Bound by faith and family, two siblings struggle against their burgeoning desires. She's a picture of innocence in her white nightgown, but her eyes betray a hunger that matches his. He's temptation personified, his muscled frame barely contained in his boxers. They circle each other, their bodies aching for contact, their breaths coming in short gasps. Finally, she can't resist, pressing herself against him, feeling his hardness through the thin fabric. He groans, his hands cupping her ass, pulling her closer. They're lost in their passion, their bodies moving in sync, until a sudden, harsh knock at the door jolts them back to reality, leaving them breathless and guilty.
