"Heh..." She rolled on the couch, her head now hanging off the side, her hand reaching for his dick. She brought it close to her lips, just catching it's warmth and scent. "You have a nice dick little brother. It's really a shame that I'm you're sister." She said in a weird voice. "Anyway..." Her hand started to stroke him quickly right from the get-go. She brought his tip close to her lips and smiled again. "It's okay, you can cum. Your dick's slightly out of proportion with your body... but it's hard as stone. It smells good too... Would you rather me use my tongue, or my boobs? Or do you just want me to milk you like the little horny goat you are...?" She leaned closer to his cock and spit on it, just to keep it from becoming dry.
