The old man starts French kissing her as soon as he arrives. Not knowing Hachino's figure, he looks surprised when he sees her breasts. "The boobs that kill old men" keep him rock hard the whole time in the mixed bath. His excitement keeps building, and at night he gulps down his love juices with seaweed sake. The two get along well and have sex at night, engaging in a French kiss that gets their tongues tangled. Their naked bodies, slippery with sweat, press against each other intensely, and before they know it, Hachino is in an unconscious crab position (forgetting for a moment that they're being filmed).
