In the Dark: An Erotic Short Story

An erotic short story with bondage/restraint, master, slave, spanking and lesbian themes.

She has been left alone, blindfolded, near naked and tied to the bed, while her boyfriend goes out to buy something to use on her. Above the silence she hears the creaking of floorboards outside her room, then the unmistakeable sound of her door swinging open, telling her she is no longer alone. Is it her boyfriend sneaking back, or maybe one of her female housemates? Maybe it is an unknown intruder. Whoever it is, they will see the excitement darkening her knickers and know she is completely at their mercy...
