The lady is of course old and fat, her tits are saggy too. But for all that, I would have loved to spend time with her, she was still very attractive. Personally, I wouldn't go down on her tits. It's much nicer to fuck her in the mouth a little at the end and cum in the same. It's especially nice when a woman works you with her lips for a few more minutes after you cum. The pleasure just makes your eyes pop out!
The sister is really very horny, to get her brother into bed like that, it would have to be such a hen. Although in principle the brother is also particularly pleased with such sex, because they fucked just amazing and that can not take away from them. Although I think that such a mad fuck they will have more than one time, we can only wait and see, because she 100% dreams of his thick cock.
