The creaking floorboards and muffled voices outside the closet door only serve to heighten their arousal. Michelle's breath hitches as her brother's thumb finds her clit, circling it expertly. She can feel his cock throb in her hand, and she leans in, whispering, "I want to taste you." He nods, his eyes wide with desire, and she takes him into her mouth, swirling her tongue around his head. He groans softly, his fingers never ceasing their dance on her pussy, and they lose themselves in their forbidden dance, their bodies yearning for release, their souls heavy with the weight of their transgression.
