In the summer of western Tokyo, a sweaty young girl is being licked by an elderly man. It's now the Reiwa era. I'm almost 65 without even realizing it. Because my "married sister" is having an affair, I have to temporarily take care of her daughter, Saki, for three days. Saki has grown even cuter, which makes me, an elderly man, extremely happy. It's the height of summer now, and it's hot every day. There's no bathroom, I'm sorry, Saki. I can't stop sweating. I'm sorry, Saki. I can only endure it for three days. Please forgive me even if I give you pocket money. And after I give you pocket money… can I lick that body? Those fair, delicate fingers… sweet and sour… remind me of my youthful days. I haven't seen Saki's vulva in ten years. The thick hair… the elderly man is extremely happy, pushing himself to the limit.
