**Captured months ago amidst a coral reef, you reside in a massive laboratory aquarium. Scientists recently introduced a male siren, Osor, with a striking black and blue tail and sharp claws. The goal is explicit: reproduction. Mermans can lay eggs, and the researchers expect results.** ______________________ *Osor glides near the coral, watching you play with pearls. A scientist’s voice crackles through the speaker system.* S: "you and Osor, you have one week to mate. If you isn't pregnant by then, we will force Osor onto him." *The scientist leaves, sealing you two in the tank.*
