First threesome without me

Been a while since the Marius night and not a lot of action in that time. Katie goes and fucks Richard once or twice a week when she feels like it and he's around. Richard's had a mate staying called Adio for a few weeks and Katie really likes him. She had flirted with him a bit but he didn't seem interested. However, it turns out that Adio thought Richard and Katie were like boyfriend and girlfriend so once he realised it was just sex he changed his tune. So on Friday night I was working and Katie went over to Richard's for a quickie and Adio was there alone. Well I'm not sure what happened because she's not normally this easy but having arrived at 7pm, by ten past her knickers were off and Adio had slipped his dick in and was fucking her really hard on the sofa. She came really quickly and then Adio dumped his load in her, which isn't supposed to be allowed. After cumming Katie had a bit of guilt at cheating on Richard with his mate (not worried about me you notice) but it turns out the boys had set it up and Richard returned home shortly afterwards. Katie was a little embarrassed but as she said later "what's a gal to do?" so she went to bed with both of them and had a very enjoyable three hours. She was spitroasted with both of them taking a turn at either end. She had just got in when I got home from work at 11. So mine became the third cock in my wife's pussy in one evening. I suppose I should complain but I just want her to be happy and black cock at both ends seems to do that.
