Yumi, 25 years old and married for four years, joins Tamura Soichiro on an affair-filled trip. Despite her tomboyish personality, she has a stunning figure and ends up allowing creampie after creampie, surrendering to two deep inside her. Meanwhile, Kumiko, 34, exudes lustful pheromones and constantly craves cock throughout the trip. Even after four creampie loads, neither woman seems satisfied, left with an undeniable hunger for more.
