Sinful Siblings' Secret Surrender

Two siblings, bound by blood and guilt, find solace in each other's arms after their devout parents catch them masturbating. Locked in the attic, they surrender to their taboo desires. The sister, a virgin, tentatively takes her brother's cock into her mouth, tasting pre-cum as he groans. He returns the favor, licking her pussy until she orgasms. They fuck, their bodies slapping together, until they're spent and panting. Afterwards, they pray together, seeking forgiveness for their sinful lust.
