When it is warm , we like to drive out to different large woods . To go for a walk . We never use the paths . Always walking where other people don't go . Hoping to see the animals and birds . This day , we were walking through a thicket of bushes . We saw a movement , so we walked slow and quiet . Hoping to see a Fox . When we got closer , it was a young teen girl and boy , having sex . They had taken their clothes off . He was licking her pussy , she was having an orgasm . We stood watching and he got between her legs , fucking her . My wife wanted to stay and watch them . We saw him pull out and masturbate , cumming on the grass . That wa when we left . When we were far enough away to talk . My wife could not stop talking about it . How much she had enjoyed watching . It had made her feel horny . It had got me excited . She wanted me to fuck her . We stopped and kissed . I had my hand up her dress , rubbing her clit . She was wet through . I only ralised how horney she was . When she was cumming , almost straight away . I dropped my jeans , Pulled her panties , and we got on the grass . I had never felt so arroused . I slid in to heer pussy . It did not take me long to cum . We dressed and carried on walking . My wife was still talking about what we had seen . We got back to the car , and headed for home . Sitting in the car , he pulled her panties down , asking me to finger her pussy . On the way home , he had an orgasm . When we arrived home , she was ready to fuck . We both undressed , got on the lounge rug and fucked . After this , we had some food . All the time he was talking about watching them fuck . She wanted to fuck all the time . I was not ready . I licked her pussy and finger fucked her . Later we fucked . This was the only time we saw anyone fucking . As my wife said . It was better than watching porn .
