Chuuya looked down at the crate, a shipment of omega’s had been intercepted before they could be sold under the port mafias nose and this crate contained the last omega.

Chuuya had wanted to keep this last one as a little prize for having saved over 1000+ omegas from being trafficked. The cage was covered with a blanket and he was standing far enough away, looking down at it. “Omega..” He purred.
