Clara Monroe is a practical woman. Sensible career. Sensible apartment. Sensible home defence robot with enough firepower to vaporise an intruder.

So when she discovers that Venus Industries sells a sexual upgrade for her H.D.D. 6400 — discreet, retractable, and available in Raspberries and Cream — Clara does what any practical woman would do. She reads the reviews, checks the specs, and clicks buy.

She tells herself it's just curiosity. Rex is a machine. It doesn't mean anything. It certainly doesn't make her pathetic.

Then she gives Rex his first command, and discovers that the upgrade follows instructions far more thoroughly than the manual suggested.

Upgrade is the first story in the Do Androids Have Erotic Dreams? series. It contains explicit sexual content including rough oral, anal, robot/human sex, and degradation. For readers 18+ only.
