The 10th installment in the "Perversion Premium" series, titled "Pregnant Part 2," depicts Yoko, now nine months pregnant, succumbing to infidelity due to growing dissatisfaction with her husband. The film features extreme scenes of her being tied up with ropes around her near-term pregnant belly, dressed in a sailor uniform, and forcibly penetrated with creampie in a cage behind iron bars. Ultimately, she arrives at the ultimate den of perversion—the "Maniac's Mansion"—where she indulges nightly in the pleasures of threesomes.
