Even though I had my first girlfriend, I kept succumbing to the whispering temptations of the beautiful female teacher, Mizuki-sensei... I lost my virginity, and had my first kiss, first blowjob, and first sex, which I had never done with my girlfriend... and even creampied her! Even though I have someone I love and I know it's wrong... I can't stand Mizuki-sensei's provocations, which escalate more and more, and my dick keeps getting fully erect! I get so excited that I can't help it, and I end up ejaculating inside her! Tormented by the guilt of having a girlfriend, I cheated on her and creampied her over and over again...
