While she was on a trip with her family for four days, she had sex with her childhood friend crazy.

My childhood friend Hiromu has a cute girlfriend. That's when I realized it. I came to the conclusion that I "love Hiromu-kun." But I always wanted to keep this feeling deep inside. But that day I saw it. Hiromu is having sex with her... As I watched that... I couldn't hold it anymore... A record of her having sex with her childhood friend while she was on a trip with her family for four days.
