As Palador and Galla chitter at each other, Galla suddenly feels herself becoming aroused from the smell of her brother. An unfamiliar pressure builds up in her crotch, and looking down between her legs she sees a male mink cock begining to poke through her brown furry sheath.
A penis?, she thought confused... A male? I'm now a male!!!
However, she, now he, isn't given much time to absorb it all in, as she find her mind becoming clouded from desire for the white female lying next to him. Part of her is revolted by this, realizing the female was her brother. But her smell is so intoxicating!
Meanwhile, Palador is oblivious to this all, too busy grooming the tail of what he/she still thinks is her sister.
That's when she feels something rough and slimy rubbing between her legs. What the?! She looks down to see Galla licking and sniffing her crotch. And then, she notices the Galla's fully erect mink penis.
She stands up to all fours in surprized confusion. Then, before she knows whats happened, the male jumps ontop of her and pushes into her new sex.
Oh no, not again!, Palador thinks.
