[JPN] Shinobudama 忍玉 – Senpai Nugashi センパイヌガシ
There are 2 endings (that i know about) with this flash game.
Good Ending: You confess your feelings and the feeling is mutual. You move in with your senpai and fuck like wild monkeys.
Bad Ending: You disgust your senpai and you blackmail him. He then is forced to “service” men for who knows how long.
There is also a small flash game in the end where you try to lick your senpai’s dick. Keep clicking until he cums.
