Melody, Shane, and Sissi, the Dollscult siblings, transform into a human sex doll, a master, and a willing participant in this taboo threesome. Melody, the doll, lies prone as Shane, her stepbrother, feeds her his throbbing cock while Sissi, her stepsister, watches, her own desire evident. They switch positions, Shane pounding Melody's tight pussy from behind as she sucks Sissi's clit. The room fills with moans and the sound of flesh slapping flesh. Finally, Shane can't hold back, pulling out and covering Melody's face in thick, creamy cum, leaving her looking like a real-life sex doll.
