I find you in the living room again being a geek and it dawns on me that you are probably still a virgin. After teasing and making fun of you I finally agree to help you out. As your older sister if you haven't seen a thong before its my job to show you. Same goes for pussy and asshole. You need to know how to pleasure these areas. You need to know what to do when the time comes. I pull my dress up and begin to explain to you everything you will ever need to know about a woman's ass.
