The weather changed overnight and it was cool and rainy Sunday morning. Gretchen slept in before spending a lazy morning puttering around her apartment. Petra called her and said she would be by in the early afternoon to pick her up. Gretchen took a shower, making sure to shave any stubble that had grown around her pussy, and got dressed to run some errands. When she got back, she made sure to strip again, made herself a salad, and then surfed a bit waiting for Petra. About 2:30 the doorbell rang, and Gretchen buzzed Petra up. She grinned at Gretchen when she saw that Gretchen was naked.
"Still not dressed? Let's go, we've got things to do, people for you to flash."
Gretchen laughed nervously, but pulled on panties, jeans, bra, and a t-shirt. As she got her shoes on Petra looked in her closet. She came out with a 3/4 length raincoat, saying that it was raining out. They went downstairs and ran through the rain to Petra's car. As they drove across town, Gretchen asked what they were doing. Petra told her not to worry, but that Gretchen needed to strip down and only wear the raincoat.
"You weren't kidding about the flashing, were you -- I'm gonna be like some guy in a trench coat," Gretchen laughed. Petra just smiled mysteriously. Gretchen dutifully peeled off her clothes, and wrapped the raincoat around her. The fabric felt rough on her bare breasts, and she felt her nipples harden. Soon Petra pulled into the parking garage of the Museum of Art. Gretchen had not been here in ages. It wasn't a big one like Chicago or New York, but it did lend some culture to the city, and as she remembered, it had some decent stuff.
They got out of the car and started walking to the museum. Gretchen was instantly excited just from the walk. The feeling of the wind blowing up on her recently shaved sex was incredibly intense, and the feeling of the raincoat liner on her nipples kept them hard and sensitive. They got into the museum, and Petra showed a member's card to get them both in. Gretchen had no idea that Petra was a member. One more hidden side to Petra. The museum was quiet, and they often had a gallery to themselves as they walked.
In the third gallery they entered, Petra stopped and stared at a painting of a nude woman. She whispered in Gretchen's ear. "Wait until we're alone here, and then go stand next to that painting and flash me." Petra pulled a camera out of her purse and they waited about 30 seconds, and the room was empty. Gretchen walked to stand next to the painting, turned to face Petra, and opened the coat, flashing her boobs and pussy. Petra snapped off a couple pictures, smiling at Gretchen. In the next gallery it was a still life of flowers that Petra wanted in the picture. She told Gretchen to spread her legs wide for that photo. The next time Gretchen stayed facing the wall and lifted her coat over her waist and thrust her butt out as she looked over her shoulder back at the camera. All the posing and sexiness was turning her on, and the poses got increasingly dirty. She squatted down with her knees spread wide showing her sex. She cupped her breasts, holding them out to the camera. She bent over and used her hands to spread her butt cheeks. She was flushed red, and knew she was gushing wet from all the excitement. The anticipation of waiting for the room to empty, of finding a room with no security, made it all the more exciting. There were a couple of times where people might have caught them, but other than some funny looks, no one said anything to them.
They found a room with a nude statue in it, and Petra said it would be great for her to have the same pose. Gretchen was very nervous about leaving her coat with Petra. What if someone walked in? It would take a long time to get back and get her coat on. After a lot of discussion, Petra talked her into it. They waited until the room was empty and Gretchen peeled off her coat, handed it to Petra, walked to the statue, and assumed the same pose. Petra had snapped of two or three photos when a man in a security uniform came into the gallery. Gretchen was horrified. She ran to Petra to get her coat, but the guy had clearly seen everything.
"Excuse me ladies, I'm sorry, but you can't do this here," the guard explained, "this is a family museum." Thankfully, he didn't seem angry. He was a young guy, maybe college age, and he seemed uncomfortable that he was having to ask them to stop. Petra immediately launched in to a totally bogus story about being an art student, and that she was doing this as an art project. Nudes with nudes, that kind of a thing. The guard listened to Petra, but he kept staring at Gretchen. Eyeing her cleavage, or looking over her bare legs. He clearly was conflicted, part of him needing to do his job, part of him interested in seeing more of a naked Gretchen . After Petra went on for a while about how important this project was to her, he seemed to crack.
"I'll tell you what," he said, "I think it's a cool project. Maybe I can help you out. I can go to each gallery, make sure there isn't another guard there, and watch out for people coming. I don't mind you doing it, but if people see you I could get fired, so you need to only go when I say. Okay?"
"Oh thank you Tyler!" Petra gushed, getting his name from his nametag, "that would be so awesome." Gretchen smiled at him shyly, which made him smile back awkwardly. He was kind of cute in a nerdy kind of way, Gretchen thought to herself.
