Sensei Wa Sonna Koto Oshietenai!
(Book series 1) oof so good!! [Masaki Tsuji is a divorced high school teacher in his early 30s. Lately, he's been running into a groper on his train ride to work. At first, he thought it was a mistake, but once the hand reaches around the front, things start to escalate! Then a voice whispers, "You're cute, Mr. Tsuji." He can't stop thinking about the perpetrator all the way to school. When Sohta, a student who usually gets good grades, hands in a blank test sheet, Masaki calls him in for a talk. They meet after school, and once Sohta confirms that they're alone, he goes in for a kiss! Sohta whispers to a panicking Masaki out of the corner of his mouth, "Have you been getting groped on the train recently?" Sohta ties him up and starts playing with his body...! This is a secret school love story between a handsome student and his 30-something teacher!]

(Book series 3) lol i mean it was alright [Haruki is a school nurse by day, natural-born manhunter by night. Lately, though, he hasn't been able to catch any prey. As his frustration reaches a boiling point, he is approached by a mysterious young man named Shion. "Give it up. I'm only gonna stop you." Haruki laughs this off, believing it to be some kind of immature revenge plot. Shion seizes this opportunity to push Haruki down and bind his hands. In a state of rapture, Shion says, "I've been told I'm pretty good. So, all you gotta do is sit back and take it." Despite not usually being on the receiving end, Haruki can't help but lose himself to the pleasure...! Sequel to Sensei no Iukoto Kikinasai!]
