Her assets to her advantage, and your disadvantage Shrunk in an Amusement Park chapter 7 by Louka31

As the ride came to an end and the automatic bar rose, the Hispanic girl didn't move. You still felt all of her weight pressing down on you from all angles when you heard her muffled voice ask the attendent "Can I ride it again???" He glanced back at the line, which had grown fairly short, then back at the girl. She batted her dark brown eyes at him and smiled and of course he relented.

The girl was so excited that she was able to once again go on her new favorite ride, she danced to herself in the seat of the ride....rubbing her butt back and forth across the cushion. Even though you were already completely flat and plastered to her smooth flesh, her movement had the effect of slowly scraping you off and back onto the seat. Carla (the girl) then stands to shout to her friends who have gotten off the ride, motioning to them that she'll meet them by the exit after she goes through once more. She then plops her firm butt right back on top of you. In the meantime, you had slowly started to regain your form from your flattened, battered, mashed shape that you had taken from the first ride and the grinding that followed. Now you found yourself once again crushed between the barely forgiving seat and her soft, muscular butt.

After a few moments that were the most peaceful you had since the roller coaster, you felt the familliar drop in the pit of your stomach as the ride started to lift. Again the rise of the ride added pressure to Carla's already heavy weight pressing down upon you until it reached it's peak, where she actually lifted off of you a few inches before starting down again. The fall happened so quick you didn't have time to prepare yourself for the impact you knew was coming when WHAM!!! Carla's butt slammed on top of your body with more than three times its normal impact. Then it started its second lift. This continued for what seemed to be longer than the time before. Apparently swayed by Carla's charm, the ride operator extended this trip a few extra lifts. WHAM!! WHAM!! WHAM!!!! Every time her butt landed on you you compacted slightly more.

Eventually, the ride was done, and Carla got off. Without your ability to grab onto her bikini bottoms, you remained plastered to...
