First time

I had a friend who told me that he wanted to fuck my wife I found an opportunity to suggest to my wife but she said no ,.withing the next 4 weeks I would mention it to her and she would say no
Finally one night, my friend came over to visit late
She went to sleep, about an hour later my friend was really horny and hard he made me touch it it was big
I went to the bedroom and took away the bed cover that she had o ver her body and she was naked
I I got closer and asked her if she wanted to fuck him she said in low voice, yes
I asked my friend to get in the bed with her
I closed the door but I could hear her moaning of pleasure
I open the door and he had her doggy style he wasn’t moving at all she was doing all the work I was very hard and came just watching them
