Jeff let out a little yell of shock as Nibbles picked him up, the large male mouse giggled as he looked Jeff over.
“Man, I’ll never understand why human balls are so huge!” He laughed as he held the small quadrupedal human up.
Jeff, terrified of being held up so high off the ground by the furry hands, finally noticed that his and his dad’s balls were huge! Almost as big as their thighs! He vaguely remembered that mice had that before the change.
“Nibbles! What’s going on?” Jeff called out, shocked to not hear his voice leave his mouth, but instead it was a series of high-pitched squeaks! He looked back into the cage and the high pitched voices of his family had also changed to be little animal noises.
Oddly, even though the men were changed with their larger testicles, the two women of the family still had their breasts, which seemed a little odd as they ran in all fours. Though it was probably because they were still, at some level, human.
