Knocked Up By The Orc by Sara Goodhead

She signed up for a baby. She never expected to fall for the monster.

June Marlow is twenty-six, a vet tech with steady hands and zero patience left for dating apps. She wants a child, and she wants it honestly, so she signs the Mating Program's pregnancy-track trial and gets matched with Korag: seven feet of gray-green Stone Tusk orc, a stone-countertop installer with careful hands, a formal mouth, and a knot he warns her about up front.

One trial weekend. His apartment. Walk away free at any point.

But Korag cooks her dinner, builds his own bed, and looks at her like she is a person first and a promise second. And when she invites him to stay, when she asks for the knot night, all of it, he gives her everything: pinned to the wall on nothing but him, ridden out slow in his chair, and a vow spoken plain in the dark.

A scorching monster mating short with knotting, size difference, a possessive-but-tender orc, and a pregnancy HEA that is celebrated, never sprung. Standalone with no cliffhanger. No cheating, no other woman, no games, just a beast who cherishes and a woman brave enough to take all of him.
