Soft-spoken amateur Fukuda Yuko comes to the shoot because it sounds fun, then reveals that she specifically loves unwashed cock. When her partner offers to shower first, she refuses and immediately takes his shaft into her cute mouth, sucking so eagerly that he unloads a heavy mouthful of semen. He tries to pause for a shower afterward, but Yuko insists on cleaning him with her tongue and continuing as he is. Her innocent appearance hides a wildly horny side, and she surprises him again by suddenly taking the cock inside her.
