Sometimes I babysit for some spending money. I had a job the other night that turned out to be more than I expected. The brats were in bed and I was horny. I was not expecting the parents home for three more hours so I decided to be a little naughty. I got completely naked and climbed onto the couch. I leaned onto the back of the couch and stuck my ass out. I like to do this when I masturbate because it makes me feel like I am in position for a good fucking and well that gets me so wet. I reached around and started fingering myself. Oh it felt so good. I was almost ready to cum just a few minutes later. Just then the door opens and the parents walk in. I was so embarrassed. As it turns out though I had no reason to be nervous. The parents liked what they saw so much that they decided to join me! The father came up behind me and violently rammed his big hard cock straight in my ass. I was about to cry out from the pain when the mother straddled my face and shoved my mouth down into her pussy. For the next several hours we fucked and sucked each other. It was so much fun! I babysit for them four nights a week now! I try to be in a new position every night when they cum in!
