Yuna as Kawaii, a beautiful nurse with a big butt and an extremely charming body. Today she came to take care of Matsuda-san, an old man who suffers from short-term memory disorder. Constantly rubbing his uncle's body with his breasts, dressing sexy to reveal his big buttocks and then deliberately showing it in front of the old uncle. Use your mouth to feed Matsuda-san, clean your uncle's cock with your own mouth! Thanks to Yuna's special "care", Matsuda-san's sexual desire is gradually revived! And since then, the two have been fucking each other every day, and each time, Yuna has squeezed out the old uncle's sperm to the last drop...
