Mike ran down the street to the Smith house across the street. He knew that they kept the spare key in a flower pot on the porch. He took the key and unlocked the door to sneak into their home, where the mother, father and two kids were watching some movie about the adventures of a father and his son and daughter in some sort of cyberpunk future.
The father, Leo was an engineer, he was well built and not really chubby. The mother, Maria was an architect, she was skinny and looked agile.
The oldest of the kids, Sonia was 16. She looked strong enough to bend iron to knots. The youngest, Tom, 14, looked kind of weak due to his exceeding thinness and thick eyeglasses, however he made up for his lack of strength tenfold with his speed and intelligence.
The family didn't see the muscular and sexy lion man watching from behind the couch, nor would they notice the changes the Chronivac would create as the 1 mile radius parameter finally started to effect them.
"Ohhhhh, Maria dear, let me lick you up" and without waiting for a response, Leo leans his head to Maria's cheek and starts licking her soft skin clean. "Leo honey, thank you! I could do with licking you up too!" Maria cooed, licking her husband's face back. As they did, their tongues began flattening with every stroke and became rough with small, feline hairs on the surface, Maria's chest began to flatten, and Mike can see something growing in her trousers.
Normally, they wouldn't really do anything sexual in front of their children, but the Chronivac had overrode the resistance as their grooming turned into tonguing each other's mouths, Leo reaching behind to slip his hand into his lover's pants to finger her tight ass while Maria pushed her hands past the jock father's shorts and briefs' waistband to grasp the cock cradled inside.
Sonia and Tom hadn't noticed the sounds of their parent's licking and tonguing each other nor saw their sexual gropings. Instead, they were to busy invested with the movie. As it was a DVD, the Chronivac began shifting the content as well, as the man suddenly changed into a lion, and the boy and the girl changed into a male lion cub. The two lion cubs, began to suck on the man's testicles as they jerked their partner off.
Maria and Sonia were slowly stripping off their clothes as their breasts vanished as a tent began to form in their pants
