This story happened two years ago and it was the best night of my life. So far only the people involved know about it and I've been waiting to find someone to tell it to without the others finding out. For that reason I have had to change the names but that doesn't matter.
I moved in to a new flat with my girlfriend in the suburbs, we had been together for a year and decided we were ready to live with other, at the same time my girlfriends' best friend, Sally was moving in with her boyfriend too. I still fancied the ass off my girlfriend; she was in my opinion the perfect woman. Around 5'6" shoulder length auburn hair, brown eyes, tight bottom and tits that were just the right size. Her Irish blood gave her a sexy pale complexion with rosy cheeks and lips that loved to suck cock.
However, as we started to get to know Sally and her fella, my eyes naturally started to wander. Sally, was the opposite of my girlfriend Erin, she was about 5'11" long dark hair, small tits but perfectly formed in the tight T-shirts she used to wear and the rounded ass that was just asking to be fucked. After a while, I started to think Sally had noticed me spying on her ass and tits as every time I went to visit she wore increasingly revealing clothes.
One night when we went for a barbeque, it all started innocently, she was obviously flashing me her thong over the top of her jeans and I even caught a glimpse of her pussy hair as she "accidentally" forgot to do up her top button on her jeans. After a few beers and burgers we started playing cards, who ever lost had to do a dare. It was a pretty slow game to begin with; no one wanting to cross the line, the worst that had happened was me having to wear one of Sally's dresses. Then I lost and opened my dare "swap clothes with another player" Sally was wearing her boyfriends jeans and jumper by this time and they weren't giving me the view I usually look forward to when visiting so I suggested we change.
She wouldn't let me change in the same room as her, which was probably a good thing considering the size of my cock, and that was just thinking of her in the dress. When she appeared she had clearly put a little extra make up on and made her self look good. Maybe she knew why I changed clothes with her. When we sat back down, I couldn't take my eyes off her, the dress was sleeveless and cut just enough to show me that Sally had ditched her bra. When she leant forward, I kept getting a peek of her perfectly formed pink nipples.
I didn't care if my girlfriend had caught me spying by this time, I was hot and I wanted to fuck Sally. Little did I know that my girlfriend was paying a little bit too much attention to Sally's boyfriend Dave to care what I was doing. Dave was similar to me, around 6' well built and a little bit of stubble. We both played football so we were pretty fit. I knew he fancied my girlfriend, but I fancied his so it never bothered me. Just as I was thinking about how much I would love to see Sally's pussy, she opened her legs discreetly and flashed me a look up the bottom of the knee length dress. She had definitely dressed up, I knew from the thong flashing what she was wearing before and this was different. Pure white lacy panties with what looked like a nice moist patch on them.
