Unable to resist the temptation, she sneaks up to him, her heart pounding with excitement. She gently unzips his pants, revealing his massive, throbbing cock. Diana Grace's eyes widen in anticipation as she wraps her slender fingers around his shaft, feeling its heat and hardness. She leans in, her tongue flicking out to taste the pre-cum beading at the tip. Diana Grace's lips part, and she takes her stepbrother's cock into her mouth, her head bobbing up and down as she struggles to take in his impressive length.
