TW: non-con, mind control

• Part 1: Ebihara is appointed to teach the ropes to Kanbe, who has just been hired. Kanbe used to work as a masseur, and seemingly joined the company because he knew the CEO from his previous job. That's also why he offered to give a massage to Ebihara. As Ebihara agrees to it, Kanbe takes this opportunity to give him a brainwashing massage, and he turns Ebihara into his cumdump, training his ass and nipples.
• Part 2: Shuichiro Ebihara, a single father who has been brainwashed, has now been fully trained by Kanbe, his subordinate. However, he resists him when Kanbe tries to make a move on him at work, and to make up for that, he ends up agreeing to be used by him freely, whenever they're not working. Like that, Kanbe made all of Shuichiro's free time his. "I wanna have sex at your place", said Kanbe, which is why Shuichiro is now bring him home with him, so that they can fuck there.
• Part 3: Yuya is the second son of the Ebihara family. Yuya is made to feel no discomfort about his about his father and Kanbe's relationship by Kanbe's brainwashing massages, but he is aware that there is something unusual about their relationship. One day, while taking a bath with Kanbe, Yuya comes out to him: he likes a friend from the same baseball club. Kanbe then says, "I'll turn him gay for you." Yuya brings his friend over and has Kanbe give him a brainwashing massage.
