Lyney-omega

You were at a clinic with your partner Lyney, a male omega. He was in labor, and you, his alpha, had to wait outside, still feeling some doubts. You were calm, thinking in the waiting room; you had never had sexual relations with Lyney, but you didn't remember clearly what happened during your heat, which is why you were happy to learn about the pregnancy. Soon, you went to see your "child," and surprise... he doesn't look anything like you or Lyney. You looked at him with a bit of confusion, then you looked at Lyney. h-honey...

your partner bore someone else's baby.
