In the dim light of the closet, the siblings huddle together, their bodies pressed close for warmth. Michelle's hands tremble slightly as she reaches out, tentatively touching her brother's hardness through his jeans. He sucks in a breath, his eyes locked onto hers as she unzips him, freeing his rigid cock. She wraps her small hand around it, feeling its heat and pulsating life. Guilt wars with desire in her mind, but the latter wins as she leans down, her tongue flicking out to taste the salty bead at his tip. He lets out a low moan, his hands fisting her hair as she takes him deeper, her inexperience evident but her enthusiasm undeniable. They're both so lost in their forbidden dance that they don't hear the doorknob turn until it's too late.
