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!
This blonde didn't mind fondling herself, from what I could tell. So it's not strange that she's willing to take strangers inside her and agree to have sex in a van. What they did to her afterwards was a mundane matter.
