Family Holiday

I'm the oldest of 3, at 22 and single I went on the family holiday with some reservations. I thought I was too old for such things, as it was mainly for the younger children of families. In all, there were 15 in our family group 5 from my family and 6 from uncle Herbert and aunt Marie family any 4 from aunt Clares family. Her Husband Graham had left her years before, As I was the oldest of the children and the only adult under 40 I feared I would be made look after the younger ones. But aunt Marie and my mother Heather done that, while my father Robert and Herbert went fishing. Clare 41 went for long walks, so I left to do what I wanted to do. We were all staying for 2 weeks and there really wasn't much I like doing at the lakeside house owned by the whole family. It had been passed down from my grandparents to my mother and her 2 sisters. After 2 days I started to go for walks by myself and I came across Clare sitting on a large rock looking out across the lake. I said Hello and stopped and talked to her for a while and then continued on my walk. The next day I headed off again and met Clare on the trail and she walked with me for away and then we parted. The next time I was walking and met Clare she was undressing and going for a swim, she asked me if I would join her and I said I didn't have any swimming trunks. She replied saying Neither do I and I like swimming naked. I hadn't really seen a naked woman before only pictures and thought this my chance, so I agreed to join her. I undressed and quickly got into the water, I watched Clare walk naked into the water and we swam and played about a bit. Then she got out and started to dry herself with her towel, I got out but didn't have a towel and Clare started to dry me with her towel. While she was rubbing me down with the towel, I got a hard-on and she dried my cock with the towel without saying anything. After dressing we headed off along the trail. We came upon a flat rock in an opening in the trees, that allowed the sun to shine thru. Clare said she Was going to sunbathe on the rock naked and asked if I would join her. I said Okay and we laid side by side naked under the sun. After a little while, we dressed and continued our walk. Then we around the far side of the lake from the lakehouse. Clare asked me If I had ever had sex with a girl, No I responded. Then she asked If I would like to have sex with her, I didn't what to say. But my cock when hard as a rock, taking that to be a yes she started to undress. I soon undressed as well and she took the lead. I was a bit clumsy I know, but I enjoyed the fuck a lot and I blew my load inside her. She told me it was okay as she had her tubes tied years before and couldn't pregnant. After that, I would head off on a walk and meet Clare and fuck her almost every day, excepting rainy days and when others came along. On the family return home I would go and visit Clare for sex and she is always willing. I got a girlfriend and we have sex together, but I still visit Clare.
