Fortunately, I was able to find videos online for both scenes featured yesterday in the gif loops. The first one with the cock riding features Esteban and Doriano. The top here is rather skinny, and his huge cock suggests that's where all the protein ends up in his body.
The second features mulehung Austin Wilde with a babbling newcomer named Riley who is allegedly a virgin and surrenders his cherry for the first time ever here in this scene. I can't say I'm convinced by what I saw here that he's never been fucked before, but it's nonetheless a very hot scene.
If you'd like to watch either or both of these videos on their source webpages, or to download your own free copies, for the Esteban and Doriano scene, click here. For the Austin Wilde scene, you'll need to click here. You may download a free copy of the second video on the Pornhub site, where you must first sign up for a free account.
