Throat ravaged completely!! My secret business: "Deep Throat Slave ● Brokerage," targets the natural beauty Riku, a black-haired short-haired schoolgirl. Together with my fellow throat trainers, we kidnap her and subject her to extreme deep throat training, bringing out her latent masochistic tendencies and self-degrading nature. Under the brutal assault of the penis in deep throating, she can do nothing but open her mouth wide, her throat utterly dominated to its deepest depths. Through this experience, she evolves into a rare deep throat slave ● girl, embodying unknown pleasure and submission.
