College coed Sera Ryder, with her voracious appetite for knowledge, has been exploring the naughtier sides of life's textbooks. Alone in her bedroom, she puts her newfound skills to use, fingering her wet pussy and stroking her big ass. Her stepbrother, Tony Profane, walks in on her, and what starts as an argument ends with them masturbating openly in front of each other. Sera's eyes widen as she takes in Tony's thick, straight cock, fantasizing about feeling it inside her. Just as they're about to act on their desires, someone enters, leaving them breathless and forced to pause their intense encounter.
