I was supposed to be the third wheel, but as I walked in on my boyfriend and best friend fucking, I knew I was going to be the star of the show. I stormed in, but instead of leaving, I joined. My boyfriend's cock was hard and ready, so I pushed my best friend down, making her lick my pussy while he fucked me from behind. I rode his cock, grinding my hips as my best friend watched, jealous. I came, my pussy clenching around his cock, before pushing him out and mounting my best friend, making her eat my pussy while I fucked her with a strap-on, giving her a taste of her own medicine.
