Trying to remember a story. Help please

[AzureShin]

I few years ago there was a series I really liked. It was about a group of 3 friends, i remember one of them was a military wife. They got into all sorts of interesting things. One story was about a bet that was made with and they had to be sex kittens for a day which ended poorly for one of the girl's boyfriends. One of them they ended up fking a bunch of teens. I remember that one of the lines was about telling them to come at exactly 4 since the nosy neighbor would be gone. Can anyone help me? I can't find this story series anywhere.
