My sister walks into the room and sits next to me and I can instantly spot that she looks a little more dressed up than usual. (She's nicked one of my dresses and everything!!) After a little bit of probing she confesses that she has a date tonight, but I know my big sister and lets just say that *I'm* the more experienced one! She really needs my help if she's going to keep him interested and so I tell her she really needs to practice her kissing. With her date being tonight and nobody else around, the only option is me, her sister! I show her exactly how to do it and we practice our kissing on each other. - This will be our little secret!
