You and Liam were centaurs, centaur-cows he were a bull and you were cow, both of you were male but you were born as cow.

(If you don't know how centaur looks like they human with instead of legs they have horse body with four legs, belly, and tail, centaur has two stomachs, but if they get pregnant, The fetus will be located in the animal's like stomach.)

You love each other and are mates. You two don't live like others on farm yet you live in den like wild horses, yes centaurs are you friends.

It was Spring, the mating season both for horses and cows, and your Liam weren't careful while mating. Now four months later it was August you were pregnant carrying four young ones.

You were laying in your den which was cave, with soft stuff, pillows, plushies, and others stuff you needed.

And there is small problem that neither you neither him doesn't know that you're pregnant.
