After I had cleaned up the mess I left, I headed for the shower. We only have a shared bathroom, and we don't have a lock, so there have been a few em...arrassing incidents when I was younger. I hopped in to the shower and started the water running. After a while, I heard my sister knock on the door. "Chris, is it okay if I use the bathroom quickly?" she said, urgently. "Sure, I'm in the shower, just make sure you don't flush." "Okay, thanks!" I heard the door open and close, then the soft. I did, in a way, feel excited satisfaction at having done such an obscene, crude thing, but I'd really wanted more fucking.I pulled my panties up and was adjusting my skirt when I jumped with fright at hearing a voice just above my head, saying, "how was the slut, a good fuck?"I looked up staring in disbelief. A guy was looking over the adjoining wall of the cubicle, and had apparently been watching us fucking.The guy who had taken me there, also looked up in surprise, but then simply broke. The gag was a ring gag with a removable penis gagwhich had already been removed. Behind me I heard one of them unzip their fly and Irealized I was about to be anally fucked for the first time. I was about tolose my anal virginity to a bunch of strangers while I was outside, tied up onthe side of a trail. I had played with anal toys and enemas before but hadnever been with a man before. In the position I was in I could see my emptiedback pack. To my horror I could see the unopened box of. I went to the site, called "Girlfuss" and had to subscribe to see anything. After endangering my credit-card to the tune of about thirty bucks and scanning thousands of thumbnail images, I located her sets under the alias, "Blonde-bomb" and down-loaded everything available. There were about two-hundred photos, most in color; varying in theme from demure panty-shots, to out-right vulgar fingers-in-spread-pussy shots. As familiar as I was with my wife's body, I have to say, these pictures still.
