It is a nudist beach

"What is it?" Kirsten asked.

"In the 70s there was a group of hipsters that complained there wasn't any space for nude recreation. So they went to the city council and demanded a beach for nudists, which they gave them right on the opposite of the lake. Because it was so far away from the city center and such a long walk through the forest it was a disaster. When the beach opened the people who demanded it to come didn't even bother to show up. Thus this is one of the pearls of our city where you can suddenly be all by yourself, save for a few joggers every hour or so."

"Wait. This is a nudist beach?"

"Clothing optional actually. You don't need clothing, but you also aren't **** to wear them. You could wear anything you want here."

"I see where you're getting..." Kirsten said. "I have to strip here right?"

"And I brought diapers too." Said Sarah. "It's up to you really. If you want to be nude or diapered you can. Nothing holds you back."

"Won't I be seen?"

"If you want to you can. About 3 joggers each hour pass here. You can see them coming from the distance over there, so you could hide when they pass."

"So I could be nude here without anyone seeing me?"

"Yes. But that isn't really the goal of today." Said Sarah. "You've let go of your secrets, your identity and yesterday your decency. But you did it hidden. Today you should do the same, but in the open."
