Briana, my Colombian step-sister with a wild side, walks in on me pleasuring myself, her brown eyes widening at the sight of my throbbing cock. Instead of storming off, she licks her lips, her tiny frame shaking with excitement. She climbs onto the bed, her small tits bouncing in her sexy lingerie, and takes my length into her mouth, her tongue swirling around my sensitive tip. I grab her hair, guiding her as she sucks me off, her brown skin glistening with sweat. She's a geek in the classroom, but in the bedroom, she's a goddess, taking me deep until I can't hold back any longer, my hot cum filling her mouth.
