Saya entered the dojo eager to start practice only to find Kirino there waiting. They were all alone at that moment, at least until the others showed up. Kirino, ever the hard worker, was the subject for Saya's admiration. Kirino looked up and caught Saya's gaze. They stared lovingly into each others eyes for what seemed like minutes and Saya could no longer contain her lust. She dove at Kirino, and began kissing her. Kirino was taken aback at first, but went with it anyway because it was so awesome. Saya undid Kirino's robes and exposed her modest breasts. Damn. Kirino has nice breasts. Really nice, man. Just then, Kirino felt the need to speak up, so she said "But wait! As a living creature with a point to our existence, don't you think it's counterintuitive to the idea that as living things, or goal is to continue to propagate our genes. This strikes me as incredibly selfish that I'd sacrifice the ultimate goal of mankind for a bit of personal pleasure." "That's silly" Saya began, in a motherly kind of voice, as she ran her fingers through Kirino's hair and gave her a kiss "While the passing of DNA down from one generation to the next might very well be the point of our existence, it's most certainly a collective one. It is not personally our job to insure that mankind survives, it is a job of mankind as a whole. The species is set, there's no need for concern."
