I managed to get a job as a caretaker after turning a certain age. It's a women-only dormitory, and the women there, who don't see me as a man, are careless, showing off their changing clothes and defenseless panty flashes freely. Despite my age, my erection never subsides, and the women's sexual desires explode, leading to a period where I can have sex with them freely! Nighttime, reverse nighttime, daytime when no one is at the dorm, I'm invited by the women... and dreamily licked all over by everyone.
