Siblings' secret: Forbidden lust in the closet

In the dim light of their shared bedroom, a brother and sister, both restless and horny, can't resist the magnetic pull of their forbidden attraction. She teases him, parading around in her tiny sleepwear, her nipples hard and visible. He responds, his bulge tenting his boxers. They circle each other, the tension thick, until she finally straddles him, his stiff cock pressing against her wet panties. They grind, pant, and kiss, their hands exploring each other's bodies, but just as they're about to cross the final threshold, a parental voice echoes through the house, reminding them of the danger they're playing with.
