Its your birthday and I threw you a surprise birthday party. The last of your friends were just picked up by their parents. Our parents still aren't home...its time for me to give you an extra special birthday present. I know you miss your big sister so much because I've been away at art school. I've been missing so much. And I know our parents are dorks...they haven't been teaching you what you need to know about growing up. Have you had sex yet? No? What about masturbation? You know...when you touch your private areas and it gets hard and then shoots out white stuff? You've been doing that? Good...I want to help you cum right now. I want to help teach you the way to have a good orgasm. Its the least I can do as your big sister. And its your birthday...the birthday boy deserves to feel good. I talk sexy to you and coach you through masturbating while undressing and getting sexually aroused. Its so fun watching my little brother's penis get hard and excited. You can't tell anyone about this though, they wouldn't understand. People will say this is wrong. Its not. But people don't get it. We love each other, this is okay. This is what people do when they love each other. Its so fun watching you finally cum at my word...maybe one day we can have sex! ;)
