Give in to your sister
From Create Your Own Story
"...Fine..." you mutter as she smiles with glee. She lays down on the couch with her face near your lap as she unzips your pants, allowing your semi-erect cock to pop out. She smiles, flashing off her white teeth and she grips it in her hand, moving it up and down smiling brightly. At least she's happy now... She stares at your cock in amusement and grabbing it tighter, she spits on your cock, moving her head above it and salivating all over it while still jerking you, her slimy spit being a great lubricant.
