He was good eye candy
I go out walking with a friend once or twice a week, usually in the mornings before it gets hot. I went to her place and she wasn't quite ready. She said she just needed to put on her running shorts and shoes and it would take a minute. She already had her sports top on.
I followed her to the bedroom and they have a bathroom attached to it and the door was partially open. Her husband was in there shaving. He was wearing a t-shirt and nothing else. His sexy, muscular ass was in plain view as was his gorgeous, thick cock. I got a good look at him for about 20 seconds when he closed the door to the bathroom after he heard us talking.
That was too bad. I was enjoying the show. I don't think my friend noticed that I saw her husband, because she was busy rummaging through her dresser drawers to get her clothes. I didn't tell her that I saw her husband's gorgeous cock and that the visual put me in a temporary state of lust.
I couldn't get the image of him out of my mind. I wish he could have just come out and fucked us both.
You could ask her if she is willing to share him
Well I don't know about "fucking the both of us" part. I am not really into sharing and prefer having my partner to myself.
I did have an experience where I was had the opportunity to see a friend of mines husband naked, and his body was as exquisite as he was charming.
It put a lot of naughty ideas in my mine and while those thoughts were rather erotic, the opportunity never seem to present itself.
