Sarah scrolled through the list of fetishes until she found one that read 'penis shrinking'. She laughed, imagining Jeff with a tiny penis. She gave him the fetish and hit apply. Suddenly, Jeff walked into the room. She could see the outline of his cock in his pants; he had a decently sized penis, which never failed to make her orgasm. But she knew that would soon change.
'Babe, could you make my cock smaller?' Jeff asked. Sarah obliged, using the Chronivac to shrink his manhood. She hit apply, and took his hardening cock into her mouth. She always loved blowing him; the feeling of his warm cock in her throat, and now that she knew this would be the last time for a while, she really savored it. She sucked his cock as if it was giving her life, making it hard for Jeff to stand. He moaned as his cock slowly shrunk, filling less and less of Sarah's throat as time passed.
Soon after, his cock barely reached her tongue as he came into her mouth, Sarah swallowing it all. She took her lips off of his cock, gazing at the finished product. His penis could not have been more than an inch long now, and his balls were tiny too; only the size of blueberries. Jeff blushed as his girlfriend looked at his shrunken cock.
'It's so cute!' Sarah said, resting his new baby dick in her palm.
'Is it hard?' She asked; Jeff nodded, causing her to cover her mouth and giggle.
'Well you're not gonna be fucking me with this,' she said. 'Lie down.' Jeff obeyed, laying on the bed with his tiny cock exposed. Sarah began to rub her foot on his cock, making him moan. In less than a minute, he climaxed, covering Sarah's foot with cum.
'You came so quickly!' she giggled. 'Now clean it up, Jeff.' She moved her foot to his mouth, and Jeff wasted no time, licking her feet clean of his cum. He sucked her toes, making sure that they were clean.
Jeff and Sarah sat on the bed, Jeff's chest and face covered in his cum. He loved his new tiny cock. As he lay there, he began to wonder what they should change next.
