Erik and Karol, step-siblings bored and horny, retreat to their rooms for some private time. Erik strokes his thick cock, fantasizing about Karol's luscious body. Karol, in her room, plays with her clit, imagining Erik's big dick inside her. Their moans echo through the house, drawing each other in. Erik enters Karol's room, catching her mid-act. They freeze, then smile, deciding to continue together. Karol watches Erik's massive cock grow, licking her lips. Erik jerks off, enjoying Karol's eager gaze. They edge each other, their bodies tense with anticipation, until someone's footsteps force them to pause, leaving them both breathless and unsatisfied.
