It's not clear why the second lady is so indifferent to a fuck in front of her? And the little black lady - they took it out on her ass and she continues to lie there quietly and doesn't run to the bathroom to wash up? Maybe she means that she fantasizes about sex, but nothing really happened.
Why wouldn't my sister want to get her ass handed to her brother? Dude really had a good time with his sister, I honestly envy him!
