A couple of months ago I posted a story about me pranking my roommate. I assumed that it would turn into a prank War, but it turned into me and her being naked around each other a lot. We are usually just naked around the apartment. But a few weeks ago she gave me a dare. The dare was to go to a nearby park wearing only a small dress with no underwear and try to flash as much as possible, but try to make it look unintentional. I agreed to do it but I wanted my roommate to do the same thing. I told her that I didn't think it was a good idea to go to a nearby park just incase we see someone we know. So we found a park about an hour away. I went to my closet to look for the perfect dress. I ended up found finding a short blue summer dress. Then the next day we set out on our adventure. On the way there we stopped at a rest stop to use the bathroom so while I was waiting for my roommate to be done, I went over to a bench and sat in a way that my pussy was clearly visible. Then when my roommate came over, her jaw dropped. We got back in the car and continued the drive. When we got there, there was almost nobody there. So we got out and found a nice and secluded area. we decided to take turns flashing so for my first one I grabbed the front of my dress and flapped it a little bit to act like i was hot. After a few seconds of doing that I picked it up a little more and flashed my pussy. Then for my roommate's flash, she started running around the area we were at. While she was running she was bouncing her ass to make the back of her dress fly up. Keep in mind that throughout this we kept the flashes about 10 minutes apart. Next i had a great idea for the next flash. So i told my roommate I would be right back. I drove out to the dollar store and bought a small spool of thread and some tape. Then in the parking lot of the park I taped a piece of string on each side my dress and taped the other end on each arm. So when ever I would put my arms up my dress would fly up. Then I walked back to my friend and as I was getting back to our little area i put my arms up and pretended to yawn. My dress went all the way up to my tits so the whole bottom half of my body was on display. My roommate was shocked. After that we decided to turn this into a contest, who ever flashes the most by the time we were done Wins, And the loser has to be naked until we got back to the apartment. Then my roommate loosened the top of her dress and started to jog around. As she jogged, her dress started to fall down and showed her tits. She instantly stopped and pulled it back up and walked back. She thought she had this the bag, but I Wasn't going to lose. I then took off my dress completely and ran over to a small cluster of trees near by and crawled back. Then my friend took this one step farther and completely stripped and walked around a small track for about 3 laps. There was basically nothing I could do to top this so I accepted my loss. My roommate told me that I could keep my dress with me in case there was an emergency. So we started to drive back and many cars were driving by slowly. (wonder why) When we got back to the apartment I really didnt want to get out of the car. My roommate felt generous so she parked in the parking garage. when we started walking to the elevator I was covering my parts, but she said I was not allowed to cover up. Instantly when we got back into the apartment my roommate stripped and we watched TV for a while. I'm also starting to think that she is bi because she has had multiply boyfriends but she likes to play with my tits while we watch TV.
