Alexi Star's petite frame quivers as she feels her lover's thick cock pressing against her tiny asshole. She's never taken a cock this big back there, but she's eager to try. She lubes up her tight hole, pushing a finger inside to stretch herself. Her lover watches, jerking his cock as he waits. When she's ready, he pushes inside, his fat head stretching her ass wide. Alexi cries out, but she loves the feeling of being filled so completely. He fucks her hard, making her ass jiggle as he pounds in and out, before pulling out and covering her back in his hot cum.
