Joining an alien family!

Humanity has found extra terrestrial life and it seems to be alot hornier then we ever thought! The scenario here is the following, I've married an alien MILF and now I have to meet the rest of her family and adjust to the very open sexuality of her culture. The pics above should be a good example of what I'm talking about.

I'm open to ideas and while this is mostly smut based, I do enjoy plot and story to be mixed in. Kink wise im also pretty open, the kinkier the better. Maybe I need to impress my mother in law or have some bonding time with my alien femboy step-son. Fell free to do or ask whatever you want.
