I Want My Best Friends Husband

Gossiping with my best friend I found I was always complaining about my husbands lack of sex drive, laziness, or just him being an asshole. I asked her why she never complained about her husband and she said she doesn't have anything to complain about. He's got the sex drive of a teenage boy, a big dick, knows how to pleasure a woman, takes care of her, works hard and stays in great shape. I was curious so asked how big his dick was and she showed me pictures of him. It was like an arm. At least 6-7 inches long and thicker than any dick I've ever seen. I've been joking with her that she should share him, maybe give him a threesome for his birthday, or for my birthday! Now every time I see him with his big muscular chest and arms I just dream of his big dick inside of me. If I ever got the chance I'd fuck him behind her back, but I think it'd be better if she just let me have some fun with them from time to time. I just wish I knew how to convince her that it would be fun to let her husband fuck my brains out.
