This developed into me doing some more daring things that got me in some trouble. When I was 14 I was on a school trip and staying at a motel. It was late one night and I had been getting really turned on by all the men earlier that day checking out us girls everywhere we stopped at (for gas or food or anything). So I decided to leave the room and walk downstairs one floor to the vending machine. But I was going to do it only wearing a tshirt over the panties I was wearing (some kind of skimpy bikini style panties). The shirt wasn't quite long enough to completely cover and someone could see the bottoms of my panties.
Going out and down the stairs the hallways were empty. But when I left the vending machine I notice a guy at the end of the hallway coming my way. I slowed a little bit but really didn't want to let him too close, just a little tease. I got to the staircase door and opened it. I wasn't even three steps up when the door behind me opened. I got nervous and just began heading up faster, but the guy said something like, "excuse me." It was a polite voice and I stopped and turned around to see what he wanted. (I was trying to act casual). He was in front of me before I knew it and made some remarks about how he really liked seeing me wearing so little. He got really handsy and grabbed my ass and started groping me. I told him to stop it and he stopped and I ran on up the stairs with him standing there. I got back to the room and was pretty scared but still really turned on. I've never forgotten that experience and although it was a close call it has been an exciting memory to recall.
