Despite having a beloved girlfriend, I was constantly defeated and ejaculated upon by Kana-san, a friend who is vastly more beautiful. When Kana-san discovered I was a closet masochist, she took advantage of my girlfriend's absence to toy with my sensitive body. Despite my desperate resistance, I ended up fully erect in front of her and easily ejaculated prematurely. Moreover, Kana-san actively engaged in evidence concealment! Even after that, I was forced to ejaculate repeatedly and engage in sex against my will, completely defeated as Kana-san's outlet for her sexual desires. #ClassMonitorP
