A beautiful girl named Airi, who suffers from anorgasmia, receives a shocking diagnosis from her doctor. She was born with a unique constitution: her clitoris is not in her vagina, but in the back of her throat. Airi is unable to hide her shock, but she discovers that by continually stimulating her throat clit, she can experience a double orgasm of the throat and vagina, something that ordinary people cannot experience. After that, Airi is violated deep in the throat by many men, and she blossoms as a throat clit woman, finally obtaining unprecedented pleasure.
