Cumming when strangers called me "slut"

I was picked up to have a photo activity in somewhere near Taipei, it seems in suburb of other city in taiwan. After taking nude pictures of me , club members played a dirty practical joke on me. They tied my hands behind me and dropped me in the middle of nowhere. Then they asked me they will wait for me just along this road a kilometer away.

In other word, I have to walk along this road naked and show my body to everyone who passed by me. I wish I have luck to
avoid meeting anyone who wants to screw me.

Unfortunately,  I met a mid-age old guy when I was halfway there. He was surprised that a young lady naked and tied up along the road. He thought I was a rape victim and wanted to drive me to police station to take a further care. But I told them it's just a game between me and my college friends. I thought he will realize and go away immediately . However, he keep chatting with me and started to pinch my tits and nipples as he wants.

It was so exciting to be screwed up by such a ugly-old-horny stranger,  compulsory breast massage makes me so embarrass. Photo members cheer up and toast to the old man when I get there. Those members pleased old guy to keep pinching my breast and tried to touch my pussy in front of them. They really enjoy the show.

My body can't help shaking when my pussy put in a fat thumb. This was a filthy sex way, but both me and members feel so exciting. Those members didn't just wait and see, they called my name one by one. "cheap","Taiwan pussy","Taipei slut", "Taiwan whore","huge tits, no brain"....

Finally, I was coming in front of them when someone called me "slut". I was even squirting all over. It's so strange that I feel a little exciting when someone called me "slut" or something dirty when sexing, am I turned on by those sexual events ?
