As a good uncle, I like to leave my niece's pussy nice and full since she lives with me.

Every night, I sneak into her room, waking her up with my big dick. She's a skinny teen, but she loves it doggystyle. I make sure she's riding me hard, feeling every inch. She moans softly, not wanting to wake anyone else. We keep our secret, enjoying each other's company. She's my hot chick, and I'm her uncle with benefits.
