Dairy Production Assistant by Threk
This is another fantastic unbirth story by threk following Shyla beginning her work on a cow-girl ranch as a LIPPS, Lactation-Inducing Pseudo-Pregnancy Substitute. As one might expect from the name, it implies being a substitute for an actual baby, so the cow-girls bodies remain in a semi-pregnant state and continue to produce the massive amounts of milk during that time. During her introduction, she sees the different parts of the entire system, especially the ways the farmers differentiate between actual pregnant cow-girls and those carrying a LIPPS. Another thing that gets Shyla quite excited are the toys that she, as well as her soon-to-be host Tilda get to use to “further” the milk-production. Notes / summary for me (SPOILERS!) Especially the ways the identifications for the LIPPS-cow-girls get lost is quite nice, with Shyla unknowngly getting forgotten more and more during that time. Also the fact, that there isn’t actually a visible difference between a pregnant cow-girl and one with a LIPPS, makes the entire thing even better, as there isn’t any indication of the person trapped within. ...
A Place to Crash by Redneck Rubber
A Place to Crash by Redneck Rubber (Archive Link) In this latex sex-doll transformation story by Redneck Rubber, Karen crashes at Julie’s place. Julie, always ready to help Karen, offers her her sofa and a blanket, also telling her that she’d be away the next morning for a few hours. Waking up the morning after, Karen finds Julie gone and begins walking around her flat a bit. She soon finds some kind of sex-doll with a giant black dildo as a penis on Julie’s bed, and with curiosity getting the better of her, Karen starts pleasuring herself with the doll. Not minding the black cum-like liquid that the doll had begun pumping in her, Karen couldn’t believe how good it felt and when Julie finally comes back and discovers that Karen had used her doll, she begins explaining where it came from and what Karen got to experience following her time with the doll. The one strong warning Julie gives her, though, is that the doll should under no circumstances cum inside her again, as otherwise the changes to Karen’s body would become permanent. ...
Mirror of Desire by Redneck Rubber
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. ...
