"The professor, a stern disciplinarian, calls a naughty student to his office for a special lesson. He's heard whispers of her promiscuity and decides to put her to the test. He demands she prove her worth, her slutty skills. The student, eager to please, strips down to her panties, her body already glistening with sweat. The professor, his cock straining against his pants, orders her to touch herself, to make herself ready. She obeys, her fingers diving into her wet pussy, her moans filling the room. With a growl, the professor frees his cock and plunges it into her waiting mouth. He fucks her face roughly, his cock slamming against the back of her throat. Finally, with a roar, he pulls out and sprays his load all over her tits, marking her as his cumslut."
