Her mouth was doing a great job on his cock! As for me, I would limit myself to the mouth - so relaxed to myself and catching a buzz. If even a gulp and lightly massage his lips after that - full flight! I love it when a woman can work with her mouth. And on the second run, you can already fuck her!
She's a blonde with a nice ass. You can't scare her with a big dick. Dude was lucky to get his ass in such a beautiful girl, it went like clockwork. The dude apparently got into the excitement and decided to shovel more sperm in her ass.
