Megan knows exactly what she wants for her birthday. The present is not an object, but the act with the object. Her boyfriend, Sam, has always been compliant with her kinky requests before, but this act went far beyond a pair of handcuffs and light domination. He would have to open up to her in a way he'd never done before.
With the special object bought and the birthday meal completed, she presents it to him and all he had to do was accept it, in more than one way.
