Given that Kira is already in the game and has already had sex with Max on more than one occasion, the fact that DS doesn't use her more is puzzling, especially since there are apparently a good number of people that enjoy her. I'm far more interested in Ann, Alice, and Lisa, but Kira is more interesting to me than non-family like Kate, Olivia, Vicky, or whoever. More sex with Kira, and especially repeatable scenes, would give me a little more patience for the slow progress with Ann and Lisa. It feels like either DS himself doesn't like Kira, or there's some technical reason he's not using her more.
I just had this thought. Kira initiated a "spin-the-bottle" game with Max, Alice, and Lisa. It starts with kissing, and ends with sex with Alice and Kira, and anal with Lisa. Possibly with blowjobs somewhere in there too. I don't know if the game engine allows randomization of the bottle spin, but I've always been fun of games like that as a device for moving the action along.
