I to have been trying to organize either this or a mmt but have had little luck. Honestly its the trans girls that are the issue, not so much the girl or guy. I have a couple girls that would do this no problem but its very difficult to find a trans girl who will leave her flat, fuck a girl, cum and not be a dominate powerhouse in the bedroom.
I find getting a good trans in general to be much harder than getting a regular working girl and when you add in special requests its even harder.
