Lathered up and horny, the siblings can't deny the intense attraction between them. The sister's soft hands glide over her brother's muscled body, suds dripping down as she strokes his growing erection. He groans, grabbing her slippery breasts, pinching her nipples. She leans in, taking his cock into her mouth, sucking him off enthusiastically. But he wants more, pushing her against the wall, lifting her leg, and sliding his hard cock into her wet pussy. He fucks her hard, the sound of their bodies slapping together echoing in the steamy room, until they both come undone, panting and spent.
