Once she caught her breath, Becca pulled herself back to her feet, and walked over to Sandy. Cum oozed from her tit-pussy, and dribbled whatever was left from her face as well. A look of horror crossed her face as the goth woman came near, but all she could do was cry. There was no place to run.
"I kinda like the nipple pussies, I bet they feel amazing. But that cock on your face? Not so much." With that, she drew again on Jen's mom's face, and her mouth reappeared, the cock and balls dissolving into thin air. "That's better. Now," she said with a pout as if she were talking to a child, "for the real change."
"What are you gonna do!" Sandy shouted as she was suddenly held down by the asian and trans woman, her face to the floor. Heaps of cum and other bodily fluids had begin to cake the area beneath her and now her cheek was covered in semen and pussy juices. Jen for all her mouthless, pussyless self could handle, just watched, still pushing Tanya's neck-penis in and out of Julie's cunt-face.
Jen watched as Becca drew a on her mother's lower back. She heard the squeeky marker against her skin, and suddenly her mom cried out in orgasm. Sandy's new lower penis ejaculated over the floor and up her belly as it was pressed to the ground. With a whisper she handed the marker to Penny. The tattooed trans woman just nodded and made a mark on Becca as well, before handing the marker back to her. Penny started stroking her cock, and the Asian lady Candy bent down and slowly started licking up and down the shaft.
There seemed to be an obvious evil coming from Becca, like her eyes had somehow shifted, like a dark aura surrounded her. She felt like she had absolute power. In her own little world, in this little living room space, perhaps she truly did.
She walked over to Sandy, and touched her lower back, sending her into another convulsion of orgasm. "Okay Sandra, this is it." She bent down and licked the Jen's mom from her ass to her cheeks, even forcing her head further sideways so she could lick across her eyelids, making sure to leave saliva in heavy streaks all across her face. She swallowed, spit onto her eye again, and licked it up, "Your body is delicious Sandra. That's why I want it for myself."
Sandy's eyes went wide as Becca retreated to her ass, and slowly started pulling. It was then Jen realized what was going on. Becca created a zipper! And slowly Becca lifted the zipper upwards, every passing tooth causing ripples down Sandy's body until the zipper was all the way at the crown of her head. Inside there was just nothing. Whatever magic this marker had within it, it could change the very fabric of the universe. Sandy sat there convulsing, spittle building up around her mouth as the pleasure took hold.
Then, Becca did the same for herself. Only this time, she stepped out from her skin, leaving her body fall to the floor. All that came out was an anatomically correct skinless body. Muscles and veins, tendons and ligaments all for the world to see. Even her cock pulled free and dangled there. She approached the other skin suit now, and just before reaching for it, looked to Penny, threw up the devil horns sticking out her tongue, and then dove in.
She stepped into the skin of Jen's mom, the audible sloshing of skin rubbing against muscle and bone was tangible. Soon her entire lower body filled out Sandy's skin, and then she started on the chest and hands. Her own cock slid into the empty skin where Sandy's cock had been. Her tits as well pressed in and stretched out the skin on Sandy's chest. When they settled in place Becca could feel the invasive pressing on her nipples as cavities formed. Now Becca had pussies for nipples, and it felt great.
Jen watched this unfold, unable to say or do anything. Her mom's body taken over in its entirety, by a madwoman. She watched as the final fearful expression crossed her mom's face before Becca pressed herself into the head. Like a vacuum the head suctioned to her face, nose and forehead wrinkling as she tested out her face muscles. A moment later Penny walked behind her, and zipped the zipper down. With a click, the zipper came off, and Becca/Sandra just laughed. Becca was the slightest bit larger than her mom, and it showed, but not enough for anyone to notice. No one except Jen that is.
Becca rushed toward Jen, snatching up her empty skinsuit on the way, and with one swift motion shoved Becca's old face over Jen's face. "Put me on Jen! Put me on!" And Jen complied, shakily pushing her arms and legs into the empty cavernous holes of Becca's old body. Unlike with Sandra however, Becca made sure this one worked differently. Jen gained Becca's mouth, but not the use of her vocal cords.
Additionally, Becca's cock found purchase, invading Jen's lower regions. Also unlike before, Jen's body flared out, taking on the form of the Becca on the outside.
"Oh my god you're gorgeous!" Becca said, holding her own face in her hands. A moment later, and Penny had zipped up Jen as well, locking her into this tattooed gothdoll body. Still holding her face, a darkness fell over Becca/Sandy, and she attacked her hold face with her mouth, kissing it sloppily, feeling around inside at every surface. Every tooth, every part of her old tongue. Despite the horror of it Jen, started getting aroused, armed with Becca's cock she got hard, and Becca noticed. "That much huh? Your own mom!?" She laughed at herself and began to lower herself to the floor, grabbing the throbbing member and slowly pressing it into her right nipple.
"Oh yeah, you like it don't you? Your mom's nipple pussy, your veiny meaty male organ betrays you. Fuck me Jen! Fuck your mother!" Jen thrust in and out on her own, shoving the massive penis all the way inside her mom's body's breast. Her mother's voice came through and even that would not stop her. She was bound to the marker, but even then, she would probably do it anyway. This feeling was so incredible nothing else in the world mattered. "That's right! Fuck my pussy Jen! Fuck your mother. I'm your mother now Jen!"
And Jen came, heavily, into the pussy cavity of her mother's right breast. Becca's breast.
Somewhere deep inside, the real Sandy took a back seat, and watched the whole thing, entirely helpless.
