Iirc the egg is a part of a test to prove that Kouchi is a suitable bride. Because the haters were saying Cauis abandoned his people and now he wants a drawf wife after he turned down a hot Titan bride. So his siblings who are secretly on his side suggested a test to prove that Kouchi is worthy and by extension Cauis is worthy to be king again. But haters gonna hate ig. And sometimes try to murder you.

I forgot why they needed to hatch the egg. Was it to prove that Koichi had enough magic ability to take titan dick up his ass without pain? Even if it can help with pain, are his organs gonna be intact? Imagine having such a good time on the big rod that you don’t notice your intestines getting ground up
