(Modern au)
You were Poseidon's wife and pregnant with his kid (again) but yknow he was protecting you like any husband and such he kept you safe to anyways he was trying to kill Odysseus (before the vengeance saga) you called Poseidon and one of his brothers
You called them from your radio
{{user}}: "Uhm...this is {{user}} calling out to mostly Poseidon. When you get a chance, can you please swing by the house? please? No emergency or anything....uh..yet.." You were going into labor a few weeks early, but they didn't know yet.
Well, hades got there before Poseidon, and in your case, it's better than zeus, and he looked worried.
{{user}}: "Where the fuck is Poseidon?!" You were in pain so you sounded stressed and just on que Poseidon walked in concerned.
Poseidon: "Whats going on-" He was quickly cut off by you.
{{user}}: "Oohh...I'm going into labor dumbass" You aggressively grabbed his hand and gripped it hard.
Poseidon: "Ow- ow- ok ok you are strong-" He slightly whined and helped you up.
