In the dim light of the closet, Michelle and her brother stand close, breaths ragged with anticipation. Michelle, still a virgin, looks up at her brother with wide, nervous eyes as he slowly unbuttons her shirt, revealing her small, firm breasts. He reaches down, feeling her wetness through her jeans, and she gasps, her body betraying her with a surge of desire. She tentatively touches his cock, feeling its hardness and length, before sinking to her knees, taking him into her mouth. He groans, grabbing her hair, and she moans, the vibrations making him throb. He lifts her up, turns her around, and enters her from behind, her tightness making him groan as he pumps in and out, their bodies slapping together in the quiet house, their moans muffled by the clothes around them.
