Shane Daniels has wanted Valentine for years but as his best friend's little sister, she's strictly off-limits. But when Valentine talks him into giving her D/s lessons, he gives in to some of his darker urges and dominates her sexually.

Now they are locked in a battle of wills as Valentine pushes him for a consummation of their new relationship while Shane tries to keep himself from taking her completely. Who will win? They'll both find out when Valentine takes her spanking.
