I've become a size queen

For the longest time I was satisfied with an average sized dildo. If it was 6-8 inches long and average girth I was happy. But then I bought an 18 inch double headed one for deep penetration. Well the length was good but the width was lacking. So I got a 12 inch b**st that's as thick as my forearm. When I sit on that monster and feel the balls against my ass the pain is exhilarating.I feel so full and pleasured I start to shake, and that causes the huge cock to move around. When I push it out my asshole gapes. Laying there afterwards my hole burns and my body shakes. The soreness is so worth it.
