He looks supprzed, "of course not, I love you! I was afraid that you would leave me in two months, so I had to do something to keep us together... I'm sorry for not asking you first... will you forgive me?"
You do the space lizard equivalent of tearing up, "of course I forgive you! I love you human! Skrew the mission you picked me up for, I want to raise these eggs with you!"
You and your new husband hug and kiss and have all sorts of fantastical sex. Eventuality the egg hatches and you become a happy, if odd, family. You have three lizard triplets, a girl, a boy and the last seemed to be some sort of hermaphrodite, but you loved them all. The girl you named Nora, the boy Brian and the herm Quinn.
They seemed to take after their parents, you found then having some sort of incestuous orgy. Brian was fucking Quinn in her vagina from behind, while Quinn was balls deep on top of Nora's vagina. The loud moaning could be heard light years away. Clearly they were all, or were, vergins. Seeing them disgusted you, but it also tuned you on on some level. Hay, they were of legal age at least.
