Well then you can give the short visual novel with a nudist beach theme a try involving naked women and if it includes naked men in it as well , i will accept but only if it includes gender option
and also you can make a game set in space similar to Voices In Space but with only girls a try especially when they are only naked without clothing in a space station when they do sex along with the part where they do lesbian naked sex in a forest planet,give them a shot
