Carrie was expecting a gang bang. So she put on a candy thong and awaited her fate. She was in public, but she didn't care. Her huge boobs were uncovered, as was most of the rest of her body. She strode down the street and unlocked her door. Her boyfriend and five of his friends jumped out. All of them were naked. They locked the door behind her. They ate all the candy off her thong and discarded it. Six penises were shoved into her pussy. They were all hot. One of Carrie's boyfriend's friends, Jake, pulled out and fucked her asshole. Eventually, they all were tired. They slept like that, 5 in her vagina and 1 in her asshole.
