Once their orgasms were over Tanya, Amy and Carmen talked about something Chuck and Mandy couldn't hear. Soon after, Carmen ran away and soon returned with the Chronivac with her.
"We had a great idea. See and be surprised." Carmen said before typing something into Chronivac. Within seconds the transformations began.
It all started with Mandy separated Chuck, leaving him with a vagina between his legs. Mandy's old bottom half grew up behind her balls, the part where she was attached on Chuck, just her breast went down and merged with her ballsack so that she had a huge smooth hairless ballsack with nipples. What was left over from the top of her took on a cinindric shape and grew to 8 feet, becoming a huge cock that had legs, arms and a face at the tip. Her arms also moved downwards so that they were attached to the sides of her balls.
Chuck went the other side when breasts grew on his chest all the way to O-cup, his hair lengthened until its tip reached the top of his ass. He also gained several curves becoming a very attractive woman.
Soon after, Amy and Tanya were transformed. For Amy the only difference was that her balls quadrupled in size absorbing Tanya's legs, whereupon the body's body acquired a cylindrical shape and elongated, making her an 8-foot cock attached to the same pair of testicles as Amy.
Carmen turned last when her bottom was inverted, leaving her with her ass in front of her while her cock pointed back. Then her legs were covered with hair, her joints changed and her feet became hoof. Her lower part extended and acquired a second pair of legs. The inverted legs and ass in front of her also came extended in front of her. Then a tail grew over each of her asses, as well as another cock between her new legs. In the end she was what appeared to be a centauress, but with her human part coming out of the middle of a horse's body with butts on both sides. In her two asses, instead of assholes, she had huge vaginas. Her two cocks were also hard and their tips touched under her.
"What did you think, Mom? Now is your chance to fuck Dad." Tanya said
Mandy smiled and said "What do you think dear? Will you want to feel me inside you?"
Chuck took a good look at the cockwoman Mandy had become and was interested. He was a woman now and only her wife's shaft was already bigger than her entire body, but she believed there was something else that she still didn't know about her transformation that would make it possible. So she said "Come and get inside me, if you can."
Mandy bent down and pushed her tip against Chuck's pussy, which was difficult at first but she did it after her husband took her foreskin and pulled.
Chuck could feel very full as Mandy was entering her more and more, with her belly swelling a little, until she felt the tip of her wife hit her ribs from inside. She thought Mandy would stretch her belly just like the other women she entered, but instead, when she pushed more of herself inside, Chuck's body began to stretch, doing so until Mandy was whole inside her.
Mandy got up, lifting Chuck to fuck her better, but Tanya called her, who turned to her daughter and approached her as requested.
Tanya then took her tip behind her dad and pushed right next to her mom. To their surprise, Chuck's pussy stretched even more allowing Tanya to get into her too, going all the way in.
"Hello mom, how nice to meet you here inside dad." Tanya said inside Chuck
"This is amazing my daughter. I didn't think there would be room for the two of us here." Mandy said
Meanwhile, Carmen went over to Amy and pushed her backa sspussy into her friend to get her into it. She kept pushing, feeling Amy's tip go under her torso and keep going inside her until she went all the way and her tip came out of Carmen's front asspussy. She bent and stretched out, reaching out and placing a hand on Amy's urethra.
Amy passing through Carmen's horse body, while Tania was with her mother inside her father, both leaning on their shared balls and feeling what the other felt. That's how they felt that Chuck had an orgasm. Even so they didn't stop fucking and soon it was Mandy's turn to come. Carmen also came just before Amy and Tanya's simultaneous orgasm.
Chuck was impressed, because she had her wife and daughter inside her coming absurd amounts of cum, that made her have another orgasm.
When the orgasms were over, everyone relaxed, totally satisfied for now. The most impressive sight was Chuck, who, even after Mandy and Tanya left her pussy, did not let a single drop of cum escape her, leaving her body split in two by a huge sphere formed in the middle of her body by the cum.
