I'm a regular high school student, and when I confessed to my classmate Kotone, she surprisingly said yes right away. She's an honor student, the kind of girl you could proudly introduce to your mom. But behind that sweet exterior lies a shocking secret—she's been secretly dating a 40-year-older gym teacher and even giving him blowjobs at school. Ever since we started going out, she's been taking me to her room, making me cum repeatedly, and putting me through all sorts of wild sex acts. Even more shocking, I later learned she once had a "possession battle" with her fourth boyfriend, fighting over who gets her. Eventually, I found out she actually has ten boyfriends in total. Kotone's a natural-born nymphomaniac who loves full-body kissing, adores blowjobs, creampie sex, and swallowing every drop. Yet her sweet and adorable personality makes me forgive her no matter what.
