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 sex toy. (Yuri Ai Yoshine JUFE-195)

Exploiting my tacky colleague's weakness, I proceeded to "plant" and "train" her M-cup body! I called a "promotion girl" over to my place, but instead, it was my usually tacky and mature colleague, Yoshino, who showed up. She begged me to switch her out, but since she was already there, I figured I might as well have some fun with her...
