Jeff decided to give them both another fetish. He scrolled through the Chronivac, looking for a good option. As Sarah watched her boyfriend browse the device, something warm and mushy filled the back of her diaper. She blushed, excusing herself to go to the bathroom.
Jeff found an option labelled 'amputee'. He decided to choose that one, and hit apply. Suddenly, he began to think of his diapered girlfriend with no limbs, her being completely dependent on him. His tiny cock became hard, and he moved to get rid of his girlfriend's limbs, but after a moment of thought, he decided to just get rid of her arms to start.
Jeff heard a scream from the bathroom. He ran to the source of the noise, and found his girlfriend on her knees in the bathroom, with no arms. Sarah looked up at Jeff.
'Did you do this?' She asked.
'Yes,' Jeff answered. 'Do you like it?'
'I...' She paused. 'I love it.' Jeff was happy to hear that, and helped his still diapered girlfriend back to the bedroom. She lay on her back on the bed, and Jeff took off her diaper. She was soaking wet.
'Jeff, please,' she said, clearly horny. Jeff started to rub her pussy, eliciting a moan from Sarah. He fingered her vagina until she came, peeing everywhere as her slit spasmed.
'Jeff, take my legs too,' she said, as Jeff smiled and moved to the Chronivac, removing the rest of his girlfriend's limbs. Sarah excitedly watched her legs shrink back into her body, leaving nothing but two stumps beside her moist pussy. She had nothing but a head and torso now, and she would be completely dependent on Jeff. She was just his diapered fuck nugget now, and she loved it.
Jeff used the Chronivac to grow his cock again, making it 10 inches long. He inserted his cock into her pussy, making her stomach bulge. She screamed with pleasure, not able to move. Jeff filled his diaper again, as he thrust powerfully into his girlfriend's pussy.
Eventually, they both came, leaving a mess everywhere. Jeff shrunk his cock again so it would fit into his diaper like before. Sarah had no choice but to lay on the couch, watching her boyfriend on the Chronivac. She was loving her lack of limbs, and being dependent on her boyfriend.
