Dennis had watched with panache, and decide to activate HIS monster tf too.
Like his brother David had done before him, He got up his monster tf on his phone, and activated it, he did.
Almost immediately after he did so, one after another, all his clothes vanished off his body, like David’s had, then, his penis deflated, shrivelled up, and vanished, replaced by a covering of scales, which soon spread over his body, like his brother. The scales mostly retained the skin colour, but with a slight reddish tinge to them.
Like his brother, he gained muscle, and grew the short stumpy tail above his butt.
But to David's surprise, Dennis' feet had 4 toes, And his hands had 3 fingers, his ears pointed, and short stumpy spines grew on his back; yet instead of brown, they were blue, like the colour of his scales.
His face pushed and melded into a snout, and grew claws on his hands and feet.
Dennis was a monster, similar to his brother.
Everyone was amazed.
But David was baffled about why his brother had the same tf as him, but slightly different. "Why is your form slightly different to mine?" he asked his brother.
"Well," Dennis said, "Just because we're twins doesn't mean we like the same things, or have the same monster forms. But hey, it's cool." he said, giving his brother a noogie.
