Mitsuki Mitsuki, a cheerful and lively girl, is popular in the adult video industry. However, she harbors a secret concern: "I'm so sensitive that I climax too quickly, and I'm never sure if I'm truly satisfying my partner." To help her overcome this insecurity, we introduce her to amateur premature men who share the same struggle. Through their encounters, they bond over their shared sensitivities and gradually learn to understand and accept each other. Initially, Mitsuki worries, "Maybe guys won't want someone like me who cums too fast," but as she witnesses the intense reactions of these sensitive men, she slowly opens up, experiencing a deeply maternal, mind-blowing connection. Even under the clumsy yet passionate advances of the premature men, she repeatedly reaches climax, and together, they engage in intense, genuine sex where both partners fully satisfy each other, sharing their peaks and depths completely.
