Mums Friend on Holiday

I grew up with just my mum. She was pretty open about things. Just before my 18th birthday she took me on holiday. Her best friend 'Anne' (Obviously not using her real name) came with us. We were in Spain and in a small town near family. One day my mother went into the main town leaving me and Anne. We had been down to the local beach loads and on this day she said she wanted to go to one a little further away. I was fine with anything as long as it was sunny. Once we got to the beach there was only a couple of people there. I quickly realised it was a nudist beach. Anne had said she didn't realise but seen as we were there we should stay for a bit. She also said I wouldn't need to take my trunks off if I didn't want to. However she stripped down almost instantly. She clearly knew I was looking at her big tits. She had a small amount of brown pubic hair that had been neatly shaped. I've been known to have quite a large cock. Even when I was young it was thick. And on this day it did not let up. Watching Anne lay naked, my cock began to harden in my blue trunks. I lay my cock to the side in speedos and at this point you could clearly see the ridges in my straining member. Anne noticed too. She then said 'If you want to go sort that out in the sea it's ok'. I didn't know what to say. I also pretended it was ok. She then asked me to put some cream on her back. As I took her sun tan cream and rubbed it into her back. She laid on her front with her face turned facing my bulging speedo. There was a small wet spot my pre cum had made. Anne then said 'I think you need some bigger trunks' I can't remember exactly how it happened but we began joking about the size of my cock which ended up with her making me feel comfortable taking off my trunks in front of her. When I did, I noticed she couldn't stop smiling. 'fucking hell' she said. She then told me that I should put some sun cream on my cock to stop it from burning. Then without hesitating she poured some on her hand and started stroking my cock. It was clearly not being stroked for protection from the sun. I looked around and nobody was near by. As she stroked she made comments about my size. I somehow managed to hold out longer than expected until I exploded thick ropes of cum into the sand. I watched her rub her pussy faster as she quickly came soon after. We stayed on the beach for as long as possible. She jerked me off a few more times that day. Possibly the best birthday present I've ever had.
