Hangs her head

She cant refuse, she knows she cant.

Her hand carefully picks up the large dildo from her desk, looking along its veiny length she couldn't denie that even as she stood there her cunt was practically dripping. She carefully lowered her tight pants and revealed she had followed instructions and had not worn any panties. Then she dropped back into her chair and rubbed the head of the dildo against her cunt.

Just then there was a loud knock on the door.

"Proffessor? I know your in there. Please, its important!"
