Incestuous siblings' secret lust

In a cramped attic, a brother and sister, bound by blood and circumstance, succumb to their taboo desires. Her fingers dance over his abs, tracing the V that leads to his engorged cock. He groans, pushing her hand away, but she persists, wrapping her lips around his shaft. He returns the favor, burying his face in her pussy, licking and sucking until she's writhing. Then, with a primal growl, he flips her over, slamming into her from behind, their bodies slapping together in a dance of forbidden lust.
