VEC-616 - Shiraki Yuko, the wife's friend, came to lecture her husband who was caught having an affair.

Yuko, having consulted about her husband's increasingly worsening infidelity, goes to lecture him in anger. However, her patience runs out with her husband only making excuses. "Women are drawn to your large penis, so you can't refuse them? If that's true, show me here now." It's probably a small penis anyway. Before Yuko, who intended to ridicule his pretense, was presented an unexpectedly huge penis. Yuko, stimulated by the unimaginable size, begins to secretly maneuver to possess the huge penis.
