Shikano Amo plays a busty idol with pride, but at the same time, extreme sexual preferences. She takes on the challenge of "throat insertion deep throat," where a cock is thrust deep into her throat to its limits. Her pure image as an idol is completely destroyed by the humiliating service, covered in sobs and saliva. With tears in her eyes, she swallows the cock, and the caresses that make her throat tremble bring the man's possessiveness to a climax. This is a record of an immoral deep throat, tainting the idol with semen and saliva, and peering into her abyss.
