I live in an apartment complex that has two apartments on each floor. We moved in a week ago and discovered there are two cute sisters living in the one in front of ours. I've been dying to meet them, there both hot but the older one is really sexy. It was saturday mourning and my parents had left for work and I was hanging around the apartment in the nude. I heard a tump on the front door and went to check threw the peep hole an saw nothing. So I opend de door slightly and looked out. That's when I made the worst mistake of my life. I went out to look down the stairs to see if anyone had just gone by, as the door slamed shot behind me. I turned white when I realiced I was locked out of the apartment, naked as the day I was born. I just sat on the strairs not knowing what to do, when I heard the door open from the girls apartment. They heard the loud bang of the door and came out to investigate what it was and saw me sitting there with my hands over my dick. She had this smile on her face as she asked me what I was doing naked out in the stairs, so I told her what happed. By now her sister had come out as I was trying to explain my situation. She said "fancy meeting you this way" as I instantly turn bright red. She told me to come in to her apartment and said to not worry her parents weren't there. I din't have much choice, so I went inside with my hands in front of me and my butt out in the open. I was standing in their living room as they were laughfing and deciding what to bring, so I could cover myself. They were taking their time and just extending my embarrassement and having fun with the whole situation. She went to the room, as her sister sat there looking at me, and and came back out with a pair of panties. She handed them to me smiling and knowing they weren't going to cover much of my hard dick. They watched me put them on and shore enough, half my dick and balls were poping out the sides. She asked me if I wanted a towell but had to take them off in front of them. "We've seen everything, so might as well show us your hard dick. I wasn't bother by it anymore, so I took them off and let them look as much as they wanted. After all, I was going to spend most of the day naked with a towell around my waistwith them, thinking whos parents were going to arrive first. It turns out I got embarrssed all over again in front of both our parents.
