Sokka and Katara
Before meeting Aang there were not numerous things to do for Sokka and Katara. To get food and to stay warm and no entertainments at all. Well, except for one - whenever Sokka gets hard! And believe us, he gets tough fairly usually! As an excellent gal Katara aids Sokka to deal with his boners in one or an additional means. And that's the thing: the more usually she does it - the more she likes it herself!
