Castor is one half of Gemini, but this half has a character all its own. The design starts with a realistic-looking head before taking a decidedly more fantastical turn. A beaded chain detail runs down the shaft, with the star and beads creating a striking visual rhythm against the body. The shaft itself follows a gentle curve with a slightly flattened profile, giving Castor its distinctive silhouette. Two rings sit at the centre, breaking up the form with another unexpected detail, while further down, textured wrinkles wrap around the balls to complete the design. As one half of the Gemini constellation, Castor is designed to stand alongside its twin, yet it works perfectly well as an individual fantasy dildo. Familiar elements meet imaginative details throughout the design, creating a piece that feels unmistakably Nothosaur.
