As my best friend's babysitter, I've always had a thing for this college cutie with the big ass. Today, I finally make my move. She's hesitant at first, but her body responds to my touch. I start by squeezing her thick ass, then slip my hand under her skirt to feel her wet pussy. She gasps but doesn't stop me. I spin her around, bend her over the couch, and push her skirt up to reveal her luscious ass. I slap it, making her yelp, then pull her panties aside and slide my cock into her. She's tight, but I push in, filling her up. She moans, and I start to fuck her, steady and slow at first, then harder and faster. Her big ass bounces with each thrust, and I can't get enough. I fuck her until we're both spent, then collapse onto the couch, her big ass still in the air, my cock still inside her.
