew very well and usually walked on these anyway, so we arrive at the woods and just walked and see where we went, we walked on the little used paths and after about half an hour at which time Paul announced he needed to have a pee and Bob said me too, so they stepped off the path and with their backs to me said no looking and started to have a pee.
Well i was feeling in a cheeky mood and for a little while I had been wondering what an older boys cock looked like, i had seen little boys cocks before at the swimming pool when they had to go into the changing rooms with their mothers, so I quickly before my bros had a chance to do anything about it run and got in front of them to have a look at their cocks which I had not seen for a long time since they had started puberty and they started hiding them from me.
They were both still having a pee when I got in front of them and they both shouted at me to go away but I didn’t I stood there and looked at their cocks, Pauls cock was about the same length as Bobs but a little bit thinner.
Well anyway they both finished having a pee calling me names as they did so and Bob told me they would get their revenge on me.
We then continued our walk just walking where ever we went, my bros where walking a little bit ahead of me and whispering to each other, I could not hear what they were saying but I just knew they were plotting their revenge on me.
We walked a bit further and reached a little grass clearing in the woods a place we knew and had never seen anyone else there before, then they both stopped and turned round to face me and Paul said revenge time at which time Bob grabbed hold of me saying you see our cocks now we are going to see your pussy, then Paul grabbed my feet and between them they lay me down on the grass on my back.
They were both bigger than me so I could not do much about it even though I did struggle as much as I could but to no avail, Bob held my hands so i could not hit out at them and Paul sat on my knees stopping me from kicking out.
Then Paul lifted up my dress exposing my pink panties I was wearing, I had reached puberty myself and had grown quite a bit of pubic hair and a mound of it it showed through my panties but I had not got much right between my legs around my pussy lips and the form of my pussy could be easily seen through my panties.
Bob said to Paul go on then pull them off and Paul took hold of the top of my panties and pulled them down lifting my bum up a bit at the same time so they slid off me, he got off my knees so he could take them right off then quickly grabbed hold of my ankles and held them down so I could not start kicking.
So there I was laying on the grass being held down and my pussy on show to both my bros the first time they had seen it for a while since I started puberty, then Bob told Paul to open my legs which he did and exposed a full view of my young virgin pussy to them.
I could see that Pauls cock was getting hard through his shorts as he was in front of me, I guessed that Bobs cock would be the same, then Bob let go of my hands and quickly before I could do anything to stop him he grabbed the hem of my dress and roughly pulled it up and off of me, I was not wearing a bra as my breasts were not very big and it was a hot day so I was now absolutely naked except for my trainers.
I was cursing them both calling them everything I could think of calling them but they didn’t care but I was now calming down as I had nothing left for them to see so accepted it.
At this time I now needed a pee so told my bros and tried to get up of my back so I could have a pee, ok you can get up but you have a pee here in front of us, you see us peeing now we see you peeing Bob said.
So I got up into a crouched position and had a pee in full sight of both my bros, I could now see that Bob too had a hard on and to be honest i was now feeling cheeky again as I had got used to them seeing me totally naked.
So I tried to turn the tables back on them and said to them that i wanted to see their hard cocks now as they have seen me pee and with my legs wide open, they said no not a chance and started walking off with my dress and panties, so i decided blackmail would be my best option and shouted after them that I would tell Mum and Dad that that they force stripped me, they both stopped and turned and faced me and said you wouldn’t dare, try me I replied you know I would remember the time You broke my bike reminding them of the time they broke my bike and wanted me to say it was someone else.
Bob then got a smirk on his face and said ok but you have to pull our shorts and pants down, they both then stood in front of me and i was kneeling so my head was at about their crouch level I started with Bob and undid the button to his shorts then pulled the zipper down which revealed his blue pants which were being stretched by his erect cock I pulled his shorts down to his ankles and then done the same to Paul his white pants also being stretched by his erection.
