Following her confession of love and shared kiss with childhood friend Kaoru, our heroine found herself in desperate need of release to quell the burgeoning excitement within. To satisfy this daily requirement, she engaged in self-pleasure while immersed in provocative material. Unbeknownst to Makoto, her stepbrother surreptitiously observed these intimate moments.
