Sexy Sibling Poll (Patreon)

I'm getting back into it, but my inspiration is kinda fickle. I have an idea for a joke about sexual-tension between step-siblings, and I just need it to be a cute, wholesome, boring family adopting a couple sexy troublemakers who fuck the whole family. Should it be:

An Elf family adopts a couple sexy Orcs. The boy will have a huge green cock, and the girl will be an insatiable sex-shaman. 

An Angel family adopts a couple of Demons. The Angels think they can redeem the Demons, but the Demons fight back by being extra slutty and horny. 

A Human family adopts a couple of Anthros. Specifically a Catgirl and Dogboy pair of twins.
