Jeff wanted to head out into town and cause chaos with the Chronivac. He knew he could just do it from home, but were is the excitement from watching people change and react live. He use the Chronivac to upload itself onto his phone. He made his way to the stairs leading down to the living room. Jeff stayed in the middle of the stair way, having enough sight to see his family in the living room while still remaining hidden.
Jeff began to alter his father Gabriel, his mother Emily, and his 10 year old sister Julia. He confirmed the changes and watched as the began to change and react.
Jeff watched his father yell as 4 breasts began to swell out from his chest. His mother screamed in panic as all the hear on her head disappeared. Julia freaked as a cock began to replace her clit. Jeff smiled, he couldn't wait for the rest of the changes.
Gabriel panicked as his lower half changed into a tauric configuration. His cock and balls disappeared being replaced by a hungry cunt. He gained another cunt on his front. More breasts came into existence, he gained an extra set on his front giving him 6 now head sized breasts, his lower half gained 12 torso sized lactating tits, and all along his back from his top half down the length of his lower half he gained 20 torso sized tits. His feet turned into monstrous blacken hand like claws and growing outward along his legs blackened fleshy spikes grew, the tips of which are a neon green. His face twisted and altered to that of a young women.
Gabriel could feel it, he was no longer a man he was a women now, a women who is slowly going into heat. Her body felt so sensitive, she was desperate for some to touch it and fill her needy cunts with their cocks. She felt more changes start to pass through her finishing up her monstrous form.
Gabriel felt her spine extend out a split up into three long tails that ended in blades. Spike grew out of her spine running down her length ending at near the tip of her tails. She grew 3 sets of arms below her originals and all her arms changed to be similar to her feet. Along her arms and shoulder she grew more spikes. Her hair lengthen down her back, turning green, and growing spike and large sharp teeth out of it. Her tongue lengthen out of her mouth and grew alien ripping. She grew a second set of eyes, which along with her original started to glow green. Her upper torso grew curvier and muscular. The nipples on the top most tits on her upper body turned into mouths with monstrous tongues. The nipples on her bottom most on her upper body changed into cunts. The cunt on her front grew a monstrous tongue. And lastly 8 of the tits on her lower body grew black and green tentacles, the tentacles came from the inside coming out of her very stretchy and fuckable nipples.
Gabriel let out a lustful moan/roar as the changes ended for her and her pussies leaked lots of girl cum.
Emily was panicking as her head turned into the head of a cock, her mouth becoming the opening. Her tongue became a tentacle as 3 more grew in the canal as well giving her 4, to help her hold herself in someone womb. The rest of her body quickly followed, with her breasts disappearing, her arms shifting downward, her legs becoming her ball sacks. Her arms ended down at the base of her shaft body just before her balls. Emily felt her pussy close up before expanding outward into another but longer cock. Emily felt her "face" on the other cock allowing her to see from it. Lastly she grew another ball sack giving her three which quickly began to inflate as they began to produce tons of cum.
Emily with no real means of movement except for using her arms to drag her, she hoped she could remain stuck deep in some ones needy cunt.
Gabriel used her tails to pick up her cock wife from the balls, before slamming her into her drooling cunt. She used her tails to control the thrusting of her wife. The longer cock Emily was grinding between Gabriel's large tits, reaching all the way to her front. It was clear that Julia would be taking the second head of her mother while plugging up her father's frontal cunt.
Julia felt her self grow older becoming a horny 18 year old. Her lower half became that of an anthro horse, her cock and cunt changing accordingly. She grew more tits, the same amount as her father. Her torso lengthen till she knew her nipples wear aligned with her father's. Her ass and hips expanded, while her thighs thicken to allow her father better grip to hold her. Her nipples changed into cocks already leaking from arousal.
Julia was quickly picked up by her father, who lined her cunt with her mother's head and her cock to his cunt. Julia began thrusting into her father at the same time she felt her mother thrust into her own needy cunt.
Gabriel lined her daughter's cock nipples with her mouth nipples, her fuckable nipples and her cunt nipples before squeezing Julia in a tight hug causing the cock nipples to enter her needy nipples.
With his family thoroughly distracted, Jeff began to make his way out of the house to cause chaos in the city for the day. Jeff wanted to slowly cause chaos day by day in the city, so her will return home to sleep, before heading out for the next day of chaos. With that in mind he made it so no one can leave the city and no one outside the city will intervene. Just as he was about to leave, he decided since he was going to be seeing his family fucking a lot he might as well continue to make things interesting.
Using the Chronivac he set some rules for his family. 1. They can't leave the house. 2. Their sexual fluids (cum, pussy juice, breast milk) will cause them to transform/ mutate more. 3. They can't merge with each other, but any one who enters (beside himself) is free range to merge. 4. They can't swap genders or gain things from the other gender. (Gabriel will stay as a Female, Julia will stay as a Herm, and Emily will stay as a Male.) 5. The house will grow on the inside to accommodate any size changes to the family. 6. Jeff will be immune to the transformative fluids and immune to merging.
With that done Jeff gave one last look at his family and saw a slowly growing puddle of liquids underneath them. Jeff smiled, happy at the monsters he made out of his family. Jeff went out the door and couldn't wait to come back in the evening to see what they have mutated into.
