Author's note: I just realized from the comments that not everyone on Literotica knows who Gretchen is. She is a perennial contributor on Indian Outlaw's ASN board, and I wrote this story for her. Petra is totally my own creation, and all the events are imaginary, but Gretchen is very real. Like I do, she loves to see your comments, loves to find out what people like about her story...
========
Gretchen had not slept very well. She kept thinking about her orgasm in the car. The whole thing with Petra was very weird. They had been friends for a very long time, and they had been through a lot. From being in different crowds in high school, from Petra going off to an Ivy League while Gretchen staid closer to home, to ending up back near each other after college, but they always stayed close. And it wasn't like they hadn't always talked about sex. Well at least Gretchen always did, so Petra knew more about Gretchen than anyone did. But the last few days were way beyond that. Part of Gretchen was totally humiliated, and she worried what Petra must think of her. Part of her was obsessed with going further, and was dreading that Petra might stop.
She continued her new habit of staying naked until it was time to leave. She made coffee, showered, picked out her clothes, and did everything else she needed to while she was still naked. She pulled on a dark blue bra and thong, a white blouse with vertical blue stripes, and a skirt that didn't quite come to her knees. Once she was dressed, she headed to work. She drudged through the workday until Petra called her at lunch.
"I have some stuff going on this evening, but let's go for a jog late tonight," Petra suggested. They agreed that Gretchen would pick Petra up at about 8:30. The rest of Gretchen's day was uneventful. She finished work, went to work out, stopped for some Chinese takeout on the way home. As she walked in her door, she decided the naked in the apartment thing should continue. She got undressed, and then ate the takeout as she surfed. She casually stroked her naked body, and even rubbed her kitty as she passed the time.
She put on her running stuff at about 8:00. She put the thong back on and a sports bra, a tight fitting sleeveless top and some loose fitting running shorts. She popped downstairs and into her car and drove over to Petra's. Gretchen called her right before she got to the house, and Petra was waiting on the street. She tossed a workout bag in the back seat and then climbed in the passenger seat. She had a loose fitting white T on with some long shorts. Gretchen smiled at her friend's choices of clothes. Petra was really very cute with a petite figure and beautiful olive skin, but she never put any effort into showing herself off. Gretchen had tried to get her out of her shell a couple times in high school, but it was obvious that Petra liked her shell. She had Gretchen as a good friend, but she wasn't really interested in being more popular.
Gretchen asked where they were going, and Petra gave directions. Petra told her that they would go to a forest preserve out in the suburbs. It would be quiet at night, but also safe for a couple girls on a jog. They pulled into the unlit lot, and were the only car. Gretchen parked and they started off down the trail. The moon was close to full, and it was easy to find their way. With her longer legs, and frequent workouts, Gretchen soon got in front of Petra. Petra asked her to stop a second.
"We need to slow you down a bit. Give me your bra."
"I can't run without a bra, they'll bounce all over"
"That's the point, it'll slow you down".
Gretchen realized this was number 4, so she quickly worked the bra out from under her shirt, and handed it over. They began to jog again. She held her boobs as she ran, but Petra said that defeated the purpose and told Gretchen to keep her normal stride with her arms at her side. Gretchen had to slow down quite a bit, but found a pace where her boobs didn't fly all over the place. Petra kept alongside her, but was breathing hard. Soon she asked to stop again.
"Okay, not enough, you're still going too fast. Give me the shorts too."
Gretchen was ready this time, and just peeled them off. "Be careful, the car key's in those," she warned. Petra took the key out and put it her sock. They jogged a while longer, Gretchen savoring the idea of running in a thong. There wasn't anyone else here, but if there were, they could have got a great view of her butt. Soon Petra made her stop again, and before she could even say anything, Gretchen peeled off her top. Petra just giggled and told her that she was getting good at this.
Going back to jogging was exhilarating. She was running out in a park, almost naked! Granted she still had her thong, and it was dark out, but it was close enough. The jogging was starting to make her sweat, and her skin glistened in the moonlight. Her boobs were bouncing with every step, but she found a pace that kept that from being uncomfortable, and she allowed her mind to wander, relishing the freedom of what she was doing.
Soon Petra took the final step, and with a quick motion Gretchen pulled the thong off and stepped of it. She handed it over to Petra, and began to run, completely nude except for her shoes. It was such a rush! She was exuberant as she jogged with Petra by her side.
Suddenly they heard some loud laughing up ahead. Gretchen hissed some profanity, and hunched over covering herself. "Don't panic," Petra was giggling again, "it's probably just some high school kids out drinking. They'll be too busy partying. We'll just cut across the field and they will never know." Gretchen got back up and followed her across the field, around the noise from the teenagers. She thought she heard someone say the word "naked" and then a lot of laughing, but no one followed them.
They passed the halfway mark and followed the loop around back to the car. By the time they got back Gretchen had worked up a light sweat, and Petra was breathing hard. "You need to get more exercise girlfriend," Gretchen teased her.
