Ass is just awesome, who can refuse to put such a lady in the anus. Especially since she is so excited about it. And I don't need those silicone tits, what's the use of them. Licking the anus isn't my thing either. A man should pull a woman into every orifice of her body, it's normal and natural.
Judging by the way her sister told her brother off at the beginning of the video, she must have been decently older than he was. But that care with which she helped relieve him makes me wish I had an older sister.
