And felt a shudder of - something! It was partly revulsion, and partly delight, at the sight of the two young men in their car, sitting next to hers, ...taring admiringly at her. She felt her cheeks redden in humiliation - that she should become the object of men's desires! And yet...Somewhere, deep inside her, Petra realized to her absolute shock, that she was starting to feel curious. A strange curiosity about these two young men stirred within her, giving rise to warm tingling sensations,. I finally got to their house and walked in and walked down the steps. I looked across the room and their they were naked and she was tied up and he was screwing her and pounding her very hard. She was screaming in delight. I walked over and she told me to get comfortable. I undressed and walked over to them. Bill untied one of her hands and she reached out for my cock. I kneeled down and she grabbed it and pulled it towards her mouth as Bill was fucking her missionary still. She really knew how. I was thinking, "at least I got my gas money back". I noticed she had a box of rubbers in her purse but I shucked it off. Just then my buddy came out to see what was going on and why I hadn't left yet.When she saw him, she just pressed her entire body against mine and pushed back until I was pinned between her and they car. She grabbed my behind the neck and stuck her tongue in my mouth. She must have just put a piece of gum in because it was really fruity tasting. I went with it though grabbed. I lingered at her asshole, licking and poking at her tight hole with my out stretched tongue. I could feel her twitching and shivering as I replaced my tongue with my finger. She leaned forward and my finger slide easily into her slick asshole. I teased her a little, tickling her pussy with my other hand while I tantalized her ass with my finger. My cock stood straight up in my lap like a quivering flag pole in the wind.I stuck one finger, and then two fingers into her into her drooling snatch.
