Mitsuha Asuha. A porn actress known as the most sexually powerful in the adult industry due to her incredible libido. Up until now, she has been brought to orgasm by every trick in the book, from intense thrusting to aphrodisiacs and bare penises. Who would have thought that in this project she would be pushed to the brink of unconsciousness and experience her most intense orgasm yet…? What happens to a woman when the thrusting continues at the same speed? Not letting her orgasm easily even when she seems close, and never stopping even when she does orgasm. A steady rhythm that isn't fast but is sure to destroy her pussy in the most spectacular way – a new realm of orgasmic AV with emotionless, mechanical, and regular thrusting.
