In a cramped, dimly lit room, Affu and Mass, step-siblings and students, nervously strip down to their underwear. Affu, the elder, has a mischievous glint in her eye as she teasingly pulls down her panties, revealing her bare pussy to Mass. Mass, hesitant but aroused, gradually exposes his hard, virgin cock. They tentatively touch each other, Affu's fingers wrapped around Mass' shaft, Mass's thumb grazing Affu's clit. Their first time is a clumsy, passionate dance, their moans echoing in the small space as they finally break their taboo.
