In the dim light of their shared room, the sisters let their inhibitions drop. One lies back, her legs spread wide, as the other leans down, her tongue tracing the outline of her sister's vagina. She flicks her tongue against her clit, making her sister squirm. Then she slides a finger inside, feeling the warmth and wetness. Her sister responds in kind, their moans filling the room as they explore each other's bodies, their fingers and tongues finding new ways to please.
