When Kira is in the lounge at 3AM you go to her and watch her until you see the "Aunt Kira" option to interrupt her. (Otherwise you'd keep watching her and eventually join her for a BJ as she uses the dildo saddle.) After the next question from her you should then see an option to watch TV or movies or practice kissing.So aunt kira mentions she'll teach about kissing when she's watching tv at night, but she never does.
