Living alone, Takashi collapses with a high fever, prompting his aunt Hana to stay at his apartment to nurse him back to health. Once harboring secret feelings for Hana, Takashi—delirious and half-conscious—moans in his sleep from a vivid erotic dream and climaxes involuntarily. Seeing Hana gently wipe his body, reassuring him, "It's just a natural reaction, there's nothing to be ashamed of," pushes Takashi to his limit. Overcome by uncontrollable desire, he pins Hana down and forcefully thrusts his engorged cock deep inside her.
