Kakeru, who suffers from premature ejaculation, and his girlfriend Maki, who suffers from frigidity, find a clinic that can solve their problems.Although they felt a little suspicious, they decided to go as a couple to improve their sex...for the sake of each other.The two of them are separated into separate rooms and guided.Kakeru's doctor, Serizawa, is a somewhat bewitching older sister with big breasts.The treatment started immediately, with a teasing hand job to get used to the stimulation, and a rich slow blowjob... She reacted twitchily, and after her masochistic nature was revealed, she repeatedly exploded while being played with every time she visited.``Aren't you curious about what Maki-sama is doing?'' While Kakeru was being made to cum pathetically... Maki was having every erogenous zone developed by a rugged male doctor and was cuckolded...!The distorted shape of love depicted by the extremely popular circle ``Shirasudon'', which also boasts an overwhelming number of copies of its other works, and the [new sensation of masochist NTR] that intersects with immorality and regret are amazing...!
