Kichiku Megane (visual novel)

A Boys Love Eroge by Spray (the developers of Gakuen Heaven), which roughly translates to "Brutal Glasses".

Saeki Katsuya is a hapless salaryman, whose life takes a turn for the better (or worse?) when he meets a mysterious man who offers him something that he promises will benefit him -- a pair of glasses. These aren't just any pair of ordinary glasses, of course. They turn the wearer into an extremely competent, confident businessman -- as well as a domineering, sexually aggressive brute.

The game is notable for allowing the player to either be dominant or submissive, a "kichiku meter" that gauges the player's acts of brutality, and Selfcest between the Katsuya and his "megane" self. Also has a sequel (Kichiku Megane R), manga versions, drama CDs and light novels.

Recommended if you're looking for a hardcore BDSM yaoi game.

Tropes used in Kichiku Megane (visual novel) include:

• Badass Longcoat/Badass Long Hair: Mr. R
• Bastard Boyfriend
• Berserk Button: Taichi in R. seeing Katsuya getting raped will likely have his hands covered with blood.
  • Megane!Katsuya also has one in R, specifically Midou's route.
