The clowngirl took one of Joy's hands in her left, and one of Julie's hands in her right. Both girls gasped as an almost tangible tingle of energy went through both of them. The clowngirl guided Joy's hand to her breast, smiling as Joy began to squeeze and fondle her left breast. The clown didn't have to guide the far more eager Julie's hand. Of her own volition, Julie's fingertips found the edge of the clowngirl's bikini bottom, and she began to play at the lips of her grease-painted object of sudden lust.
The clowngirl leaned in, kissing first Joy and then Julie passionately. The girls began to give into their lust, their fingers groping the clowngirl, their tongues intertwining with their new friend's.
They never heard the quietly uttered, "Metamorpho!" from the ringmaster, nor did they notice the beam that shot instantly from the wand, hitting their companion.
They barely noticed her changing at first. Truth be told, they were so enveloped in their passions that they failed to notice they were kissing and groping each other almost as much as the clowngirl.
The clowngirl's body swelled, her beastial side tearing out of her human form. Her bikini fell away, her shaven muff blossoming fur just as the other clown's had.
Still quite impassioned, Julie and Joy didn't seem to notice. If anything, it seemed to fuel their fervor. By the time either of them had noticed anything amiss, their companion had become a fully formed werewolf.
