First-time ass play with my girlfriend in a cowgirl position

I've always been a big fan of ass play, but my girlfriend was a bit hesitant about it. She's a total babe and I knew she'd look amazing with her ass stretched out. So, I decided to give it a shot and see if I could convince her to try it. I started by teasing her with my fingers, slowly working my way in. She was initially hesitant, but the pleasure soon took over and she was moaning with ecstasy. I could see her ass gaping and shaking as I pounded her harder and deeper. I even got her to ride me in cowgirl, giving me an amazing view of her ass bouncing up and down. The sight of her ass stretched out was enough to make me cum. I couldn't believe how hot she looked and it was definitely worth the effort.
