Friday Nights

When I was a teenager my mum and step dad regularly went away for the weekend. My older step sister would come home from college for the weekend to look after me and usually brought a couple of friends home from college with her. They loved to play games with me and they had a favourite game for Friday evenings. To play the game my step sister and her friends required me to wear a seriously short dress made of thin white cotton which they had bought for me - and absolutely nothing else. They had deliberately bought a dress which was too small for me and which tightly hugged the curves of my body. There were buttons right up the front of the dress but I was allowed to fasten only two of the buttons. I have to admit that I looked and felt incredibly sexy wearing that dress like that.
They would then take me to a busy bar - most often one which was packed with students - and find a table or somewhere to stand well away from the bar counter and bar staff - and usually amongst groups of guys who had already had too much to drink. I was always given several shots of alcohol in quick succession and then given my instructions for the evening which always followed a familiar pattern.
My step sister and her friends would have been watching the groups of guys and would select one of the groups of guys - usually the liveliest and most boisterous. I became pretty good at predicting which of the groups they were going to send me over to. My nipples always firm up and harden very easily and quickly and by this time they would be clearly visible through the thin white cotton of the dress and I would be more than a little damp - I knew exactly what was going to happen next and the alcohol and anticipation and excitement had already kicked in.
My step sister and her friends would give me crazy little lines which were quite provocative and designed to get the guys attention fast. Things like "my friends and I were wondering which of you guys has the biggest cock" or "my friends were wondering if any of you would like to fuck me". I would then be sent over to the group of guys and to stand as close as I could get to them and to say exactly what I had been told to say. I never failed to get their full attention ! My instructions were to let them look me over and to then push into the group and settle on the lap of one of the guys - as close to the middle of the group as possible. As soon as I had settled on his lap I had to kiss him passionately and then very obviously and very slowly and very provocatively unfasten one of the two buttons on the front of my dress which remained fastened. As you can imagine, almost immediately, there were hands all over me - often quite roughly - and the single remaining button on the front of my dress rarely remained fastened for long.
There was something about the mix of alcohol, the way I had to follow the instructions which were given to me by my step sister and her friends, the dress, being the centre of attention of the group of guys, being virtually naked, feeling their hands all over my body - and believe me they did find their way everywhere very quickly - roughly exploring every centimetre of my body - breasts, nipples, bum, thighs, between my legs - fingers pushing inside - in a busy bar with people watching ! I felt totally wild !
My step sister and her friends loved to watch everything which was happening to me and loved to see the reaction of the guys. Eventually, when they thought that things had gone far enough, they would come over and tell the guys it was time for them to take the filthy little slut home to be punished. They always asked the guys what they would like to do with me if they were to come home with us - although that never happened.
