i agree, big brother is supposed to protect the little cute sister, not use her to fulfill the brother's sexual desire, its sick man.
its just how it works in society, yeah yeah everyone think they are 'different' and that if its me its gonna work somehow, but you have to think about those around you too man, life is not just about YOU. how about the future???
come on man you are 21, life sucks but live with it and find other girl to make love with, its not that hard you know.
