I Took A Succubus's First Time - Chapter 280: What exactly is this benefit you mentioned?

“Sect Master! Marry me!”If only things were that simple.Fang Yuan lets out a long sigh, eyes fixed on the mountain of paperwork threatening to swallow his desk and his soul.As the youngest family head in history, you’d think he’d be enjoying fame, fortune, and fawning admirers.Instead, he’s buried in bureaucracy, stuck mediating elder disputes, and wondering if the sect treasury mysteriously eats spirit stones.Sure, the old geezers have their experience, their beards, and their lofty reputations.But Fang Yuan? He has one thing they don’t: raw, unshakable power.Born into a world where innate talent reigns supreme, Fang Yuan—a transmigrator armed with modern grit—actually managed the impossible: he clawed his way to the top with nothing but relentless hard work.While everyone else coasted on heavenly bloodlines and golden physiques, he trained, he studied, and he schemed.Now, he’s strong enough to bend heaven’s will.But cultivation isn’t all sword beams and glory.Life as a family head comes with its own set of woes—namely, watching his annoyingly handsome junior brother collect all the female attention like some kind of walking romance novel.“This isn’t fair,” Fang Yuan mutters under his breath, stamping another scroll. “I’m the protagonist here... right?”

After dying in an oddly anticlimactic vending machine accident, Kazuki Ren is reincarnated in the demon realm—not as a hero, not as a villain, but as the only human male student enrolled at the mysterious Academy of Ruin, a school where all the professors are demon lords and all the students are powerful, beautiful she-demons.Ren is told he has one task: survive.But there’s a catch. The Academy’s darkest secret is about to awaken, and Ren holds a hidden power that could either destroy the demon world... or rule it.Now surrounded by seductive demons with hidden motives, eldritch tomes, forbidden dungeons, and twisted exams, Ren must master his ability—or be consumed.Magic, mystery, danger, and temptation await in this dark academia harem fantasy.

It doesn’t matter if he transmigrated into the ML’s little brother (TN: Here I think brother disciple) or master or opponent, but in the end he is still forcibly taken by the ML.
