The last thing I want to do is talk to my virgin little brother about sex, but once I start describing foreplay, initiating sex with a woman, and demonstrating it on myself, softly and sensually touching my own body, I start to get aroused. I am awkward and embarrassed but decide to go with it, explaining the female cycle, ovulation, and the different types of feminine wetness, until I get so horny that I decide to show my pussy, showing where the clit is, showing off my lips, and talking about the importance of lubrication. One thing leads to another and I need to penetrate myself, locating my hairbrush, first rubbing it all over my wet pussy, and then fucking myself until the cream runs out of my pussy, down my butt plug and I cum in front of my little brother! So taboo, I hope you enjoy this lesson from your older sister.
