Mirror of Desire by Redneck Rubber (Archive Link)
This is another fantastic latex sex-doll transformation story by Redneck Rubber. The story follows James right after he was dumped by his now ex-girlfriend for his rather kinky desires. She wanted nothing to do with that and just before she stormed out of his flat she told him, she’d set him up with someone just like him. Following that, James discovers some kind of mirror with the label «Mirror of your Desire». Still quite bummed out, James begins drinking and makes some jokes in the direction of the mirror, but after passing out and waking up again, he discovers some severe changes were happening to him. Black rubber was spreading all over his body, as it began to transform into a far more feminine form, and soon James finds himself looking like his absolute dream rubber partner. Tiny waist, large breasts and a body completely made out of red and black rubber. And nothing seemed to be removable, as the seams for the shoes or the corset were barely even visible.
James, now Jamie, soon finds out what exactly had happened to him and what his ex-girlfriend actually meant with her last statement…
