At a class reunion, Tsumugi meets a friend she hasn't seen in a while and starts talking about having a child, and decides to go to an obstetrician-gynecologist in preparation for trying to conceive. The doctor in charge was a bespectacled man who called himself Usami, and after finishing the examination he handed Tsumugi some painkillers and urged her to take them. Apparently it can sometimes cause drowsiness as a side effect. Then, after Ozawa had watched her fall into a deep sleep, he devoured her limp lips, licked her body, and inserted his cock into her defenseless pussy. All of this happened without my knowledge...but the pleasure I felt at that time remained in my body even after I woke up...
