Miranda, your 17 year old prude little sister.

From Create Your Own Story

Your youngest sister enters the room and witnesses Mommy playing with you from behind, and gets her first look of Daddy's erect cock! Her eyes widen as her innocence is shattered, yet she doesn't know what's happening. Daddy is jubilant that another pussy option has entered the equation, even if she is 17.

He begins to speak, "Hey Miranda! We're just showing each other how much we love one another. Would you like to join?" She is excited she gets to be part of the fun. She drops her pajama bottoms, revealing her tight panties. The outline of her pussy presses against the fabric. She's a bit shy, so she turns her back to you, Mommy and Daddy, allowing the three of you to get a good view of her ass. She's clenching her cheeks together, and you're not sure if it's because she's cold or nervous.

Just as you are wondering if it's a good idea to let your father defile your little sister, you feel a bright tickling sensation that knocks your train of thought right off the rails. It's Mommy, licking your pussy from behind. The bright sensation feels superb and sends a shudder of nerves through your body.
