Cloaked in the dim light of their shared bedroom, a young sister and brother succumb to their lustful urges. She's a virgin, untouched and aching, he's a curious teen, hard and eager. Their bodies pressed together, they grapple with their religious upbringing, yet their hormones win out. He slides his cock into her tight, untouched pussy, her moans echoing through the silent house. They fuck with abandon, their bodies slick with sweat and juices, their minds clouded with sinful pleasure. As they reach their climax, they're forever changed, bound by their taboo tryst.
