プロンプト

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. Some of them lightly touch themselves, while others are watching. Two of them are kissing.
