Aunty's pussy stretches wide, glistening with desire as she leans in, her breath hot on the niece's ear. 'Look at how big your uncle's cock is,' she whispers, pointing at the thick, veined member. The niece, hesitant, reaches out, tentatively touching it. It jerks at her touch, making her gasp. Her aunt smiles, guiding her hand, showing her how to stroke it, how to make her uncle groan in pleasure.
