Alright so the one I'm looking for was on Fakku, before they removed all the free content. Now the content of the Manga was a student council. I remember the Student President was female, long hair, big breasts, and had a submissive/exhibitionist streak. I think he was the VP, main male had short hair, light coloured, bangs always covered his eyes. He was dominant and very sadistic. There were two others, a masochist who got horny when she stubbed her two, a guy who didn't want any part of this nonsense, and agirl who was the student council member. Significant things I remember was that in one chapter, that guy who didn't want anything to do with this nonsense, got drunk and slept with his older sister, who was an utter bro-con. It turned out the one who'd coaxed her into getting the brother drunk in order to sleep with him was someone she referred to as "Master" (in the teacher sense), who turned out to be the council's Vice President.It was revealed in one chapter that how the President and VP met was she was posting photos on a website, and he started blackmailing her. It turned out the reason he found the photos was that he was actually the one moderating that website. I remember one chapter after that reveal that the President ran off angry, and ended up running afoul of three guys. She THOUGHT she'd be up for what they wanted, as it met her fetishes, but something felt wrong to her and when she tried to get out of it things went poorly. Before she ended up getting raped though the VP showed up and beat the three guys up. He either had a taser or a stick. He tied them up and had sex with the President right in front of them. At the end of the manga everyone but that third new girl graduated and left the student council, and she was the new President, but when she walked into the student council room they were all still there. This was because as it turned out, the college was on the same campus as the highschool.
Pic unrelated. Tits just get more looks.
