In the dim light of their shared room, Michelle, a curious and impressionable teen, finds herself drawn to her brother's growing bulge. His voice wavers as he lectures her about her upcoming 'womanhood,' fueling her curiosity. She tentatively reaches out, touching his hardness through his jeans. He gasps, his cock twitching. Boldly, she unzips him, revealing his thick, pulsating member for the first time. His breath hitches as her small hand wraps around it, exploring its length and width. She leans in, her tongue flicking out to taste the pre-cum beading at the tip, igniting a taboo connection.
