Yuko, reuniting with her old school friend Megumi at Megumi's home, was enjoying wine together after a long time apart. That's when Masanori, Megumi's husband—completely different from Yuko's own husband—returned from work. Elegant and charming, with a lovely face, a beautiful cleavage, and a naturally curvaceous figure from her narrow waist to her hips, Yuko's beauty far surpassed his own wife's. Instantly smitten, Masanori struggled to suppress his sexual desire with reason—but upon witnessing a certain scene, all his self-control came crashing down.
