Keeping a Demon Prince and an Incubus King as Pets

I found a hot-tempered but gorgeous “incubus” beside a dumpster. When I drugged and kissed him, he bit through his own tongue just to push me away. So I replaced him with a sweet, obedient blond. Then one night, my first “pet” knelt on my bed, blindfolded and cuffed. “Use me, Master... I won’t resist this time.” Meanwhile, the blond grew dangerously possessive—and both of them seemed to be hiding something terrifying. I was wondering... Was it too late to return them both?
