In a cramped, virtual closet, two siblings, bound by family and religion, succumb to their forbidden desires. Clothed only in their underwear, they rub against each other, their bodies responding with slick lubrication. The girl, overcome with lust, guides her stepbrother's massive cock into her tight, untouched pussy. They fuck frantically, their bodies slapping together, until they collapse in a mess of spent fluids and remorse, their virtual sins forever etched in their Sims' memories.
