Maki and Meiling enjoy going on hot spring trips to relieve the fatigue of their boring housework. The two are disappointed when they visit a hot spring inn without knowing that it is a mixed bathing facility... They wait for a moment when no one is there, but at the worst possible time, a male guest shows up! The men are excited by the married woman's body and decide to show off their large penises that have grown as a result of their pranks! The two are so excited by the penises they haven't seen in a long time that their frustration explodes! They shake their hips and perform a fierce cowgirl position to make the man cum!
