Wrex Oliver, the generous stepbrother, catches Luna Daniels, his tiny stepsister, in a compromising position - her hand buried in her panties, her body writhing with pent-up desire. Instead of walking away, he stands at the doorway, his massive cock tenting his shorts. Luna, emboldened by her newfound curiosity, beckons him closer. They tumble onto her bed, a tangle of limbs and moans, as Wrex's thick cock stretches her tiny, untouched pussy, giving in to the taboo lust that's been building between them.
