While fucking my wife the other night, I was watching her 36c's bouncing backwards and forwards, and asked her where she wanted me to cum. I wish we had someone kneeling right next to us right now, she said. 'Like who?' I replied. ' We have a guy at work, around our age' (we are both in our 40's) she said ' He's faithfully . married, so he will be safe from STD's ' (as this is the one thing that stops her from swinging,) ' So what would he be doing? watching us?' I said 'Yes, I've looked at his crotch, and he looks like he has got a big cock, so he could have it out, kneeling there and slowly wanking' Well this made my cock even harder. We both like to watch porn, and the best part of any film, is the money shot, we both watch for it, even fast forwarding sometimes just to see it, obviously heavy cummers are our favourite. 'And would you help him out?' I asked 'We both would she said, I would stroke him sometimes, then when he's touching my nipples, I would push your head forward a bit, so you could lick the head a bit'. 'That sounds like heaven to me,' I said, She knows I've only sucked one cock before years ago before we met, 'Then if you are a good boy, I will put my hand round his bum and pull him forward so the head pops into your mouth' This was nearly making me cum, I slowed down fucking her, and mumbled 'And where will he cum?' 'He will be a heavy cummer, and will cum all over your face and my boobs' she said. As she said this we both cum really hard, I felt her cum soak my balls, as I cum what seemed like a gallon of sperm inside her. We both came down from our plateau, and I said to her 'Book it up, I want this to happen' If enough interest I will tell you what happened when we met
