Laurence
"You're bluffing." Dalton said.
"If you want your girlfriend stuck as a MILF, try me." Laurence said.
Stephanie grabbed Dalton's arm and held it tight to contain him. With the conclusion of the second round, the rings started flashing again. Except this time instead of turning into colors, all the rings turned white. The app chimed on everyone's phone.
'Transform or Challenge.'
"Transform or Challenge! What the hell does that mean?" Stephanie said in a panic. All eyes landed on Laurence again.
"Why are you looking at me? I was just as clueless as you guys after round one. I've never seen the game beyond that." Laurence said.
"Why is your ring black?" Ben said, pointing at Laurence's ring.
"I don't know."
"You lying piece of..." Dalton stopped in his tracks.
Everyone else froze as well. Greta's app chimed. Her face unfroze, but the rest of her body remained posed on her back in a sex doll position. Like a robot, Laurence walked over and picked up her phone to show her the screen.
"Transform or Challenge?" Laurence said in a robotic tone.
"What does that mean?" Greta asked.
"Transform or Challenge?" Laurence repeated in a robotic tone.

Greta
Greta didn't know what Challenge was, but she definitely knew what Transform was. And it had already turned her into a living sex doll. She struggled to move her body, but only her mouth and eyes were mobile. How was she supposed to do anything frozen like a doll?
"Challenge." Greta said.
Laurence clicked the button and the app screen changed.
"Your challenge is to guess who is fucking you. Guess correctly four times and return to normal. Get one wrong and your transformation is conditionally permanent." Laurence read off the app. He followed up by making a makeshift blindfold from a discarded shirt, ensuring that Greta couldn't see at all.
Greta's view was blocked so she had to rely on her other senses to get her through the challenge. Although the idea of turning into a sex doll was hot as a fantasy, she didn't want to be one permanently.
The first cock entered Greta and began fucking her. It felt good. Too good. Each thrust was distracting her from the goal of the challenge. Because she was a fuck doll, her whole purpose was to be used. And when someone was using her, the euphoria was unmatched by anything that she had previously experienced.
Through the haze of pleasure, her mind focused on the cock. It was so big that it could only be one person in the group.
"Ben." Greta said.
"Correct." Laurence said.
The euphoric feeling disappeared abruptly as the cock was withdrawn. Within seconds, a new sensation penetrated her. It wasn't the size or girth of the cock that gave her a hint of its owner, but the way that the person moved. It was timid. It was gentle. It was safe. There's only one person who it could be from the group.
"Laurence." Greta yelled.
"Correct." Laurence said as he hovered over her.
And like the first cock, the second one disappeared, albeit with a less noticeable change in pleasure. So far, she had two easy lay-ups for cocks, but the next two were going to be difficult. With no time to spare, the third cock entered her pussy. It was someone who knew what they were doing. The feeling was vaguely familiar. Without being able to lift her arms and feel the rest of the body to confirm her suspicions, the only thing that Greta could do was guess. Between Mark and Dalton, if both cocks were roughly the same size, it had to be Mark. Dalton was a brute, and his thrusts would be much more aggressive to assert his dominance.
"Mark." Greta said confidently between thrusts.
"Incorrect." Laurence said.
What! How could that be? There was no way that the gentle fucking was the big bully. Laurence removed the blindfold and revealed a familiar face. Her lover. Sally, who was now a robot. She was wearing the strap on that they had brought for later in the evening when they were alone. The reason Greta couldn't tell it was Sally was because Sally's movements were still robotic. The fucking had been familiar, but not too familiar. Because the dildo that they owned was as realistic as possible, it had been impossible to distinguish it from a real cock.
Sally exited her partner and stepped back. Greta's body felt light, like her limbs were full of air. Her arms and legs were spread out and open, welcoming anyone who wanted to use her. The hollow feeling extended through her breasts, leaving the feeling of balloons on her chest, and then worked its way up through her throat and into her head.
"Noooo." Her scream was silenced.
Greta's gaping mouth froze open in a large 'O', big enough for any cock to fit. She felt like a feather; light and empty. The horror of turning into a sex doll faded and her thoughts turned to cock. All she wanted was cock in every hole. She needed cock in every hole. It was her purpose now. She desperately wanted to satisfy anyone that used her.
Her ring color faded, leaving just a normal ring on a sex doll. Another sex toy for men to use. That was her new purpose in life.

Stephanie
Everyone unfroze. Despite having been turned into a MILF, Stephanie couldn't believe the sight before her. They were all aware of Greta's challenge and stood in awe of the result. Greta looked normal, but upon closer inspection, her body had the weight of an artificial sex doll and her eyes were blank and devoid of the usual liveliness the lesbian brought to parties.
"She's an actual sex doll." Stephanie said. "It turned her into a sex toy!"
Elizabeth, now Lizzie the bimbo, laughed, like she did at everything. Sally stood stiff and unmoving but was presumably internally upset. Tiffany was still posing as a mannequin. The rest of the group panicked and turned their attention back to Laurence. Dalton didn't hold back as he grabbed Laurence and punched him in the mouth.
"You fix this you little creep." Dalton said. "You knew exactly what you were doing when you signed us up for this."
Laurence wiped the blood from his lip and laughed as he stood up. "You all agreed to it. Now you're going to have to finish the game."
Dalton went for another punch but froze with his fist inches from Laurence's face. Everyone else froze too, except Stephanie. Her phone chimed, directing her attention to the app.
The two options appeared. Transform or Challenge. She had just watched Greta turn into a sex doll after failing her challenge. But what was transforming? Was it bypassing the challenge, and accepting the existing changes? That meant she would be a MILF permanently. If there was a way to beat the game and revert to normal, then she had to risk the challenge. By choosing transform, she was letting the game decide and so far the game did not have the best track record, especially for the women contestants.
Stephanie selected Challenge and begrudgingly read the challenge that appeared.
'Your challenge is to make sandwiches for all the men and to bring them sandwiches and beer while being pleasured by toys. If you orgasm or fail to serve your men their meal before time runs out, your transformation is conditionally permanent.'
What kind of challenge was that? It sounded like something...that a housewife would do. The thought sent a nervous chill down Stephanie's spine. It didn't take a genius to figure out what her transformation would be if she failed and that's why it was critical that she completed the challenge.
Before the timer started, a mindless Elizabeth walked over with sex toys in her hands. Momentarily, Stephanie froze, giving Elizabeth access to her pussy and ass. Elizabeth showed Stephanie the large, lubed up butt plug and then bent Stephanie over. Her rival worked the plug into Stephanie's ass and its presence was noticeable with the slightest movement. When Elizabeth stood her back up, Stephanie's asshole tightened around the plug, giving her a taste of the obstacle that she would be dealing with during her challenge. Elizabeth finished her duties by placing a vibrating egg into Stephanie's pussy and setting it on high. Once the toys were inserted, Elizabeth moved back to her original spot and froze again.
