My little sister has decided to become a gal. When she does become a gal, she has to be flirty, so she decides to practice sex! The partner she has chosen is me, her older brother! I watch adult videos, but I have no experience in actual sex... But when "that day" comes, it will be embarrassing if I don't do it well, and I have my dignity as an older brother, so we practice pistoning together! Maybe because we're related, we get along great! We both inherited our sexual prowess! Even when we don't realize that we've both been cumming and it flows back, we continue our wild pistoning and cum inside each other with massive chases!
