In the confines of the shower, brother and sister shed more than just their clothes. As the water cascades over their naked forms, they can no longer deny the electric charge that pulses between them. She reaches out, her hand wrapping around his thick, veined shaft, stroking him until he's rock hard. He groans, his hands cupping her full breasts, thumbs brushing against her stiff nipples. Their bodies press together, her hips grinding against his, seeking friction. He lifts her, impaling her on his cock, her back pressed against the cold tiles. They move together, their bodies slapping against each other, the sound of their lovemaking drowned out by the pounding water. As they come, they bite back their cries, their bodies convulsing with the intensity of their taboo union.
