I wouldn't exactly call these Easter Eggs, they are more like paths I covered which I believe most players will miss but they give cool results.
1. If you finish the Hawatia/Naniri quest without impregnating Zuri (you need only two votes so you don't have to make progress with Zuri and her father), when you play Sumia's Act 2 Zuri is not pregnant and in her sex scenes you actually impregnate her for the first time. Yes, I rendered all those "non pregnant Zuri for act 2" images.
2. In the Limtinia/Kiwanwai quest, if you ravish the orc girl but seduce Tana'Dur you'll get to see how freaky the priestess actually is (nasty dialog).
Consider playing these flows when 0.7 comes
