In the dimly lit room, the young step-siblings, Scarlett and Alex, could barely see each other. They were both excited and nervous about what they were about to do. Scarlett, who had just turned 18, had always been curious about her younger brother's body. She moved closer to him, her heart racing as she took off her shirt revealing her perfect tits with hard pink nipples. She slowly unzipped Alex's pants, releasing his long, hard cock which twitched in anticipation. Without another word, she wrapped her lips around the head of his cock and began to suck, moaning around it as she took him deeper inside her mouth. Their taboo act fueled their lust for each other. Scarlett stood up, taking off her pants and underwear, revealing her neatly trimmed pussy, as Lily watched, captivated by the sight of her best friend's intimate areas.
