Need help finding BL manga one shot

Hello! I need help finding this BL manga one shot. The story starts with a cuckold-themed plot; there is a man who is disabled and have to sit on a wheelchair, and he was not able to have sex with his wife. Thinking of finding ways to please his wife, the man asked the housekeeper/gardener guy to have sex with his wife, while the man would watch his wife and the gardener/housekeeper guy having sex. Later on, when the wife is absent from the mansion, the gardener/housekeeper guy starts to make advances on the husband, and the two of them later have sex.
