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!
His brother fucked his insatiable sister in all her slits. She moaned from his cock so that he almost cum himself.
