In the quiet of his room, a man lost in fantasy, pictures his obedient step sister on her knees, eager to please. She gazes up at him, innocent yet hungry, as she wraps her soft lips around his throbbing cock. He groans, guiding her head, dirty talk flowing freely. She takes him deep, her tongue swirling, her hand stroking in rhythm. He can't hold back, his body tensing as he explodes, his hot cum filling her mouth. She swallows every drop, licking her lips, her eyes never leaving his.
