I don't know if my Sims are either pretty or sexy, but I do know they are CC-free. So I'll show you some of the singles I have on the Gallery.

I do have many more Sims on the Gallery, this is just a selection. Feel free to check out
my Simblr for more Sims, information and extended backstories.
Also, you might want to have a look at my
Male CAS Challenge thread - see if you can find some inspiration there.
And in terms of aliens, I do have an alien family:

I do also have a female alien, but she's not on the Gallery. I can upload her if you want though.