I then grabbed hold of the top of Pauls pants and pulled them down to his ankles joining his shorts exposing his hard cock and then repeated the process with Bob.
This was the first time I had seen boys erect cocks and I liked it I noticed that they had a bit of a smell to them but not a horrible smell a light musky smell which I liked.
As said they were both about the same length when soft but Pauls a little bit thinner this was the same erect both were about 7 inches long now and quite thick, and I wondered how girls could get them in their pussies.
Both their cocks now also showed the end of them now they had poked out from the skin that was over the tips of their cocks when they had a pee earlier, and Bobs had a globule of something at his pee hole it was clear so I thought it was a bit of pee but it looked a bit thick to be pee.
I asked Bob what it was and he said it was pre cum which is something that comes out of cocks when boys feel sexy and want to have sex.
So you want to have sex do you then a stupid question in hindsight I asked, yes he replied and told me it was my fault he felt that way and without warning he pushed his cock forward and the tip of it went in my mouth and I got to taste the pre cum and it tasted very nice.
I was now feeling more than just cheeky I was feeling very sexy and could feel my pussy getting wet.
The only sexy things I had done before was fingering myself and rubbing my clit which I done a lot since I found out what to do, i had also like a lot of girls do put the handle of my hairbrush in my pussy which was really great.
I was about to find out how a boy gets his big had cock in a girls pussy, Bob pushed me backwards onto the grass so I was laying there on my back, he then got down and lay on top of me and with his knees between my legs spread them open, he was so heavy on me I could not move then he reached down between my legs and moved his cock and positioned it at the entrance to my wet pussy and started to push it in.
No Bob stop you can’t I’m your sister but he took no notice of me and carried on pushing his big hard cock into my pussy, he stopped after it was in a bit then took it out a bit just so the tip was only just in then again pushed it in again this time he went all the way into me and I felt his balls hit my bum and I screamed as when he done this it hurt me a bit.
The pain did not last long and the action then turned to pleasure and i stopped resisting and started to enjoy the experience, Bob Slid in and out of me getting faster and faster harder and harder until he suddenly groaned and I could feel his cock inside me start to throb and then I felt him squirt something in me i thought it was pee and said to him was that pee, no he said that was spunk.
I then put 2 and 2 together and realised what had happened, even though I was 14 I had not been taught about the birds and the bees properly Mum always avoided the subject.
Then before I could do or say anything else Paul had swapped places with Bob and he was between my legs he had easier access as i was still laying there with my legs wide apart so he just got down and without warning roughly shoved his just as long but thinner cock straight up my pussy and with one push he was right inside me all the way, and again slid in and out of my so wet pussy.
Unlike Bob Paul did not continue until he squirted his spunk in my pussy instead he stopped before he did and pulled his cock out of me I wondered what he was doing then he quickly rolled me over so I was on my belly, he then got back on top of me and repositioned his cock but this time it was not my pussy he went for it was my bum.
I didn’t have the energy to stop him he too was so heavy on me, he positioned his cock which was wet from being in my pussy and started to push it into my bum I didn’t like this and was screaming for him to stop but he just carried on pushing and pushing until his cock slipped into my bum, just a little to start with but bit by bit it slid right into my bum, it did hurt a lot to start but the pain did subside.
I still did not like what Paul was doing even though the pain had gone and soon i felt his cock start to throb to like Bobs had in my pussy and Paul squirted his stunt deep in my bum.
Paul slipped out of my bum and got my dress and wiped his cock clean with it and redressed himself Bob had already redressed.
I thought I would get my dress and panties back now so I could get dressed again but that was not to be, they just walked off leaving me naked so i followed them hoping they would give my clothes back before we got to the busier parts of the woods and started to meet other people, again this was not the case.
It was lucky it was a surprisingly quiet day as I had to walk naked all the way home so not so many people see me but there was enough that did including a few boys from my class at school which was very embarrassing.
