Older Sister

"It's kind of unusual, I know, but I saw my baby sister lose her virginity at 18 right in front of me a month ago. We told our mom we were babysitting down the street, but I had lined up a double-date with the the neighboring town's quarterback and his homey. Behind a Sonic, I got a little tipsy in his tinted SUV and started going down on him in the front seat, while sis and her date stared at us from the far back. She's always been unlucky with boys. It led to me riding him completely raw after he unknowingly slid my panties down. I soon realized what I was doing and told him to pull out, but that's when I heard my sis yelling. She was getting it doggie in the back seat by his friend! We both screwed until we totally came."
