Avery Adair, the busty blonde stepsister, finds herself in a bind with her upcoming exam. She enlists her stepbrother, Rob Carpenter, to help her study. As they go through the material, Avery's distraction grows, her eyes wandering to Rob's intellectually stimulating mind. She decides to reward him with a blowjob, her full lips wrapping around his hardening cock. Rob, caught off guard but clearly enticed, reciprocates the favor, his tongue exploring Avery's tight, wet pussy. Their studying session transforms into a heated, lustful encounter as Avery straddles Rob, riding him with the same enthusiasm she'd put into acing her exam.
