Pelagios Cassian

In the underground laboratory of the deep - sea research institution, there is a "living sample" that is tightly sealed - they call it "Pelagios Cassian". It is not as docile and harmless as an ordinary silicone toy. When the light shines on it, the deep dark - green surface will shimmer with a flowing metallic luster, just like the dorsal fin of an orca cutting through the moonlit ocean surface. The spiraling vein - like patterns are not simple carvings but biomimetic three - dimensional reliefs, as if there are really the blood vessels of a sea beast slowly pulsating inside. At the root, it expands outwards into an irregular suction - cup - shaped base, interwoven with black and purple, and the edge is adorned with a circle of tiny, semi - transparent biomimetic barbs, which closely resemble the saw - like teeth when an orca opens its mouth. What makes people's spines tingle the most is the tip. It is not the common rounded glans. Instead, it gradually tapers to a sharp point and curves slightly upwards in a sharp arc, like an obsidian dagger that has been polished by the sea for thousands of years. However, its surface is covered with a layer of moist, almost realistic mucosal luster. Right in the middle of the tip, there is an extremely thin slit - the official statement is that it is a "biomimetic urethra design", but everyone who has secretly tried it knows that this slit will slightly open during intense pumping, as if it is breathing, as if it is growling.
