In the cramped confines of their shared bedroom, the siblings struggle to contain their lust, their eyes locked as they silently agree to their forbidden act. Michelle, her breath ragged with anticipation, reaches out, tentatively touching Timmy's thigh, her fingers tracing the outline of his hardening cock through his thin pajama pants. Timmy's breath hitches, his hips jerking slightly as Michelle's touch sends electricity coursing through his veins. He reaches out, his fingers tangling in Michelle's hair as she leans in, her tongue flicking out to taste the pre-cum beading at the tip of his cock. Timmy's grip tightens, his hips pumping as Michelle takes him into her mouth, her cheeks hollowing as she sucks him deep, her eyes watering as she struggles to take his length. The room fills with the wet sounds of Michelle's mouth and Timmy's ragged breathing, the scent of sex hanging heavy in the air as they succumb to their taboo desires.
