>>99357102sounds reasonable to me for a fertility Goddess to have a 9+ inch large bitch breaker on her. And if it's an intrinsic part of her body then it's more natural for "Mama to sodomize her little boy because she has needs too" than for her to equip a fake phallus.
On the other hand Shibi isn't any kind of supernatural being (besides being a bunny girl), and her dominatrix background also lends itself to putting on the strap to make me call her Daddy.
I also like the yin & yang balance of a usually doting caretaker overcome to satisfy an urge that's entirely physical, and a dominatrix deriving purely psychological pleasure from shoving an unfeeling tool down my throat.
