Big Bad Futanari Wolf

On your way to grandma's house you meet a friendly wolf with much to say.
She suggest you pick some flowers on your way.
But before you could turn to say goodbye,
the friendly wolf had gone awry.

Late to arrive, nearly half-past five,
grandma in bed, bonnet on head.

Her face concealed,
terrible secret soon to be revealed.

Witty answer for every question,
most sinister grandma's expression.

With one last step closer, grandma it is not, no sir!
