We fulfilled their wish by having the fair-skinned beauty "Kikuchi Kumiko" and the cute baby-faced "Tsuruno Yuu" experience an abnormal 4P play. Initially, the two couples enjoyed their own intimate activities separately, while watching each other's play, they heightened the stimulation and excitement. Thrilled, the four gradually mingled together. Being simultaneously teased all over their bodies by the other three, they drowned in a pleasure they had never experienced before. Without rest, all their erogenous zones were stimulated, leading to great excitement, and it seems they thoroughly enjoyed their "first 4P," opening the door to new thrills. Now, will they be able to satisfy themselves with normal sex in the future?...
