Mercedes Mac, my gorgeous stepsister, called me into her room for help. She was struggling to pull up her super tight skinny jeans. Her thick ass and wide hips made it almost impossible. I walked in and my eyes immediately locked onto her perfect body. “Help me bro, these pants are killing me,” she said, bending over in front of me. I grabbed the waistband and started pulling, but the jeans were stuck. As I pulled them down, I revealed her sexy pink panties disappearing between her juicy ass cheeks. I couldn’t hold back anymore. I slowly slid her pink panties to the side, exposing her perfectly shaved, tight, peach-like pussy. “Fuck… your pussy looks even tighter than those pants,” I groaned. Mercedes looked back with a naughty smile and pushed her ass towards my face. I buried my tongue in her smooth, hairless slit while squeezing her big, round tits that were spilling out of her top. She was soaking wet. She turned around, dropped to her knees and took my hard cock in her mouth. Then she climbed on the bed, still wearing the tight jeans around her thighs, and spread her legs. I pushed my thick cock into her incredibly tight pussy. Mercedes moaned loudly as her narrow walls gripped me. “Oh god… you’re stretching my little pussy so much!” she cried. I fucked her hard in doggy style, then flipped her over and pounded her deep. Her big sexy tits bounced wildly with every thrust. Finally, she got on top and rode me like a slut until I couldn’t hold it anymore. I pulled out and shoved my cock into her mouth. Mercedes sucked eagerly until I exploded, filling her warm mouth with thick cum. She swallowed and smiled: “My pussy really is as tight as my pants…”
