Akira had a boyfriend in her student days whose sexual compatibility was perfect. Their sexual compatibility was so good that she couldn't think about anything else. She thought it would be bad to continue like this and decided to break up, but even now, as she is about to marry the fiancé she met after becoming an adult, memories of that ex-boyfriend remain deeply etched. Amidst all this, I received an invitation to a class reunion. I tried to skip it because I was afraid of running into my ex-boyfriend, but my fiancé went ahead and replied that we would attend. Reluctantly, I ended up going to the reunion and faced exactly what I feared. Reuniting with my ex, just having him touch my shoulder brought back memories of that day when I went crazy for sex. Swept away by the surging impulse, thinking 'just this once...', I ended up at a hotel, forgetting about my fiancé waiting at home and getting lost in sex with an ex-boyfriend who knew all my erogenous zones.
