In the stuffy attic, the cousins, bound by blood and newfound desire, succumb to their taboo lust. She, in a simple white dress, straddles him, her pussy rubbing against his hardness. He, in boxers, tentatively touches her through the dress, feeling her wetness. They strip each other, their breaths coming in short gasps. His virgin cock stands tall, ready to break her hymen. She impales herself on him, wincing at the pain, then moaning as pleasure takes over. They fuck hard, their young bodies slapping together, their voices echoing in the attic. They come together, their bodies shaking, their first time a messy, sweaty, beautiful union.
