Let me know if you find a TS provider for this! I know lots of Cis females who would love it but hard to find a good TS provider

Still looking for a threesome w Gen woman and hot TS

I've had a several 3somes with both genetic & trans girls and two trans providers at once. In my experience you need to open the dialogue and ask in subtle ways if you can't find specific ads for them. Things to look for; traveling providers, especially those traveling with others, trans girls who are more or all top, genetic girls who do anal/DP and are open to 2 men or group sessions. Social media has improved this scenario, genetic and trans providers who post clips as "content creators" often look for others to shoot new content with.  

There's hundreds of secondary content creators who mainly shoot with and for others. These secondary people often work for free just for the hook ups or exchange of content. They wear a mask, cover tattoos and other identifying marks, they may even mask their voice. They're usually at least in average to great shape, are very well hung, a great bottom, a girl with huge rack or ass or deep throat ability or trans with that or a huge cock. It's possibly another reason reviews are down, instead of paying for providers, these people are literally living the dream lol. I've seen mainly men but some women and trans as secondary content creators. The main things they post on their pages is the collaborations they've done. Some also do this to get their page started.  

This could be a way of making it happen?  

Hope this helps...  

TV Alessandra Foxxx will do a 3 some with a CIS woman.  She has a healthy list of reviews on TER.
