The Shark's Bathhouse(18+)

"The Shark's Bathhouse" is an adult-themed, 18+ megaman-like platformer featuring a fox protagonist on a mission to defeat the big bad shark daddy at his bathhouse. Gameplay involves jumping, shooting, and "humping" to progress through levels, with two possible endings. The game is free, but paying $2 or more provides access to a gif set of all NSFW scenes.
