My Stepsister Is A Sexy Scientist - S13:E4 - Scarlet Skies

Scarlet Skies barges into her stepbrother’s room to copy his science project. When he kicks her out, she plots a very intimate revenge: proving how often he jerks off. The next day, she waits wearing nothing but a lab coat. Pretending it’s part of her experiment, she orders him to masturbate while she takes notes. But she wants more—if he can make her cum with his tongue, he gets to fuck her. Leo delivers. Scarlet moans, sucks his cock, rides him, and begs for more. When he’s about to cum, she locks him in to get filled. That was her plan all along.
