Help finding a story - Threesome Neighbors

[gigglebox46]

I read this one about 3-4 years ago, but I didn't finish it and havejt been able to find it again. This woman's husband sucks, and I'm not sure if he emotionally or physically abused her, but whatever it is her attractive new married neighbors take her in. I think she thought the male neighbor was flirting with her til she found out he had a wife, who was equally flirtatious with her. At some point they go to a club together, she gets drunk and sits on the man neighbor's lap and unconsciously humps his leg. He tells her if she doesn't stop there's gonna be sexytimes. And there is indeed a three way. That's where I left off, but I'm 90% sure there's more to the story.
