The long-awaited second work from Nanaumi Tina. Her desire to "make men feel good" and "keep doing it until I'm so exhausted I can't stand" is fulfilled. It brings out the extreme psychology of being the most erotic when you're tired, and expresses the image of a woman drowning in sexual desire. With the theme of "becoming positive about sex," this is a four-part series that includes squirting sex.
