In the dimly lit study, Katrina and Paul's secret tryst begins. Paul's hands, strong and commanding, grip Katrina's hips, pulling her against his growing bulge. Katrina, her heart pounding with fear and excitement, unzips his pants, revealing his throbbing cock. She takes it in her mouth, tasting the pre-cum, her pussy dripping with anticipation. Paul lifts her onto the desk, pushing her legs apart, and enters her with a force that makes her gasp. Their bodies move in sync, the creaking desk a symphony to their forbidden lovemaking, Katrina's cries of pleasure echoing through the house, a testament to their fucked-up family dynamics.
