I was a late starter physically at least, but my mind and my hormones were raging
I started to get those budding breasts when I was 11, but by the time I got to 13, they were still kinda small. 'A' on a good day, but really 'AA'. I didn't have much in the way of pubic hair either, and I didn't like what I did have because, well, you know, it gets kinda sticky right? Now, I have a real good friend, but this isn't about her. Anna has a sister called Sarah who is three years older than we are. Sarah had a room to herself, but I was in awe of her. She was tall, beautiful and seemed to me to be the perfect woman. She had beautiful breasts and curvy hips and a flat tummy, everything that I didn't have. One day Sarah took me and Anna swimming only on the way to the pool, Anna got her period and couldn't swim. So it was just Sarah and me. We hung out in the pool for a while while Anna decided she would take the bus home.
After a while, Sarah suggested we go to the sauna. It was my first time in a sauna and DAMN it was way too hot for me. In no time, we were both sweating like crazy. Sarah removed her top and we lay there side by side for a while. I remember seeing the sweat run down in little trickles between her boobs and it got me all horny. After a while it was too much heat for me and I wanted to leave. Sarah suggested we go to the steam room as it's less agressive. I didn't really want to, but I thought what the hell.
In the steam room it was much better and we had the room to ourselves. It wouldn't have mattered anyway as you couldn't see across the damn place. Sarah again took her top off and encouraged me to do the same. I was way too shy to do that, but she kept on and I guess I just wanted to be half naked like she was. I slipped my bikini top off and she looked at me and smiled. She told me I had 'lovely little titties.' And then she brushed her hand over my right boob. The effect was electric. I suddenly flooded in my bkini bottom! Sarah just started talking dirty.
She said 'I bet you cum real hard when you play with yourself don't you? I would love to see your pussy.' I kinda got into it and tried to tease her back by tugging my bikini down and trying to act all grown up by saying 'Like this?' As soon as I did she slipped her hand between my legs making me yelp. Then she almost immediately found my clit and I was lost! She rubbed and teased my little bud so well. I sat next to her with my legs apart and her hand in my bikini bottoms. Then ever so gently she pushed her finger up me. I wanted to feel her so I asked her. And I wanted to talk dirty so I said 'Sarah, I want to touch your cunt.'
She spread her legs and took my hand and put it in her bikini bottoms. She had no hair at all! Then she showed me how to push my finger up inside her. Then, well, we were just sitting there fingering each other with our heads on each others shoulders. Now and then we would kiss and then she reached round me and pinched my nipple which tipped me over and I cummed long and hard into my bikini bottoms. Sarah tensed up too and cummed. Then she asked me to watch her pee. She squatted down and just did it in her bikini bottoms. It looked so sexy that I wanted to do it too. But she made me squat over her.
Sarah taught me a lot about sex over the following year. I never did anything with my best friend, but I fingered Sarah a lot and she did me. I even got to finger her after her boyfriend had cummed up her. Sarah loved peeing. She would do it in her knickers or her tights and loved it when I peed on her.
I had a great year with Sarah.
