Father

You're finger fucking yourself faster and faster, your hips lifting off the bed to meet the thrust while your other hand pinches those perky nipples of yours. Moaning loudly, you don't notice you're being watched though until the door opens.

"John!"

Glancing up in shock as your father enters the room, you stare at his muscular body. There's sparse hair over his chest and going down to his happy trail. His boxers are barely concealing his huge erection.
