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!
There are those who love thrills, it's boring with just one guy, but with three just right. Minute warm up so that everything is good and spanked a young slut. Now that's a girl on fire, a triple hit!
