Summary
Nico is a Death Angel and Percy is a Dog Demon. But Nico thinks Percy is a regular puppy, a stray he took in months ago. At least until Percy hits his first heat and reveals his true form to Nico. The dominant Death Angel can hardly deny the call of the submissive Dog Demon. Not much plot, I just wanted creature-smut. Nico/Percy slash mpreg Nicercy
