Sorry, this is quite long. I'm currently on holiday in Greece. It's an appartment block with 8 rooms and a pool, so quiet and private. I was lying in the sun today while my wife was having an afternoon nap. At the end of the pool was a young couple, mid 30s I guess. I'd seen them around. Swedish I think. He was typical Swede, she was short, cute with shoulder length blonde hair. Not stunning but curves in the right places. So, he got up, got his stuff, kissed his wife/girlfriend and left her reading a book. I went for a dip in the pool to cool off. As I'm swimming up the pool, I realise I can see right up between the girls legs. She's wearing a sunshine yellow bikini with her hair tucked into a sky blue baseball cap. The bikini is quite small. After a couple more lengths, I stop and try to nonchalantly stare. The bikini is perfectly showing her pussy lips. Without thinking, I loosen my shorts, take out my cock and start stroking. There's noone around but us. The water is cold but after a few tugs I'm hard. I'm jerking away, looking right at her pussy, when I realise she is looking at me over the top of her book! She's caught me jerking in the pool! I'm afraid she's going to go crazy at me being an old pervert. She must see the horror on face because she looks me straight in the eye, smiles and winks. Then she does something amazing. She pulls her knees up and pull her bikini bottom to the side showing her lightly haired pussy! With the other hand she starts to play with herself! I'm jerking away like crazy and she is watching me intently. It's all to much and I start to cum. I have to cum in my shorts so I dont mess up the pool. She obviously can tell I've finished as she winks at me again, smiles and goes back to reading her book. I struggled out of the pool and had to shower the cum out if my shorts so my wife won't find out. I have no idea what will happen when I next see this young couple!
