"But first I'll change a little thing~" Hilda said using her powers on herself, to combine her two faces to turn into her original one, "this feels better for now" she regained all the traits of her split personalities, but when she decided to divide her body in two it would be split in her and Hillary back. She also kept the four arms while she was in her united form.
"Now what was I about to do... Ah yes! My two precious women~" Hilda looked at Amanda, "my beautiful mom" then her sight turned to Jane, which even that she was removed from the merged body and was supposed to go back to her original form she still was a woman, and a mature one, "aaaand my sister, or should I say aunt? God this is so confusing, but it won't matter anymore~"
"What are you doing dear!? I order you to free us now!" Amanda said blushing and naked, incapable of moving.
"Or what?" Hilda laughed, "as you see, I'm in charge now! You will pay all the suffer you made me go through as an ass tit constantly farting cum!" She raised her four arms while leaking milk from her anus-looking nipples. And "I have a magnificent plan for you two~" she began to manifest her powers she just obtained from the computer.
"No! Stop!" Jane watched Hilda to point two of her arms at thier mother. "What will you do to her!?"
"There's a couple of things I wanted to experience with this, one of them was... Having a cock! Which you two already experienced but now is my fun time~" Hilda said making Amanda float to her, attracting her with her fingers, making her mom's head approach her crotch.
"No sweetheart sto- hmmph MMMPH!!" Amanda couldn't keep talking as her head was deeply pushed to her daughter's crotch above Samantha, which was just spectating everything and drooling from her mouth as Hilda was extremely horny and excited. Amanda's face began to melt as Hilda's crotch assimilated her. Her head was completely swallowed turning her hair into Hilda's Pubic hairs, begining to morph the rest of her body, her arms and legs shrunk and melted with her torso to grow larger, her butt sealed to just leave her pussy alone. She turned into a long flesh tube attached to Hilda, her body began to alternate again to look more like a cock, and change her insides, turning all of them into a long tube connecting to a sack of testicles that grew inside Hilda to produce cum, at the same time the same tube connected to Hilda's bladder, Amanda was done as a penis and her pussy was Hilda's cock urethra.
Hilda grabbed her 10 inches long new asset with two of her whole hands to massage her massive trunk, she made it so it could easily bend in any way so she could insert it inside Samantha, testing her experiment immediately. Samantha gladly opened her mouth to swallow the giant pussy-cock that was her new neighbour, swallowing all of it, while Hilda moaned and yelled feeling something she couldn't describe but was the most incredible sensation she experienced. After a couple of seconds she stopped fucking herself to focus on Jane.
"Don't think I forgot abou you~" Hilda said approaching Jane, looking like she almost had a third leg hanging between her other two.
Jane sweated. "What? Now I'll be your pussy again?"
"No, but a close one! I enjoyed our sibling bond as pussy and owner but I'll make something greater~ You see, mom already experienced how pregnancy feels with you and me, so I want to experience that too, but with my sister~ or aunt... I don't care"
"What do you mean!? Isn't that your nasty pussy's job?"
"Hey have more respect for Amanda! She is my vagina, but you'll be where babies are born, my womb~ So you'll function as my cum storage and baby maker!"
Hilda used her powers again to attract Jane to her, Jane tried to move and struggle but it was useless. Hilda decided to lay on the bed while Jane had her immobile body laying face down floating above her, slowly descending to Hilda's belly. As like the others, Jane began to go through Hilda's belly, her arms and limbs shrunk like her mother's transformation, until she was fully absorbed by the belly. Now inside of Hilda, Jane's entire body turned smaller, floating around Hilda's organs until she saw the womb, quickly being absorbed by it and turning all of her existence in an internal sack attached to a pair of ovaries and Samantha's mouth. Jane finished transforming into a womb, capable of doing nothing more than what Hilda said, accumulate cum and produce babies, also having to endure Hilda's period cramps every month she wasn't pregnant.
Hilda rubbed her belly with her two upper hands while stroked her cock with the others, "Good girls, I thought being pregnant at 19 was too early but this whole mature body awakened my motherly instincts~" she giggled, now using her upper hands to masturbate her anus tits, "and you'll help me to feed them too dad~ this is a complete family reunion". Hilda stood up after playing with herself, "let's get the job done~" she masturbated her cock until she reached the climax, quickly shoving it inside Samantha's vaginal mouth, Amanda could feel how the cum came from her pussy acting like the tip of a dick, filling Jane's insides as a womb.
Hilda smiled feeling her insides being filled by her own cum, so much cum that some of the drops of it leaked from Amanda's mouth holding the massive penis inside her, Hilda loved so much the feeling that decided to stay like that, just stealing a pair of her mom's sexy black panties and putting them on, seeing how funny the big bulge of her own cock inside of herself looked.
"We're done for now, I hope you will behave pretty well in your new positions~" Hilda giggled again walking and sensing the pleasure of fucking herself, feeling thousands of times better than inserting toys inside of Samantha, she let out another fart to make Layla expel it through her mouth even if she enjoyed it, she decided to go to the bathroom later. Meanwhile Amanda and Jane suffered the torture of their daughter/sister/niece one filling the other, entirely at the mercy of Hilda's twisted desires.
