Duncan and Emma..
A few days ago, I got a phone call from Duncan, saying that he had a new slut coming to visit and could do with another cock to keep her satisfied. As I was in the area, I arranged to join them and was soon helping Duncan fill Emma's mouth with cock... Then Duncan got Emma to turn over and soon had his cock lodged firmly up her arse; we took it in turns to give her a spit roast until Duncan eventually came over her cock and I did the same over her face...
