This is one of those cases where you can't tell if someone is taking advantage of someone else. Both the brunette and the guy both have a villa, so while having sex, they're really having sex, not fitting in with each other. It's worth noting the brunette's beauty, good model looks.
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.
