Mitsuki Kamiya is a cheerful girl. She has the brightest image in the AV industry, but she has a problem: "I'm too sensitive, so I always cum right away, so I'm worried about whether I'm entertaining men..." This time, we're going to have her meet and interact with an Amateur premature ejaculator who is in the same situation, so they can share and empathize with each other's complexes and solve their problems. At first, she's pessimistic, saying, "A woman like me who cums right away...", but every time she sees the sensitive reactions of the premature ejaculators, she becomes more and more open-minded and has a brain trip of maternal explosion. And she climaxes over and over again when the premature ejaculator counterattacks with his clumsy hands! A sensitive woman and a premature ejaculator share each other's foreheads and bulges to satisfy each other in this hardcore sex!
