This is not a futanari, not even similar to one. Just visit the game's homepage or download a CG set if you still don't see/understand it. Or if you are too lazy/incapable of doing one of the aforementioned things: see post #989174.
fcma172 said: It most definitely is futa. There are no straps or apparatuses to denote a strap on, and other females in the same CG set are futa's as well.
... and even more: there is no penis, this is simply the optical illusion. This is not accurate censorhip.
