It does look fine in my opinion. I like that you add your own titles and descriptions, I am sure it will pay off in the future. Here are some things that you should take into consideration. I see that you are repeating your tags in the videos. For example, you should have the ones like milf facesitting, ebony facesitting, amateur facesitting in one video, because it will be considered stuffing by Google. You do not need to mention facesitting at all if your site is about facesitting. It would be better if you would just have used the categories you are doing now and do not use tags at all or only when it is appropriate.

Another thing you should do is to install the plugin named Shortlinks for your affiliate links. It will not only make them easily manageable, but that way they are not blocked by AdBlock so your visitors can see and click on them. You should also host all ad banners on your site, change the names for them from banner.jpg to something more random like a11.jpg and also resize them for a few pixels so they are not using the standard dimensions. All of this will help you to bypass ad blocking tools.

Generally, you should add them everywhere, but the key here is to not overdo it, so do not use the same keywords more than once in your description and in your titles.
