My wife Julie and I recently played golf with three of my old army friends. John the youngest of our army crowd played with my wife and I played with the other two. Julie and John set off after us, but it became apparent they were playing quicker, so we let them play through. Around the tenth hole I thought I saw Julie's bag at the side of the fairway near to a long stretch of woodland. Walking off the tee leaving my other two old army friends chatting, I went to if they were ok. As soon as I got close to the tree line I could easily see Julie bent over holding onto a tree and behind her was John. Julie's short golf skirt was hitched and Johns shorts were round his ankles. Even from where I was stood, I could see Johns huge cock fucking my wife from behind. Stepping intot he woodland I got an even better view and heard my wife telling John she was close to cumming, When John replied saying he was too, she told him to fuck her asshole and cum inside her. Pulling out of my wifes pussy, he quickly slid his enormous cock up Julie's asshole and within seconds was cumming inside my wife. Julie made a sound I know only too well, she came moments after John unloaded inside her.
I walked out of the woodland with a huge hard on and strangely, a whole new sexual respect for my wife. She'd taken Johns massive cock up her asshole and sounded like she really needed it to make her cum. I walked back to the other two and told them I'd helped them find Johns ball. Really knowing I'd just watched him empty his balls inside Julie. We finished our respective rounds and had a drink with the guys. Julie made some excuse to visit the bathroom to "clean up". I knew it was to make sure Johns cum didn't show through her panties and skirt.
Back at home I didn't mention a thing to Julie, but when we had sex later on, I swear i had the hardest biggest hard on I'd had for years. We fucked for over an hour and Julie mentioned to me just how horny I'd been. I still haven't said anything about me witnessing them fucking in the woods and Julie as far as I know doesn't think I saw them.
Yesterday she asked me if we could invite John over to stay with us for a while, as he's struggling to pay for place near us. I told her he could knowing my wife would be almost certainly fucking him when I'm not around. And also knowing how turned on it's making me feel, knowing his huge cock will be deep inside the woman who I married, rear fuck hole.
