Outbride: Beauty and the Beasts Vol. 5 (manga)

In this isekai romance, a young woman named Mashiro is reborn in a fantasy world inhabited only by men–and suddenly finds herself with four supernatural suitors! These handsome men with fur, feathers, and horns call themselves gods. She’s now the sole human female in their world, so they all want her to bear their children. As if that’s not enough, the air of this new realm is permeated with a poison that only a god can suppress…with a kiss.
