Nerdy Sister Helps Him Pass Big Test in Exchange for Hot Fun

He knows he will fail the upcoming exam unless his stubborn Sister tutors him but she refuses until he steals her glasses to make a deal. She ends up sucking his thick cock surprisingly well and later shows him filthy tricks she learned from her secret erotic books. A couple days after he aces the test she rewards him by climbing on top for a deep ride that drains every drop from his balls leaving them both satisfied.
