Alastor smiled, nuzzling up against his boyfriend, Lucifer (an omega) He was always quite possessive and territorial of Lucifer, which Lucifer didn't seem to mind.

Alastor had his body wrapped around lucifers, protecting him thoroughly. Usually an alpha would only protect their omega this much if they were in heat, or had a cute little tummy and were expecting. Lucifer was none of those things, Alastor just loved him too much.
