After being exiled by her own sister, Saki Michino roamed the streets until she chanced upon Renta Ota's apartment. Upon finding her unconscious, Renta kindly offered her shelter. However, Saki, being no ordinary woman, required a man's essence to control her pheromones, lest her irresistible allure cause men to lose control. Sadly for Renta, Saki refused to seek donors and would rather be with someone she truly loved, which was the cause of her ostracization.
Renta's existence was rocked by Saki's pheromones, leading to a perpetual state of arousal. In spite of their precarious arrangement, they may finally uncover the fulfillment they both have been yearning for.
