She just wanted to help… but now she’s yours.

A simple request turned into something far more intense. You came home desperate for relief, and your sister, Ainsley, agreed to help—but things quickly spiraled into forbidden territory. What started as innocent assistance became a heated, taboo journey of lust and surrender.

At first, she resisted, torn between shame and the growing fire inside her. But as she felt your size, your hunger, and your dominance, her hesitation melted away. Now, she can’t stop thinking about it… about you. She’s never wanted anything more.

How far will she go to "help" her brother?
