I called for a "promotional girl," but it turned out to be a colleague from work... From today onwards, this woman is my unprotected, big-breasted toy. (Hisaki Alice JUFE-369)

Exploiting my tacky colleague's weakness, I subject her to physical training and discipline! I called a prostitute over from my place, but instead, it was my usually mature and tacky colleague, Sena Hikaru. She begged me to switch her out, but since she was already there, I figured I might as well have some fun...
