As i drove home i was thinking how lucky i was having a lovely family and wife.i spend a lot of time away from home with work and Anna never complains at all.We have a great sex life and still have a lot of fun together.kids are all in there teens and beginning to have there own lives without us parents so all is good. I pulled onto the drive and saw that Tony our builder was here hopefully finishing off the extension he was doing.As i opened the door i could hear some funny noises coming from the kitchen so i gingerly walked in and saw something i never thought id ever see, Anna getting fucked well and truely by Tony and enjoying every second of it.I was gobsmacked and froze where i stood.She was naked leaning over the table taking it doggy style,tits bouncing away and moaning for England.I stood and watched as they both climaxed.I went out and got in my car and drove off and waited for him to leave.when he drove out i went home and into my house,Anna was in the shower.When she came out i asked her y she was having a shower at such a random time of day,her answer was she had been for a run.I couldnt bring up what id seen, ant advice anyone??????
