When we were still lying in bed the next morning, Bonnie and I talked and decided we were both fine with Annie joining us occasionally for sex and later when we asked her, not only was she good to join, she even suggested that she might enjoy being part of our bets occasionally. I looked at Bonnie, Bonnie looked at me and we both nodded so we told Annie we liked the idea too. After talking for a bit about the only thing that Bonnie wasn't sure she wanted to try was going down on another woman and Annie wasn't really interested in anal but they were open to pretty much anything else.
Now that we were all involved sexually, the frequency of our 'bets' died down over the next month or so but the frequency that two or all three of us had some really good sex went way up. It turned out that the 'quiet' Annie had a definite kinky streak that both Bonnie and I totally enjoyed. One Saturday, the three of us had been out to a party but it wasn't great so after a few drinks, we'd come home to have a few more and a few 'edibles' as well. Now all three of us were on the couch, somewhat watching tv and randomly touching/teasing each other when suddenly Annie said, "Anyone else horny and up for some fun?"
When both Bonnie and I agreed, she said "Ok, I was thinking of an 'anything goes' evening."
Bonnie and I weren't totally sure what she meant but with the buzz we had going, we were pretty sure it would be fun so before long we were all naked and on the bed. "What exactly did you mean by 'anything goes'?" I asked Annie.
"Well, we know what we've done with each other but usually we kind of 'plan' what we're going to do. I was thinking we just start and do whatever comes to mind at the time."
Bonnie giggled and blurted out, "I want to get eaten!" followed by Annie saying "I want to get fucked!"
I flopped onto my back and said, "I think I can do both - how about Bonnie straddles my face while Annie rides my cock.
Bonnie quickly nodded and was moving to straddle me when Annie quietly said to her, "Or maybe I could eat you while Dave fucks me from behind?"
Annie and I talked a few times when Bonnie was out and she'd mentioned that she'd been thinking she might want to try licking Bonnie's pussy but wasn't sure if Bonnie would be into it but I guess she'd decided to see.
