Hold on, hold on, hold on. Now it seems like we may need to clarify a few things then. I futa, or futanari, requires a dick and a pussy. Occasionally there are also testicles. A trans, or transexual/transgender, individual, requires that said individual once had a dick, but now no longer does, or used to not have a dick, but now does, or has or does not have the required genitalia of their chosen sex (hence transgender).
So are we talking cocka and pusspuss as a possibility, or cock, balls, tits, no puss, as a possibility? Are we saying traps are a no-go, so a femboy like Astolfo is not happening, or that trans are a no-go, so someone like Poison wouldn't show up?
