This happened when I was 13, my parents were out leaving only my sister Kirsty age 15 and me, a short time after our parents went out Kirsty's friend Alice came by, she is also 15. As it was summer and warm I was wearing shorts and a T-shirt, Kirsty and Alice were both wearing tops and shorts.
I was messing around in my room and looked out the window and saw that the girls had taken off their tops and had on bikini bras and were lying on sun loungers sunbathing, as our house is set back off the road with nothing but fields behind it is pretty well secluded. so I decided to go down and see if I could get a closer look at their breasts.
As I walked out I heard Alice say is there any hair on it? and what size is it? I did not know what they were talking about so went and sat down, Kirsty answered that she did not know as it was some years since she had seen it, Alice then said should we find out and both started to giggle. I asked what the joke was and Alice said come over and find out.
When I went over Alice asked what size is it and when I replied that I did not know what they were on about she replied by asking about my cock, not knowing what to say I just mumbled never mind, but Alice said they should have a look and as Kirsty held me Alice pulled down my shorts and then Kirsty took off my T-shirt, Kirsty then held me and told Alice to take the rest off, so she took off my underpants leaving me naked.
They pulled me down onto the sunlounger so that they could have a good look, Kirsty told Alice to go ahead and Alice said look at his cock he has some black hair on it, and started to rub my balls which made my cock start to grow and stiffen, she said for Kirsty to look at my cock, it was now solid and about 4 inches, Alice held me while Kirsty now rubbed my balls and started to stroke my cock.
As she did this I relaxed and Alice let me go and Kirsty was now realy going at it and I saw her look at Alice and smile and when I looked round Alice was now naked and I saw my first pair of breasts and pussy, she had a small amount of fair hair on it and you could see her pussy lips, Kirsty told her to take over and soon Alice was stroking my cock and it felt great, meanwhile Kirsty had stripped off and I could now see her breasts and black bush of her pussy.
Alice asked Kirsty if she wanted to take over but she said no for her to bring me off, so Alice gripped my cock and was soon pumping my cock, after a short time I felt it ready to explode but they said never mind and soon I was shooting cum all over. They laughed and said it was my turn,
I was soon playing with their breasts but was not sure what to do with their pussies so Alice said she would show me and started fingering Kirtsy's pussy till she started moaning Alice then told me to do it to her so after Alice had lain back I slipped my finger into her pussy and found it was realy wet, I kept going till at last she told me stop.
What a day, we continued doing this whenever we got the chance, sometimes it was just me and Kirsty, for about four years till they found regular boyfriends but it was four great years.
We are all married know but boy I would not have missed that for anything.
