Immediately, all 3 of them began to experience their tfs all at the same time.
Nigel's ears pointed, almost becoming bat-like.
Then, he got a third eye on his face. His teeth became long and sharp.
There was a sudden loud rip, as a huge long green lizard tail sprouted from his behind, splitting a huge hole in his slacks.
Nigel saw his toes burst from his hiking boots, as his feet expanded 3 shoes sizes bigger, and sharp claws grew in place of his toenails. and his hands gained the same sharp claws as well.
And then, Nigel grew, to double his size, splitting his clothes to scraps, and then, his skin turned a pale lavender, and his hair turned a vibrant neon blue.
Wilma's hair changed from brown to neon blue, her bottom half turned into tentacles, her arms became long, and her hands became 3 fingered, with claws, her neck grew, her eyes became a cyclops eye, and her skin turned cyan. Her clothes seemed to become part of her body; becoming different coloured markings on her body - dark blue around the tentacles, yellow round the torso, and black round the tentacles tips.
And Billy's hands transformed from five digits fingers to three digits fingers.
Then, a short stumpy tail popped outta his pants, like with his dad.
His footwear disappeared, revealing his bare feet had 2 toes on the feet, then the rest of his clothes vanished.
His eyes became a cyclops eye, like his mother's, then he gained 2 blue tentacles under his arms, and then, he gained pointy ears, an extra pair if eyes, his nose pointed, and his teeth became sharp, like his dad's.
Finally, his body turned a pale cream colour, with the exceptions of his hands and feet - his feet turned lavender, like the colour of his dad's monster form's skin, and his hands turned cyan, like the colour of his mom's monster form's skin.
To finish off, black short spikes grew on his head, and his hair turned neon blue, to match his parents.
They were all monsters!
"That was amazing!" Billy said.
"Yeah," Nigel said.
almost IMMEDIATELY, Billy noticed the scraps of his father's clothes disappearing. "Dad, your clothes!"
"Don't you worry bout them, son." Nigel said. "When people become monsters, their clothes disappear and/or get destroyed as they tf." "But do not worry." he added, "the clothes magically return to their owner's homes, as if they were never destroyed to begin with."
Nigel noticed the spot on his crotch where his dick used to be - his dick had gone, replaced by a vagina.
[He had failed to take into account that when males became monsters, their penises were removed or changed into vaginas.]
Billy had noticed too that his penis had became a vagina too.
Yet, when Nigel compared the transformation of his wife to his transformation, he noticed that when he transformed, his clothes split, and ripped to shreds, then vanished, but when Wilma transformed, her clothes seemed to become part of her body.
“Hmmm.” Nigel mused. “Seems that the monster transformations of males and females have different effects on clothing. I'll have to test it after we get home.”
"I look amazing, honey," Wilma said, "but, what if anyone..."
"Don't you worry, honey," Nigel said. "I set the tfs for all of us so that only we see ourselves as monsters. Other people who we pass will just see us as humans."
"You certainly did think of everything, Dad!" Billy said.
"Sure do, son." Nigel said. "Now let's go hiking!"
