At a little after twelve, she finally got up for a late-night snack; perhaps a little food in her belly would help her think about something besides cock, so she could sleep. Katy started to put on a nightgown for her trip to the kitchen, but decided against it. Her parents and brother would be asleep by now. There was no reason not to go naked.

Her big tits swung and jiggled as she trotted downstairs, the nipples as stiff as thimbles. Katy was just about to go into the kitchen when she heard a noise behind her. It came from her parents' room down the hall.

There were always strange sounds late at night, from cats or passing cars or even the wind. But this one had been different somehow. Katy immediately padded barefoot down the short hall, staring curiously at the door of her parents' bedroom.

The door was ajar. As she approached, Katy heard another sound, a soft, drawn-out groaning. Then she knew instinctively that she was about to see her parents fucking.

She hesitated, as a deep need penetrated the innermost depths of her cunt. The sounds continued, louder now; her mother squealed and whimpered, and the bed creaked as her father fed his prick into her wet cunt.

Katy's pussy lips squished greasily together as she took the last steps to the bedroom door. Pressing herself against the hallway wall, she looked through the opening into their room.

She could see their bed perfectly, illuminate by a nightlamp castings subdued glow on the sheets. Her mother was on her back, with her legs wrapped tightly around Katy's father's midsection. She groaned like a wounded animal as Ken hammered his cock into her hairy cunt.

"Give it to me, Ken," Katy heard her mother whisper. "Oh Christ, that feels so good. I wish you'd fuck me more often! Unh, God! My pussy needs your prick!"
