Estefani, believing she's alone, heads to the bathroom. Crisanto seizes the moment, grabbing her on the stairs. He drags her to the room, his desire uncontainable. With a thrust, he penetrates her, fucking her hard and fast. Estefani's moans echo, but she can't cry out, not with her step-sister nearby. Crisanto finishes with a groan, his hot cum splashing across Estefani's face. 'Don't tell my step-sister,' he whispers, zipping up before disappearing.
