Prompt

The picture shows an onsen, a traditional Japanese hot spring. In the background there is a dark night. There are five naked women belonging to an idol team there. They have different colours and types of hair, but all of them are equally beautiful and have sexy bodies, with massive tits, slim waist and long legs. They sit in the hot spring, relaxing in warm water while talking with each other. Two of them are kissing. Most of them are masturbating with each other, touching their friends when others touch their pussies. It's a big lesbian orgy.
