I would like to tell you a story about the first time that we ever did anything related to swinging, and it was an MFM threesome.
We had decided to try things out, after having talked about it for a couple of years, mostly in bed while having sex, so I took a couple of good pictures of her, and tossed them up on Craigslist (which we now know we got VERY lucky with..)
So, of course we got a ton of replies, most of them just simply dick pics, that we pretty much ignored. We were originally looking for another couple to play with, but we got a reply from a single guy that was actually intelligent sounding, and could write more than just a single sentence!
We chatted with him over email for about a week or so, and then she got his phone number and was texting him. Another week goes by (I saw all the texts, they started out pretty tame, and then got really detailed), and we decided to meet up for a drink and see how it went.
