The guy knows his stuff - he slowly and methodically fucks her in the anus! And he doesn't care how swollen her labia are and how she caresses them with her fingers. I think the woman just needed a penis in her vagina, or alternatively double penetration with the phaloimitra. And who said the woman even reached orgasm? I only saw the guy come down her anus and that's it!
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.
