It's simply a latex cock ring, with scrotum ring.
OOPS. I called it a "cock saddle". It is actually called a "cock sling".

How are you viewing them?
Reddit on a desktop/laptop, their official mobile app, a third party app, or a mobile web browser?
On the official app (which is junk) you often need to tap on the actual link and visit the site the video is posted to in order to get audio. Viewing the embedded video on Reddit doesn't work unless you happen to see a little speaker icon.
I recommend a third party app. If you're using an Android phone, Sync is as good as it gets. Everything just works, it's customizable, and reddit's shitty ads (promoted posts and stuff) are all gone.
Play store link: Sync for reddit
I think Bacon Reader is the popular one for IOS?
It's the Pipedream Mega Masturbator. It's amazing, highly recommend it. Shop around for the best price but here's a link for reference. There's a smaller version and a bigger version you might see. I got the bigger version. http://www.amazon.com/Pipedream-Products-Mega-Masturbator-Silly/dp/B006W00E5S/ref=cm_cr_pr_product_top?ie=UTF8
