My fiance and I are also looking for the second girl
I have no idea how to go about looking for a girlfriend other than the good old fashioned way, but I was talking to a friend the other day who said she saw posts in some paper looking for a third bisexual female member to their relationship.
If I wasn't in a relationship right now I would probably be interested in being the third party, but as it is, I don't know who else would even want to do this and there's absolutely no possibility of posting info in the paper XD haha!
I'm afraid there won't be many cute bisexual girls willing to partake in a threesome, let a lone a bondage related threesome...but I'll keep following the American dream!
Who knows?!
