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!
At first she rubbed her lips against him, and then she leaned over and he rubbed her pussy where she needed it, making her squeal and moan like she was fucking for the last time, she felt the payoff.
