Professor Enokido's hit work 'The Serious Swimmer, Drowning in Sex' is being adapted into a live-action film with innocence and grandeur! The girl Kei Yuikawa, who is dedicated to swimming, offers her body to a senior who is known for his womanizing ways, all to save the club from disbanding. 'He's the lowest of the low, but his talent is necessary for this swim team...' With that justification, she agrees to sex, but after repeating the act, she becomes addicted to her senior's dick...! The AV original part also includes an epilogue. The serious girl's fall into pleasure is the most erotic.
