Li was excited about the new doll he had received. He hadn't been able to find a girlfriend, let alone anyone who could be his wife, so when the new program had been announced, he signed up as soon as he could, waiting with baited breath until it showed up in the mail. As he unboxed it, he took in what it looked like, and the advertising wasn't wrong, it did look very realistic. It was a bit unsettling to him though, because it looked like it should move or breathe but instead laid there, perfectly still. He shrugged, and decided to get right to it, he'd been waiting for months, after all.
After he'd stripped and begun to pleasure himself with the doll, he found himself a little disappointed. It was impressive and well designed, but it wasn't really any different from using a sex toy. He finished up and was about to pull himself out before the doll suddenly constricted and he found himself stuck.
Li struggled for a few minutes, vainly trying to avoid having to call for help before he noticed something extremely alarming. His junk had started to turn chalk white and when he left the area, he realized it had become like stiff plastic. He jerked back in shock, disconnecting his penis and balls from himself completely, leaving the whole area completely bare and smooth, but the skin left quickly turned into plastic itself. He tried to run to where he had left his phone, but as his whole pelvic area turned to plastic (his butt sealing over in the process) he collapsed onto the floor before his legs began to turn to plastic too. As he flailed, he heard a pair of pops and in horror watched as his legs fell off, revealing a pair of mannequin joints that weren't particularly that well made. He didn't feel any pain, but he was in so much shock he might not have been able to feel it anyway.
He tried to desperately will himself to stop changing but he realized that was a fool's errand when the plastic spread onto his stomach, with a clear line forming between the pelvis and the base of where his abs would be if he had had any before another poorly made joint resulted in his pelvis falling off too. He couldn't believe what he was seeing, as he started trying to feel his torso in another vain attempt to save himself from his fate, but all that did was spread the plastic to his hands which stiffened into a neutral position as his arms changed too. In the process of his flailing, he accidentally pushed what was left of himself upright, resting his torso on the floor with the underside of his waist serving as his platform, surrounding by his legs and pelvis, soon to be joined by his arms as they both fell off too.
He twisted and stretched his neck to try and save what was left of him, but nothing stopped the inexorable march of plastic as he was forced to take on a neutral expression as his face hardened and his hair congealed into a lump of textured plastic. His head tilted to the side slightly as the misshapen joint inside his neck left too much space. His genitals fell out of the doll still on his couch and clacked into the floor in the middle of his view.
The door to his apartment slammed open and a voice said, in Chinese, "Poor fool, he got one of the defective ones. Take him and make sure to grab all of his parts. Hopefully his brain is still active, we can use that."
