Humans reveal their true nature when they are exhausted, stripped of physical strength, intelligence, and mental fortitude. Even someone as tough as Yotsuba Alice would show an unfiltered eroticism never seen in adult videos if she were to endure a marathon-like situation with no end in sight, surrounded by endless debauchery. An utterly exhausted woman is erotic; when her usual energy and performance are drained, leaving only 0.1 millimeters of willpower, men go full power. Sex on the brink of a technical knockout. It's incredibly erotic.
