I got a girlfriend for the first time...I succumbed to the whispering seduction of a beautiful teacher and cheated on me again and again...

Even though I had my first girlfriend, I continued to succumb to the whispering seduction of a beautiful female teacher, Mizuki. Her virginity is taken away, and she has never had a girlfriend before, first kiss, first blowjob, first sex...and even creampie! Even though there's someone I love, I know I can't get any good... I can't stand Mizuki-sensei's provocation as it continues to escalate, so my dick can't stop getting a full erection! Immoral ejaculation that will make you so excited that it's impossible! ! I was tormented by the guilt of her being there, and I cheated on her again and again...
