A fake show is staged with three idols spending a night and two days at a hot spring inn! The purpose is to have old men sneak into their rooms at night! The gathered old men are disguised as inn staff, interacting with the three idols. Once they find a girl they like, they will sneak into her room at night, and we'll observe if they can get an erection and ejaculate. Will these old men be able to ejaculate in their state of excitement? Or will they just uselessly lust after young women?
