How long did it take for you and your AP to become "serious" rather than just fuck buddies?

We met as swingers. I was barely interested but my SO wanted it with his SO so I thought what the hell, he's tall at least. The first time we fucked, during a swap, we looked at each other after like...woah what was THAT?? And I am a very jaded and slutty girl, and this was...different. The second time sealed it. We looked at each other and said, we are FUCKED. We had this electric and chemical and mental thing, so much so, I became the first woman he ever cheated with in his 25 year marriage (and mind you he has no DB and fucks other women, with his SO's permission, but with me, well, he risks everything to see me, it is so much more than sex. But also the sex is the best ever). We are going strong over a year later and we are in love.
