"I have an idea sister." Sophie said suddenly, causing Sophia to turn to her and turn her head. Sophie leaned in at Sophia's ear, whispering her plan into it as Sophia grinned. "Good ideas sister." She said before turning towards the three women with dicks, winding her tail with Sophie's again.
"You" she started, pointing at the first woman. "Are going to lose your hands. Then you are going to lose your feet before laying on your back. Next your dick will shrink back into you, leaving you gender less. From there your legs will merge into one fleshy blob and your arms will shrink back into you. You will then turn from flesh to slime before leaving this beach for the forest as the new mother slime." Sophia commanded as the woman grunted.
She held her hands out before they started to shrink away, leaving her with no hands as her feet followed suit. Dropping to the ground she grunted as her dick shrink into her, leaving here gender less before her legs merged and her arms shrunk away, leaving her a fleshy blob with a head as her skin turned blue and slimy, her body changing as she slid off away from the beach, leaving a trail of slime.
"Now" Sophia started pointing at the next girl. "You are going to sit down in the sand as your dick moves below you, like a tube sitting in the sand. Your dick will then start to change, becoming longer and more flexible, basically a second mouth. You will now eat from your second mouth and speak from the one on your head. You will also lose your feet and hands, but still walk upright." Sophia commanded as she and Sophie watched her change.
The woman grunted as she sat down, her dick migrating from her front to her back as it started to grow, the tip splitting open as teeth grew into it along with a tounge. Her hands and feet then shrunk into her as she sat in the sand motionless.
"May I change the last one sister?" Sophie asked excited as Sophia nodded. "You can command them as I do Sophie." She said Sophie clapping her hands before turning to the last girl.
"You shall lose your hands and change your arms to wings. Your posture will then shift as you lose your dick and grow a vagina before becoming heavily pregnant with harpy eggs. You will then change your legs to a harpie's legs and grow tail feathers before flying off to a mountain to become queen of the harpies." Sophie said as the woman nodded before grunting.
Her hands disappeared as her arms became blue feathered wings. Her dick shrunk as her belly visibly distended with eggs. Her lower body became feathered as her legs changed as she turned around before flying off to go find a mountain to start her kingdom.
"Soon us monsters shall rule this world. The naga, the slimes, the mermaids, and the harpies. What other monsters shall we create sister?" Sophia asked as Sophie grinned. I have some ideas." She said as she looked at the beach at he humans before rubbing her hands with a grin on her face.
