Nice catch... Believe it or not, I did this on purpose, and here is why. Kissing is something you do when you're in love. Sex is something you can do with any old prostitute. At this point in the game, the characters are trying to justify their actions to themselves by convincing themselves that they are acting on their baser desires of lust. Kissing would be admitting that you're not just fucking your brother, but that you love him romantically as well. As the characters relationships develop more, they begin to accept their own feelings, and kissing will come into the game. As a matter of fact, the first kissing scene will be in the very soon to be released 0.07 update.But i noticed something in that game that just let me in with a weird feeling, not a single kiss, even a peck on the lips. I noticed this because i just had a scene with two girls during a dare game where one had to kiss the other, but even this time their faces were hidden by an arm!!
Weird !!! you find any kind of sex in that game, oral, anal, vaginal, but mouth to mouth seems to be the ultimate tabou, you can fuck your sister, but kissing her is out of question, maybe a bad breath syndrome in the family gene pool???
