During the last heatwave a few weeks back, I decided to thin out and chop down a large woodland area at the end of our garden. We live on a secluded estate, with our garden backing onto another garden. All our gardens are about 200 foot long and 60 feet wide are very secluded with trees and shrubs hiding you from other houses. I walked to the end of the trees and shrubs to see what needed doing. Separating our garden from the one we butted onto was a six foot fence. I examined the fence as it looked like it needed replacing in some parts. I looked thru a small hole in the fence into the neighbouring garden. There I saw a female, laying on a sun lounger in the sunshine. She was partly sideways on to me facing south to get the midday sun. She was totally naked. She looked to be in her mid-forties, with shoulder length blonde hair and had a good looking figure with an all over tan. There was another sun lounger next to her, but was empty. I also saw that they had a hot tub on the patio and a bloke was in it. I could hear another male voice coming from the open patio door. I decided to keep quiet and see what was going on. The male in the kitchen came out carrying a tray of drinks, he was also totally naked. He prick was semi erect. He walked over to the woman and handed her a drink, then he took one to the bloke in the hot tub. He came back to the woman and laid on the sun longer next to her. I decide as it was hot to go back to my house and strip off. My wife was at work, so I went back to my spy hole naked. As I got there the bloke in the hot tub was getting out of it. He walked and stood next to the woman, bent over and kissed her. She took hold of his prick and began slowly wanking him. He was soon erect and he put a hand on her pussy and was playing with it. The bloke on the lounger turned on his side and watched then playing. The bloke from the hot tub then moved and stood with his legs either side of her lounger. She sat up and took his erect prick into her mouth and gave him a blow job. She grabbed his buttocks as his prick went in and out of her mouth. After five minutes they swapped places. My prick was stiff and I slowly wanked it. I did not want to come just yet. She got on all fours as she got between his spread legs and continued sucking him. The second bloke got up from his lounger, his prick was erect and looked quite large. He got behind the woman and put a hand between her legs and played with her pussy. He then moved forward and put his prick into her. As he went in quite easily it must have been her pussy. He started to fuck her slowly at first then he speeded up, slapping her arse as he fucked her. He fucked her for a good ten minutes and I could hear muffled sounds of enjoyment as she took a breath from the blow job. The bloke fucking her withdrew and appeared to shoot his spunk over her back. He stepped away and she then straddled the first bloke going up and down on his stiff prick. He came up her with a shout. She sat on him for a few minutes and then got off him and went over to an outside shower by the hot tub. It was a lovely sight, seeing her soap her naked body under the shower in the sunshine. The two blokes joined her and both took it in turns washing her, paying attention to her large boobs and pussy. I wanked myself a bit faster and came shooting my spunk up the fence and over a bush nearby. She then went back to her sun lounger and the two blokes got in the hot tub. My wife was due home, so I went back to our patio and got two loungers out and waited on one naked. I heard her come in and she came into the garden. I told her to strip and take in the late sunshine with me. She went inside and I wanked my prick making it stiff again, thinking about want I had seen and how I was going to fuck my wife on the lounger. She came into the garden naked and took over from me and wanked my prick as she bent over sucking it at the same time. I told her to get on all fours and I fucked her doggy style. I came up her and she then laid on her back and I went down on her sucking and licking her clit as I fingered her sloppy wet pussy. She soon came and we both laid back taking in the rays. I did not tell her about my spy hole and wondered what else I would see in the coming days.
