Your sister comes in from partying at a rave with her friends. You find her set up in her room with a little light show of her own going on, and let's just say she's still feeling a little ecstatic. She tells you that she wants to play a little game, where she tells you what to do, and you have to do it. She teases you with her little booty shorts and then tells you to take out your cock. She can't fuck you or touch you, that'd be too taboo, so she will tell you how to touch yourself. She takes her top off, playing with her big, soft tits as she gives you jerk off instructions. Don't you want to cum for your sister?
