In the dim light of the closet, siblings huddle, their breaths ragged with anticipation. Michelle, her heart pounding, guides her brother's massive cock to her dripping entrance. Clad only in their underwear, they tremble, the taboo of their act hanging heavy in the air. Michelle gasps, feeling every inch of him stretch her tight pussy. They move in sync, their bodies slick with sweat, forgotten prayers echoing in their minds. The creaking floorboards threaten to give them away, but they can't stop. Michelle's moans are muffled by her brother's shoulder as she claws at his back, her orgasm building. They collapse, spent, in the aftermath of their sinful pleasure, panting and guilty, yet hungry for more.
