She may look innocent, and because she's only 18 she is, but MacKenzie is trying her hardest to expand her sexual horizons. "I had a threesome with my ex and a girl friend of his. We spent hours just sucking, licking and fucking each other. I also had a fuck buddy who tied my hands behind my back with my hairband and choked me while I was cumming. I've had a lot of experiences for girls my age, I think."
